Two thermometers, calibrated in celsius and fahrenheit respectively, are put into a liquid. the reading on the fahrenheit scale is four times the reading on the celsius scale. the temperature of the liquid is:
Velocity = displacement / time
First, Always make sure that your units for things are the same. In this question, we are given time in seconds and hours. So, we need to make them all use 1 unit.
I will do seconds.
To convert 80km/h to m/s, divide by 3.6.
22.2222…. m/s = displacement / 2.1s
Multiply by 2.1s on both sides
46.6666……m = displacement
You travelled 47 meters.
The ball at the top of the ramp has potential energy but when it rolls down or when it is rolling down it has kinetic. The ball has kinetic energy when it is moving or rolling down the ramp but there is Potential energy when the ball is at the top or is sitting at the bottom still. when the ball is rolling down the ramp it has heat energy because of how it get speed and it starts to heat up.
Answer:
The coin travels 1.8348 meters above its point of release.
Explanation:
Initial speed = 6 m/s (Assumed vertical speed as not stated in question)
Final Speed = 0 m/s (at the highest point in air)
Acceleration due to gravity = -9.81 m/s^2
Equation of motion used:


s = 1.8348 m
Thus, the coin will travel 1.8348 meters up to its highest point in the air.
