What is the process called when the ice reaches the coast breaks off to form icebergs that are then carried out to sea?

Answer:

B1 = μ_o•I1/2πr

Explanation:

According to the right hand rule, we can say that the magnetic field at the second wire due to the current being carried in first wire is given by;

B1 = μ_o•I1/2πr

Where;

r is distance that separates the two wires

μ_o is a constant known as permeability of free space

I1 is current in wire 1

Torque =   force x distance from point of rotation

Torque is a measure of the turning effect of an applied force about a specific point or axis. It is calculated by multiplying the force applied to an object by the distance from the point of rotation to the point where the force is applied. The greater the force or the longer the distance from the point of rotation, the greater the torque. The unit of torque is typically Newton-meters (N·m) in the International System of Units (SI) or pound-feet (lb·ft) in the imperial system. Torque is essential in various fields such as physics, mechanics, engineering and robotics.

Salt dissolves in water to form saltwater. This kind of change is regarded as a chemical change.

A physical change is a kind of change in which only the physical properties of matter change. In a physical change, neither the composition nor the chemical nature of matter is changed.

A chemical change involves a chemical process that results in the production of new substances. When you dissolve salt in water the sodium chloride dissociates in Na+ and Cl- ions which can be written in the form of a chemical reaction as,

NaCl →  Na+(aq) + Cl-(aq)

Potential energy is the power that a thing possesses as a result of where it is in relation to other objects.

The earth can pull you down through the force of gravity while doing work in the process, being at the top of a stairwell gives you more potential energy than standing at the bottom.

Two magnets have more potential energy when they are held apart than when they are near to one another. They will migrate near each other and begin working if you let them go.

The force acting on the two objects affects the potential energy formula. P.E. = mgh, where m is the mass in kilograms and g is the acceleration due to gravity, is the formula for gravitational force.

The formula for k in terms of the period T and the mass m in spring constant problem is k = 4π²m/T². The formula applies to a spring-mass system.

A spring-mass system is a system where a mass of object is attached at the free end of the spring. The system will perform a simple harmonic motion where the oscillations occur periodically. The period of any moving object in that motion can be counted as follows

T = 2π√(m/k)

Where

Find the formula for the spring constant k in terms of T and m!

We use the formula above to find k.

T = 2π√(m/k)

√(m/k) = T/2π

m/k = (T/2π)²

m/k = T²/4π²

k = 4π²m/T²

Hence, the formula for the spring constant in the spring-mass system is k = 4π²m/T². The answer is A.

the speed of the satellite is 12,880.53 km/h

Explanation:

Given;

radius of the circular orbit, r = 24,600 km

time taken to revolve around Earth, t = 12 hours

The circumference of the satellite is calculated as;

L = 2πr

L = 2π x 24,600 km

The maximum height the diving board can be above the water is 52.5m, so that she does not go any faster than 32 m/s when she enters the water.

To determine the maximum height the diving board can be above the water, we can use the equation of motion for a freely falling object:

v^2 = u^2 + 2as

where

v = final velocity (32 m/s)

u = initial velocity (0 m/s)

a = acceleration due to gravity (-9.8 m/s^2)

s = distance fallen (height of diving board above water)

We can rearrange the equation to find the distance fallen (s)

s = v^2/(-2a) - u^2/2a

substituting the values

s = 32^2/(-2*(-9.8)) = 32^2/19.6 = (1024/19.6) = 52.5 m

She moves at 6.5 m/s as her final speed after running 100 meters.

The velocity change of an object per unit of time is known as acceleration. Amounts of acceleration are measured in meters per second squared (m/s2), the SI unit of acceleration. For instance, due to Earth's gravity, a falling object accelerates at a rate of 9.8 m/s2.

A straight-line motion issue looks something like this. These formulas are used to determine the final velocity:

s = Vo*t + (1/2)*a*at2, and Vf = Vo + at

Where:

Vf = = final speed =?

1.4 m/s is the initial velocity, and 0.20 m/s is the acceleration.

the first equation is changed by:

100 = 1.4t + (1/2)*0.2*t^2\st = 25.388s

The spectral lines of a star are determined by its chemical composition and temperature. These properties determine the number and type of atoms present in the star's atmosphere. Each type of atom has its own unique set of spectral lines, and the temperature of the star determines the energy level of the atoms, which affects the wavelengths of the spectral lines emitted.

The variation with time of the kinetic energy E_k of the ball is that it decreases. This is because gravity is acting against the ball and slowing it down, so the kinetic energy is decreasing as the ball slows down.

When the ball is released, the initial kinetic energy, E_k, is given by the equation: E_k = mgh, where m is the mass of the ball, g is the gravitational acceleration, and h is the initial height of the ball. As the ball rises, its height increases, and the potential energy, U, increases. However, this increase in potential energy is at the expense of kinetic energy, so the kinetic energy decreases as the ball rises.  

When the ball reaches its maximum height, its kinetic energy is zero as it is at rest. As the ball then begins to fall, its potential energy decreases, and its kinetic energy increases. This is because the ball is falling under the action of gravity, and thus its kinetic energy increases as it accelerates downwards.  Overall, the kinetic energy of the ball decreases as it rises and increases as it falls.

This is due to the conservation of energy, which states that the total energy of a system remains constant. As the potential energy increases, the kinetic energy decreases, and vice versa.

The correct option is A, B, and C. A block resting on a slope is Weight, static friction, and Normal force.

Static friction is a force that continues an item at relaxation. Static friction definition can be written as: The friction skilled while individuals try to move a desk-bound object on a surface, without surely triggering any relative movement between the frame and the surface on which it's miles.

Static friction is a form of friction force that acts on a body when there's no relative motion between the object and the surface. So, it can act even if the frame is in motion however there should be no relative motion.

A pressure acting on an item is said to be a static force if it no longer exchanges the scale, function, or route of that precise object. The pressure implemented to a structure acts as a load to that precise structure, that is why static force is likewise called a static load.

The objects must be of opposite charge because the electric force of attraction between them increases when they are released and free to move.

This means that the electric force must be a repulsive force that pushes the objects away from each other. Opposite charges attract and as charges repel, the objects must be of opposite charge for the electric force to increase when the objects are released and free to move.

Therefore when two small objects carry the same amount of charge, the magnitude of the electric force exerted by one object on the other is 0.10 N when they are held 30 mm apart. If the force magnitude increases when the objects are released and free to move, then we can say that they are opposite charges.

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.
