Rotation refers to the spinning of a planet, moon, or other object on its own axis. The Earth completes one rotation every 24 hours, which is what causes day and night.

Revolution, on the other hand, refers to the movement of an object in orbit around another object. For example, the Earth revolves around the sun, which takes about 365.25 days to complete one revolution. The axis of rotation is an imaginary line that runs through the center of an object and around which it rotates. In the case of the Earth, its axis of rotation is tilted at an angle of 23.5 degrees, which is what causes the changing seasons. An orbit is the path that an object takes as it revolves around another object, like the Earth's orbit around the sun. Finally, a leap year is a year that has an extra day, February 29th, which is added to the calendar to keep it in sync with the Earth's revolution around the sun. This is necessary because the Earth's orbit around the sun is actually slightly longer than 365 days, so the extra day helps to correct for this discrepancy. On a clock, the hour hand will rotate every 23 and 6 hours, or 23/6 For the 23rd and 6th hours of a clock's rotation, we must determine the radians with the hour hand. Completely around the circle with the radius constitutes one revolution. The radius subtends a 2 radian angle at the circle's centre after one complete rotation. We will use the knowledge that 2 radians equal 360 degrees to demonstrate the conversion of 1 radian to degrees.

Answer:

   (3) the same before and after the collision

Explanation:

The sum of products of mass and velocity before the collision is ...

  (2 kg)(0.250 m/s) + (2 kg)(0 m/s) = 0.50 kg·m/s

The sum of products of mass and velocity after the collision is ...

  (2 kg +2 kg)(0.125 m/s) = 0.50 kg·m/s

The total momentum is unchanged.

Water has a 4,200 J/kg°C (joules per kilogramme per degree Celsius) specific heat capacity. This indicates that 4,200 J are required to raise the boiling point of 1 litre of water to 1°C.

1 g of water consumes calories to heat from its critical temperature of 0 C to its boiling temperature of 100 C. Yet, in order to turn 1 gram of water at 100 °C into 1 g of vapour at 100 °C, 540 units of energy are needed. The enthalpy of vaporization is what is causing this.

Water has a specific warmth capacity of 4200 Jkg/1K, ice has a specific boiling point of 2100 Jkg/1K, ice has a hidden fusion temperature of 3.36 105 Jkg/1, and water has a latent heat of changes due of 2.25 106 Jkg/1.

Because of the reduced density of the hydrocarbon fluids and gases, oil and natural gas move from sedimentary source rocks to reservoir rocks after their production.

By implication, good reservoir rocks need to have high porosity and permeability. The term "natural gas" refers to a variety of gaseous hydrocarbons produced beneath the surface of the Earth and entrapped in the pores of sedimentary rocks.

Although not always, these natural gases have close ties to the various liquid hydrocarbons, primarily liquid paraffins, naphthenes, and aromatics, which together make up oil.

The following are some characteristics of the depositional environment that have an impact on sedimentary rock properties:

(1) Lithology: This term explains the minerals that make up the crystals that make up sedimentary rock as well as the texture of those crystals. This depositional environment is where these minerals are found.

(2) Structure. Rock can have a variety of structures, including cross-bedding and ripple markings that indicate the direction of wind and water flow.

(3) Fossil content. Sedimentary rocks include fossils that are imbedded in them.

Frequency is the number of wave cycles per second, measured in hertz (Hz), and related to wavelength and velocity.

In material science, recurrence is a proportion of the quantity of cycles or motions of a wave that happen in a given time. It is generally addressed by the image f and is estimated in hertz (Hz), which addresses the quantity of cycles each second. The recurrence of a wave is connected with its frequency and speed, where the frequency is the distance between progressive pinnacles of the wave, and speed is the speed at which the wave voyages. The higher the recurrence of a wave, the more cycles or motions it has per unit of time, and the more limited its frequency. Recurrence is a key idea in numerous areas of material science, including electromagnetism, optics, and acoustics.

To protect wiring before it gets to the fuse box, a circuit breaker is installed.

A circuit breaker is a device that automatically switches off a circuit's flow of electricity when it detects a fault. This action helps to prevent fires, equipment damage, and electrical hazards. It is a device that functions as a safety guard for electrical circuits to keep the devices from becoming overloaded or shorted.

Circuit breakers safeguard the electrical equipment by breaking the flow of current when the current exceeds the permitted level, or when the current exceeds the rated level of a wire in a circuit. The fuses are a different type of protection that is installed between the device being protected and the circuit's power source.

Fuses are designed to stop the flow of electrical power when the current exceeds the fuse's safe capacity. In most cases, a fuse will blow before the electrical current reaches the device being protected, protecting it from damage.

The acceleration of the motorcycle is 0.8 m/s².

Hence, Option a) 0.8 m/s² is the correct answer.

Given the data in the question;

Since the motorcycle stopped

then, initial speed; \(u = 0 m/s\)

final speed; \(v = 12m/s\)

time; \(t = 15s\)

acceleration = ?

To get our acceleration, we use the first equation of motion.

This equation states that;

\(v = u + at\)

so, we simply substitute in our given values and solve for "a"

\((12 m/s) = (0 m/s) + ( a * 15s )\)

\(12 m/s = ( a * 15 s )\)

\(a = \frac{12m/s}{15s}\)

\(a = 0.8 m/s^2\)

Therefore, the acceleration of the motorcycle is 0.8 m/s²

It is the combination of social and historical factors.

A. The speed of the waves will remain unchanged if the mass is tripled without stretching the wire.

B. The speed of the waves will be halved if the wire is replaced with an identical one, except twice as long. This is because the waves will have to travel twice the distance in the same amount of time.

C. The speed of the waves will remain unchanged if the wire is replaced with one of the same lengths, but two times as heavy.

D. The speed of the waves will be halved if the wire is stretched to thrice its original length. This is because the waves will have to travel thrice the distance in the same amount of time.

E. The speed of the waves will be halved if the mass is increased by a factor of 18.0 and the wire is stretched to double its original length. This is because the waves will have to travel twice the distance in the same amount of time. The speed of the waves will thus be V/2.

The answer to part (a) would change if the electric field was not perpendicular to the rod. The force exerted by an electric field on a charged particle is given by the equation:

F = qE

where F is the force acting on the charged particle, q is the particle's charge, and E is the electric field.

When the electric field is not perpendicular to the rod, the component of the electric field perpendicular to the rod causes a deflection of the charged particles, but the component of the electric field parallel to the rod does not.

As a result, the force on the charged particles will be less than the full strength of the electric field, and the amount of deflection will be less than it would be if the electric field were perpendicular to the rod. Therefore, the answer to part

To make a proton undergo cyclotron motion, the magnetic field must be perpendicular to the direction of motion of the proton.

This is because the force on a charged particle moving in a magnetic field is given by the Lorentz force: F = q(v x B) where F is the force on the charged particle, q is the charge of the particle, v is the velocity of the particle, and B is the magnetic field. The direction of the force is perpendicular to both v and B, and is given by the right-hand rule. If the magnetic field is perpendicular to the direction of motion, the force will always be perpendicular to the velocity, which causes the proton to undergo circular motion in a plane perpendicular to the magnetic field. This is called cyclotron motion.
