A would be the wavelength, C would be a crest, D would be the amplitude, leaving B which is the trough.
Answer: 15 m/s2
Explanation: I hope this helps or right because I learned this a few months ago
Answer:
W = 19.845 J
Explanation:
Work is defined as W = Fdcos
, where F is the force exerted and d is the distance. Because the direction the ball is falling is the same direction as the force itself, = 0 deg, and since cos(0) = 1, this equation is equivalent to W = Fd. In this case, the force exerted is the weight force, which is equivalent to m * g. Substituting you get:
W = mgd = 0.810 kg * 9.8 m/s^2 * 2.5m
W = 19.845 J
Answer:
Regions near rivers have water surfaces that rapidly change in temperature from cold to hot.
you have your own answer i only selected which is suitable for me . none of them is wrong they re excellent
Answer:
e) Be four times greater
Explanation:
Here we have to use Newton's gravitational law that relates the gravitational force between two objects with their masses (
& 
) and the distance between them (
) in the next way:
(2)
Now if distance between asteroids is halved:
Note that 
because (1) is F so:
It's four times greater!
