Answer:
the star collapses and the outer layers explode as a 'supernova'.
Answer:
![0.495 ms^{-2}](https://tex.z-dn.net/?f=0.495%20ms%5E%7B-2%7D)
Explanation:
According to the newton's second law of motion we can apply F=ma hear
Force = mass * acceleration
(assume the piano is moving left side )
←F = ma
![F_(pull)+ F_(push)= M*a\\77.5 + 48.7 = 255 *a\\a = 0.495 ms^{-2}](https://tex.z-dn.net/?f=F_%28pull%29%2B%20F_%28push%29%3D%20M%2Aa%5C%5C77.5%20%2B%2048.7%20%3D%20255%20%2Aa%5C%5Ca%20%3D%200.495%20ms%5E%7B-2%7D)
The two equal and opposite forces that attract you and the
planet you're on toward each other are caused by gravity.
The force that pulls you toward the planet is what we call
your "weight".
The force that pulls the planet toward you is equal to your
weight. Nobody ever talks about that one.
Explanation:
It is given that,
Length of side of a square, l = 24 cm = 0.24 m
The uniform magnetic field makes an angle of 60° with the plane of the coil.
The magnetic field increases by 6.0 mT every 10 ms. We need to find the magnitude of the emf induced in the coil. The induced emf is given by :
![\epsilon=N\dfrac{d\phi}{dt}](https://tex.z-dn.net/?f=%5Cepsilon%3DN%5Cdfrac%7Bd%5Cphi%7D%7Bdt%7D)
is the rate of change if magnetic flux.
![\phi=BA\ cos\theta](https://tex.z-dn.net/?f=%5Cphi%3DBA%5C%20cos%5Ctheta)
is the angle between the magnetic field and the normal to area vector.
![\theta=90-60=30](https://tex.z-dn.net/?f=%5Ctheta%3D90-60%3D30)
![\epsilon=NA\dfrac{dB}{dt}\times cos30](https://tex.z-dn.net/?f=%5Cepsilon%3DNA%5Cdfrac%7BdB%7D%7Bdt%7D%5Ctimes%20cos30)
![\epsilon=2\times (0.24\ m)^2\times \dfrac{6\ mT}{10\ mT}\times cos(30)](https://tex.z-dn.net/?f=%5Cepsilon%3D2%5Ctimes%20%280.24%5C%20m%29%5E2%5Ctimes%20%5Cdfrac%7B6%5C%20mT%7D%7B10%5C%20mT%7D%5Ctimes%20cos%2830%29)
![\epsilon=0.0598\ T](https://tex.z-dn.net/?f=%5Cepsilon%3D0.0598%5C%20T)
![\epsilon=59.8\ mT](https://tex.z-dn.net/?f=%5Cepsilon%3D59.8%5C%20mT)
or
EMF = 60 mT
So, the magnitude of emf induced in the coil is 60 mT. Hence, this is the required solution.
