Answer:
D) accelerate but will not spin.
Explanation:
On the off chance that there is no air resistance the object will accelerate yet won't turn, this is on the grounds that without air resistance same force is applied on each bit of the object. Force on each segment is coordinated descending i.e parallel force. So there is no force to deliver spin movement in it.
It will accelerate because of gravity
Answer:
The length is 
and the angle is 
Explanation:
The period 
of the pendulum is related to its length 
by
where 
is the acceleration due to gravity.
Solving for we get
putting in 
and we get:
There are two forces acting on the pendulum: The gravitational force 
and the 
student's force. Therefore, the angular displacement 
that these forces give is
putting in 
, 
, and we get
Answer:
Ludwig Boltzmann was an Austrian Physicist and he performed a simple but powerful experiment to gather evidence concerning the velocity distribution of a sample of gas particles.
His experiment revealed that the way Gases are distributed in its normal form across a range of temperature is dependent on the molar mass amen temperature of the gas. Gases with high temperature move faster due to the high number of colliding particles when compared to those with low temperature. Gases with lower molar mass move faster than those with higher molar mass.
Answer:
v = 8.65 m/s
Explanation:
Given that,
Distance covered by the doge, d = 45 m
Time taken, t = 5.2 s
We need to find its average speed. The total distance covered divided by the total time taken is called the average speed of an object. So,
So, the average speed is 8.65 m/s.
