Answer:
The total electric flux through the shell = 34804 N.m²/C
Explanation:
φ = E.A ........................... Equation 1
Where φ = total electric flux through the shell, E = Electric Field, A = surface Area of the sphere
But,
A = 4πr² ................................... Equation 2
Where r = radius of the sphere.
Given: r = 1.4 m,
constant: π = 3.143
Substituting these values into equation 2,
A = 3.143(1.4)²
A = 6.16 m²
Also Given: E = 5650 N/C,
Substituting into equation 1,
φ = 5650(6.16)
φ = 34804 N.m²/C
Thus the total electric flux through the shell = 34804 N.m²/C
<span>When T = room temperature
L = 1.0000m+2.4×10^-5m/°C*0°C = 1.0000m+0=1.0000m
change in the length = l2-l1 = (1.0000m+2.4×10^-5m/°C*T2)-(1.0000m+2.4×10^-5m/°C*T1) = 1.0000m+2.4×10^-5m/°CT2-1.0000m-2.4×10^-5m/°CT1=2.4×10^-5m/°CT2-2.4×10^-5m/°CT1=2.4×10^-5m/°C(T2-T1)
So we don’t need at all the 1.0000m data, we just need T2-T1, which is the difference between room temperature and the current temperature, which is 13.6°C.
change in the length = 2.4×10^-5m/°C*13.6°C = 3.264*10^-4m = 0.3264 mm = 326.4 micrometers</span>

Answer:
<u>Example of Newton's III law</u>
- In the, golf the ball was hit by a club with certain force. As the club hits the ball it's the action. When the ball flies away its the reaction.
- When a person swings a golf club at the ball, when it hits the ball, it causes the ball to roll up the face of the club and into the air towards the target.
