Answer the following questions
1. a. Draw a graph to show the variation of acceleration due to gravity with
distance from the center of the earth.
b. Define gravitational potential and derive an expression for it.
2. a. Define centripetal force with an example.
b. How much force is required to move a 500 kg car around a circular track
of radius 50m with a velocity of 36km/ hr.
3. A vector can be represented in different ways
a. How is a vector quantity represented graphically and symbolically? 2
b. What does modulus of a vector represent?
c. Find the resultant of two forces, one 6N due east and another 8N due
North.
4. Temperature is the measurement of the degree to which the body is hot or
cold.
a. Which quantity determines the temperature of a body?
b. How is temperature related to the kinetic energy of a body?
c. Define absolute Zero?
d. At what point on the thermometric scale does Kelvin scale reading
coincide with Fahrenheit scale reading?
5. a. What is meant by specific heat capacity of water is is 4200Jkg °C. 1
b. Calculate the amount of heat required to convert 1Kg of ice at-10°C to
steam at 100°C? (Given : specific heat capacity of ice = 500kg* °C',
specific heat capacity of water is 4200kg" C , specific latent heat of ice
=3.36x10 Jkg, latent specific heat of steam= 2.26x10 Jkg")
