Radiant energy is also called responses thermal energy (b)  light energy is correct option.

Radiant energy in physics refers to the energy of electromagnetic and gravitational radiation. Radiant energy is particularly studied via radiometry. Its SI unit for energy is the joule (J). Other than radiometry, electromagnetic energy is denoted by the letters E or W. The phrase is specifically used when electromagnetic radiation is released into the environment by a source. For the human eye, this radiation might be visible or invisible.

Energy included in electromagnetic waves is known as radiant energy. These consist of microwaves, infrared, radio waves, ultraviolet light, and visible light. The random molecular movements of substances store thermal energy, often known as heat energy.

The force acting on a negative charge is in opposition to the direction of the electric field [tex]-2.194 \times 10^{-5}[/tex].

In order for a charge to stay stationary, a weight must be balanced by an electric force that acts in the opposite direction as the weight, with the electric force acting upward.

In a directed electric field, the electric charge particles are subject to a force that is directed in that direction. It can be caused by a charge imbalance, which is when there are more positively charged particles than negatively charged particles in a certain region.

The chipmunk would like to collect twenty acorns. repeating the loop to collect an acorn is called foraging.

Looping is a programming technique that allows a set of instructions to be repeated until a specific condition is met. It is used to execute a set of statements multiple times based on a condition. Loops are used to perform repetitive tasks such as iterating over an array or a collection. They are also used to perform an action on each element in a collection of data. A loop can execute a block of code as long as the specified condition is true. There are two main types of loops: condition-controlled loops and count-controlled loops. Condition-controlled loops execute a set of instructions while a certain condition is true, while count-controlled loops execute a set of instructions a certain number of times. Loops are essential to programming as they allow us to automate repetitive tasks, which can make programs more efficient and easier to maintain.

The magnitude of the force F on the 1.0 nC charge in the figure is the positive charge and force F is 8 x 10^9 N (8 Giga Newtons).

The force F on the 1.0 nC charge in the figure can be calculated using Coulomb's law, which states that the force between two point charges is proportional to the inversely proportional to the square of the distance between the charges and a product of the charges. The magnitude of the force can be calculated using the following formula:

|F| = k x |q1| x |q2| / r^2

where k is the Coulomb constant (9 x 10^9 Nm^2/C^2), q1 and q2 are the charges (in Coulombs), and r is the distance between the charges (in meters).

In this case, q1 = 1.0 nC = 1.0 x 10^-9 C and q2 = -1.0 nC = -1.0 x 10^-9 C (since the charges are opposite and the force is attractive) and r = 0.1 m.

So, the magnitude of the force F can be calculated as:

|F| = k x |q1| x |q2| / r^2 = (9 x 10^9 Nm^2/C^2) x (1.0 x 10^-9 C) x (-1.0 x 10^-9 C) / (0.1 m)^2 = 8 x 10^9 N

The magnitude of the force F is 8 x 10^9 N (8 Giga Newtons)

If there is no heat transferred, the magnitude of work in a system is equal to the change in the internal energy of the system.

If there is no heat transferred, the magnitude of work in a system is equal to the change in the internal energy (ΔU) of the system.

In thermodynamics, the internal energy of a system is the energy that is associated with the random molecular motion of the system. When work is done on or by a system, the internal energy of the system will change.

In the case where no heat is transferred, the first law of thermodynamics states that the change in internal energy (ΔU) of the system is equal to the work done on the system (W):

ΔU = W

So the force you have to apply to break the ropes and accelerate the box with a=1 m/s^2 is 2 + √3 + 1 N

To determine the force FA that must be applied to break the ropes and accelerate the box with a=1 m/s^2, you can use the equation of motion:

F = ma

where F is the net force acting on the box, m is the mass of the box, and a is the acceleration of the box.

We know that the net force acting on the box is equal to the force applied to it minus the forces of tension in the top and side ropes.

So, F = FA - T1 - T2

and the acceleration of the box is 1 m/s^2

Given that,

FA = m×a + T1 + T2

Substitute the given values for m, a, T1 and T2,

FA = 2 kg × 1 m/s² + √3 N + 1 N

FA = 2 kg × 1 m/s² + √3 N + 1 N

                      = 2 + √3 + 1 N

You have travelled 3.375 km in the time it took for the laptop to start up.

Distance travelled is the total amount of distance that a person, vehicle, or object has traveled from one place to another. It is usually measured in miles, kilometers, or other units of measurement. Distance traveled is an important factor when calculating time, speed, or cost.

To calculate how far you have traveled in 27 seconds, we must first calculate the distance traveled in one second. To do that, we need to divide the speed (450.0 km/hr) by 3600, which is the number of seconds in an hour.
   450.0 km/hr / 3600 = 0.125 km/s
Now that we know the distance traveled in one second, we can multiply it by the number of seconds it took for the laptop to start up (27.00 seconds).
0.125 km/s x 27.00 seconds = 3.375 km

The curve of a parabolic path best captures the motion of the piece of cargo.

The parcel moves in a parabolic path, always remaining underneath the aircraft. As the package falls, it encounters a vertical acceleration that alters its vertical velocity. The downward force of gravity on the package is what is causing this vertical acceleration.

If the package's velocity could be roughly compared to projectile motion, then there would be no horizontal acceleration (that is, if the impact of air resistance could be assumed to be insignificant). In the absence of horizontal forces, there would be a constant horizontal velocity. This explains why the package was dropped beneath the plane, as it were.

Sound waves between layers of mass are dampened or diminished using MLV (Mass Loaded Vinyl).

By converting sound waves into heat through the use of a viscoelastic damping compound or MLV, the waves are weakened before they reach the next layer of mass.

Sound can only be stopped by mass. A mass can be made of plywood, drywall, or concrete.

The typical model for wave damping includes a velocity dependent term.

The damping increases when you try to distort the medium more quickly. The amount of damping is significantly influenced by the fluid's viscosity, through which the sound wave is propagating.

Only the bass portion of music is audible when heard from a distance because higher frequency sound dampens in air more quickly.

The wave's amplitude decreases with increasing displacement due to the decrease in energy per unit volume. However, when the wave's energy is dispersed over a huge region, causing it to decay rapidly, a different sort of damping (decrease in energy per unit volume) can be seen.

Gravity's acceleration is constantly downward and constant, however the speed and direction of the acceleration vary. The speed of the ball is zero at its top portion in its trajectory, then it picks up speed again as it descends toward.

Because the acceleration caused by the gravitational force is operating constantly downward at the greatest point when a body was thrown vertically upwards, only that point's velocity is zero. As a result, the velocity is zero due to the acceleration.
