Suppose that two objects attract each other with a gravitational force of 16 units. If the mass of both objects was doubled, and if the distance between the objects was doubled, then what would be the new force of attraction between the two objects?

Answers

Answer 1

Answer:

Distance, such that displacement over time is taken into account doesn't change regardless of the length in x meters or mass in kg So the force will remain constant given 16 units
Answer 2

The new force of attraction between the two objects will be remain the same.

What is the gravitational law?

The gravitational law states that the gravitation force is the ratio of the product of the masses and the square of the distance between them.

Let the masses be m and M and the distance between them is r. Then the force is given as,

F = GmM / r²

Suppose that two objects attract each other with a gravitational force of 16 units.

F = 16

GmM / r² = 16 units

If the mass of both objects was doubled, and if the distance between the objects was doubled. Then we have

F' = G(2m)*(2M) / (2r)²

F' = 4GmM / 4r²

F' = GmM / r²

F' = 16 units

The new force of attraction between the two objects will be remain the same.

4 A magnet can exert a force of attraction or a force of repulsion on another magnet.
Which of these forces is a push and which is a pull?

please explain too thanks!​

Answers

Answer:

Push -repulsion

Pull - attraction

Explanation:

When two magnets are brought together, a push happens when a force of repulsion is experienced where the magnets move away from each other. This means their polarity is the same and this will cause the magnet to push away from each other.

When two magnets are brought together , a pull happens when a force of attraction is experienced where the magnets move close to each other. This means their polarity is different and thus causes the magnets to pull closer to each other.

The force causes the car to move at a constant speed of 3 m/s. What will happen if the force is changed to 35 N?

Answers

The question is incomplete, the complete question is;

A car is moving  at a constant speed of 3 m/s when a force of 25N is acting on it. What will happen if the force is changed to 35N?

The car will move at a constant speed of 13 m/s

The speed of the car will not change.

The speed of the car will increase.

The speed of the car will decrease to 1 m/s

Answer:

The speed of the car will increase.

Explanation:

When a the force acting on an object moving at constant velocity is changed, its velocity changes accordingly.

The question said that the car was moving at a constant velocity of 3m/s when a 25 N force is applied, then the car must move faster than 3 m/s when a 35 N force is applied since the 35N force is greater than the 25 N force.

C. An image is created based on the amount of time it takes for a sound wave to return.

D. Tissues in the baby's body reflect high-frequency sound waves.​

Answers

Answer:

C,D

Explanation:

an image is created based on the amont of time it takes for a sound wave to return

Tissues in the babys body reflect high-frequency sound waves

In ultrasound scanning, an image of internal organs is created based on the amount of time it takes for a sound wave to return.Thus, option C is correct.

What is ultrasound scanning?

High-frequency sound waves are used in ultrasound imaging, also known as sonography, to view within the body. Real-time ultrasound imaging allows for the display of blood flowing via blood vessels as well as movement of the body's internal organs.

Contrary to X-ray imaging, ultrasonic imaging does not expose patients to ionizing radiation.A transducer (probe) is positioned either on the skin or inside a bodily orifice during an ultrasonic examination.

To allow the ultrasonic waves from the transducer to pass through the gel and into the body, a small coating of gel is placed to the skin.

For Valentine’s Day, Sally received a helium-filled balloon at a party. On returning home she accidentally left the balloon in the car. Later she went to get the balloon and found it was partially deflated. After being in the house for an hour she noticed it was fully inflated again. Explain why this happened.

Answers

Answer:

If the temperature of the air in the balloon is less than the temperature of the air surrounding the balloon then the balloon will appear slightly deflated because of the difference in temperature.

As the temperature of the air in the balloon reaches the surrounding air temperature, then the balloon will appear to be fully inflated because the temperature of the air in the balloon is the same as the surrounding air temperature.

a person brings his face close to a mirror . h e finds that the image of his face is magnified write the name of the mirror used with reason​

Answers

Answer:

Spherical concave mirrors

Explanation:

Like spherical convex mirrors, spherical concave mirrors have a focus. If the object is closer to the mirror than the focal point is, the image will be virtual, like we talked about before for the plane mirror and the convex mirror.

Concave mirrors, on the other hand, can have real images. If the object is further away from the mirror than the focal point, the image will be upside-down and real---meaning that the image appears on the same side of the mirror as the object.

The closer the object comes to the focal point (without passing it), the bigger the image will be.

You can try this yourself by looking into the concave side of a shiny spoon. If you look into the spoon while holding it at arm’s length, you’ll see an extremely magnified, upside-down image of your face. But as you bring the spoon closer to your eyes, the image will get bigger and bigger.

Explanation:

Given the following

Distance S = 70.6m

Time t = 0.32secs

Initial velocity = 0m/s

Required

Acceleration

Using the equation of motion

S = ut+1/2at²

Substitute

70.6 = 0+1/2a(0.32)²

70.6 = 0.0512a

a = 70.6/0.0512

a = 1,378.9

Hence the acceleration is 1,378.9ms²

The temperature is directly proportional to the speed of sound. Why?

Answers

First, we need to understand what we mean by sound and temperature. Sound is the vibration of particles traveling as a wave. Temperature is a measure of energy in a system of particles. A higher temperature means the particles have a higher energy, higher energy means they're moving around faster, and that faster motion makes them more capable of carrying sound waves.

Ocean waves are hitting a beach at a rate of 3.2 Hz. What is the period of the waves? (2 decimal places)

Answers

Answer:

0.31s

Explanation:

Given parameters:

Frequency of the ocean waves  = 3.2Hz

Unknown:

Period of the waves  = ?

Solution:

The period of a wave is the inverse of the frequency of a wave;

       Period  = [tex]\frac{1}{Frequency}[/tex]

Now insert the parameters and solve;

       Period  = [tex]\frac{1}{3.2}[/tex]   = 0.31s

The period of the wave is 0.31 s.

The question above can be solved using the relationship between period and frequency (T = 1/F).

Frequency: This can be defined as the number of complete oscillations performed by a wave in one second.

Period: This is the time required by a wave to complete one oscillation.

The relationship between period and frequency

Formula:

T = 1/F....................... Equation 1

Where:

T = Period of the waveF = Frequency of the wave

From the question,

Given:

F = 3.2 Hz

Substitute this value into equation 1

T = 1/3.2T = 0.3125 sT = 0.31 s

Hence, the period of the wave is 0.31 s.

A 2 kg rock is at the edge of a cliff 20 meters above a lake The rock becomes loose and falls toward the water below. Calculate its potential and kenetic energy when its at the top and when its halfway down. Its speed is14 m/s at the halfway point

Answers

Answer:

The potential energy (P.E) at the top is 392 J

The kinetic energy (K.E) at the top is 0 J

The potential energy (P.E) at the halfway point is 196 J.

The kinetic energy (K.E) at the halfway point is 196 J.

Explanation:

Given;

mass of the rock, m = 2 kg

height of the cliff, h = 20 m

speed of the rock at the halfway point, v = 14 m/s

The potential energy (P.E) and kinetic energy (K.E) when its at the top;

P.E = mgh

P.E = (2)(9.8)(20)

P.E= 392 J

K.E = ¹/₂mv²

where;

v is velocity of the rock at the top of the cliff = 0

K.E = ¹/₂(2)(0)²

K.E = 0

The potential energy (P.E) and kinetic energy (K.E) at the halfway point;

P.E = mg(¹/₂h)

P.E = (2)(9.8)(¹/₂ x 20)

P.E = 196 J

K.E = ¹/₂mv²

where;

v is velocity of the rock at the halfway point = 14 m/s

K.E = ¹/₂(2)(14)²

K.E = 196 J.

The potential energy (P.E) at the top is 392 J

The kinetic energy (K.E) at the top is 0 J

The potential energy (P.E) at the halfway point is 196 J.

The kinetic energy (K.E) at the halfway point is 196 J.

Calculation of the potential energy and kinetic energy:

Since

mass of the rock, m = 2 kg

height of the cliff, h = 20 m

speed of the rock at the halfway point, v = 14 m/s

We know that

P.E = mgh

P.E = (2)(9.8)(20)

P.E= 392 J

Now

K.E = ¹/₂mv²

here.

v is velocity of the rock = 0

K.E = ¹/₂(2)(0)²

K.E = 0

Now

The potential energy (P.E) and kinetic energy (K.E) at the halfway point;

P.E = mg(¹/₂h)

P.E = (2)(9.8)(¹/₂ x 20)

P.E = 196 J

K.E = ¹/₂mv²

Here,

v is the velocity of the rock= 14 m/s

K.E = ¹/₂(2)(14)²

K.E = 196 J.
