Answer:

Waste energy = Energy Input - Useful Energy Output (Principle of Energy Conservation)

Efficiency = Useful Energy Output/Energy Input (Definition of Energy Efficiency)

Explanation:

The waste energy is the difference between energy input and useful energy output. Then, the word equation is:

Waste energy = Energy Input - Useful Energy Output (Principle of Energy Conservation)

The efficiency, measured in percentage, is the ratio of the useful energy output to the energy input and multiplied by 100. Then, the word equation is:

Efficiency = Useful Energy Output/Energy Input (Definition of Energy Efficiency)

Answer:

22.5/s is the frequency of the wave

Given:

We know,

Answer: the walls of hollow organs such has blood vessels, digestive tract organs, urinary bladder, and uterus.

Explanation:

Answer:

The deceleration is -7.85x10³ rad/s².

Explanation:

The angular speed (ω) is related to frequency (f) as follows:

[tex] \omega = 2\pi f [/tex]

When the frequency is 30 Hz the angular speed is:

[tex] \omega_{i} = 2\pi f = 2\pi*30 Hz = 188.5 rad/s [/tex]

Now, when the frequency is 20 Hz the angular speed is:

[tex] \omega_{f} = 2\pi*20 Hz = 125.7 rad/s [/tex]

Finally, the angular acceleration (α) can be found using the following equation:

[tex] \omega_{f}^{2} = \omega_{i}^{2} + 2\theta \alpha [/tex]

Where:

θ: is the angular displacement = 72°

[tex] \alpha = \frac{\omega_{f}^{2} - \omega_{i}^{2}}{2\theta} [/tex]

[tex] \alpha = \frac{(125.7 rad/s)^{2} - (188.5 rad/s)^{2}}{2*72*\frac{2\pi rad}{360}} = -7.85 \cdot 10^{3} rad/s^{2} [/tex]        

Therefore, the deceleration is -7.85x10³ rad/s².

Answer:

A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. The wings force the air downward and that pushes the plane upward.

Explanation:

planes stay in air because of 2 reasons :

Plane's wings are designed to push the air downwards and letting the plane to lift off and stay in air..

Answer:

The correct answer is - pollens.

Explanation:

During the springtime of the year, Pollination is common among plants and there are many plants that use air or wind as the medium for spreading the pollens. Such weeds, grass, and trees use this type of wind-pollination.

These are the most common allergens during this time that leads to sneezing and suffering from allergic reactions. Pollens are too heavy to be airborne for a longer time or they are inhaled from the air and lead to allergic reactions.

Answer:

Trains stop in their own time.

Every freight train, every situation, every load is different. The distance it takes to halt a train in an emergency is based on multiple factors: the speed when the brakes are applied, the track's incline, the number of cars hooked behind the locomotives and the loading of those cars, the "brake delay" inherent in the train's hydraulic system, the friction-causing metallurgy of the wheels and tracks, the weather.

Even the engineer behind the controls can't know on any given day how long it would take to stop the train.

"There is no specific rule of thumb on that," said Greg Udolph, general manager of the Texas State Railroad, a freight and tourist line in East Texas running from Palestine to Rusk. "If the track is wet with dew it changes. Everything that can affect it does. A train takes as long to stop as it takes to stop. Sometimes it can be a mile. Sometimes it's less, sometime's it's more."

Answer:

a

Explanation:

time=540×60

=32400

f=1÷t

=1÷32400

f=3.09

f=3

The frequency is 3 Hz.

To calculate the frequency of the pendulum, the values given are

t = 540 minute

       The frequency of the simple pendulum can be described through the pendulum moves and come back to its own position for the specific period of the time. Also the pendulum frequency depends upon its length and mass.

Thus, frequency formula can be,

                        ω = √g/l

                       T = 2π / ω

        Frequency, f = 1 / T = ω / 2π

As we have to find the frequency, the time period will be reciprocal.

                        f = 1/ T Hz.

t = 540 per minute

 = 540 × 60 seconds

 = 32400 seconds

f = 1 / 32400

 = 3.08 × 10 ⁻⁶

f = 3 Hz

The frequency thus calculated as 3Hz.

Hence, Option A is the correct answer.

Answer:

Explanation:

I think so I'm not 100% sure sorry

Explanation:

Given that,

Object distance, u = -40 cm (negative for concave mirror)

The radius of curvature of the mirror, R = 64 cm

Radius of curvature = 2(Focal length)

f = -32 cm (negative for concave mirror)

Using mirror's formula,

[tex]\dfrac{1}{v}+\dfrac{1}{u}=\dfrac{1}{f}\\\\\dfrac{1}{v}=\dfrac{1}{f}-\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{(-32)}-\dfrac{1}{(-40)}\\\\v=-160\ cm[/tex]

So, the image will form at a distance of 160 cm from the mirror.

Answer:

The thermal energy absorbed is 66.98 kJ.

Explanation:

The thermal energy absorbed can be found by using the following equation:

[tex] Q = mC\Delta T [/tex]

Where:

Q: is the thermal energy =?

m: is the mass of water = 2.00x10² g

ΔT = T₂ - T₁ = 140 °C - 60 °C = 80 °C

C: is the specific heat of water = 4.186 J/(°C*g)

Hence, the thermal energy absorbed is:  

[tex]Q = mC\Delta T = 2.00 \cdot 10^{2} g*4.186 \frac{J}{^{\circ} C*g}*80 ^{\circ} C = 66976 J = 66.98 kJ[/tex]

Therefore, the thermal energy absorbed is 66.98 kJ.

The thermal energy absorbed will be 66.98 kJ.heat loss is inverse to heat gain.

Heat gain is defined as the amount of heat required to increase the temperature of a substance by some degree of Celcius.

Given data;

Q(thermal energy) =?

m(mass of water) = 2.00x10² g

C(specific heat of water) = 4.186 J/(°C*g)

ΔT = T₂ - T₁

ΔT = 140 °C - 60 °C

ΔT = 80 °C

It is given by the formula as ;

[tex]\rm Q= mcdt \\\\ Q= 2.00x10^2 \times 4.186 \times 80 \\\\ Q=66.98 \ kJ.[/tex]

Explanation:

Remark

If, when it reaches its maximum height where the PE is the greatest, that the maximum energy is when the ball is first kicked. That would mean its starting energy is 10 Joules.

Formula

KE = 1/2 m v^2

Givens

KE = 10 J

m = 0.2 kg

v = ?

Solution

10 = 1/2 * 0.2 * v^2

10 * 2 = 0.2 * v^2

20 = 0.2 * v^2

20/0.2 = v^2

100 = v^2
