Answer:

262.5Pa

Explanation:

Given parameters:

P1  = 175Pa

T1  = 300K

T2  = 450K

Unknown:

P2  = ?

Solution:

To solve this problem, we are going to use an adaptation of the combined gas law.

           [tex]\frac{P1}{T1}[/tex]    = [tex]\frac{P2}{T2}[/tex]  

  Insert the parameters and solve;

           [tex]\frac{175}{300}[/tex]    = [tex]\frac{P2}{450}[/tex]  

          P2 = 262.5Pa

Answer:

DP = 56 [kg*m/s]

Explanation:

We know that momentum is defined by the product of mass by Velocity. In this way by means of the following equation, we can calculate the impulse.

[tex]P=m*v\\[/tex]

where:

P = momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

Now replacing:

[tex]P=8*9\\P=72[kg*m/s][/tex]

And after the ball hits the wall:

[tex]P_{2}=8*2\\P_{2}=16[kg*m/s][/tex]

The change in momentum is equal to:

[tex]DP=72-16\\DP = 56 [kg*m/s][/tex]

Answer:

Explanation:

Kinetic Energy = 0.5(Mass)(Velocity2)

Kinetic energy= 0.5 × 10kg × (50m/s)2

Kinetic Energy = 5kg × 2500m/s

Kinetic energy = 125000 J ( Ans)

Answer:

The force of gravitational will decreases by a factor of 4

Explanation:

The given parameters are;

The symbol that represents the given mass = m

The mass of the circular ring = M

The initial distance of the mass "m" located at the point P from the center O = h

The final distance of the mass "m" when moved further away from point O = 2·h

Given that h = r, we have;

[tex]The \ initial \ gravitational \ force, F_1 =G \cdot \dfrac{M \cdot m}{r^{2}}[/tex]

Therefore, when OP = 2·h, we have;

OP = 2·r and the new gravitational force, F₂, is given as follows;

[tex]F_2 =G \cdot \dfrac{M \cdot m}{(2\cdot r)^{2}} = G \cdot \dfrac{M \cdot m}{4\cdot r^{2}} = \dfrac{1}{4} \times G \cdot \dfrac{M \cdot m}{r^2} = \dfrac{1}{4} \times F_1[/tex]

[tex]\therefore F_2 = \dfrac{1}{4} \times F_1[/tex]

Therefore, when the mass, m, is removed such that OP = 2h, the value of the gravitational force decreases by a factor of 4.

When an athlete perspires after running

When an athlete perspires after running evaporation occurs and helps to cool the body.

Correct option is A.

When an athlete perspires after running then sweat evaporates and we know that evaporation causes cooling as evaporation requires heat energy. The required heat energy is taken away by the molecules of sweat when they convert from liquid into gas, and this causes cooling on the surface of body. That's why it helps to cool the body.

Answer: 288 m

Answer:

d. Two soccer balls that are touching each other

Explanation:

Let [tex]m_1[/tex] be the mass of a tennis ball, [tex]m_2[/tex] is the mass of a soccer ball.

As the mass of a soccer ball is more than the mass of a tennis ball, so

[tex]m_2 > m_1[/tex]

Let [tex]d_1[/tex] be the distance between the centers of both the balls near each other and [tex]d_2[/tex] be the distance between the centers of both the balls touching each other.

So, [tex]d_2 > d_1[/tex]

The gravitational force, F, between the two objects having masses M and m and separated by distance d is

[tex]F=\frac{GMm}{d^2}[/tex]

Where G is the universal gravitational constant.

As, the gravitational force is directly proportional to the product of both the masses and inversely proportional to the square of the distance between them,  so selecting the larger mass ([tex]m_2[/tex], soccer ball) separated by a lesser distance ([tex]d_2[/tex], touching) to get more gravitational force.

Therefore, there will be a larger gravitational force between them when two soccer balls touching each other.

Hence, option (d) is correct.

Answer:

Two soccer balls that are touching each other

Answer:

P = 5400[W]

Explanation:

We must use the following equation of kinematics to calculate the acceleration.

[tex]v_{f}=v_{o}+a*t[/tex]

where:

Vf = final velocity = 9 [m/s]

Vo = initial velocity = 0 (starting from rest)

a = acceleration [m/s²]

t = time = 1.5 [s]

[tex]9=0+a*1.5\\a=9/1.5\\a=6[m/s^{2} ][/tex]

Now with this second equation of kinematics, we can determine the distance traveled.

[tex]v_{f}^{2}=v_{o}^{2}+2*a*x[/tex]

where:

x= distance [m]

[tex]9^{2} = 0 +2*6*x\\12*x=81\\x=6.75[m][/tex]

Now we must use Newton's second law which tells us that the sum of forces is equal to the product of mass by acceleration.

∑F = m*a

Now replacing:

[tex]F=100*6\\F=600[N][/tex]

Ahora la potencia se puede calcular por medio del producto de la fuerza por velocidad.

[tex]P=F*v[/tex]

where:

P = power [W]

F = force = 600 [N]

v = velocity = 9 [m/s]

[tex]P=9*600\\P=5400[W][/tex]

Explanation:

Answer:

6

Explanation:

Given that :

Resistance (R) = 60 ohms

Required current (I) = 0.15 ampere

Voltage (V) = current (I) * Resistance (R)

V = 0.15 * 60

V = 9v

Number of 1.5V cells required by the device :

9V / 1.5V

= 6

Hence, the device requires six 1.5V cells

1.The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).

2.How does gravity work in space? Gravity is a very important force. Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit.

3.Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon. The moon's gravitation force is determined by the mass and the size of the moon. Since the moon has significantly less mass than the Earth, it will not pull objects toward itself at the strength that Earth will.

Question: Find out more about either one of these forms of energy

Answer:

Solar energy: This is energy generated from the sunlight, and it can be converted to other energy that can be useful. Solar energy from the sun considered a clean source of electricity can be converted to a usable electricity source or stores the light in batteries for thermal use. This energy conversion is possible through the use of solar panels attached to where the conversion would take place so as to capture the light from the sun.

Question: What is being done to make it a more efficient source of energy

Answer:

1. When using solar energy to power homes, it is more efficient to have panels on a green roof because of the characteristics of this roof not to reflect or lose more light from the sun.

2. Improvements on the type of solar cell to use for instance that are cheaper and could maximize the energy from the sun are all ways that make it more efficient.

3. Since solar panels don't produce energy at night, usage of batteries that could store electricity during the day or when the sun is not obscured would make solar more efficient.

Given that,

Initial velocity of the airplane = 66 m/s

Distance = 560 m

Final velocity of the airplane = 0 (stops)

To find,

Acceleration of the airplane.

Solution,

Let us consider that a is the acceleration of the airplane. We can find it using third equation of motion as follows :

[tex]v^2-u^2=2as\\\\a=\dfrac{v^2-u^2}{2s}\\\\a=\dfrac{0^2-66^2}{2(560)}\\\\a=-3.9\ m/s^2[/tex]

Therefore, the acceleration of the airplane is [tex]-3.9\ m/s^2[/tex]

Answer:

Most people when asked, “What is the equation of a line?”, will answer, “y = mx + b”. This is the

equation of a line in what is called slope-intercept form where “m” is the slope and “b” is the yintercept. So, how do you find the equation of a line? There are several different ways that you can find

the equation of a line. I find the equation of a line everytime by following the same three steps:

Step 1: Find the slope of the line.

Step 2: Use the slope to find the y-intercept.

Step 3: Use steps 1 and 2 to write the answer.

I will explain these steps by looking a several examples. Please understand that there are often several

different ways to complete each math problem, but I have found through the years that students are most

successful when the do problems the same way each and every time they attempt the problem. If you

know a different way to find the answer that is great, but I am going to show how to do the problem one

way and use the same technique everytime I see this problem.

Explanation:

The ratio of number of revolution to the radius of the tire will be constant since the distance is constant.  16 - inch radius tire will require 75 revolutions to travel the same distance.

When all points in a body move in concentric circles is known as rotational or circular motion. Below are few facts about circular motion.

Given that the number of revolutions N made by a tire traveling over a fixed distance D varies inversely to the radius r of the tire. That is

N [tex]\alpha[/tex] 1/r

N = K/r

K = Nr

Where K = Proportionality constant

If a 12-inch radius tire makes 100 revolutions to travel a certain distance, Then,

K = 100 x 12

K = 1200 rev inches

How many revolutions would a 16-inch radius tire require to travel the same distance?

by applying the same formula, let us substitute r for 16 inches and 1200 for K

K = Nr

1200 = N x 16

N = 1200/16

N = 75 revolutions

Therefore, 16 - inch radius tire will require 75 revolutions to travel the same distance.

Answer:

P = 53375[W]

Explanation:

First, we must use the following equation of kinematics, which allows us to calculate the acceleration value.

[tex]v_{f}=v_{o}+a*t[/tex]

where:

Vf = final velocity = 34 [m/s]

Vo = initial velocity = 27 [m/s]

a = acceleration [m/s²]

t = time = 6 [s]

Now replacing:

[tex]34=27+a*6\\a=1.167[m/s^{2} ][/tex]

Now we must use Newton's second law, which tells us that the sum of forces is equal to the product of mass by acceleration. In this way, we have the following equation.

ΣF =m*a

where:

F = force [N]

m = mass = 1500 [kg]

a = acceleration = 1.167 [m/s²]

[tex]F=1500*1.167\\F=1750[N][/tex]

Power is defined as the product of force by speed. But we have two speeds, the initial and the final. We must use the average speed to be able to estimate the power needed.

[tex]V_{average}=\frac{34+27}{2} =30.5[m/s][/tex]

And the power:

[tex]P=F*V_{average}\\P=1750*30.5\\P=53375[W][/tex]

Answer:

Their resultant force magnitude on the sleigh is approximately 583.095 N

Explanation:

The given parameters are;

The magnitude and direction in which the two reindeer-in-training pull on the sleigh are;

The force with which Connie pulls on the sleigh, F₁ = 200 N

The direction in which Connie pulls on the sleigh = 60° above the x-axis

The force with which Randolph pulls on the sleigh, F₂ = 800 N

The direction in which Connie pulls on the sleigh = 60° below the x-axis

The vector form of the force with which the two reindeer-in-training pulls the sleigh is given as follows;

[tex]\underset{F_1}{\rightarrow}[/tex] = 200 × cos(60°)·i + 200 × sin(60°)·j = 100·i + (100·√3)·j

[tex]\underset{F_2}{\rightarrow}[/tex] = 800 × cos(60°)·i - 800 × sin(60°)·j = 400·i - (400·√3)·j

The resultant force, R = [tex]\underset{F_1}{\rightarrow}[/tex] + [tex]\underset{F_2}{\rightarrow}[/tex]

∴ R = 100·i + (100·√3)·j + 400·i - (400·√3)·j = 500·i - (300·√3)·j

Their resultant force magnitude on the sleigh, [tex]\left | R \right |[/tex] = √(500² + (-300)²) ≈ 583.095 N

The direction of the resultant force = arctan(-300/500) = arctan(-0.6) ≈ -30.964 which is approximately 30.964° below the x-axis.
