Answer:
d=510.2m
t=10.2s
Explanation:
The formulas for accelerated motion are:

From them we can get
.
We have:

And substitute:

We multiply both sides by 2a, and continue:

Being d the displacement
, we have 
For our exercise, we will write this as:

And taking upwards direction positive and imposing final velocity 0m/s (for maximum height), we have:

For the time we use:

Answer:
8563732.58906 Pa
3992793.23326 Pa
5708.00923 J
Explanation:
V = Volume
N = Number of molecules = 
T = Temperature = 300 K
b = 
= Boltzmann constant = 
P = Pressure
We have the equation

The pressure is 8563732.58906 Pa
For isothermal expansion

The pressure is 3992793.23326 Pa
Work done is given by

The work done is 5708.00923 J
Answer:
Stationary
20N
Explanation:
From the graph, we see that the body traveling is on a fixed position. Therefore, it is a stationary body.
The graph given is a position - time curve.
This curve depict a body changing position with given time.
Since the line of the curve is on a single position, the body is not changing position with the passage of time therefore, it is a stationary object.
B. 20N
From Newton's third law of motion we understand that "action and reaction force are equal but oppositely directed".
Since the person is exerting a force of 20N on the balance.
So, the reaction force by the balance is 20N upward.
