Answer:

96.3%

Explanation:

Efficiency = Work input/Work output * 100%

Work done = Force * distance\

Work done by the engine is the work output = 700 * 0.55

Work output = 423.5Nm

Work done by you is the work input = 35.7*11.43

Work input = 408.051Nm

Efficiency = 408.051/423.5 * 100

Efficiency = 0.963 * 100

Efficiency = 96.3%

Hence the efficiency of the pulley system is 96.3%

Answer:

The mechanical advantage increases as the slope of the incline decreases. But the load will then have to be moved a greater distance. The ideal mechanical advantage (IMA) of an inclined plane is the length of the incline divided by the vertical rise, the so-called run-to-rise ratio.

Answer:

D: All

Explanation:

In cats, noise pollution causes what is known as acoustic stress in them.

In birds, noise pollution delays their nesting because it makes their songs which they use to probe to be at a low frequency.

Noise pollution affects humans because it can lead to loss of hearing, sleep disturbance, stress, high blood pressure e.t.c

Therefore, it affects Cats, birds and humans.

So option D is correct.

Answer: The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Answer:

Resistance of resistor A = 6.0 Ω and resistance of resistor B = 3.0 Ω

Explanation:

When the two resistors are in series, let V₁ = voltage in resistor A and R₁ = resistance of resistor A and V₂ = voltage in resistor B and R₂ = resistance of resistor B.

Given that V₁ + V₂ = 6.0 V and V₁ = 4.0 V,

V₂ = 6.0 V - V₁ = 6.0 V - 4.0 V = 2.0 V

Also, let the current in series be I.

So, V₁ = IR₁ and V₂ = IR₂

I = V₁/R₁ and I = V₂/R₂

equating both expressions, we have

V₁/R₁ = V₂/R₂

4.0 V/R₁ = 2.0 V/R₂

dividing through by 2.0 V, we have

2/R₁ = 1/R₂

taking the reciprocal, we have

R₂ = R₁/2

R₁ = 2R₂

From the parallel connection, let V₁ = voltage in resistor A and R₁ = resistance of resistor A and V₂ = voltage in resistor B and R₂ = resistance of resistor B. Since it is parallel, V₁ = V₂ = V = 6.0 V

Also, V₂ = I₂R₂ where I₂ = current in resistor B = 2.0 A and R₂ = resistance of resistor B

So, R₂ = V₂/I₂

= 6.0 V/2.0 A

= 3.0 Ω

R₁ = 2R₂

= 2(3.0 Ω)

= 6.0 Ω

So, resistance of resistor A = 6.0 Ω and resistance of resistor B = 3.0 Ω

The resistance of A is 6Ω while for B is 3Ω.

Potential difference is the amount of work done in moving a unit charge from one point to another.

When the two resistors are connected in parallel across the 6.0 V battery, the current in B is found to be 2.0 A, hence:

2 * Rb = 6 V

Rb = 3Ω

For the series connection:

I * 3 = (6 - 4)

I = 2/3 A

Hence:

(2/3) * Ra = 4

Ra = 6Ω

The resistance of A is 6Ω while for B is 3Ω.

Answer:

500000 approx........

...

Answer:

13. (i) The magnitude of the force that is pressing the lawn-mower directly into the ground is 25 N

(ii) The magnitude of the effective force that moves the mower forward is approximately 43.3 N

(iii) Because there are no net downward force acting on the lawn-mower

Explanation:

13. The given force pushing the lawn-mower = 50 N

The angle at which the force acts = 30° to the ground

The component of the pushing force are;

(i) The magnitude of the force that is pressing the lawn-mower directly into the ground = The vertical component of the pushing force

The vertical component of the pushing force, [tex]F_y[/tex] = 50 N × sin(30°) = 25 N

∴ The magnitude of the force that is pressing the lawn-mower directly into the ground = [tex]F_y[/tex]  = 25 N

(ii) The magnitude of the effective force that moves the mower forward = The horizontal component of the pushing force

The horizontal component of the pushing force, Fₓ = 50 N × cos(30°) = 25·√3 N ≈ 43.3 N

∴ The magnitude of the effective force that moves the mower forward = 25·√3 N  ≈ 43.3 N

(iii) The lawn mower moves forward and not downwards because according to Newton's first Law of motion, the lawn-mower moves forward because it is being acted on by a net forward directed horizontal force

However, according to Newton's third law, the reaction of the ground is equal to the weight of the lawn mower, therefore, there are no net vertical force acting on the lawn-mower, such that the lawn-mower remains in the initial horizontal level and does not move downward into the ground.

Answer:

Object's final momentum = 16.7 kg-m/s

Explanation:

Given that,

Impulse, J = 12.2 kg-m/s

Initial momentum, [tex]P_i=4.5\ kg-m/s[/tex]

We need to find the object's final momentum. We know that the impulse is equal to the change in momentum. So,

Impulse = change in momentum

[tex]J=P_f-P_i\\\\P_f=J+P_i\\\\P_f=12.2+4.5\\\\P_f=16.7\ kg-m/s[/tex]

So, the object's final momentum is 16.7 kg-m/s.

Given:

We know the relation,

→ [tex]Impulse = Change \ in \ momentum[/tex]

or,

→ [tex]J = P_f-P_i[/tex]

then,

→ [tex]P_f = J+P_i[/tex]

By substituting the values,

        [tex]= 12.2+4.5[/tex]

        [tex]= 16.7 \ kg-m/s[/tex]

Think of it like driving a car at high speed and then slamming on the breaks. Everything is going to fly to the front.:Waves at the Shoreline: As a wave approaches the shore it slows down from drag on the bottom when water depth is less than half the wavelength (L/2). The waves get closer together and taller. ... Eventually the bottom of the wave slows drastically and the wave topples over as a breaker. hope this helps have a nice night❤️❤️❤️

Answer:3 m/s

Explanation:

The resulting acceleration to move the 5Kg box is equal to 3m/s². Therefore, option (D) s correct.

Acceleration can be defined as the rate of change in the velocity of an object with respect to time. The acceleration of an object is a vector parameter with both magnitude and direction. Acceleration is also defined as the first derivative of the velocity w.r.t. time and the second derivative of position w.r.t. time and

According to Newton's 2nd law of motion, the force is equal to the product of the mass (m) and acceleration.

F = ma

And,   a = F/m

Therefore, the acceleration (a) inversely proportional to the mass (m).

Given, the force used to move the box, F = 15 N

The mass of the given Box, m = 5 Kg

The resulting acceleration, a  = 15/5 = 3 m/s²

Therefore, the acceleration of the box is equal to  3 m/s² when it is pushed with a force of 15 N.

[tex]R = 1.5* 10^{-10}m[/tex]

Explanation:

Given

[tex]r = 2.5 * 10^{-11}m[/tex] -- radius of hydrogen atom

See attachment

Required

Determine the radius of magnesium atom (R)

From the attachment, the ratio of a hydrogen atom to a magnesium atom is:

[tex]Ratio = 6mm : 36mm[/tex]

Simplify

[tex]Ratio =1 : 6[/tex]

Represent the radius as ratio:

[tex]Ratio = r : R[/tex]

Substitute [tex]r = 2.5 * 10^{-11}m[/tex]

[tex]Ratio = 2.5 * 10^{-11}m : R[/tex]

Equate both ratios

[tex]2.5 * 10^{-11}m : R = 1 : 6[/tex]

Express as fraction

[tex]\frac{2.5 * 10^{-11}m}{R} = \frac{1}{6}[/tex]

Cross Multiply

[tex]R * 1 = 2.5 * 10^{-11}m * 6[/tex]

[tex]R * 1 = 2.5 * 6* 10^{-11}m[/tex]

[tex]R * 1 = 15* 10^{-11}m[/tex]

[tex]R = 15* 10^{-11}m[/tex]

[tex]R = 1.5*10* 10^{-11}m[/tex]

[tex]R = 1.5* 10^{1-11}m[/tex]

[tex]R = 1.5* 10^{-10}m[/tex]

Hence, the radius of the magnesium atom is: [tex]1.5* 10^{-10}m[/tex]

Answer:

RT = 35 Ohms

Explanation:

Let the three resistors be R1, R2 and R3 respectively.

Given the following data;

R1 = 14 Ohms

R2 = 12 Ohms

R3 = 9 Ohms

To find the total resistance, RT;

Since all the resistors are connected in series, the total resistance is equal to the sum of all three resistance of the resistors.

RT = R1 + R2 + R3

Substituting into the equation, we have

RT = 14 + 12 + 9

RT = 35 Ohms.

Therefore, the total resistance of the circuit is 35 Ohms.
