F=ma
W=F*distance
375J=(45kg)(a)(5m)
a=375/(45*5)
a=1.67m/s^2
F=ma = 45kg * 1.67m/s^2=75N
Or go straight there like this:
W=F*distance
375J=F(5m)
F=375J/5m
F=75N
Hope this helps. Thanks
The frequency<span> of oscillation of the dot is the </span>frequency<span> #f# of the </span>wave<span>. The second </span>wave<span> has twice the </span>frequency<span> of the first. </span>You<span> can see that the </span>wavelength<span>is halved when the </span>frequency<span> is doubled. Since #v# is constant, </span>if<span> #f# increases, #λ# must decrease, and vice versa</span>
The frequency of a wave with wavelength of 0.050 m and speed of 220 m/s is 4.4 kHz.
<u>Explanation:</u>
Frequency is the measure of repetition of a cycle in a given time. So it is inversely proportional to the wavelength and directly proportional to the speed.
As wavelength is the measure of distance covered by the wave and speed is the rate at which the distance is covered. Frequency will be the number of times a complete cycle will be repeated in that particular time.
Here the wave speed is given as 220 m/s and wavelength is given as 0.050 m.
Then
Thus, the frequency of a wave with wavelength of 0.050 m and speed of 220 m/s is 4.4 kHz.
Answer:
I believe it's the small intestine
Explanation:
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.
