Answer:
I = 0.0674 kg.m²
Explanation:
given,
mass = 13.5 Kg
torsion constant = k = 0.618 N.m
number of cycle = 28
time = 58.1 s
Time of one cycle
we know,
I = 0.0674 kg.m²
the rotational inertia of the object is equal to I = 0.0674 kg.m²
Answer:
the distance from point C to D is 7.75m
Explanation:
Since each light year is approximately 9 trillion kilometres, 4.80 light years is 43.2 trillion kilometres, or 43,200,000,000,000,000 metres
Answer:
The magnitude of charge is 7.15 nC.
Explanation:
Given that,
Electric field = 4.70 N/C
Distance = 3.70 m
We need to calculate the magnitude of charge
Using formula of electric field
Where, k = Boltzmann constant
r = distance
q = charge
E = electric field
Put the value into the formula
Hence, The magnitude of charge is 7.15 nC.
