In order to answer this, we will set up a simple ratio as such:
1 calorie = 4.184 joules
1 kilocalorie = 1000 calories
1 kilocalorie = 4,184 joules
250 kilocalories = x joules
Cross multiplying the second and third equations, we get:
x joules = 4,184 * 250
250 kilocalories are equivalent to 1,046 kJ
Answer:
The height of the squirrel 
Explanation:
From the question we are told that
The horizontally speed is 
The horizontal distance 
Generally the the time taken is mathematically represented

=> 
=> 
Generally from kinematic equation we have that

Here u is the initial velocity of nut in the vertical and the value is 0 m/s

=> 
6 / 3 = 2
So the reading on the voltmeter will be 2.
