Answer:
Option A is correct.
(The faster object encounters more resistance)
Explanation:
Option A is correct. (The faster object encounters more resistance)
Air resistance depends on various factors:
- Speed of the object
- Cross-sectional area of the object
- Shape of the object
Formula:

As the speed of the object increases the amount of Air resistance/drag increases on the object, as the above formula shows direct relation between Air resistance/drag and velocity i.e F ∝ v^2.

A switch that automatically interrupts or shuts off an electric current at the first indication of a overload
Answer:
1.241/s
Explanation:
From this question, we have the following information:
Mass of oscillator = 310
The time Period, t = 0.180
Decrease = 20 %
Amplitude of oscillation has the formula
A = Aoe^yt
1-20% = 80%
= 0.80
Y x 0.18 = -ln(0.8)
= 0.18Y = 0.2234
Y = 0.2233/0.18
Y = 1.241/s
The damping constant y is Therefore equal to 1.241s
Answer:

Explanation:
When an object strikes the ground, the potential energy of the rock gets converted to the kinetic energy.
A rock is dropped from a distance
above the surface of the earth and is observed to have kinetic energy
when it hits the ground.
For another rock, It is dropped from twice the height
above the earth’s surface and has kinetic energy
when it hits.
For the first rock,
..............(1)
For the second rock,
..............(2)
Dividing equation (2) by (1) we get :

Hence, this is the required solution.
This means that jupiter gravity pull is 3 times stronger than the earth
