Answer:48.52 kJ
Explanation:
Given
Resistance
temperature increases from 
Voltage=50 V
Heat given(H)
Where V=voltage applied
t=time
R=Resistance
Heat absorbed by water is
where
m=mass of water
c=specific heat of water
=change in temperature
Therefore 90-41.48=48.52 kJ is not absorbed by water and leaves the system into the surroundings.
Answer:
C
Explanation:
It is the answer I think let me know
- Mass=m=142kg
- Acceleration=a=30m/s
- Force=F
Using Newton's second law
The one that will change the velocity of a periodic wave is :
B. Changing the medium of the wave
Waves is always determined by the properties of the medium, which means that changing the medium will change the velocity of the wave
