Answer:
112.5 watts
Explanation:
The output voltage (V) = 15 volts
The equivalent resistance for the speakers connected in parallel () is gotten by using the formula:
The current flowing through the amplifier (I) is:
I = V / = 15 / 2 = 7.5 A
The audio power (P) when outputting this maximum voltage is given by:
P = V² / = I²
. Therefore:
P = V² / = 15² /
= 112.5 watts
Answer:
mechanical power used to overcome frictional effects in piping is 2.37 hp
Explanation:
given data
efficient pump = 80%
power input = 20 hp
rate = 1.5 ft³/s
free surface = 80 ft
solution
we use mechanical pumping power delivered to water is
.............1
put here value
= (0.80)(20)
= 16 hp
and
now we get change in the total mechanical energy of water is equal to the change in its potential energy
..............2
and that can be express as
..................3
so
......4
solve it we get
hp
so here
due to frictional effects, mechanical power lost in piping
we get here
put here value
= 16 -13.614
= 2.37 hp
so mechanical power used to overcome frictional effects in piping is 2.37 hp
Answer:
Explanation:
g = Acceleration due to gravity at sea level =
R = Radius of Earth = 6371000 m
h = Altitude of observatory = 4205 m
Change in acceleration due to gravity due to change in altitude is given by
Weight at sea level
Weight at the given height
Change in weight
Her weight reduces by .
