Answer and Explanation :
The opposition of the flow of alternating current produced by a magnetic field is called inductive reactance it is denoted by , The value of the inductive reactance depends on the value of inductance. The good thing about inductive reactance is that it is not responsible for the power loss as resistance is responsible for the power loss
Answer:
Explanation:
given,
mass of the body = 40 Kg
speed in x-axis = 238 m/s
mass break into three part
m₁ = 7 kg
v₁ = 356 m/s (along the positive y axis)
m₂ = 4.5 kg
v₂ = 357 m/s(along the negative x axis)
m₃ = 40 - (7 + 4.5) = 28.5 Kg
v₃ = ?
using conservation of momentum
MV = m₁v₁ + m₂v₂ + m₃v₃
Answer:
Explanation:
find solution below
Answer:
The moment of inertia about the rotation axis is 117.45 kg-m²
Explanation:
Given that,
Mass of one child = 16 kg
Mass of second child = 24 kg
Suppose a playground toy has two seats, each 6.1 kg, attached to very light rods of length r = 1.5 m.
We need to calculate the moment of inertia
Using formula of moment of inertia
m = mass of seat
m₁ =mass of one child
m₂ = mass of second child
r = radius of rod
Put the value into the formula
Hence, The moment of inertia about the rotation axis is 117.45 kg-m²
