What examples can you find in your home that are examples of kinetic and potential energy?

Answers

Answer 1

Answer: Kinetic and potential are not only found in the complicated things but it also appears to be in everyone's everyday lives. Potential energy; the pressure in the unopened soda in your fridge and compressed spring in your mattress. Kinetic energy; rubber band being stretched and when moving your skateboard around your house.

A DUI conviction not only affects the driver involved but also his or her ___________A. friends.
b. family.
c. Both A and B

Answers

Answer: option C

Explanation:

A DUI (driving while under the influence of alcohol or drugs) conviction means that a person has been found guilty, of either DUI or has been found guilty of driving with a 0.8% or more blood alcohol concentration. If a person is found guilty, the DUI conviction will remain on record of driving for 75 years. A DUI conviction not only affects the driver and his/her personal relationships. Conviction can also lead to imprisonment, which will also have a negative effect on family and friends.

Your answer would be both A and B, so c.

A box of groceries requires 5.0 newtons of force to lift it up 1.0 meter. How much work is done?

Answers

Work is defined as the amount of force done multiplied by the distance it was applied. Since it is already given that the object of interest (a box of groceries) was lifted up 1 meter by a force of 5 newtons, work done can be solved using the following formula:

Work = Force * distance
Work = 5 N * 1 meter
Work = 5 N*m = 5 J

A moving 46.6 kg sled feels a 52.9 N friction force. what is the coefficient of friction

Answers

Answer:

The coefficient of friction of the sled is 0.115

Explanation:

It is given that,

Mass of the sled, m = 46.6 kg

Frictional force acting on it, F = 52.9 N

We need to find the coefficient of friction. Frictional force is given by :

$F=\mu mg$

$\mu=(F)/(mg)$

$\mu=(52.9\ N)/(46.6\ kg* 9.8\ m/s^2)$

$\mu = 0.115$

So, the coefficient of friction of the sled is 0.115. Hence, this is the required solution.

An object will remain at rest or maintain constant, straight-line motion unless acted on by a force that is ___________________.A.inertialB.balancedC.unbalancedD.along a straight lineCan someone explain it somehow for me?.

Answers

c) unbalanced . Because if the forces on an object are not balanced, meaning the sum of them is not '0' the object will accelerate to the direction of their sum.

You can see it in the picture. The forces on the object A are balanced meaning their sum is 0 so it will remain at rest or maintain constant. But object B the forces acting on it are not balanced so it will accelerate to the right.

C.unbalanced
Newton's Law explains that an object continues at constant speed due to the net force acting on the object being zero. When the net force is not zero (unbalanced), then there is a net force and the object will accelerate.

If you have a projectile and you double its mass, how would this affect its horizontal velocity?

Answers

Its horizontal velocity is determined at the instant of launch ... the angle and speed with which you launch it.

I suppose its mass might have some influence on how fast and at what angle you launch it, but we'd have to know more about how strong you are, and how you throw, to know what the effect of the mass might be.

But that's still just the effect the mass has on YOUR ability to handle it. If we can assume that you launch every projectile at the same angle and with the same speed, then their different masses have no effect on their range. Every projectile you launch hits the ground at the same place. Mass makes no difference.
