The resistance between A and B is 10 ohms.
Well, it goes 60 miles in one hour......so set up a ratio.....
60 miles/5 miles = 1 hr/x.....you'll get 60x = 5....then 5/60 would be 0.083
4. bc it is softer--made of a different material-- has a weaker reaction force
5. the sand would not leave footprints and would rather act as a whole
6. there is no gravity in outer space-- she can just float back to the spaceship no problem!
Wavelength = wavespeed / frequency
0.5 meter = speed / 200 Hz
speed = 0.5m * 200 Hz
= 100 m/s
Solved
Answer:
Explanation:
Given
coefficient of kinetic friction
=0.34
inclination 
weight of block=51 N
(a) When block is moving upward friction force acts downward
thus

as block is moving with constant velocity thus
is zero



(b)When Block slides down the wall friction changes its direction to oppose the block
