How much internal energy is generated when a 20.0 g lead bullet, travelling at 7.00*10^2 m/s, comes to a stop as it strikes a metal plate

The internal energy generated  = 4900 J

Explanation:

Energy: Energy can be defined as the ability or the capacity to perform work. The S.I unit of Energy is Joules (J)

From the law of conservation of energy, the kinetic energy of the travelling bullet is converted to other forms of energy when it strike the metal plate.

E = 1/2mv² Equation 1

Given: m= 20 g = (20/100) kg = 0.02 kg, v = 7.00 × 10² m/s = 700 m/s

Substituting these values into equation 1

E = 1/2(0.02)(700)²

E = 0.01(490000)

E = 4900 J

Therefore, The internal energy generated  = 4900 J

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
