Answer:

Efficiency has no physical units  (example   .85 = 85%)

The largest number would be 1 or 100%

An example of efficiency is:  work out/work in

or (work in - work lost to friction) / work in    would be an example of the efficiency of the process

Answer:

ITS TRUE.

Explanation:

Answer: The machine must apply the force over a shorter distance. That's because a machine doesn't change the amount of work and work equals force times distance. Therefore, if force increases, distance must decrease

FALSE

Answer:

When you use a machine, you apply force to the machine. This force is called the input force. The machine, in turn, applies force to an object. This force is called the output force.

The force you apply to a machine is called the effort force.

A machine is a device that is designed to make work easier by changing the direction or magnitude of a force. Machines can be simple, like a lever or pulley, or complex, like an engine or computer.

The basic principle behind all machines is the idea of mechanical advantage, which allows us to do more work with less effort by trading off the force for distance.

The efficiency of a machine is a measure of how much of the input energy is converted into useful output work.

The efficiency of a machine is calculated as the ratio of output work to input work, expressed as a percentage:

Efficiency = (Output work / Input work) x 100%

Output work refers to the amount of work that is done by the machine,

input work is the energy that is put into the machine to make it work.

The difference between the two is the energy that is lost to friction, heat, or other inefficiencies.

Mechanical advantage is a measure of the amplification of force achieved by a machine. It is defined as the ratio of the output force(Load) to the input force (effort). A machine with a mechanical advantage greater than 1 will make it easier to do work by amplifying the force applied to it.

The mechanical advantage of a machine can be calculated using the following formula:

Mechanical Advantage = Output Force(load) / Input Force(effort)

The velocity ratio is a measure of how much the speed of the machine is changed relative to the input speed. It is defined as the ratio of the distance moved by the effort or input force to the distance moved by the load or output force. Velocity ratio is commonly used in the analysis of machines such as pulleys and gears.

The velocity ratio of a machine can be calculated using the following formula:

Velocity Ratio = Distance moved by effort force / Distance moved by load force

Here in the question,

The force you apply to a machine is called the effort force. The effort force is the force applied to a machine, such as a lever or a pulley, in order to move an object or overcome resistance.

In simple machines, the effort force is used to overcome a load or resistance, which is the force that opposes the movement of the object being moved.

The relationship between the effort force and the load or resistance is often described in terms of mechanical advantage, which is the ratio of the output force to the input force. By applying a smaller effort force, a machine can increase its mechanical advantage and make it easier to move a larger load or overcome a greater resistance.

Hence the force we applied to a machine is called effort force.

Answer:

the current flowing through the battery is 4 A.

Explanation:

Given;

resistance of the three resistors in parallel, R₁, R₂ and R₃ = 3.0 Ω, 12 Ω, and 4.0 Ω

voltage of the battery, V = 6.0 V

The equivalent resistance is calculated as follows;

[tex]\frac{1}{R_T} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} \\\\\frac{1}{R_T} = \frac{1}{3} + \frac{1}{12} + \frac{1}{4} \\\\\frac{1}{R_T} = \frac{4 \ + \ 1 \ + \ 3}{12} \\\\\frac{1}{R_T} = \frac{8}{12} \\\\\frac{1}{R_T} = \frac{2}{3} \\\\R_T = \frac{3}{2} \\\\R_T = 1.5 \ ohms[/tex]

The current flowing through the battery is calculated as follows;

[tex]I = \frac{V}{R_T} \\\\I = \frac{6}{1.5} \\\\I = 4 \ A[/tex]

Therefore, the current flowing through the battery is 4 A.

A scooter is moving with a speed of 18 m/s. Its mass is 20 kg. What is the magnitude of its momentum?

A. 360 kg.m/s

B. 2 kg.m/s

C. 3600 kg.m/s

D. 1.1 kg.m/s

Speed (v) of a scooter = 18 m/s

Mass (m) = 20 kg

Magnitude of its momentum (p) = ?

Since, we know that,

p = mv

So,

p = 20 kg × 18 m/s

p = 360 kg.m/s

Answer:

True

Explanation:

Answer:

2892.31 N

Explanation:

Applying,

P = F×v................ Equation 1

Where P = power of the motor, F = Weight of the load the motor can lift, v = velocity

make F the subject of the equation

F = P/v.............. Equation 2

Given: P = 188 W, v = 0.065 m/s

Substitute into eequation 2

F = 188/0.065

F = 2892.31 N

Hence the weight of the load is 2892.31 N

Answer: If you solve for the orbit speed, v, in the mass formula, you can find how fast something needs to move to balance the inward pull of gravity: v 2 = (G M)/r . Taking the square root of both sides (you want just v not v 2), you get v = Sqrt.

Answer:

+ 0.07 C

Explanation:

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

Potential difference (V) = 12 V

Energy (E) = 0.418 J

Charge (Q) =?

The energy (E) , potential difference (V) and charge (Q) are related by the following equation:

E = ½QV

With the above formula, we can obtain the charge as follow:

Potential difference (V) = 12 V

Energy (E) = 0.418 J

Charge (Q) =?

E = ½QV

0.418 = ½ × Q × 12

0.418 = Q × 6

Divide both side by 6

Q = 0.418 / 6

Q = + 0.07 C

(a) The magnification is less than 1, the image is smaller than the object. Therefore, the image is real, inverted, and smaller than the object. (b)The  magnification is less than 1 in magnitude, the image is also smaller than the object. Therefore, the image is virtual, inverted, and smaller than the object.

In mirrors, magnification refers to the degree to which an object's size appears to be larger or smaller when reflected in a mirror. The magnification of a mirror is determined by its curvature and distance from the object being reflected.

We can use the mirror equation and magnification formula to solve the problem:

Mirror equation:

1/f = 1/do + 1/di

Magnification formula:

m = -di/do

where

f = focal length of the mirror

do = object distance from the mirror

di = image distance from the mirror

m = magnification

Given:

Radius of curvature, R = 25.0 cm (since the mirror is concave, R is negative)

focal length, f = R/2 = -12.5 cm

(a) For an upright pencil placed 46.0 cm from the mirror:

do = 46.0 cm

Using the mirror equation, we can solve for di:

1/f = 1/do + 1/di

1/-12.5 = 1/46.0 + 1/di

di = -17.2 cm

Since di is negative, the image is formed behind the mirror, which means it is real. Also, the magnification is:

m = -di/do = -(-17.2 cm)/46.0 cm = 0.374

Since the magnification is less than 1, the image is smaller than the object. Therefore, the image is real, inverted, and smaller than the object.

(b) For an upright pencil placed 5.0 cm from the mirror:

do = 5.0 cm

Using the mirror equation, we can solve for di:

1/f = 1/do + 1/di

1/-12.5 = 1/5.0 + 1/di

di = 3.33 cm

Since di is positive, the image is formed in front of the mirror, which means it is virtual. Also, the magnification is:

m = -di/do = -3.33 cm/5.0 cm = -0.666

Since the magnification is negative, the image is inverted. Since the magnification is less than 1 in magnitude, the image is also smaller than the object. Therefore, the image is virtual, inverted, and smaller than the object.
