According to the question: The lamp should be placed 11 cm from the mirror.

Mirror is an object which reflects light in such a way that images of nearby objects are visible. It is a surface which can reflect light in an exact way. Mirrors are used for various purposes like for making up, for decorating a room, for security purposes, and also for various scientific experiments. Mirrors are usually made up of two pieces of glass which are either flat or curved with a reflective coating on one side.

This coating is usually made up of metal, such as silver, and is highly reflective. Mirrors can also be made up of other materials such as plastic and other metals. By reflecting light, mirrors can help to create illusions and also create an optical illusion.

This is because the distance between the mirror and the lamp should be equal to the sum of the focal length of the mirror (15 cm) and the distance between the patient and the mirror (1.0 m). Therefore, the distance between the mirror and the lamp should be 1.0 + 15/100 = 2.15 m.

Use the thin lens equation to solve this

(1/s)+(1/s prime)=(1/f)

You are looking for the s value, which is the lamps distance from the mirror. s prime is the distance to the patient, and f is 10 cm.

(1/s)+(1/1.1)= (1/0.1)

= 11.000001 cm

When two objects of different masses are subjected to a force of the same strength, the one with less mass will experience a higher change in velocity.

Each object pulls the other when two objects come into contact. Imagine using a bat to strike a softball. The ball is pushed away by the bat when it collides with it. The bat experiences force from the ball as well.

Even if two colliding objects have masses that are very different from one another, they will nevertheless exert equal forces on one another. An object always experiences an impetus and a shift in momentum during a collision. The impulse that an object encounters during a collision is equal to its variation in speed.

A) The weight of the orange is 2.4N and B) It takes 1.542s  for the orange's momentum to change by 6. 1 kg·m/s.

Weight is the measure of the force of gravity on an object. It is a measure of the amount of matter present in an object and is measured in units such as kilograms, pounds, or ounces. Weight is the same no matter where an object is located, as gravity is a universal force. Weight is different than mass, which is the amount of matter in an object regardless of gravity. Mass is measured in kilograms, grams, or other metric units. Weight can be calculated by multiplying an object's mass by the acceleration due to gravity.

(a)

The rate of change of the momentum of any object is equal to the force acting on the object.

The orange is free falling so the force acting on the orange will be equal to to weight of the orange.

Then, the weight of the orange is 2.4N.

(b)

Given the initial momentum is 2.4 kg·m/s2

Calculate the time required for the oranges momentum to change by 6.1 kg·m/s,

W × t

= final momentum - initial momentum

= 6.1 - 2.4(t)

An object moving at a constant pace travels 5 meters in the first second; thus, it travels 45 meters in the third second.

The measurement of such a change in the speed called acceleration. Acceleration frequently, though not always, denotes a shift in speed. A thing that moves in a circle at a constant speed has still been moving forward since the direction of the motion is changing.

Calculation

the object starts from rest i.e. initial velocity, u = 0

and have uniform acceleration.

S = 5m and t = 1s

According to the formula of distance,

S = ut + 1/2 at²

5 = 0×1 + 1/2 a×1²

5 = 1/2a

a = 10m/s²

again, t = 3s

now, v = u + at

v = 0 + 10×3

v= 30m/s

Now, 2aS = v²-u²

2aS = 30²-0

2×10×S = 900

S= 900/20 = 90/2

S = 45m

11223.9J or 11.2239 kJ is the total internal energy of the gas.

Internal energy, which results from the motion of matter at the molecular level, is a type of energy that exists in all systems. For internal energy, the letter U is used, and the joule is the unit of measurement (J).

As a substance changes from one state or phase to another—from solid to liquid to gas—its internal energy also rises. It is possible to imagine planetary bodies as a fusion of heat engines and heat reservoirs.

The heat engines transform some of the thermal energy stored in the heat reservoirs into different forms of mechanical, electrical, and chemical energy.

The formula for total internal energy of gas is

(3/2)nRT

where n = amount of substance

R = Ideal gas constant

T = temperature

Put the value in the equation

(3/2)nRT

The kinetic energy of the satellite when it has been moved and it enters a new circular orbit of radius 2r is K₁/2.

Centripetal force is equal to mass times velocity squared over radius (Fc = mv²/r). Gravity is equal to gravitational constant times the product of masses of two objects over distance squared (Fg = GMm/r²). The centripetal force on the satellite is provided by the gravitational pull by the earth, so Fc = Fg.

Kinetic energy, the energy acquired by a moving object, is equal to one half of a mass times velocity squared (K = mv²/2).

Fc = Fg gives the equation mv²/2 = GMm/2r. As you can see, the kinetic energy K of the satellite is inversely proportional to radius or distance r. Therefore, K decreases by a factor of 2 when r increases by a factor of 2, and K₁/2 = 2r.

The correct mathematical relationship for the two times is Option B: TE = √gM/gE . TM.

Gravity is a natural phenomenon that causes objects with mass to be attracted to one another. It is one of the four fundamental forces in nature and is responsible for the formation and structure of galaxies, stars, and planets. Gravity is experienced as a force pulling objects towards each other. The strength of gravity depends on the distance between two objects, as well as their masses.

This is because the acceleration due to gravity is inversely proportional to the time taken for an object to fall. The equation for this is:
Time = √2*Distance/Acceleration.
Therefore, if we substitute the values for the Moon and Earth in this equation, we get:
TE = √gM/gE . TM

The speed of the proton can be found by using the conservation of mechanical energy. The initial potential energy between the proton and the alpha particle is given by: Ui = (1/4πε) * (2e * e)/y. As the distance between the particles doubles, the final potential energy is given by: Uf = (1/4πε) * (2e * e)/(2y) Using the conservation of mechanical energy, we can write:Ui + Ki = Uf + Kf Where Ki is the initial kinetic energy and Kf is the final kinetic energy. Since the particles are momentarily at rest, Ki = 0. Also, Kf = (1/2) * m * Ur^2. where Ur is the speed of the proton. We can substitute these values into the equation for the conservation of mechanical energy:(1/4πε) * (2e * e)/y = (1/2) * m * Ur^2 + (1/4πε) * (2e * e)/(2y) Solving for Ur, we get: Ur = (e / (m * y)) * √(2/πε).
