if we compare light photons and energetic electrons which have constant velocity independent of energy
Answers
Light photons always travel at a constant speed (the speed of light) regardless of their energy, while the velocity of electrons is not constant and can vary with their energy.
Light photons and energetic electrons do not have constant velocities independent of energy. Light photons, which are particles of electromagnetic radiation, travel at a constant speed in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second) in a vacuum, denoted as the speed of light (c). This speed is a fundamental constant of nature and remains constant regardless of the energy of the photons. In other words, all photons, regardless of their energy, travel at the same speed in a vacuum.
On the other hand, energetic electrons do not have a constant velocity independent of their energy. According to classical physics, the velocity of an electron can vary depending on its energy. In classical mechanics, the kinetic energy of an object is related to its velocity. However, in the microscopic world of quantum mechanics, the behavior of particles such as electrons is described differently.
In quantum mechanics, the concept of particle velocity becomes less straightforward. Instead of velocity, quantum particles are described by wavefunctions, which represent the probability distribution of finding the particle at a certain location. The wavefunction of an electron evolves over time according to the Schrödinger equation, and it does not directly correspond to a well-defined classical velocity.
However, in certain situations, such as in electron beams or particle accelerators, electrons can be accelerated to high energies. In these cases, the energy of the electrons is related to their speed, but it is not a constant relationship. As the energy of the electrons increases, their speed can also increase, but it is not independent of their energy.

Describe the direction of each of the four forces and the objects that exert those forces. Include whether they are contact or noncontact forces.
Answers
1. The force of the ball pulling down on the string is equal in magnitude and opposite in direction to the force of the string pulling up on the ball. The direction of the force of the ball pulling down on the string is downwards, while the direction of the force of the string pulling up on the ball is upwards. Both of these forces are contact forces.
2. The force of the string pulling down on the attachment point (such as a hook or a nail) is equal in magnitude and opposite in direction to the force of the attachment point pulling up on the string. The direction of the force of the string pulling down on the attachment point is downwards, while the direction of the force of the attachment point pulling up on the string is upwards. Both of these forces are contact forces.
In summary, when a ball is hung by a string, there are two action-reaction force pairs: the force of the ball pulling down on the string and the force of the string pulling up on the ball, and the force of the string pulling down on the attachment point and the force of the attachment point pulling up on the string.
An airplane has a mass of 2.5×10^6 kg , and the air flows past the lower surface of the wings at 80 m/s .
If the wings have a surface area of 1600 m2 , how fast must the air flow over the upper surface of the wing if the plane is to stay in the air?
Answers
v_a = 178.74 m/s
using Bernoulli's theorem :-
P_a + ½ρ(v_a)² = P_b + ½ρ(v_b)²
Where;
P_a is pressure above wings
P_b is pressure below wings
v_a is speed above wings
v_b is speed below wings
ρ is density of air
We want to find V_a, so let's make V_a the subject;
v_a = √[(2(P_b - P_a)/ρ) + (v_b)²]
Now, we don't know (P_b - P_a)
(P_b - P_a) = Force/Area
(P_b - P_a) = mg/Area
We are given m = 2.5 × 10^(6) kg and area = 1600 m²
Thus, (P_b - P_a) = (2.5 × 10^(6) × 9.81)/1600 = 15328.125 N/m²
Density of air will be taken as 1.2 kg/m³
Thus;
v_a = √[(2(15328.125)/1.2) + (80)²]
v_a = √31946.875

If the ice extended right around the earth, forming a loop that that puck could go around in circles would the puck keep going forever?
Answers
If the ice extended right around the earth, forming a loop that the puck could go around in circles, the puck would not keep going forever. The laws of physics would eventually cause the puck to come to a stop. This is because of two factors: air resistance and gravity.
Air resistance is the force that opposes the motion of objects through the air. It is what causes things like parachutes to slow down as they fall. Even if there were no air in the hypothetical scenario of a loop of ice around the earth, there would still be air resistance. This is because the puck would be moving through the magnetic field of the earth, which would create a force that would oppose its motion.Gravity is the force that pulls objects towards each other. It is what keeps us on the ground and the planets in orbit around the sun. In the hypothetical scenario of a loop of ice around the earth, the puck would be subject to the gravitational pull of the earth. As it traveled around the loop, it would lose kinetic energy due to this gravitational force. Eventually, it would come to a stop at the bottom of the loop, where the force of gravity would be the strongest.The speed at which the puck would come to a stop would depend on a number of factors, including the size of the loop, the mass of the puck, and the force of gravity. However, in general, it is safe to say that the puck would not keep going forever if it were to travel around a loop of ice around the earth.For such more question on motion

Bobo the clown carries two red balloons that rub against a circus elephant, causing thr baloons to seperate. Each balloon aquires 1.2x10^-7 of charge. How large is the electric orce between them when the balloons are seperated by a distance of 0.5m
Answers
The electric force between the two balloons is approximately 1.04 x \(10^{-12}\) N.
Coulomb's Law:
The electric force between two charged objects can be calculated using Coulomb's Law, which states that the magnitude of the electric force F between two charged objects is directly proportional to the product of their charges (q1 and q2) and inversely proportional to the square of the distance (r) between them:
F = k * (q1 * q2) / r²
where k is the Coulomb constant, which has a value of approximately 9.0 x \(10^{9}\) N*\(m^{2}\)/\(C^{2}\).
In this case, each balloon acquires a charge of 1.2 x \(10^{-7}\) C, so the total charge on both balloons is 2 * 1.2 x \(10^{-7}\)C = 2.4 x \(10^{-7}\)C. The distance between the balloons is 0.5 m.
Plugging in these values into Coulomb's Law, we get:
F = (9.0 x \(10^{9}\) N*\(m^{2}\)/\(C^{2}\)) * [(1.2)²x (\(10^{-7}\) C)²/ (0.5m)²]
Simplifying this expression gives:
F = 1.0368 x \(10^{-12}\) N
Therefore, the electric force between the two balloons is approximately 1.04 x\(10^{-12}\) N.
What is magnitude?
Magnitude refers to the size or extent of something, usually measured in numerical or quantitative terms. It can refer to a physical quantity, such as length, mass, or volume, or it can refer to other measurable attributes, such as brightness, intensity, or force. In general, magnitude is a relative measure, meaning that it is typically expressed as a comparison between two or more things.

A man is pushing a heavy crate up an inclined plane into the back of semi trailer.What can the man do to make it easier to get the crate up the ramp
Answers
Answer:
B) Make the ramp longer
Explanation:
A machine is a device that makes work more easier and faster. A machine also saves time.
A ramp is a simple machine that is used to lift heavy object with a force that is lesser than the actually force needed. A ramp is in the shape of an inclined plane, which makes pushing an object easier than the required force needed.
The formula for a ramp is given by:
Force needed to push * length of the ramp = weight of object * height of ramp.
Force needed to push = (weight of object * height of ramp) / length of ramp
We can see that the force needed is inversely proportional to the ramp length. Hence for a ramp with longer length you need lesser force to raise the object.
