A 49 N coconut is in a 15 m tree. What is te potential energy of the coconut?
eduard

Answer:

735 J

Explanation:

From the question given above, the following data were obtained:

Weight (W) = 49 N

Height (h) = 15 m

Potential energy =?

Potential energy is simply defined as the product of weight of the object and height to which the object is raised. Mathematically, it is expressed as:

Potential energy = weight × height

With the above formula, we can obtain the potential energy of the coconut as follow:

Weight (W) = 49 N

Height (h) = 15 m

Potential energy =?

Potential energy = weight × height

Potential energy = 49 × 15

Potential energy = 735 J

Thus, the potential energy of the coconut is 735 J

A solenoid having an inductance of 5.41 μH is connected in series with a 0.949 kΩ resistor. (a) If a 16.0 V battery is connected
vekshin1

Answer:

(A) 9.14\times 10^{-9}sec

(B) 6.20\times 10^{-3}A

Explanation:

We have given inductance L=5.41\mu H=5.41\times 10^{-6}H

Resistance R=0.949kohm=0.949\times 10^3ohm

Time constant of RL circuit is equal to \tau =\frac{L}{R}

\tau =\frac{5.41\times 10^{-6}}{0.949\times 10^3}=5.70\times 10^{-9}sec

Battery voltage e = 16 volt

(a) It is given current becomes 79.9% of its final value

Current in RL circuit is given by

i=i_0(1-e^{\frac{-t}{\tau }})

According to question

0.799i_0=i_0(1-e^{\frac{-t}{\tau }})

e^{\frac{-t}{\tau }}=0.201

{\frac{-t}{\tau }}=ln0.201

{\frac{-t}{5.7\times 10^{-9} }}=-1.6044

t=9.14\times 10^{-9}sec

(b) Current at t=\tau sec

i=i_0(1-e^{\frac{-t}{\tau }})

i=\frac{16}{0.949\times 10^3}(1-e^{\frac{-\tau }{\tau }})

i=6.20\times 10^{-3}A
