Answer:
0.0757 kg
Explanation:
m = mass of the body = 95 kg = 95000 g
ΔT = change in the temperature of the body = 0.45 °C
c = specific heat capacity of the body = 4.0 J/(g °C)
M = mass of water evaporated
L = latent heat of vaporization of water = 2260 J/g
Using conservation of heat
Heat gained by water = heat lost by body
ML = m c ΔT
M (2260) = (95000) (4.0) (0.45)
M = 75.7 g
M = 0.0757 kg
This is false. Current is the speed of the charge, 1 amp of current is 1 coulomb per second. So you can imagine the current of a circuit as the current of a river. In a parallel circuit, the river breaks into two separate streams. Some of the water goes down one river, some goes down the other. However, the total amount of water/coulombs never changes. This means that some of the total current will go down one river, and one the other. However, with less coulombs now the current will decrease.
Long story short, since there are two paths, the charge will split and depending on the resistance of each parallel stream a different amount of charge will go down each branch.
Use the kinematic equation: Vf=Vi+at
Then plug;
Vi=14 m/s
a=5 m/s²
t=20 s. Therefore;
Vf=14+(5*20)
Vf=114 m/s.
327,360 feet
most aviation experts agree that the point where space begins is approximately 62 miles up. (62x5280=327,360).
Answer:
By the use of slow motion camera.
Explanation:
Visually, it is very hard to differentiate between an ac and dc power supply. But Since, we that In Ac supply polarity changes 100 times in a second ( because frequency of ac supply is 50 Hz generally). Whereas, Dc gives a steady power supply. So, in slow motion camera we can easily capture the flickering light tubes which won't happen in case of dc supply.
