Answer:
P = 216 Watts
Explanation:
Given that,
Resistance 1,
Resistance 2,
Voltage, V = 36 V
We need to find the power dissipated by the 6 ohms resistor. In case of parallel circuit, voltage throughout the circuit is same while the current is different.
Firstly, lets find current of the 6 ohms resistor such that,
V = IR
The power dissipated by 6 ohms resistor is given by :
So, the power dissipated across 6 ohm resistor is 126 watts.
Refer to the figure shown below.
From the geometry,
y = 100 - (44 - 3) = 59 ft
From the Pythagorean theorem,
x² = 100² - 59² = 6519
x = 8007403 ft
Calculate the central angle, θ.
cos θ = 59/100 = 0.59
θ = 53.84° = 0.9397 radians
Calculate the arc length pq.
S = pq = 0.9394*100 = 93.94 ft
Calculate the angular velocity.
ω = (0.9397 radians)/(5 s) = 0.188 rad/s
Calculate the tangential velocity.
v = (100 ft)*(0.188 rad/s) = 18.8 ft/s
Calculate the time for 1 revolution.
T = (2π rad)/(0.188 rad/s) = 33.4 s
Answers:
The angular speed is 0.188 rad/s
The tangential speed is 18.8 ft/s
The time for one revolution is 33.4 s
