The Beams And Joints That Hold It .
Work done = fore × distance
wd= 47N ×o.25m
wd= 12.22Nm
Answer:
8.0 N
Explanation:
Force: This can be defined as the mass of a body and its acceleration. The S.I unit of Force is Newton (N).
Mathematically, Fore is expressed as
F = ma ........................... equation 1
Where F = force, m = mass, a = acceleration.
and
I = mΔv
Δv = I/m ............................ Equation 2
Where I = impulse, m = mass, Δv = change in velocity
Given: I = 6.0 Newton-seconds, m = 0.1 kilogram.
Substituting into equation 2
Δv = 6.0/0.1
Δv = 60 m/s.
But
a = Δv/t
where t = time = 0.75 seconds.
a = 60/0.75
a = 80 m/s²
Substitute the values of a and m into equation 1.
F = 0.1(80)
F = 8.0 N.
Thus the average force produced = 8.0 N
Answer:
The capacitance is 90 pF.
Explanation:
Given that,
Distance between the plates= 1.50 mm
Charge on each plate = 0.0180μC
Potential difference = 200 V
Suppose we find the capacitance
We need to calculate the capacitance
Using formula of capacitance
Where, Q = charge
C = capacitance
V = potential
Put the value into the formula
Hence, The capacitance is 90 pF.
