What is that?? Please tell us
Answer:
Explanation:
Momentum change for either skater is mΔv = 75.0(5.0) = 375 kg•m/s
As a change in momentum is equal to an impulse
375 = FΔt
F = 375/0.100 = 3750 N
As 3750 N < 4500 N no bones are broken.
Answer:
It will have aim at a point "below" the insect.
From the insect's point of view, the fish will appear to be shallower than it actually is because a ray of light from the insect to the fish will be bent "towards" the normal when the ray enters the water
Well that can ruin the future and mess up your future planned eating routine/ plan not sure how else to say it sorry lol, but it can be worse as you get older since you can suffer from back problems from the weight dragging you down or swollen feet and you can be making your adulthood worse when your actually and adult
Answer:
The induced emf in the coil is 0.522 volts.
Explanation:
Given that,
Radius of the circular loop, r = 9.65 cm
It is placed with its plane perpendicular to a uniform 1.14 T magnetic field.
The radius of the loop starts to shrink at an instantaneous rate of 75.6 cm/s , ![\dfrac{dr}{dt}=-0.756\ m/s](https://tex.z-dn.net/?f=%5Cdfrac%7Bdr%7D%7Bdt%7D%3D-0.756%5C%20m%2Fs)
Due to the shrinking of radius of the loop, an emf induced in it. It is given by :
![\epsilon=\dfrac{-d\phi}{dt}\\\\\epsilon=\dfrac{-d(BA)}{dt}\\\\\epsilon=B\dfrac{-d(\pi r^2)}{dt}\\\\\epsilon=2\pi rB\dfrac{dr}{dt}\\\\\epsilon=2\pi \times 9.65\times 10^{-2}\times 1.14\times 0.756\\\\\epsilon=0.522\ V](https://tex.z-dn.net/?f=%5Cepsilon%3D%5Cdfrac%7B-d%5Cphi%7D%7Bdt%7D%5C%5C%5C%5C%5Cepsilon%3D%5Cdfrac%7B-d%28BA%29%7D%7Bdt%7D%5C%5C%5C%5C%5Cepsilon%3DB%5Cdfrac%7B-d%28%5Cpi%20r%5E2%29%7D%7Bdt%7D%5C%5C%5C%5C%5Cepsilon%3D2%5Cpi%20rB%5Cdfrac%7Bdr%7D%7Bdt%7D%5C%5C%5C%5C%5Cepsilon%3D2%5Cpi%20%5Ctimes%209.65%5Ctimes%2010%5E%7B-2%7D%5Ctimes%201.14%5Ctimes%200.756%5C%5C%5C%5C%5Cepsilon%3D0.522%5C%20V)
So, the induced emf in the coil is 0.522 volts.
