Answers

Answer 1

The ship will speed up while the engine is firing.

Whatever speed it has when the engine cuts off, it will continue at that speed (and in a straight line) from then on, because there's no force acting on it, so it can't have any acceleration.

That's the 3rd choice.

The total surface area of soles of his feet is 0.5 m²

We need to find the pressure exerted by his body on the ground​. The pressure is equal to the force acting per unit area. So,

[tex]P=\dfrac{1500\ N}{0.5\ m^2}\\\\=3000\ Pa[/tex]

So, the pressure exerted by his body on the ground​ is 3000 Pa.

Un prisma rectangular de cobre, de base igual a 36 centímetros cuadrados y una altura de 10 cm se sumerge hasta la mitad por medio de un alambre en un recipiente que contiene alcohol ¿que volumen de alcohol desaloja?

Answers

La respuesta correcta es 180 centímetros cúbicos o 180 [tex]cm^{3}[/tex]

Explicación:

El primer paso para saber cuanto alcohol desaloja el prisma es calcular el volumen total del prisma. El volumen se puede encontrar usando la formula V (Volumen) = B (base) x h (altura). El proceso se muestra a continuación:

V  = B x h

V = 36 [tex]cm^{2}[/tex] x 10 cm

V= 360 [tex]cm^{3}[/tex]

Finalmente, el volumen total del prisma debe dividirse en 2 considerando que solo la mitad del prisma fue sumergida y esta mitad equivale al volumen del alcohol desplazado.

360 [tex]cm^{3}[/tex] ÷ 2 = 180 [tex]cm^{3}[/tex]  

El volumen de fluido desplazado es de 180 cm^3.

Sabemos que el objeto va a desplazar su propio volumen de fluido. Por lo tanto, necesitamos obtener el volumen del objeto a, este es el volumen del fluido que eventualmente será desplazado por el sólido.

El volumen del sólido es;

V = 36 cm^2 * 10 cm^2 = 360 cm^3

desde que se sumergió a la mitad, volumen de alcohol desplazado = 360 cm^3/2 = 180cm^3

Answers

The answer is option c - It will divide in half to form two new cells..

Explanation:

The sentence that best describes what happened during cell growth is ;

( D ) It will become larger by taking in nutrients

As the yeast cells begin to grow ( i.e. cell growth ), they will require more nutrients and as they take in the necessary nutrients they will gradually increase in size ( becoming larger ) which is a vital sign of cell growth and development, which will be seen in the yeast cells as they undergo cell growth.

The production of offsprings with a mate does not describe an activity that occurs in cell growth.

Which statement correctly describes the charge of the nucleus and the charge of the electron cloud of an atom?

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options. However, the charge of a nucleus was discovered by Ernest Rutherford. The nucleus is located in the centre of an atom and it contains protons and neutrons. The protons are positively charged while the neutrons have no charge, thus the charge of the nucleus is positive because the neutrality of the neutron does not affect the charge of the proton.

The charge of an electron was first measured by Robert Millikan. Electrons are negatively charged subatomic particles that balance out the positive charge of the protons.

In a lacrosse game a ball is thrown with a force of 2000 N. The throwing force acted for 0.8

2. A driver of a car traveling at 15.0 m/s applies the brakes, causing a
uniform acceleration of -2.0 m/s". How long does it take the car to
accelerate to a final speed of 10.0 m/s?​

Answers

Answer:

2.5 s

Explanation:

The formula for acceleration is ;

a= v₂-v₁ / t

where ;

a= acceleration = -2 m/s²

v₂= final velocity = 10 m/s

v₁ = initial velocity = 15 m/s

t= time taken for the car to accelerate = ?

Applying the values in the formula as;

a= v₂-v₁ / t

-2 = 10 - 15 / t

-2t = -5

t= -5/ -2

t= 5/2 = 2.5 s

A ball is dropped from a height of 50 meters above the ground. What is its velocity the moment it hits the ground?

Answers

Answer:

The distance is 45m. (s)

Acceleration is 9.8 m/s^2 (acceleration due to gravity). (a)

We have to find the time (t)

By the 3rd equation of motion,

s = ut + 1/2 at^2 (here u is the initial velocity of the ball)

Since the initial velocity was 0 m/s, the formula becomes s = 1/2 at^2.

(substituting the values in the formula)

45 = 1/2 x 9.8 x t^2

45 = 9.8/2 x t^2

45 = 4.9 x t^2 (9.8/2 = 4.9)

(divide 4.9 on both sides)

45/4.9 = 4.9 x t^2 / 4.9

9.1836 = t^2

3.030 = t

So it takes approximately 3 seconds for the ball to reach the surface of the earth (neglecting air resistance). You can try the same with 50 m .

The velocity of the ball the moment it hits the ground is equal to 31.3 m/s.

What is the equation of motion?

Equation of motion has established a relation between the velocity of the body and acceleration of the body when the body is moving with uniform acceleration along a straight line. The distance traveled in a specific time has expressed a set of equations termed equations of motion.

The first equation of motion can be expressed as follows:

v = u + at

The second equation of motion can be expressed as follows:

S= ut + (1/2)at²

Where u is the initial velocity of a body, v is the final velocity, S is the distance, a is the acceleration and t is the time.

Given, the distance traveled by the ball, S = 50 m

and, the initial velocity of the ball, u = 0 as ball is at rest initially.

From the second equation of motion, find the value of 't':

50 = (0) t + (1/2)× (9.8) ×(t²)

t = 3.19 sec

Now from the first equation of motion, find the value of the final velocity of the ball:

v = (0) + (9.8) (3.19)

v = 31.3 m/s

Therefore, the ball hits the ground with a velocity of 31/3 m/s.

What does the triangle mean in physics?

Answers

Triangle is a mathematical symbol which the notes change in a quantity.

It is called Delta.

So Delta V=final velocity (-) minus initial velocity, delta T = time during the final velocity (-) during the initial velocity was recorded.

In physics, the triangle symbol (∆) typically represents a change or difference in a particular quantity.



A triangle is often used to denote the difference between two values of a variable. For example, if we have two values of time, t1 and t2, the change or difference in time can be represented as Δt = t2 - t1, where Δt is the triangle symbol indicating the change in time. Similarly, it can be used to represent differences in other physical quantities such as displacement (∆x), velocity (∆v), or temperature (∆T). The triangle symbol (∆) is a shorthand notation commonly used in physics to indicate changes or differences.

In terms of change in displacement, the triangle symbol (∆) represents the difference between two positions or locations. It indicates the change in the object's position from an initial point to a final point.

For example, if an object initially starts at position x1 and then moves to position x2, the change in displacement (∆x) can be calculated as ∆x = x2 - x1. Here, ∆x represents the difference or change in the object's displacement.

The magnitude of ∆x gives the overall distance traveled by the object, and its sign indicates the direction of the displacement. A positive ∆x signifies a displacement in the positive direction (e.g., to the right or upward), while a negative ∆x represents a displacement in the negative direction (e.g., to the left or downward).

Therefore, The triangle symbol (∆) is commonly used in physics equations to denote changes or differences in various quantities, including displacement, velocity, time, and more. It helps us analyze and quantify the differences between two values of a physical quantity.

Melissa my pet cow from childhood that i could ride like a horse had a weight of 0.65 tons. Philip my pet rabbit had a weight of 192 ounces. How many philips would it take to weigh as much as one melissa

Answers

Answer:

11 times the weight of Philip.

Explanation:

From the question given above, the following data were obtained:

Weight of Melissa (i.e cow) = 0.65 tons

Weight of Philip (i.e rabbit) = 192 ounces

Next, we shall express the weight of Philip (i.e the rabbit) in tons. This can be obtained as follow:

1 ounce = 3.125×10¯⁵ ton

Therefore,

192 ounce = 192 ounce × 3.125×10¯⁵ ton / 1 ounce

192 ounce = 0.06 ton

Thus, the weight of Philip (i.e the rabbit) in ton is 0.06 ton.

Next, we shall determine the ratio of the weight of Melissa (i.e the cow) to the weight of Philip (i.e the rabbit). This can be obtained as follow:

Weight of Melissa (i.e cow) = 0.65 ton

Weight of Philip (i.e rabbit) = 0.06 ton

Melissa /Philip = 0.65/0.06

Melissa /Philip = 11

Melissa = 11 × Phillip

Thus, it will take 11 times the weight of Philip to weigh as much as Melissa.

A Bee MysteryRecent surveys around the world have found some very sad and troubling news. Bees are not doing well. According to Time: Science & Space, "an estimated ten million beehives ... have been lost since 2006." What's worse, scientists are not sure why. Most beekeepers will tell you that bees tend to die in large numbers every spring. This is normal and necessary to keep a hive of bees healthy. But when the deaths add up to more than half the bees in an entire country, that is something altogether different and dire. Scientists have called this "colony-collapse disorder" or CCD. This name describes the effect, though, and not the cause of the die-out. Scientists simply do not know what is killing the bees.Many things make it hard for bees. Varroa mites move into a colony and weaken it. Further, these mites carry viruses that attack those that survive. In addition, a new bacterium was recently discovered that attacks bees intestinally and kills them. Beekeepers go to great lengths to protect bees from these invaders, and for many years have been able to control them. All these attackers and the methods used to combat them do stress the bees, however.Many feel the problem is not some new threat, but a decline in the habitat available to bees. Development of grasslands once home to wild flowers and food for bees has been universal. Pavement makes it easy to drive, but it replaces wild grasses and other food sources for bees. Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health. We plowed under a varied habitat and plantedin many casesa single plant like beets. Then we sprayed all kinds of chemicals on the beets to keep other bugs away and in doing so also harmed bees. Now, to treat all the mites and other invaders, bee keepers use additional chemicals to kill the invaders. These chemicals also shorten the life of the bees. Have the use of chemicals, loss of habitat, and invading parasites made life impossible for bees? Experts continue to argue various theories, but few have any answers.Colony collapse disorder is perhaps one of the most mysterious problems modern science has tried to solve. Whether the problem is environmental or an unknown disease, we will all feel the effects if bees continue to decline. Bees affect almost every aspect of the human food chain. From the fruits, vegetables, and grains we eat, to the grasses and grains we feed our livestock, we depend on bees to keep us healthy. According to the Natural Resources Defense Council, bees account for 15 billion dollars in crops. Honey is a treasure for sure, but the real gold is in the strawberries, apples, peaches, and green beans we eat and need to stay healthy ourselves. All told, the outlook for bees is not good. The outlook for humans may not "bee" so good either.Read this sentence from the text:Perhaps, long before the mites and parasites moved in, humans took away enough of the bees' habitat to weaken their health.How does this line function in the text?A.
