D , since Voltage is one joule per coulomb
Answer:
A) G = m³/kg.s²
B) E = kg.m²/s²
Explanation:
A)
The given relation is:
F = Gm₁m₂/r²
where, the units of all variables are:
F = Force = kg.m/s²
m₁ = m₂ = mass = kg
r = distance = m
G = Gravitational Constant = ?
Therefore,
kg.m/s² = G(kg)(kg)/m²
(kg.m/s²)(m²/kg²) = G
<u>G = m³/kg.s²</u>
<u></u>
B)
The given equation is:
E = mc²
where, the units of all variables are:
m = mass = kg
c = speed = m/s
E = Energy = ?
Therefore,
E = (kg)(m/s)²
<u>E = kg.m²/s²</u>
This is the correct answer, which is not present in any option.
Answer:
The initial current, Io = 2.06×10^-4A
Explanation:
The I itial current ,Io of a circuit is given by:
Io = Vo/R
Where Vo = initial votage
R = resistance in ohms
Given:
Vo = 1.50V
R = 7290ohms
Io = 1.50/ 7290
Io = 2.06 ×10^-4A
Cuz Of Newton’s third law, every actions there is an equal and opposite reaction.
