Answer:

The energy may be carried in the form of (1) radiation, where energy travels in the form of light, and (2) convection, where energy is carried by physical motion of upwelling solar gas.

Answer: v = (33320 - 340f2)/( f2 + 98)

Explanation: this question refers to Doppler effect, hence,

f1 = { V / (V - v)} x f2

f1 = 98Hz, f2 = 76 Hz, V = 340m/s, v = ?, fs = fsourcs

For f1,

98 = { 340 / (340 + v)} x fs ...(i)

for f2,

f2 = { 340 / (340 - v)} x fs ... (ii)

Divide (ii) by (i)

98/f2 = [{ 340 / (340 + v)} x fs]÷ [ 340 / (340 - v)} x fs]

98/f2 = {340 / (340 + v)} x fs x (340 - v)} / 340 x fs

98/f2 = (340 + v)/ (340 - v)

Cross multiplying

98(340 - v) = f2 (340 + v)

33320 - 98v = 340f2 + vf2

Collecting like terms

vf2 +98v = 33320 - 340f2

v(f2 +98) = 33320 - 340f2

v = (33320 - 340f2)/( f2 + 98)

Explanation:

It is known that energy balance relation is as follows.

$\Delta E_{system} = E_{in} - E_{out}$

Also, $W_{in} = \Delta U$

so, $W_{in} = mC_{v}(T_{2} - T_{1})$

According to the ideal gas equation,

$T_{2} = T_{1} \frac{P_{2}}{P_{1}}$

Putting the values into the above equation as follows.

$T_{2} = T_{1} \frac{P_{2}}{P_{1}}$

= $(520R) \frac{40psia}{30psia}$

= 693.3 R

Now, we will convert the temperature into degree Fahrenheit as follows.

693.3 - 458.67

= $234.63^{o}F$

From table A- $2E_{a}$

$C_{p}$ = 0.240 Btu/lbm R and $C_{v}$ = 0.171 Btu/lbm

Now, we will substitute the energy balance as follows.

$W_{in} = mC_{v}(T_{2} - T_{1})$

= $2 lbm \times 0.171 Btu/lbm R (693.3 - 520)$

= 59.3 Btu

Thus, we can conclude that final temperature of air is 59.3 Btu.

A skier is standing on a horizontal patch of snow. She is holding onto a horizontal tow rope, which is about to pull her forward

fredd [130]

The magnitude of the maximum force that the tow rope can apply to the skier without causing her to move will be 81.03 N,

<h3>What is the friction force?</h3>

It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).

It is defined as the product of the coefficient of friction and normal reaction.

On resolving the given force and acceleration. Mathematically aion in the different components and balancing the equation gets. Components in the x-direction.

The normal force is balanced by weight;

N = mg

The magnitude of the maximum force that the tow rope can apply to the skier without causing her to move is;

F = μN

F= μmg

F=0.14 × 59 kg × 9.81 m/s²

F = 81.03 N

Hence, the magnitude of the maximum force will be 81.03 N,
