Answer:
B = 0.15 T
Explanation:
To find the magnitude of the magnetic field you use the following formula:
( 1 )
m: mass of the electron = 9.1*10^-31 kg
v: velocity of the electron = 3*10^6 m/s
q: charge = 1.6*10^-19
r: radius = 0.11mm = 0.11*10^-3 m
You replace the values of the parameters in the equation (1).
the magnetic field has a magnitude of 0.15 T
Answer:
B transferred.
Explanation:
The kinetic energy is simply transferred by transforming it into other forms of energy.
According to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
- The moving baseball posses kinetic energy
- As it hits the bat, it is converted to mechanical and thermal energy.
- The bat warms up due to the transfer of the kinetic energy.
- The mechanical energy of the bat cause work to be done on it and it breaks apart.
- This ensures that the energy in this process is conserved.
The answer is *drum roll* tides
