The photon has momentum and energy but no mass is the correct statement.

Photons, also called light quanta, are small energy packages of electromagnetic radiation. The photon idea arose from Albert Einstein's description of the photoelectric effect published in 1905. So he proposed the existence of discrete packets of energy during the transmission of light. Einstein concluded that a quantum of light can also be assigned an impulse (hν/c). Significant energy values ​​and momentum strongly suggested that light quanta could be assigned to particles. This was later called a photon. A photon is thus defined as a discrete flux (or quantum) of electromagnetic (or light) energy. Photons have no mass, so they travel at the speed of light (3 × 10⁸ m/s).

Power is the rate of doing work. It is the energy supplied to the body per unit of time. It is of two types, instantaneous power which is calculated for a particular instant, and average power which is calculated over an interval of time Its S.I. unit is watts (W).

One watt is equal to one joule of energy transfered per second.

Given in the question

Energy transferred = 15 MJ

Time interval = 10 minutes

Before calculating the power, We need to convert the given values into their S.I. unit

1MJ = 1000000 J

So 15 MJ = 15 × 1000000 J

15 MJ = 15000000 J

Similarly,  1 minute = 60 seconds

So 10 minutes = 10 × 60 seconds

10 minutes = 600 seconds

Now,

Power =  Energy transferred/ Time Interval

Power = 15000000 / 600

Power = 150000/6

Power = 25000 Watts or W

The moon doesn't fall toward the Earth like apples do because it is in a state of constant freefall, known as orbit. This is due to the balance between the force of gravity pulling the moon towards the Earth and the moon's own inertia.

The moon doesn't fall toward the Earth like apples do because it is in a state of constant freefall, known as orbit. The moon orbits around the Earth due to the force of gravity. Gravity is the force of attraction between two objects with mass. In this case, the Earth's gravity pulls the moon towards it, but the moon also has its own motion called inertia. Inertia is the tendency of an object to resist changes in its motion.

When the moon was formed, it was already moving forward with a certain velocity. As it falls towards the Earth due to gravity, it also moves forward, resulting in a curved path known as an orbit. This balance between the gravitational force and the moon's inertia keeps it in a stable orbit around the Earth.

Yes, it is possible for both the pressure and volume of a monatomic ideal gas to change without causing the internal energy of the gas to change. This occurs when the gas undergoes an adiabatic process, meaning there is no heat transfer between the gas and its surroundings.

In an adiabatic process, the change in internal energy (ΔU) is solely dependent on the work done on or by the gas (W). According to the first law of thermodynamics, ΔU = Q + W, where Q is the heat transfer. Since Q = 0 in an adiabatic process, ΔU = W.

For the internal energy of the gas to remain constant (ΔU = 0), the work done on or by the gas must also be zero. This can be achieved through a specific path in the pressure-volume (PV) diagram, where the gas expands and does work on its surroundings, followed by compression, with the surroundings doing an equal amount of work on the gas. The net work done over this process will be zero, ensuring the internal energy remains unchanged.

In summary, it is possible for both the pressure and volume of a monatomic ideal gas to change without affecting its internal energy by undergoing an adiabatic process with zero net work done.

The frequency of the photon emitted when the dipole moment of a proton flips in a magnetic field of 2.5 T is approximately 53.5 MHz.

To find the frequency of the photon emitted when the dipole moment of a proton flips in a magnetic field, we can use the equation:

E = hf

where E is the energy of the photon, h is Planck's constant (6.626 × 10⁻³⁴ J·s), and f is the frequency of the photon.

We know that the energy of the photon is related to the dipole moment of the proton by:

E = μB

where μ is the dipole moment of the proton (1.41 × 10⁻²⁶ Am²) and B is the magnetic field (2.5 T).

Substituting the values into the equation, we have:

μB = hf

Solving for f, we get:

f = (μB) / h

Plugging in the values, we have:

f = (1.41 × 10⁻²⁶ Am² * 2.5 T) / (6.626 × 10⁻³⁴ J·s)

Calculating the value, we find:

f ≈ 5.35 × 10¹³ Hz

To convert the frequency to megahertz (MHz), we divide by 10⁶:

f ≈ 53.5 MHz

Therefore, the frequency of the photon emitted when the dipole moment of a proton flips in a magnetic field of 2.5 T is approximately 53.5 MHz.

Answer:

it's too cold/not enough oxygen for fire and people

Explanation:

Thus, the car travels 500 m after starting. Hence, the correct option is (c) 500 m.

Given that a car starting from rest accelerates at a constant 2.0 m/s² for 10 s, it then travels with constant speed it has achieved for another 10 s and finally slows to a stop with constant acceleration of magnitude 2.0 m/s². We need to determine how far it travels after starting.

To determine the distance traveled, we have to calculate the total distance traveled in each of the three phases and then add them together. Let's calculate each phase separately:

Phase 1: From rest, the car is accelerating at 2.0 m/s² for 10 seconds. We know that, Acceleration, a = 2.0 m/s²Time taken, t = 10 s Initial velocity, u = 0 m/s Distance, S = ?The formula for the distance covered during acceleration is given by, S = ut + 1/2at²S = 0 + 1/2 × 2.0 m/s² × (10 s)²S = 100 m So, the distance covered in Phase 1 is 100 m.

Phase 2: The car travels at constant speed for 10 seconds. The car continues to move with a constant speed for 10 seconds. Distance covered during the constant speed phase = Speed × Time As there is no acceleration during this phase, speed = acceleration × time + initial velocity = 2.0 m/s² × 10 s + 0 = 20 m/s Therefore, the distance covered in Phase 2 is 20 m/s × 10 s = 200 m.

Phase 3: Finally, the car comes to a stop with a deceleration of 2.0 m/s² for some time, say t seconds.

Distance covered during the deceleration phase, Acceleration, a = −2.0 m/s², Time taken, t = ?Initial velocity, u = 20 m/s Distance, S = ?

The formula for the distance covered during deceleration is given by:

S = ut + 1/2at²S = 20 m/s × t + 1/2 × (−2.0 m/s²) × t²S = 20t − t² m

Now, using the third equation of motion, we have,

v² = u² + 2

as where v = 0 m/s (final velocity), u = 20 m/s (initial velocity), ma = −2.0 m/s² (deceleration)

S = ?

Substituting the values in the above equation, we get:

0 = (20 m/s)² + 2 × (−2.0 m/s²) × S

Solving for S,S = 200 m

Therefore, the distance covered in Phase 3 is 200 m.

Finally, the total distance covered by the car can be obtained by adding the distances covered in the three phases.

Distance covered = 100 m + 200 m + 200 m = 500 m.

Calculation:

R1 = 1.5 meter

R2 = 1 meter

F1 = 0.36 N

F1/F2 = R2^2/R1^2

F2 = R1^2/R2^2 × F1

F2 = 2.25 / 1 × 0.36

F2 = 0.81

Electrostatic force is type of force which act between two charges it is  repulsive or attractive in nature.  If both charge in same type then it will be repulsive and when both are in opposite nature then it will be attractive in nature.

Mathematically,

F = k× Q1× Q2/r^2

So,

In above problems

R1 = 1.5 meter

R2 = 1 meter

F1 = 0.36 N

F1/F2 = R2^2/R1^2

F2 = R1^2/R2^2 × F1

F2 = 2.25 / 1 × 0.36

F2 = 0.81
