The strength of a magnet is determined by various factors such as the material used, shape and size of the magnet, distance between the magnet and the object it attracts, temperature, and external magnetic fields. The type of material used greatly affects its strength, with materials like neodymium and samarium cobalt being some of the strongest magnets available. Shape and size of the magnet also play a role, with larger magnets having greater strength. The distance between the magnet and the object it attracts affects the strength of attraction, as does temperature.

If a ship weighs 52,000 tons and is in isostatic equilibrium when 6,000 tons of cargo is added, the total mass of water that will be displaced by the ship after the cargo is added is (M)= 58000 tons.

The weight is term that means that by how much gravitational force earth going to attract that object. It can be shown easily, W=mg. It is a vector quantity. It can be measured in kg.m/s²

To calculate the mass we are using the formula,

M=m₁+m₂

Here we are given,

m₁= The weight of the ship according to the question. =52,000 tons.

m₂= The weight of cargo that is added on the ship. = 6000 tons.

We have to calculate the total mass of water that will be displaced by the ship after the cargo is added is =M tons.

Now we put the values in above equation, we get

M=m₁+m₂

Or, M= 52000+6000

Or, M= 58000 tons.

So we can say that, the total mass of water that will be displaced by the ship after the cargo is added is (M)= 58000 tons.

When two mirrors are placed facing each other, it creates a phenomenon known as "mirror reflection" or "infinite reflection." This occurs as the light reflects back and forth between the mirrors, creating multiple reflections that appear to stretch infinitely into the distance.

The reflection continues on and on until it becomes too small to see. In this way, a person sees many reflections of themselves, and each reflection is smaller than the previous one. This is called an infinity mirror or a mirror tunnel.An infinity mirror is a visual illusion that looks like the mirror has no end. It is accomplished by placing a mirror in front of another and allowing a small amount of space between the two.

The farthest away a target could be hit by a shell is approximately 1000 yards (rounded to the nearest whole number).

To solve the problem, we need to find the total distance that the shell can travel before it bursts.

The distance that the shell can travel is:

distance = rate × time

We are given that the shell can travel 500 yards in 1.5 seconds, so its speed is:

rate = distance ÷ time = 500 yards ÷ 1.5 seconds = 333.33 yards/second

Now we need to take into account the time it takes for the fuse to go off. Since it takes 3 seconds for the fuse to go off, the shell will have traveled:

distance = rate × time = 333.33 yards/second × (1.5 seconds + 3 seconds) = 999.99 yards

We can model this as an infinite square well in which the particle's potential energy inside the box is zero and the potential energy outside is infinite. Therefore, the particle's quantum number is 4.86 × 10⁻²

The expression of wave function for a particle in one dimensional box is given as

φ(x) = ( √2/L ) sin ( nπx/L )

now we input our given figures, the limit of the particle to find it within the center of the box is

xₓ = L/2 + 20% of L/2

xₓ = L/2 + (0.2)L/2

xₓ = 3L/5

And the lower limit is,

x₁ = L/2 - 20% of L/2

x₁ = L/2 - (0.2) L/2

x₁ = 2L / 5

The expression for the probability of finding the particle within the center of the box is

P = ∫ˣₓ₁ ║φ(x)║² dx

P = ∫ ³L/⁵ ₂L/₅║(√2/L) sin ( nπx/L)║²dx

= 2/L ( ∫ ³L/⁵ ₂L/₅║sin ( nπx/L)║²dx

= 2/L ( ∫ ³L/⁵ ₂L/₅ (( 1 - cos ( 2πn x/L)/2) dx)

The particle is in its first excited state, then

n =2

Then calculate  the particle's quantum number as follows;

= 2/L ( ∫ ³L/⁵ ₂L/₅ (( 1 - cos ( 2π(2)x/L)/(2)) dx)

= 1/L ( ∫ ³L/⁵ ₂L/₅ (( 1 - cos ( 4πx/L)/2) dx

= 1/L ( x - (L/4π)sin (4πx/L)) ³L/⁵ ₂L/₅

= 1/L ((3L/5) - (L/4π) sin (( 4π(3L/5)/L)) - (( 2L/5) - (L/4π)sin  ( 4π(2L/5)/L)))

= 1/L ( L/5 + L/4π (sin(8π/5) - sin ( 12π/5)))

Use the trigonometric formula to solve the above equation

Sin A – sin B = 2sin ( A-B/2) cos (A+B/2)

Calculate the particle's quantum number as follows

P = 1/L ( L/5 + L/4π (sin(8π/5) - sin ( 12π/5)))

= 1/5 + 1/4π ( 2sin( (8π/5 -12π/5 ) / 2 ) cos ( (8π/5 + 12π/5) / 2 ))

= 1/5 + 1/2π ( -sin(2π/5) cos2π

= 1/5 - 1/2π ( sin (2π/5)(1))

Power in the first second:

P1 = dW1/dt,

= W2 - W1, (as the time interval is 1 second).

Power in the second second:

P2 = dW2/dt,

= W3 - W2, (as the time interval is 1 second).

Power in the third second:

P3 = dW3/dt,

= 0, (as we don't have data for the fourth second).

Let's assume the force acting on the body is constant throughout the time period.

Work done by a force (W) is given by the formula:

W = F * d * cos(theta),

where:

F is the magnitude of the force (in newtons, N),

d is the displacement of the body (in meters, m),

theta is the angle between the force and displacement vectors (if they are not in the same direction).

Since the body is initially at rest, we'll assume the displacement occurs in a straight line, so theta = 0 degrees and cos(theta) = 1.

To calculate the work done in the first second, we need to know the displacement during that time. Let's assume the body accelerates uniformly.

Using the equation of motion:

s = ut + (1/2)at^2,

where:

s is the displacement (unknown),

u is the initial velocity (0 m/s, as the body is at rest),

a is the acceleration (F/m, where m is the mass of the body in kg),

t is the time (1 s, for the first second).

Rearranging the equation, we get:

s = (1/2)at^2.

Since the initial velocity is zero, the equation simplifies to:

s = (1/2)(F/m)t^2.

Now, let's calculate the work done in the first second:

W1 = F * s1,

= F * [(1/2)(F/m)(1s)^2],

= F^2/(2m).

The work done in the second second can be calculated using the same approach but with a time of 2 seconds:

s2 = (1/2)(F/m)(2s)^2,

= 2^2(F^2/m),

= 4F^2/m.

W2 = F * s2,

= F * (4F^2/m),

= 4F^3/m.

For the third second:

s3 = (1/2)(F/m)(3s)^2,

= 9F^2/m.

W3 = F * s3,

= F * (9F^2/m),

= 9F^3/m.

Now, let's calculate the instantaneous power due to the force. Power (P) is defined as the rate at which work is done, given by the formula:

P = dW/dt,

where dW is the differential work done in a small time interval dt.

Since we know the work done in each second, we can calculate the instantaneous power as the rate of change of work with respect to time.

Power in the first second:

P1 = dW1/dt,

= W2 - W1, (as the time interval is 1 second).

Power in the second second:

P2 = dW2/dt,

= W3 - W2, (as the time interval is 1 second).

Power in the third second:

P3 = dW3/dt,

= 0, (as we don't have data for the fourth second).

Keep in mind that this calculation assumes the force remains constant throughout the time period and the body's mass doesn't change.

The direction of the impulse that the bat delivers to the ball is in the direction of motion of the ball.

The direction of the impulse that the bat delivers to the ball is in the direction of motion of the ball. This is due to the conservation of momentum. The impulse is the change in momentum of an object, and it is equal to the force applied multiplied by the time it is applied.

The conservation of momentum states that the total momentum of a system remains constant if there are no external forces acting on the system. In the case of a bat hitting a ball, the system includes both the bat and the ball.

When the bat hits the ball, the bat applies a force to the ball that changes the momentum of the ball. The impulse of the bat on the ball is in the direction of the motion of the ball, which is usually towards the fielders or outfielders.

This is due to the fact that the ball has to move in the direction of the force applied by the bat.

Therefore, the direction of the impulse that the bat delivers to the ball is in the direction of motion of the ball. The impulse can be expressed in units of Newton seconds (Ns), and it is equal to the force applied multiplied by the time it is applied.

if   ε = 0 we have a circumference

In the diagram presented the orbit of the comet is an ellipse a> b

          ε=\(\sqrt{1- x} \\ x = (\frac{b}{a} )^2\)

if we expand in series

             ε = 1 - x/2  

             ε=  \(1 - \frac{1}{2} \ (\frac{ b}{a} )^2\)

if we neglect the non-linear terms

            ε = 1

Earth's orbit is a small ellipse

             b / a = 149 10⁶ / 151 10⁶

             b / a = 0.98675

             ε = \(\sqrt{1- 0.98675^2}\)

given :

masses of both the balls are same

using conservation of momentum

m1u1 + m2u2 = m1v1 + m2v2
