Gauss law states that the electric flux through any closed
surface is proportional to the net electric charge inside the surface. This is
expressed mathematically in the form of:
Φ = Q / εo
Where,
Φ = the electric flux = unknown (which we have to find for)
Q = the net electric charge = 5.0 µC = 5 E-6 C
εo = the permittivity of free space = a constant value =
8.85 E-12 C^2 / N m^2
Plugging in the values
into the equation will result in:
Φ = 5 E-6
C / (8.85 E-12 C^2 / N m^2)
Φ = 564,971.75 Wb = <span>5.6 x
10^5 Wb </span>
Answer:
An object’s weight is proportional to its mass.
<u>Answer</u>
D. 1,500 m/s
<u>Explanation</u>
the wave equation states that,
V = λf
Where V ⇒ Velocity
λ ⇒ wavelength
f ⇒ Frequency
F = 1/T
Where T ⇒ period
F = 1/0.006
= 166.667
∴ V = 9 × 166.667
= 1,500 m/s
Work done = M x g x h
M = Mass of the body in Kg
g = Acceleration due to gravity
h - height of displacement
Work done = (M x g) x h
= 50 N x 1.5 m
= 75 J
Answer:
The kinetic energy of tennis ball is higher than that of baseball.
Explanation:
mass of baseball 
= 0.14 kg
velocity of baseball 
= 41 m/s
mass of tennis ball 
= 0.058 kg
velocity of tennis ball 
= 67 m/s
To find: the kinetic energy of baseball 
and tennis ball 
We know that the kinetic energy is given by the equation,
KE = 
the kinetic energy of baseball = 
= 
= 117.67 J
the kinetic energy of tennis ball = 
= 
= 130.181 J
Hence > , the kinetic energy of tennis ball is higher than that of baseball
