Answer: The total resistance increases, so the current in the circuit decreases.
A because it depends if the athlete is doing an intense workout he/she would need a sports drink to hydrate them selves
Answer:
The value is 
Explanation:
From the question we are told that
The time taken as seen by aliens 
The time taken as seen by attendant 
Generally from the dilation of time equation we have that

Here c is the speed of light
v is the speed of the alien ship
=>
=> ![1 - \frac{v^2}{c^2} = [\frac{T_1}{T}] ^2](https://tex.z-dn.net/?f=1%20-%20%5Cfrac%7Bv%5E2%7D%7Bc%5E2%7D%20%20%3D%20%20%5B%5Cfrac%7BT_1%7D%7BT%7D%5D%20%5E2)
=> ![1 - \frac{v^2}{c^2} = [\frac{4.1}{8}]^2](https://tex.z-dn.net/?f=1%20-%20%5Cfrac%7Bv%5E2%7D%7Bc%5E2%7D%20%20%3D%20%20%5B%5Cfrac%7B4.1%7D%7B8%7D%5D%5E2)

Given :
Mass =5kg
T

=20
∘
C,T
2
=100
∘
C
ΔT=100−20=80
∘
C
Q=m×C×ΔT
where C= specific heat capacity of water
=4200J/(kgK)
Q=5×4200×80
=1680000 Joule.
=1680KJ
I believe its B. it contains only the colors of the rainbow and TV waves
Hope it helped
