Answer:
Explanation:
Given
No of logs
diameter of log
Length of log
42 % of log volume(V) is above water when no one is on raft
so 58 % of log volume(V) is submerged in the water
Weight of 14 log
Buoyancy force on 14 logs
as system is in equilibrium so
Specific gravity of log
Since there are 3 links in the spring, the angel θ for
equilibrium of the spring is the angle where there are no nte motion of the
spring. It can be easily be solve by jus diving 360 by the number of links.
360/3 = 120 degree is the angle of equilibrium
Answer:
960 Watt
Explanation:
From the question,
Electric power = Voltage squared/Resistance
P = V²/R ..................... Equation 1
Where P = power, V = Voltage, R = Resistance
Given: V = 120 volts, R = 15 ohms.
Substitute these values into equation 1
P = 120²/15
P = 14400/15
P = 960 Watt
