Answer:
<h2>The answer is 67.5 km</h2>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
distance = velocity × time
From the question we have
distance = 90 × 0.75
We have the final answer as
<h3>67.5 km</h3>

The way that scientists ensure that data is reliable Clear Explanation
Answer:
Explanation:
Given
Mass of object (m)=6 kg
falling height(h)=10 m
mass of water()=600 gm
temperature of water =15
specific heat of water
Let T be the Final Temperature of water
Here Object Potential Energy is converted into Heat energy which will be absorbed by water
Potential Energy(P.E.)
Heat supplied
T-16=0.234
This is not an efficient way of heating water as there is onlyincrease in temperature.
