Explanation:
Following are two interactions that are generally involved when we use a TV remote control to change the channel :
1. Figure touches remote buttons, and its a short range interaction.
2. Now remote sends signal to Television, this is a long range interaction.
The final velocity of the rocket is 77.5 m/s in the direction of motion
Explanation:
The given in the problem is:
1. The rocket travels 600 m
2. It starts from rest
3. It is being accelerated uniformly at rate 5 m/s²
We need to find the final velocity
We can use this rule to solve the problem
→ v² = u² + 2 a s
where v is the final velocity, u is the initial velocity, s is the distance
and a is the acceleration
→ u = 0 m/s , a = 5 m/s² , s = 600 m
Substitute these values in the rule above
→ v² = (0)² + 2 (5)(600)
→ v² = 6000
Take √ for both sides
→ v = 77.5 m/s in the direction of motion
The final velocity of the rocket is 77.5 m/s in the direction of motion

Evaporation is the process of the hydrological cycle maintained by the ocean's large surface area.
This is due to water pressure
You're driving along, and you see the light turn red, 1/2 block
in front of you. You gently put on the brakes.
The car loses kinetic energy and slows down.
The brakes absorb the kinetic energy, and they heat up.
______________________________________
If you're, let's say, coming down a mountain or a really long
hill, then the potential energy you had at the top changes to
kinetic energy, little by little, as you come down. Whenever
the speed of the car gets too high, you push the brakes to
slow it down. Then you take your foot off of the brakes, and
let them cool.
If you don't do that, and instead you keep your foot on the brakes
all the time, then the brakes keep getting hotter and hotter, and
by the time you get to the bottom, you have flames shooting out
from the hubcaps and burning the paint off the fenders !
I only saw this happen once, many years ago, when I was in a car
coming down a long road from the top of a mountain in China.
Thank goodness I was not the person who was driving !
I would have been seriously embarrassed.
