Q: How do you determine speed over a crooked path? Explain.
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.

What is the unit for efficiency?
What is the biggest number the
efficiency can be?
How do you work out the % efficiency?
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

What is the correct order of tasks for washing dishes in a three-compartment sink?
Answer:
The summary of the given statement is explained below throughout the explanation segment.
Explanation:
Drain certain surfaces throughout warm water of such soap during the very first sink. This same sanitizing of bacteria would not destroy whether grime would be in the direction.Exfoliate the plates throughout plain water during the secondary drain. As with grime, the residual soap could avoid the kill off bacteria and viruses by the sanitizer.When a charge moves between
two points that have a potential
difference of +12.0 V, its electric
potential energy increases by
0.418 J. What is the amount
of the charge?
Include the correct sign, + or -
(Unit = C)
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

Three resistors, 3.0 Ω, 12 Ω, and 4.0 Ω, are connected in parallel across a 6.0-V battery as shown above. What is the current through the battery?
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.

: where are you likely to find a cooling plant located in the duckwork? A. single family home B. A large apartment C. large factory D. A medium sized offices
Answer:
Option C
Explanation:
In a large sized factory, it is essential to create cooling system based on duct work because it can then be able to regulate cooling of any section of the factory from one place. Also, ductwork cooling is preferred in large spaces such as big offices building, towers, factories etc.
Hence, option C is correct

Lloyd walks faster than
Ronald, with a speed of
about 0.65 m/s. The canteen
is 15 meters away from their
dassroom. How many
minutes will take her to go
to the canteen?
Answer:
Time = 2.6 minutes
Explanation:
Given the following data;
Speed = 0.65 m/s
Distance = 15 meters
To find the time to get to the canteen;
Mathematically, time is given by the formula;
Time = distance/speed
Substituting into the formula, we have;
Time = 15/0.65
Time = 23.08 seconds
To minutes = 60/23.08 = 2.6 minutes
A battery is connected to a 10 resistor and produces a current of 0.2 A in the circuit. If the resistor is replaced with a 20 resistor, what is the new
current in the circuit?
Answer:
0.1 A
Explanation:
From the question,
V = IR............ Equation 1
Where V = Voltage, I = current, R = Resistance.
Given: I = 0.2 A, R = 10 ohms.
Substitute into equation 1
V = 0.2(10)
V = 2 volt,
If the resistor is replaced with a 20 resistor, The nwe current is
I = V/R................ Equation 2
I = 2/20
I = 0.1 A
If a machine increases force it must apply the force over a long distance? True or false
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

The force you apply to a machine is called the what force?
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.
What is a machine?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.
