An electron of momentum 400 assuming no recoil, find the momentum transfer and its reduced de broglie wavelength. mev/c is scattered at an angle of 15 deg by a calcium nucleus also calculate the mott differential cross-section (point-like nucleus), and by what factor it is reduced if the calcium nucleus (a-40) can be assumed to be represented buy a model of a sphere with radius a 1.2 a fm (model i in fig. 3 of williams)

Fill in the blank. the number of each type of element in the compound (other than 1) is represented by a small number to the right of the element symbol.

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
