Answer:
The correct option is;
Neither A nor B
Explanation:
The common cause of a vehicle pulling to the right or to the left during braking is due to a contaminated breaking surface or a faulty caliper. Other causes include tire size variation or worn out suspension components.
Other causes include;
Leaking break fluid
Piston frozen in wheel cylinder or caliper
Adjuster of rear break
Tire fault.
As soon as it is observed that the vehicle pulls on one side when braking, the vehicle should should be taking for checks by a qualified mechanic as soon as possible.
Answer:
d. 37 °C
Explanation:
= mass of lump of metal = 250 g
= specific heat of lump of metal = 0.25 cal/g°C
= Initial temperature of lump of metal = 70 °C
= mass of water = 75 g
= specific heat of water = 1 cal/g°C
= Initial temperature of water = 20 °C
= mass of calorimeter = 500 g
= specific heat of calorimeter = 0.10 cal/g°C
= Initial temperature of calorimeter = 20 °C
= Final equilibrium temperature
Using conservation of heat
Heat lost by lump of metal = heat gained by water + heat gained by calorimeter
The statement seems somewhat intuitively satisfying at first. But upon
closer inspection, we must admit that it's too sloppy to be called 'True'.
Self respect and academic integrity compel us to mark it 'False'.
A rocket will accelerate upward as long as the thrust is greater than
the force of gravity AND is directed upward.
Furthermore, imagine a rocket that is falling, buttocks-first, when the
engines ignite and generate a thrust force that is greater than the force
of gravity. Some time will pass before the rocket stops falling and starts
rising.
