-- If the force is applied in the <em>same direction</em> as the object is moving, then the object's momentum in that direction will <em>increase</em>.
-- If the force is applied in the direction <em>OPPOSITE </em>to the way the object is moving, then the object's momentum will <em>decrease</em>.
-- In either case, the CHANGE in the object's momentum will be
(strength of the force) x (length of time the force is applied) .
This quantity is also called "impulse".
Answer:
sun,fire
Explanation:
The main source of heat is sun. It is because there is so much pressure in the core of sun that nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and light.

Answer:
Part A:
Time taken by the snake to reach its top speed is 1.28571 sec.
Part B:
Snake travels 2.0828 m in that time
Part C:
Mongoose have a chance to catch the black mamba
Explanation:
Part A:
According to first equation of motion:
v_f is top speed
v_i is initial or minimum speed
t is time
a is acceleration
Time taken by the snake to reach its top speed is 1.28571 sec
Part B:
According to Second equation of motion:
v_i=0
Snake travels 2.0828 m in that time
Part C:
Distance covered by black mamba is 2.0828 m which is less than its length 3.12 m
2.0828 m<3.12 m
Mongoose have a chance to catch the black mamba
