Answer:
x = 0.081 m.
Explanation:
a) To find how much does the atmospheric pressure cause the spring to compress we need to use the following equation:
(1)
<u>Where</u>:
F: is the force
k: is the spring constant = 3300 N/m
x: is the distance of compression =?
The force can be found as follows:
<u>Where</u>:
P: is the atmospheric pressure = 101325 Pa
A: is the area of the piston = πr²
r: is the radius = 0.029 m
Now, from equation (1) we can find x:
Therefore, the atmospheric pressure causes the spring to compress 0.081 m.

Oil is a lubricant which helps increase friction. when u spread sand on a place where oil is spilled the sand reduces friction between road and vehicle tire. the vehicle wont skid.
The distance you should cover is: S=150 km
Your average speed is: v=50 km/h
Therefore, to calculate the time you will take to cover this distance, we can use the basic relationship between space, distance and time, and we find:

so, you will take 3 hours.
Answer:
7A
Explanation:
Current I = potential difference V ÷ Resistance R
I = V/R ........1
The overall resistance of parallel resistors is;
1/Rt = 1/R1 + 1/R2 ........2
Given;
V = 10V
R1 = 2 ohms
R2 = 5 ohms
Substituting the values into equation 2, to calculate the overall resistance;
1/Rt = 1/2 + 1/5
1/Rt = 7/10
Rt = 10/7 ohms
From equation 1, we can solve for the total current;
I = V/Rt = 10/(10/7)
I = 7A
The total current I flowing through a system is 7A
