Puffy cumulus clouds, which are made of water droplets, occur at lower altitudes in the atmosphere. Wispy cirrus clouds, which are made of ice crystals, occur only at higher altitudes. On a typical day and at altitudes less than 11 , the temperature at an altitude is given by , where = 16.5 and .

Near the earth , the intensity of radiation from the sun is 1350 W/m2 what volume of space in this region contains 1.0 J of energy?

A mirror with focal length 20 cm , has 4 cm tall object, placed 100 cm in front of it. what is the position of the image? how many cm in front or behind the mirror?

In consideration of conservative and non-conservative forces, If a skier skies down a slope, will the calculation for the speed of the skier at the bottom of the slope be based on conservative or non-conservative forces ? What forces and energy values need to be considered ?

A 5.00-g bullet moving with an initial speed of v0 = 365 m/s is fired into and passes through a 1.00-kg block, as in the figure below. The block, initially at rest on a frictionless horizontal surface, is connected to a spring with a spring constant of 870 N/m.

A rock is dropped from a bridge 300 meters about the New River. Express the height of the rock as a function of time and find the amount of time it takes for it to hit the water.
