The natural tendency of an object to remain at rest or in motion with constant velocity is called Inertia.
194.
Which of the following projection angles will result in the greatest range?
Correct Answer: B. 45°
One-liner
The projection angle of 45° results in the greatest range for a projectile launched on level ground (neglecting air resistance).
195.
A wheel with pointed edges like teeth are?
Correct Answer: B. Gear
One-liner

196.
A person can exert maximum pressure on the ground if ?
Correct Answer: A. He stands on the toes of one foot
One-liner
A person exerts maximum pressure on the ground when he stands on the toes of one foot, because pressure is inversely proportional to the surface area in contact with the ground.
197.
The clouds float in atmosphere because of _?
Correct Answer: A. Less Density
One-liner
Clouds float in the atmosphere because of their less density compared to the surrounding air.
198.

199.
A cable breaks if stretched by more than 2 mm. It is cut into two equal parts. By how much can either part be stretched without breaking?
Correct Answer: D. 1 mm
One-liner
Each half can be stretched by 1 mm without breaking, because the elongation is directly proportional to the original length for the same material and cross-section.
200.
