A wave has a frequency of 10 Hz and a wavelength of 4 m. If the frequency is doubled, what will be its new wavelength? Assume the velocity
is constant at 40 m/s.

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
