<span>You are given a rectangular coil with sides 0.190 m by 0.220 m and has 501 turns of wire, a uniform magnetic field of 0.550 T that is perpendicular to the long axis and a voltage of 115V. The frequency is 780 per second.</span>
The primary reason of gender –
based violence is inequality of power. Second, cultural beliefs, norms and
practices are often used as an excuse to justify the violence experienced. And
thirdly, the idea of inferiority between men and women.
Answer:
Speed of sound is 30.91m/s
Explanation:
Speed is given by:
Speed = distance travelled / time taken
Given:
Distance travelled = 1020m
Time taken = 33seconds
Speed = 1020m/33s
Speed = 30.91m/s
Answer:
ωf =1.78 rev/s
Explanation:
it is a non elastic collision, so conservation of angular momentum is used. and there id no friction
I₁ωi₁ + I₂ωi₂ = (I₁ + I₂)ωf
ωi₁ = 2.0 rev/s*(2π) rad/rev = 4.0π rad/s
assume ωi₂ = 0
Sol the equation to wf
ωf = (½m₁r₁²)ωi₁ / (½m₁r₁² + ½m₂r₂²)
ωf = (m₁r₁²)*ωi₁ / (m₁r₁² + m₂r₂²)
ωf = (5.0kg*(0.18m)²)4.0 π rad/s / ((5.0kg*(0.18m)²) + (3.1*(0.08m)²))
ωf =11.19 rad/s/ 2π
ωf =1.78 rev/s
