You get the net force acting on the object.
Answer:
First one
Explanation:
Maybe because example if a ball that has less mass bounces higher than the one w/more , then a bowling ball should be able with more force.
hope that helped:/
Answer:
Explanation:
Force on q due to Q
= k Qq / ( a² + d²)
x component
= k Qq / ( a² + d²) x d /√ ( a² + d²)
F = kQq d/ ( a² + d²)³/²
differentiating F with respect to d
dF / Dd = kQq [ d. -3/2 ( a² + d²)⁻⁵/² 2d + ( a² + d²)⁻³/²]=0 for maximum F
- 3d² / ( a² + d²) + 1 = 0
a² + d² = 3 d²
a² = 2d²
d = a / √2
Answer:
4
Explanation:
The kilogram-meter per second (kg · m/s or kg · m · s -1 ) is the standard unit of momentum . Reduced to base units in the International System of Units ( SI ), a kilogram-meter per second is the equivalent of a newton-second (N · s), which is the SI unit of impulse .
Answer: Any sound cannot be heard through a glass bell jar because a vacuum is created in the jar and sound cannot travel without a medium like gases, solids or liquids
