Answer:
306J
Explanation:
The formula for kinetic energy is given as ½mv².
Using this, we get our answer by substituting the values into the formula.
½ × 0.145kg × 65m/s
= 306.31J
can be rounded off to 306J
Answer:
13
Explanation:
13.0120481928 it is the distance
You're saying that it is the same thing to add or subtract B. This means that B must be the zero vector.
This works with numbers as well, if you feel more familiar to think it this way: in general, if you add something to a number you make it bigger, whereas if you subtract it, you make it smaller.
The only way to cause adding and subtracting to be the same thing is to add or subtract zero: in both cases, you're doing nothing.
Answer:
I think theres air that flows thru it
Explanation:
The wavelength of the wave is 23.55 rad/s.
What is a wavelength simple definition?
Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
Distance b/w one crest and one trough is λ/2 and b/w two crests or two trough it is λ.
Therefore from 2nd crest to 6th trough the total distance
= 4 λ + λ /2 => 9 λ/2
that is given as:
9 λ/2 = 24 cm
λ= 16/3 cm
V = w/k => w × λ /2pi => w = 2 × 3.14 × 20 × 3/16 => 23.55 rad/s
