Answer:

35 mph

Explanation:

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

Time (t) = 2 hours

Distance (d) = 70 miles

Speed (S) =.?

Speed is simply defined as the distance travelled per unit time. Mathematically, it is expressed as:

Speed (S) = Distance (d) / Time (t)

S = d/t

With the above formula, we can calculate how fast (i.e the speed) Joe will need to drive to make it to his Grandma's house on time. This can be obtained as follow:

Time (t) = 2 hours

Distance (d) = 70 miles

Speed (S) =.?

S = d/t

S = 70/2

S = 35 mph

Therefore, Joe will drive at 35 mph in order to get to his Grandma's house on time.

Answer: yes because all densities can be simplifed it just depends on the number.

Answer:

P = W / t       where P is power and W the work done

P = F x / t = F v

Then v = P / F = 450 J/s / 350 N = 1.29 m/s

T = 46.6 m / 1.29 m/s = 36.1 sec      where T is the required time

Answer:

Well, There are a couple reasons it could seem like nobody loves you...

Explanation:

One reason is that people really do love you, they just were never shown love and affection so they are unsure of how to show that to you. Another reason could be that it's god telling you that you are meant for much bigger and greater things. Maybe it's him reminding you that, yeah, people really suck, but that's life, and you're better than that. If you make the right decisions in life, you will be able to stand taller than they ever did. I hope this helps.. : )

Answer:

Motion

Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. If the object was already moving, then it will just keep moving. So, the object can be moving even when there is no force applied to it.

Forces may cause an object to change its state if it is unable to move. The force make the object to move from its state of rest.

Force is an external agent acting on an object to deform it or to change it state of rest or motion. There are various kinds of forces such as gravitational force, nuclear force, magnetic force, frictional force etc.

Force is a vector quantity thus, it is characterised by its magnitude and direction. According to Newton's first law of motion, an object will continue in its state or motion or rest until an external force acts on it.

Therefore, force changes the state of an object. Force is dependant on the mass of the object. Greater the mass, greater will be the force required to move the object from stationary to stop it from motion.

According to second law of motion, force is the product of mass and acceleration of the object. Hence, force accelerates the body and a change in force changes the acceleration of the object.

B. racism and its adverse effects on child development

Explanation:

Dr. Mamie Clark studied the effects of segregation and racism on the self-esteem of black children.

According to Clark in O'Connell & Russo, 2001, p. 271; "To separate them from others of similar age and qualifications solely because of their race generates a feeling of inferiority as to their status in the community that may affect their hearts and minds in a way unlikely ever to be undone...."

One of her works titled "The Development of Consciousness of Self and the Emergence of Racial Identification in Negro Preschool Children" investigated the early level of conscious racial identity in black preschool children.

Answer:

See the answer below

Explanation:

This is because, at 20 °C, the solution has become saturated with the baking soda.

The solubility of a substance is the maximum amount of that substance that will dissolve in a particular solvent at a given temperature. The solubility of a substance generally increases with an increase in temperature.

At 20 °C temperature, the maximum amount of baking soda that can dissolve in a liter of water has been exceeded by Miguel. Hence, no matter how hard he tries to stir the solution, the excess baking soda will not dissolve.

The reason he can’t get all of the baking soda to dissolve is; because at 20 °C, the solution has become saturated with the baking soda.

For us to say a substance is soluble, it means that the maximum amount of that substance will dissolve in a particular solvent at a given temperature. Thus, the solubility of a substance is said increase with a corresponding increase in temperature.

From the question, at 20 °C temperature, miguel has exceeded the maximum amount of baking soda that can dissolve in a liter of water. Therefore, no matter how hard he tries to stir the solution, it will not dissolve due to the excess soda.

Answer:

a vacuum formed above the column of mercury in a mercury barometer.

Answer:

An air-free space above the free surface of a liquid in a vessel that is closed above the liquid

Answer: -49m/s.

Explanation:

As the rock only falls, we will assume that the initial vertical velocity is zero.

We neglect the air friction, so the only force acting on the rock is the gravitational force, this means that the acceleration is -g = -9.8m/s^2.

Then we can write:

a(t) = -9.8m/s^2

To write the velocity of the rock, we must ingrate over time and get:

v(t) = (-9.8m/s^2)*t + v0

where v0 is the initial vertical velocity, and as we said above, v0 = 0m/s

Then the vertical velocity as a function of time is:

v(t) = (-9.8m/s^2)*t

Now, the question is:

"...If a rock falls for 5 seconds near the surface of the earth and with no air friction, it will reach a velocity of..."

Then we need to evaluate the velocity equation in t = 5 seconds.

v(5s) = (-9.8m/s^2)*5s = -49m/s.

The volume of the gasoline needed for the gang to successfully make it to the new destination is 340.02 liters.

"Your question is not complete, it seems to be missing to following information";

the new destination of the gang is 2695 miles

The given parameters;

1 gallon = 3.785 liters

The rate of gasoline consumption in miles per liter is calculated as;

[tex]v = \frac{30 \ miles}{gallon } \times \frac{1 \ gallon}{3.785 \ liters} = 7.926 \ miles/liter[/tex]

The volume of the gasoline needed for the gang to successfully make it to the new destination is calculated as;

[tex]volume \ of \ gasoline = \frac{2695 \ miles}{7.926 \ miles/liter} = 340.02 \ liters[/tex]

Thus, the volume of the gasoline needed for the gang to successfully make it to the new destination is 340.02 liters.

Answer:

The options are not shown, so let's derive the relationship.

For an object that is at a height H above the ground, and is not moving, the potential energy will be:

U = m*g*H

where m is the mass of the object, and g is the gravitational acceleration.

Now, the kinetic energy of an object can be written as:

K = (1/2)*m*v^2

where v is the velocity.

Now, when we drop the object, the potential energy begins to transform into kinetic energy, and by the conservation of the energy, by the moment that H is equal to zero (So the potential energy is zero) all the initial potential energy must now be converted into kinetic energy.

Uinitial = Kfinal.

m*g*H = (1/2)*m*v^2

v^2 = 2*g*H

v = √(2*g*H)

So we expressed the final velocity (the velocity at which the object impacts the ground) in terms of the height, H.

Answer:

Explanation:

In free fall, gravity constantly accelerates an object (increases its velocity)—until it hits terminal velocity. Specifically, gravity increases a falling object's velocity by 9.8 meters per second (m/s) with every passing second. (Whereas velocity is measured in m/s, acceleration is measured in meters per second squared, or m/s2.) How does this constant acceleration affect the distance that an object travels over time? In this experiment you will roll a marble down a ramp to find out.

By adjusting the ramp's height, width, or inclination, you can increase the velocity at which the marble travels down it.

As a tool for lifting or lowering a load, an inclined plane, sometimes referred to as a ramp, is a flat supporting surface that is tilted at an angle from the vertical direction with one end higher than the other.

One of the six traditional simple devices that Renaissance scientists defined is the inclined plane. Heavy weights are transported over vertical obstacles using inclined planes. Examples include a ramp used to load cargo into a truck, a pedestrian ascending a ramp, or an automobile or train ascending an incline.

Less force is needed to push an object up an inclined plane than to lift it straight up, but the distance travelled is greater.
