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.

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.

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.

Radioactivity is a part of our earth - it has existed all along. Naturally occurring radioactive materials are present in its crust, the floors and walls of our homes, schools, or offices and in the food we eat and drink. There are radioactive gases in the air we breathe. Our own bodies - muscles, bones, and tissue - contain naturally occurring radioactive elements.

Answer:

Force = 150 Newton.

Explanation:

Given the following data;

Mass = 60kg

Acceleration = 2.5m/s²

To find the force;

Force = mass * acceleration

Force = 60 * 2.5

Force = 150 Newton.

Therefore, the force required to accelerate this mass is 150 Newton.

Horsepower is related to watt as: 1 horsepower = 746 W = 750 W approximately. 1 horsepower (HP) = 750 watt (approx.) The power is one watt when one joule of work is done in one second.

Answer:

1HP = 746 watts

Explanation:

The relation between Horsepower and watt is that One Horse Power is equal to 746 Watts .

Answer:

6kgm/s

Explanation:

Let the rate of gravity be the momentum of the body

Momentum = mass * velocity

Given

Mass = 2kg

velocity = 3m/s

Momentum = 2 * 3

Momentum = 6kgm/s

Hence the rate at which the gravity is working is 6kgm/s

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.

"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)."

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.

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.

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.

The current across the circuit is equal to 0.833A  if a voltage source of 5 V is connected at the input.

Ohm’s law states that the potential difference across a circuit is directly proportional to the current flowing through it. Assuming temperature and all other physical conditions remain constant. Resistance's S.I. unit is rho (Ω), and the current raises the temperature.

The mathematical expression of potential difference provided by Ohm/s law is:

V = IR

Where V is the voltage difference and R is the resistance and I the current flowing.

Given, the resistances in a series circuit, R = 3 + 3 = 6 ohm

The voltage difference across the circuit, V = 5 V

The current flowing through the circuit will be:

V = I × R

I = V/R

I = 5/6

I = 0.833 A

Therefore, the current across the circuit is equal to 0.833 A.

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

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.

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.
