Abaseball is thrown straight upward on the moon with an initial speed of 35 m/s.
compute:
(a) the maximum height reached by the ball. > (b) the time taken to reach that height.
--> (c) its velocity 30 s after it is thrown.
(d) when the ball's height is 100 m.

Why do electron microscopes have higher resolving power than light microscopes?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.
