Answer: A yo-yo in someone's hand
Explanation:
Potential energy is the energy possessed by a body due to virtue of its position. Kinetic energy is the energy possessed by the body due to virtue of its motion.
A swimmer kicking their legs, a car driving on the road, an arrow flying at a target possess kinetic energy because of their motion. A yo-yo in someone's hand possess elastic potential energy.

|Acceleration| = (change in speed) / (time for the change)
Change in speed = (speed at the end) minus (speed at the beginning).
Change in speed = (96 m/s - 32 m/s) = 64 m/s
|Acceleration| = (64 m/s) / (8.0 sec) = 8.0 m/s²
This solution is written in terms of speed and the absolute value
of acceleration. The question gives no information regarding the
direction of motion at any time, so it's not possible to say anything
about velocity, or the direction of acceleration.
B) the distance between the charged particles is decreased.
C) the magnitude of the charge on both the particles is decreased.
D) the magnitude of the charge on one of the particles is decreased.

The force of repulsion between two like-charged particles will increase if the distance between the charged particles is decreased.
What is coulomb's law?
According to Coulomb's law: The magnitude of each of the electric forces with which two point-at-rest charges interact is directly proportional to the product of the magnitude of both charges
And inversely proportional to the square of the distance that separates them and has the direction of the line that joins them.
The formula will be given as:
We can see that the force is inversely proportional to the distance of the two charges.

C. 873°C.
D. 273°C.
Answers
ºC = 600 - 273
ºC = 327ºC
Answer B
hope this helps!
Answer:
327 degrees Celsius
Explanation:
The formula to convert Celsius to Kelvin is:
Degrees Celsius=Kelvin-273
You substitute for the known values and solve.
Degrees C=600 K- 273
Degrees C=327

Let's clean those up first, and then we'll work on the answer.
-- The car is NOT moving with uniform velocity.
'Velocity' includes both speed and direction. If either of these
changes, it's a change of velocity.
On a circular track, the car's direction is CONSTANTLY changing,
so its velocity is too.
The thing that's uniform is its speed, not its velocity.
-- A 'neutron' is a subatomic particle found in the nucleus of most
atoms. It's not a unit of force. The unit of force is the 'Newton'.

OK. A centripetal force of 6,000 newtons keeps 1,200 kg of mass
moving in a circle at 20 m/s.
The formula:
Centripetal force = (mass) (speed)² / (radius)
Multiply each side
by 'radius': (centripetal force) x (radius) = (mass) x (speed)²
Divide each side by
'centripetal force': Radius = (mass) x (speed)² / (centripetal force)
Write in the numbers
that we know: Radius = (1200 kg) (20 m/s)² / (6000 Newtons)
= (1200 kg) (400 m²/s²) / (6000 Newtons)
= (480,000 kg-m²/s²) / (6000 kg-m/s²)
= (480,000 / 6000) meters
= 80 meters .
