As a positively charged object moves toward a negatively charged object, their potential energy increases. As a positively charg

ed object moves toward another positively charged object, their potential energy increases. As a negatively charged object moves toward another negatively charged object, their potential energy increases. Increasing the distance between two electrically charged objects may raise or lower their potential energy. All of the above are true.

Answer:

As a positively charged object moves toward another positively charged object, their potential energy increases. True

As a negatively charged object moves toward another negatively charged object, their potential energy increases True

Explanation:

When two like charges move towards each other, there is increase in potential energy because the motion is in opposition to the direction if the field. Hence when two negative or two positive charges move towards each other, there is an increase in potential energy.

However, potential energy is inversely related to the distance of separation of the charges.

A flexible shaft consists of a 3 mm diameter steel wire in a flexible hollow tube which imposes a frictional torque of 0.04 N m
Rom4ik [11]

Answer:

2.5m

Explanation:

Torque is defined as the rotational effect of a force on a body.

The torque T for the maximum shear stress is given as 0.1 Nm

Frictional torque is the torque caused by a frictional force

The frictional torque F is given as 0.04 Nm/m

The maximum length of the shaft is thus given as

L = T / F

  = 0.1/0.04

L= 2.5 m

You are driving in a car for 30 minutes, with the windows down and the radio at a high volume. You turn the car off and leave th
matrenka [14]

Answer:

sensory adaption

Explanation:

Sensory adaption is the phenomenon where the intensity of a stimulus experienced by an organism decreases after a certain amount of exposure to the stimulus. This happens in order for us to pay attention to other stimulus.

When you are driving with the windows down and listening to music you are subjected to a lot of stimuli. Here, most of our attention needs to be on driving. So, our brain drowns all the other unneccessary stimuli like the music.

When you enter the car again where the other stimuli which were present while driving are absent, all your attention is diverted to the music. So, your're ears hurt.

A 54 kg man holding a 0.65 kg ball stands on a frozen pond next to a wall. He throws the ball at the wall with a speed of 12.1 m
Inessa [10]

Answer:

The velocity of the man is 0.144 m/s

Explanation:

This is a case of conservation of momentum.

The momentum of the moving ball before it was caught must equal the momentum of the man and the ball after he catches the ball.

Mass of ball = 0.65 kg

Mass of the man = 54 kg

Velocity of the ball = 12.1 m/s

Before collision, momentum of the ball = mass x velocity

= 0.65 x 12.1 = 7.865 kg-m/s

After collision the momentum of the man and ball system is

(0.65 + 54)Vf = 54.65Vf

Where Vf is their final common velocity.

Equating the initial and final momentum,

7.865 = 54.65Vf

Vf = 7.865/54.65 = 0.144 m/s
