Explanation:

they rebounce, therefore it's elastic.

The length of nylon rope from which a mountain climber is suspended has a force constant of 1.15 ✕ 104 N/m.

Spring constant is the common name for the force constant. Hooke's law states that F=-kx. k=N/m is used to replace units in the equation where F is force, x is displacement, and k is force constant (spring constant) to determine the SI unit of force constant (spring constant).

The slope (gradient) of the graph equals the force constant. The proportionality constant, or k, is also known as the force constant in physics. A spring that is more rigid will have a higher value for k. The graph is no longer a straight line beyond point A since the gradient has changed and the formula F = Kx is no longer valid.

Maximum speed is at equilibrium where:

F = kx ⇒x =F/k

Now, F x=1/2mv²+1/2kx²

Solving we get,

V=F/√mk=Vmax

The missing forces in the diagram given are: A = 50 N; B = 200 N; C = 1100 N; D = 20 N; E = 300 N; F = 0 N; G = 50 N and H = 0 N.

In physics and engineering, a resultant force is a single force and associated torque obtained by combining a system of forces and torques acting on a rigid body by vector addition. The characteristic of a resultant force or force-torque is that it has the same effect on a rigid body as the original force system. The resulting forces on the body are calculated and visualized by computational analysis or (for sufficiently simple systems) by free-body diagrams.

For A and B:

Since net force is zero the applied forces in all four direction will be equal but opposite.

So A will be 50 N and B will be 200 N.

For C:

The net force is 900 N;

C = 900 + 200

C = 1100 N

For D and E:

The net force is 60 N left; this means the net upward or downward force acting on the object is zero.

So E = 300 N

D = 80 - 60

D = 20 N

For F, G and H:

The net force is 30 N right; this means the net upward or downward force acting on the object is zero.

So F and H will be zero.

G = 20 + 30

G = 50 N

Explanation:

The upward acceleration of an object can be calculated using the formula:

[tex]a = F / m[/tex]

where:

a is the acceleration of the object (in meters per second squared)

F is the force acting on the object (in newtons)

m is the mass of the object (in kilograms)

So in this case, we have:

[tex]a = 11000 N / 5250 kg = 2.09 m/s^2[/tex]

This is the upward acceleration of the helicopter when a force of 11000 N is acting on it.

It's unknown where the term "p" for momentum first appeared. Since m had already been used for "mass," it has been proposed that the p may have been derived from the Latin petere or from "progress".

The letter "I" would cause a misunderstanding between inertia and moment of inertia. The French and Germans selected "p" for momentum because of this.

The formula p = mv can be used to compute momentum, where p stands for momentum, m for mass, and v for velocity. The usage of the letter p to represent momentum has various benefits. First off, it would be unclear to use m for momentum because m stand for mass.

The new force of attraction is 324N if the distance between the centres of the two objects is reduced by a factor of 3e.

The equation for the force of gravitational attraction between two objects is: F = G*(m1*m2)/r^2 Where F is the force of attraction, G is the gravitational constant (6.67 x 10^-11 Nm^2/kg^2), m1 and m2 are the masses of the two objects, and r is the distance between their centers. If the distance between the two objects' centers is decreased by a factor of three, the new force of attraction will be: F' = G*(m1*m2)/(r/3)^2The ratio of the new force of attraction to the original force of attraction is:

F'/F = (r/3)^2 If we substitute in the original force of attraction, we have:

F'/36 = (r/3)^2 = F' = 36 * (r/3)^2

Answer: B

Explanation:

Free fall -> constant acceleration of g = 9.81ms-1

Constant acceleration -> velocity increases at a constant rate (increases proportionally with time)

Math behind it:

* Velocity is the integration of acceleration, likewise acceleration is the differentiation of velocity. Integrating a constant value gives linearly increasing function in terms of x. (integrating with respect to x)

Hence, graph B shows the trend that velocity increases at a constant rate.

Graph A - Velocity decreases linearly

Graph C - Also decreases nonlinearly

Graph D - Not possible scenario. Velocity approaches infinity.

The linear diameter of an object with an angular diameter of 25 arcseconds and a distance of 65 km will be 0.067 meters.

Linear Diameter = (Angular Diameter ×Distance) / 206264.81.

In this case, the linear diameter would be 0.067 meters.

To put this into context, a linear diameter of 0.067 meters is approximately equal to 6.7 centimeters, or 2.6 inches. To put this another way, it is approximately the size of a large grape. As such, it is incredibly small and would be difficult to see with the  eye.

Explanation:

In the definition of weight, W = mg, the mass m refers to an inertial mass.

The velocity of the particle at t=0 is zero because the particle is in rest position and did not moving at any of the instance or travelling at an uniform speed through out the whole journey or yet did not start from the source point.

Velocity is the rate of change of velocity. At any point on a trajectory, the magnitude of the velocity is given by the rate of change of velocity in both magnitude and direction. Velocity of the body that we can consider is the increasing value of the velocity of any object at a constant rate and that of we can calculate. Hence by the primary information that we have we can formerly consider that the velocity which is acting on the particle at t=0 is zero because the particle is in rest position and did not moving at any of the instance or travelling at an uniform speed through out the whole journey or yet did not start from the source point.

An X-ray tube is used to create X-rays. When quickly traveling electrons strike a metal object, they are released. Wilhelm Conrad Roentgen made the X-ray discovery in 1895.

The flesh can be penetrated by long wavelength X-rays, but not the bones. They assist doctors in viewing the inside of the body through X-ray imagery. They are helpful in identifying malignancies and bone fractures.

Even metals can be penetrated by short wavelength X-rays. They are applied in industry to check for flaws in welded joints.

All X-rays pose a risk because they have the potential to harm the body's healthy, functioning cells.

This is why exposure to X-rays on a regular basis should be avoided. Body tissues can be harmed by excessive X-ray exposure, which can also lead to cancer.

To create images of the body, its organs, and other internal structures for diagnostic purposes, X-rays use external radiation. A "negative" type image is created when X-rays penetrate human structures and land on specially treated plates (similar to camera film) or digital media (the more solid a structure is, the whiter it appears on the film).

Different bodily components permit various amounts of the X-ray beams to pass through when the body is exposed to X-rays. The majority of the X-ray energy can pass through soft tissues in the body, including blood, skin, fat, and muscle, making them look dark gray on film or digital media. Few X-rays can penetrate dense soft tissue like a bone or a tumor.

The statement is false. The capacitor doesn't charge Q exponentially decays to zero when the RELAY is thrown to position N.O.

As a capacitor charges, its voltage also rise.

V = Q/C

where Q = charge, V = voltage and C = capacitance

If the circuit contains a battery, a resistor and a capacitor all connected in series, then the following are true.

The battery voltage is fixed. And the capacitor voltage is rising. This clearly means that the current through the resistor is dropping.

I = (Vbatt - Vcap)/R

Since the current is dropping, then the rate at which charge is deposited on one plate and removed from the other one continuously drops.

So the charging of the capacitor also slows down because of the rising voltage.

But here the rise in the voltage is slowing down because of the rate of charges that are accumulating and leaving continuously is slowing down.

The slower rise in voltage causes a further slowing in the rate of charge movement which further slows down the rise in voltage which causes an even slower rate of charge movement.

A capacitor is referred as an electrical device which stores electrical charge when it is connected across the source of potential difference.

The total charge that the capacitor can be stored when it is placed across a potential V is given by
