A uniform meter rule is balanced by 80N and 20N from its ends. Find the position of its pivot from the 20N end. Show your working please

Answers

Answer 1

Answer:

80 cm

Explanation:

From the diagram attached,

Sum of clockwise moment = sum of anticlockwise

ΣACW = ΣCW

20x = 80(100-x)

Solve for x

20x = 8000-80x

20x+8x = 8000

100x = 8000

x = 8000/100

x = 80 cm.

The position of its pivot from the 20 N end is 80 cm.

What causes seafloor spreading, subduction, and the movement of
tectonic plates?

Answers

Answer:

Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth's mantle. Seafloor spreading creates new crust.

Each lunar cycle has one full moon, in which the relative positions of Earth, the sun, and the moon form in a straight line

Answers

Complete Question:

Each lunar cycle has one full moon, in which the relative positions of Earth, the sun, and the moon form in a straight line. Which list represents the position of Earth, the sun, and the moon during a full moon?

Group of answer choices.

A. Earth, sun, moon

B. sun, moon, Earth

C. moon, sun, Earth

D. sun, Earth, moon

Answer:

D. sun, Earth, moon

Explanation:

A lunar eclipse is a phenomenon that occurs when the Earth comes between the Moon and the Sun thereby causing it to cover the Moon with its shadow.

Simply stated, lunar eclipse takes place when the Moon passes or moves through the Earth's shadow thereby blocking any ray of sunlight from reaching the Moon. Thus, the full moon appears deep red (blood moon).

Also, a lunar eclipse would occur only when the Sun, Earth, and Moon are closely aligned to form a straight line known as the syzygy.

There are three (3) types of lunar eclipse and these are;

1. Total lunar eclipse.

2. Partial lunar eclipse.

3. Penumbra lunar eclipse.

Each lunar cycle has one full moon, in which the relative positions of Earth, the sun, and the moon form in a straight line. Thus, the list which represents the position of Earth, the sun, and the moon during a full moon is sun, Earth, and moon

Calculate the charge that flows through the cell in 1 minute. Each filament lamp has a power of 3 W and a resistance of 12 Ω

Answers

Answer:

24 Coulumbs

Explanation:

Given data

time= 1 minute= 6 seconds

P=2 W

R= 12 ohm

We know that

P= I^2R

P/R= I^2

2/12= I^2

I^2= 0.166

I= √0.166

I= 0.4 amps

We know also that

Q= It

substitute

Q= 0.4*60

Q= 24 Columbs

Hence the charge is 24 Coulumbs

A printer has a power of 100 W. It takes 30 seconds to print out a document. How much energy will it
have used?

Answers

100W translates to 100 watts consumed in 1 hour. Assuming the printer consumes electrical energy at a steady rate, then: 100 ÷ 60 = 1.6667 watts per minute. 1.6667 ÷ 2 = 0.8333 watts consumed in 30 seconds.

A printer has power of 100 W, and it takes time of 30 seconds to print out the document, then the power consumed in 30 seconds will be 0.8333 W.

What is Power?

The quantity of energy moved or changed per unit of time is termed as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in historical texts. A scalar quantity is power.

Power is connected to other factors; for instance, the power required to move a land vehicle is equivalent to the sum of the vehicle's velocity, traction force on its wheels, and aerodynamic drag.

Assuming the printer consumes electrical energy at a steady rate, then:

100 ÷ 60 = 1.6667 watts per minute.

Now, calculate the power consumed in 30 seconds,

1.6667 ÷ 2 = 0.8333 watts.

Therefore, the power consumed in 30 seconds will be 0.8333 watts.

If a car is moving with a speed of 5 km/h on a highway. Find the distance travelled by the car in 2 hours?.​

Answers

Answer:

Distance = 10 kilometers.

Explanation:

Given the following data;

Speed = 5km/h

Time = 2 hours

To find the distance traveled;

Distance = speed * time

Distance = 5 * 2

Distance = 10 kilometers

Therefore, the distance travelled by the car is 10 kilometers.

Your car battery is a 12 V DC source. Typically you might find a fuse that can handle a 5 amp surge. What resistance is that fuse protecting?

Answers

Answer:

2.4 ohms

Explanation:

From the question,

Applying ohm's law,

V = IR.................... Equation 1

Where V = Voltage of the car battery, I = current, R = resistance

Make R the subject of the equation

R = V/I.................. Equation 2

Given: V = 12 V, I = 5 amp.

Substitute these values into equation 2

R = 12/5

R = 2.4 ohms

City A is much larger than city B, but they are located at the same latitude and elevation. However, city A is receiving more rainfall than city B. Given this information, which statement most likely explains why?

Answers

Answer:

City A has more large buildings than city B, which force more air upward into the atmosphere.

Explanation:

The statement which most likely explains why city A is receiving more rainfall than city B despite its larger area is because "City A has more large buildings than city B, which force more air upward into the atmosphere."

This is evident in the fact that city A's large buildings contribute a stream of lift to raise warm, moist, surface air into the humid air right over the area, where it then transformed into rain clouds.

If the distance between 2 charged particles is double, the force between them changes by a factor of?

Answers

Answer:

See explanation

Explanation:

Given that;

q1 and q2 are the magnitudes of the two charges while r1 is the distance between the charges.

F1 =kq1q2/r1^2

Then,

F2 = kq1q2/(2r1)^2

F2 = kq1q2/4r1^2

So,

F2 = 1/4 F1

The force between the charges changes by a factor of 1/4.

Please help!! How is turning a door knob mechanical energy?

Answers

Answer:

Explanation:

It is mechanical energy because you are pushing the doorknob to the right you are manually doing it

Turning a knob is a form of mechanical energy. This is because, turning a knob requires rotational kinetic energy which is a form of mechanical energy.

What is Mechanical energy?

Mechanical energy is the sum of the potential energy and the kinetic energy of a system. The principle of conservation of the mechanical energy states that if an isolated system is subjected only to the conservative forces, then the mechanical energy will be constant.

Turning a door knob requires some amount of rotational kinetic energy. The rotational speed due to this kinetic energy of the door knob and its moment of inertia combines to give the rotational kinetic energy.

Rotational kinetic energy of an object under rotation increases with the rotating speed and it can be passed on to the system when the turning speed of the object decreases.

A The temperature of the gas

B The number of molecules in the gas

C The density of the gas

D The total volume of the gas

Answers

Quantity is most closely related to the speed of gas particles is the temperature of the gas.

Specifically, the speed of the molecules in a gas is dependent on its temperature (the higher the temperature the faster the gas molecules move). Another way to think of it is that the temperature of a gas is a measure of the average kinetic energy of that gas.

What is temperature ?

"Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature)."
