Answer:
v = sqrt[2*(F*h*cot(theta)-mgh)/m]
Explanation:
Work = KE + Ug
F*r=1/2mv^2+mgh
1/2mv^2=F*r-mgh
v=sqrt[2(F*r-mgh)/m]
r=h/tan(theta)=h*cot(theta)
Answer:
The maximum power delivered by the power supply is 0.81 W.
Explanation:
Given that,
Inductance L= 2.0 H
Resistance R = 100 ohm
Voltage = 9.0 V
We need to calculate the power
Using formula of power

Where, P = power
V = voltage
R = resistance
Put the value into the formula


Hence, The maximum power delivered by the power supply is 0.81 W.
Explanation:
1. swimmer is having kinetic energy as it is moving with velocity of 6 meter per second..
2. Intial velocity = 6 , Final velocity = 0
Average velocity = u +v /2
6+0/2 = 6/2 = 3
So, 3 is velocity
Kinetic energy = ½ mv²
= ½× 80 × (3)²
= 40×9
= 360 Joule Answer
