Answer:

F' = F/16

Explanation:

The gravitational force between masses is given by :

F=G\dfrac{m_1m_2}{r^2}

If the distance between the center of two objects is quadrupled, r' = 4r

New force will be :

F'=G\dfrac{m_1m_2}{r'^2}\\\\F'=G\dfrac{m_1m_2}{(4r)^2}\\\\F'=\dfrac{Gm_1m_2}{16r^2}\\\\F'=\dfrac{1}{16}\times \dfrac{Gm_1m_2}{r^2}\\\\F'=\dfrac{F}{16}

So, the new force will change by a factor of 16.

You accelerate a 0.43kg football 5m/s2. Calculate the force you applied to the football.
Elza [17]

The force applied on the football is 2.15 Newton.

Given the data in the question;

  • Mass of football; m = 0.43kg
  • Acceleration; a = 5m/s^2

Force applied; F = \ ?

To determine the force applied on the football, we use Newton's laws of motion:

F = m * a

Where m is the mass of the object and a is the acceleration.

We substitute our given values into the equation

F = 0.43kg\ *\ 5m/s^2\\\\F = 2.15kg.m/s^2\\\\F = 2.15N

Therefore, the force applied on the football is 2.15 Newton.

kipiarov [429]

Answer:

Bio psychology

Explanation:

Since, Dr. Wolski does research on the potential relationship between neurotransmitter deficiencies and mood states. His psychological specialty must be biological psychology.

Biological psychology, or bio psychology, is a discipline in which scientific investigation and clinical practice investigates the relation between brain and body. In this area scholars evaluate the biological basis of feelings, impulses and behaviors.

If you speed through a construction zone while workers are present, your fines could be:.
valina [46]

If you speed through a construction zone while workers are present, your fines could be as much as one thousand dollars.

<h3>What is a Fine?</h3>

This is referred to as the amount which is instructed by a court or authority to be paid as a result of it being a penalty for various types of offences. each crime has its specific fine which helps to serve as deterrent for unlawful behavior in the community.

it is always best not to speed when within a construction zone which has workers present in the area. This is ideal as it helps to prevent incidences of accidents or death.

it is therefore the reason why a fine of 1000 dollars is to be paid so that people can think of such high amount before performing certain types of activities when driving and makes it the most appropriate choice.

Explain what it means to view something from a frame of reference. Provide an example that illustrates your explanation. (4 poin
Mumz [18]

A frame of reference is where you or the given object exists in a three-dimensional plane, by which you or it can observe another object in the same three-dimensional plane. 

For example, you are sitting next to the train tracks. Where you are sitting is the frame of reference to which you observe the moving train. 

Now say the train moves at 200mph. 

If you are sitting, from your frame of reference the train is moving at 200mph. 

If you want to get more complicated, the train appears to be coming toward you much slower than 200mph and gradually increasing until it is directly in front of you, which it appears to be moving at 200mph, and as it travels away from your frame of reference it appears to not only be getting smaller but also appears to be slowing down, even though objectively it is not. 

However, now say you are in a car parallel to the train and you are moving at 60 mph. 

Now, from your frame of reference the train moving at 200mph seems to you to only be moving at 140mph - that is, the moving speed minus your speed. 

Here is another example: 

You are standing in an airfield. You look up and see a plane just 50 feet above you. From your frame of reference, the plane appears to be moving very fast. 

You look up again and see a plane high up at 30,000 feet. Even though that plane is moving at the same speed as the first plane, from your frame of reference it appears to be barely moving at all, because it is so far away.

The rotating loop in an AC generator is a square 18 cm on each side. It is rotated at 60.0 Hz in a uniform magnetic field of 0.3
Brums [2.3K]

Answer:

The maximum amplitude power is 1.12 W

Explanation:

Given;

length of each side of the square, L = 18 cm = 0.18 m

angular frequency, f = 60 Hz

magnetic field, B = 0.3 T

resistance of the loop, R = 12 ohm

The area of the loop, A = L² = 0.18 m x 0.18 m = 0.0324 m²

The angular speed, ω = 2πf = 2π x 60 = rad/s = 377.04 rad/s

The maximum value of emf induced;

E_{max} = NBA \omega\\\\where; \\N \ is \ number \ of \ turns\\\\E_{max} = (1) \times 0.3 \times 0.0324 \times 377.04\\\\E_{max} = 3.665 \ V

The maximum amplitude power is calculated as;

Power = \frac{(E_{max})^2 }{R} \\\\Power = \frac{(3.665)^2}{12} \\\\Power = 1.12 \ W
