Which of these is formed from lava flows

An airplane is heading due south at a speed of 640 km/h. If a wind begins blowing from the southwest at a speed of 70 km/h (average), calculate the following. (a) the velocity (magnitude and direction) of the plane relative to the ground 643.

A paper clip is made of wire 0.5 mm in diameter. If the original material from which the wire is made is a rod 25 mm in diameter, calculate the longitudinal engineering and true strains that the wire has undergone during processing

As light waves enter the eye, which three structures do they pass through first?

A 2 kg chunk of putty with mass of 2 kg is moving with a velocity of 1 m/s to the east. it collides and sticks to a bowling ball with mass of 5 kg initially at rest. the bowling ball and putty then move with a total momentum of

A 0.5 kg ball is at the top of a ramp which is 8 meters high. How much Vinetic energy does the ball have at the bottom of the ramp? (round the answer to the tenths place)

Explain how wavelength and frequency are important when determining the type of light.

Suppose that you had an electrically charged stick. If you divided the stick in half, each half would have half the original charge. If you split each of these halves, each piece would have a quarter of the original charge.

Technician a says that when measuring a rotor's thickness variation, you should measure the rotor in a minimum of five to eight places around the face of the rotor.

What acceleration will you give to a 25kg box if you push it with a force of 85N

Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. assume that the rate of charge flow in a lightning bolt is about 24000 c/s and this lasts for 105 µs or less.
