H = height of the pole = ?
BC = ED = height of the transit = 4 ft
CD = BE = distance moved away from the base of the pole = 140 ft
Consider the ΔABE
tan44 = AE/BE
tan44 = h/140
h = 140 tan44
h = 135.2 ft
H = height of pole = AE + ED = h + ED = 135.2 + 4
H = 139.2 ft
Answer:
Gravitational potential energy (GPE) = 107.8J
Explanation:
Gravitational potential energy (GPE) = mgh
Where mass(m) = 11kg
Acceleration due to gravity(g) = 9.8m²/s
height = assumed to be 1m
Force(F) = mg
Force(F) = 11×9.8 = 107.8N
Gravitational potential energy (GPE) = 107.8×1
= 107.8J
Answer:
(a). The impedance of the air conditioner is 11.11 ohm.
(b). The average rate of energy delivery is
Explanation:
Given that,
Voltage = 120 V
Resistance = 11.0 ohm
Inductive reactance = 1.59 ohm
(a). We need to calculate the impedance of the air conditioner
Using formula of impedance
Put the value into the formula
(b). We need to calculate the average rate of energy delivery
Using formula of power
Where, I=Current
R = resistance
Put the value into the formula
Hence, (a). The impedance of the air conditioner is 11.11 ohm.
(b). The average rate of energy delivery is
Answer:
The mnemonic I can use to memorize the metric prefixes in this order is: Gigantic Monsters Killed One Million Men Napping Peacefully. All right, so again, gigantic monsters killed one million men napping peacefully.
