The bob (weight) at the end of a pendulum has a mass of 0.3 kilograms. the bob is pulled to position b and allowed to swing. it goes all the way to position c and swings back. the potential energy of the bob at position b is joules. if the maximum height of the bob is 0.45 meters when it swings back, joules of energy was transformed to thermal energy. use g = 9.8 m/s2 and pe = m × g × h.

Avalue that describes how heavy an object is and is related to the force of gravity is

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
