Answer:
C.
Explanation:
If we look at the equation x(final) = v(initial)*t + x(initial), where v(initial in the x dir.) in the same both times, and x(initial) is 0, we can conclude that t is responsible for the change in x(final).
Answer:
<h2>0.094 kg</h2>
Explanation:
Latent heat of vaporization of
at 37°C is
.
When the sweat on our body evaporates, it absorbs energy from our body to overcome it's Latent heat of vaporisation. Thus our body cools down when sweat evaporates.
So, Energy absorbed by sweat to evaporate = Energy lost by body
Specific heat capacity of human body =
. Jogger weights 60.4 kg. Body temperature decreases by 
Energy absorbed from body = 

∴ 0.094 kg of sweat has evaporated from the body.
To solve this problem we will use the concepts related to the speed of a string which is given by the applied voltage and the linear mass density of it. With the speed value we can find the fundamental frequency that will serve as a step to find the maximum speed through the relation of Amplitude and Angular Speed. So:

Where,
T = Tension
= Linear mass density


With this value the fundamental frequency would be



Finally the maximum speed is given with the relation between the Amplitude (A) and the Angular frequency, then




Therefore the correct answer is B.
