Answer:
20n
Explanation:
60n - 40n = efficiency of pulley system
20n = efficiency of pulley system
Answer:
198.9 x 10^-16
Explanation:
E = hc/ wavelength
E =(6.63 x 10^-34 x 3 x 10^8)/(0.01 x 10^-9)
E = 198.9 x 10^-16
I believe it is B! Also I am just typing this stuff because it needs to be 20 characters long for some reason! Hope this helps!
Answer:
Part a)
V = 15 Volts
Part b)
P = 180 Watt
Part c)
Rate = 720 Watt
Explanation:
Part a)
When battery is in charging then the potential difference of the terminals of cell is given by
here we know that
EMF = 12 volts
i = 60 A
r = 0.050 ohm
now we have
Part b)
Rate of thermal energy dissipated is the energy which is dissipating across the resistor
so here we have
P = 180 Watt
Part c)
Rate at which Energy stored inside the cell is the rate of electrical energy that is converted into the chemical energy
It would be the first one and the third one
