Electric motors require electricity to move the motor parts and do work (like an electric fan).
Elecgric generators actually burn diesel fuel to spin a motor around and around and around to GENERATE, or MAKE, electricity that you can then use to power your fans and lights in your house.
Answer: magnitude= 2 m/s/s
Explanation: I goes up 2 every second
Answer:
6.7 kg
Explanation:
V = 5000 L = 5000 x 10^-3 m^3 = 5 m^3
T = 0.2 degree C = 273.2 K
P = 1.04 atm = 1.04 x 1.01 x 10^5 Pa = 1.0504 x 10^5 Pa
R = 8.314 in SI system of units
Use the ideal gas equation. Let n be the moles of air occupied in the lungs of whale.
P V = n R T
n = P V / R T
n = (1.0504 x 10^5 x 5) / (8.314 x 273.2) = 231.22
the mass of one mole of air is 28.98 g
So, the mass of 231.22 moles of air = 231.22 x 28.98 = 6700 .88 g = 6.7 kg
It is called condensation. Hope this helped!
