A mass M tied to a light string is moving in a vertical circle. The tension in the string at the top is TT and TB at the bottom of the circle. The work done by the tension on M as it moves from bottom to top is:

What is the order of the moon, earth, and sun in a lunar eclipse and a solar eclipse?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 710 n/m. it is initially at rest on an inclined plane that is at an angle of θ = 23° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.19. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. a) what is the block's initial mechanical energy? b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Which statement correctly describes the relationship between frequency and wavelength?
