10 m/s in 10
3. a car accelerates from 0 m/s to 50 m/s in 10 seconds. what is the acceleration?

5ms⁻²

Explanation:

Given that,

Initial velocity of car (at t=0) u=0 m/s

Final velocity of car (after 10 sec) v=50 m/s

Time taken (t)= 10 sec.

acceleration(a)=?

now,

v = u + at

at = v-u

a=  (v-u) / t

a= (50-0) / 10

a = (50/10)

a=5 ms⁻²

It is necessary to correct the heat capacity of the calorimeter as it is important in the calculations of the heat gained or absorbed the calorimeter. Every parameter is important like the heat capacity of the objects like metals used at a specific temperature as well as the calibration of the temperature device or sensor to measure the temperature changes.
