The water in a deep underground well is used as the cold resevoir of a Carnot heat pump that maintains the temperature of a hous

e at 308 K. To deposit 13900 J of heat in the house, the heat pump requires 900 J of work. Determine the temperature of the well water.

Answer:

The temperature of well water be 288.07 K

Explanation:

We have given Heat in house Q_H=13900J

Work done W = 900 J

Efficiency is given by \eta =\frac{W}{Q_H}=\frac{900}{13900}=0.0647

Efficiency is also given by \eta =1-\frac{T_L}{T_H}, here T_L is lower temperature and T_H is higher temperature

So 0.0647=1-\frac{T_L}{T_H}

0.0647=1-\frac{T_L}{308}

T_L=288.07K

So the temperature of well water be 288.07 K

An FM radio consists of a series RLC circuit with a 6.57 pF (peco – 10-12) capacitor. If a person is dialed into a station broad
faust18 [17]

Answer:

3.6 x 10⁻⁷ H

Explanation:

C = capacitance of the capacitor = 6.57 x 10⁻¹² F

L = inductance of the inductor = ?

f = frequency of broadcasting system = 103.9 MHz = 103.9 x 10⁶ Hz

frequency is given as

f = \frac{1}{2\pi \sqrt{LC}}

103.6\times 10^{6} = \frac{1}{2(3.14)\sqrt{(6.57\times 10^{-12})L}}

Inserting the values

L = 3.6 x 10⁻⁷ H

An object experiences an acceleration of 6.8m/s2.As a result,it accelerates from rest to 24m/s.How much distance did it travel d
Hitman42 [59]

The distance covered by the object is 42.4 m

Explanation:

The motion of the object is a uniformly accelerated motion (at constant acceleration), therefore we can use the following suvat equation:

v^2 -u^2 = 2as

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance covered

For the object in this problem, we have:

u = 0 (it starts from rest)

v = 24 m/s (final velocity)

a=6.8 m/s^2

Solving for s, we find the distance travelled by the object:

s=\frac{v^2-u^2}{2a}=\frac{24^2-0}{2(6.8)}=42.4 m
