Answer:
Mass, m = 105.58 g
Explanation:
We have,
Heat required in aluminium to change the temperature from 68°C to 110°C. It is required to find the mass of aluminium.
Concept used : Specific heat capacity
Solution,
The heat required to raise the temperature is given by :
c is specific heat capacity, for Aluminium, c = 0.902 J/g-°C
So, the mass of aluminium is 105.58 grams.
Answer:
99 joules.
Explanation:
Let m denotes mass of the object and v denotes velocity.
If mass has units of kilograms and the velocity has units of meters per second then the kinetic energy has units of joules.
Kinetic energy is an energy possessed by a body in motion.
Mass (m) = 99 kg
Velocity (v) = 2 m/s
To find kinetic energy, use the following formula:
Kinetic energy = joules
