Answer:

I believe that Law is called the Law of Conservation of Energy (Thermodynamics)

Explanation:

The force F1 is equal and opposite to the downward force thus, F1 is equal to 60 N. The force F2 is inclined to 30 ° from leftward force and it is equal to 38.97 N in magnitude.

Force is an external agent acting on a body to deform it or to change its state of motion or rest. Force is a vector quantity and it is characterised by its magnitude and direction.

If two forces acting on a body from the same directions, then the net force will be the sum of these two forces. If they are acting from opposite directions, they will cancel each other in magnitude.

The force F1 is equal and opposite to the force acting downward. Thus its magnitude is 60 N. The force F2 is inclined to 30 ° from horizontal direction.

F2 = 45 cos 30 = 38.9 N.

The statement is false. Granulation is not the most obvious proof of solar convective energy transport.

Granulation refers to the pattern of small, bright cells on the surface of the Sun, which are caused by convective motions in the outer layers of the solar atmosphere. While granulation is indeed evidence of convective energy transport within the Sun, it is not the most obvious proof. The most evident proof of solar convective energy transport is the overall brightness of the Sun itself. The Sun emits a vast amount of energy, and this energy is generated through nuclear fusion in its core. The energy then travels through the radiative zone and is finally transported to the surface by convective motions in the outer layers, including the granulation pattern.

While granulation provides a visible manifestation of these convective motions, other phenomena such as sunspots, solar flares, and coronal loops also provide evidence of convective energy transport and other dynamic processes occurring in the Sun. Therefore, while granulation is an observable consequence of solar convection, it is not the most prominent or obvious proof of convective energy transport in the Sun.

8.20 × 10¹⁶ MeV of energy is emitted during the fission of one 235U nucleus.

Energy can only be transformed from one form to another; it cannot be created or destroyed.

When a nucleus of 235U is bombarded by a neutron, it absorbs the neutron and becomes unstable. This causes the nucleus to split (fission) into two smaller nuclei, releasing energy in the form of gamma rays, kinetic energy of the fission fragments, and neutrons. The total energy released in a fission event can be calculated using Einstein's famous equation E=mc², where E is the energy, m is the mass defect (the difference in mass between the initial nucleus and the fission products), and c is the speed of light.

For a single fission event of 235U, on average, the fission products have a combined mass of about 235 atomic mass units (AMU), while the mass of the neutron is about 1 AMU. This means that the mass defect for one fission event is:

Δm = (235 + 1) AMU - 235 AMU = 1 AMU

Using the conversion factor 1 amu = 931.5 MeV/c², we can convert the mass defect to energy:

ΔE = Δm × c² = 1 AMU × (931.5 MeV/c²) × (3.00 × 10⁸ m/s)² = 8.20 × 10² MeV

Therefore, the energy released when one 235U nucleus undergoes fission is 8.20 × 10¹⁶ MeV.

For our delicate measurement equipment to continue to operate accurately, gaussmeter calibration is necessary. In order to achieve this, we compare the instrument to one with a standard or greater accuracy. Then, if there is a deviation from the actual reading, we find it and fix it.

By delivering a reverse field to the magnet that is strong enough to bring the output (of flux) down to a reasonable level, magnetic calibration is accomplished.

Using a Tesla or Gauss metre, one may determine the intensity of a magnet's magnetic field. Many people who utilise magnets today possess their own Gauss metres and decide what magnetic field strengths are acceptable. The magnet analyzer will measure the magnetic field strength for multi-polar magnets.

The Hall Effect in semiconductors is the basis for how a digital Gauss metre functions. A voltage is created at a right angle to the current route when a semiconductor with current flowing in one direction is introduced perpendicular to a magnetic field.

Using the given values, we find: a = (6378.137 + 300)/2 / (1 - 1.5) = 5529.77 km , r = 5529.77 km * (1 - 1.5) = -1843.26 km

To calculate the position and velocity vectors of the spacecraft at perigee, we need to convert the given orbital elements to Cartesian coordinates in the perifocal reference frame, and then transform them to the geocentric equatorial frame.

First, we calculate the semi-major axis of the orbit using the vis-viva equation:

\(v^2\) = GM(2/r - 1/a)

where v is the velocity at perigee, G is the gravitational constant, M is the mass of the Earth, r is the radius of the Earth plus the perigee altitude, and a is the semi-major axis. Solving for a, we get:

a =\(r/(2 - r v^2/GM)\)

At perigee, the velocity is tangent to the orbit, so the radial component of the velocity is zero and the magnitude of the velocity is given by:

v = √(GM/r) * √((1+e)/(1-e))

where e is the eccentricity of the orbit. Substituting this expression into the equation for the semi-major axis, we can solve for r:

a = r/(2 - r (GM/r) * (1+e)/(1-e))

a = r/2(1 - e)

r = a(1 - e)

Using the given values, we find:

a = (6378.137 + 300)/2 / (1 - 1.5) = 5529.77 km

Elastic potential energy is initially at rest, making it move.

Elastic potential energy is what causes a ball to bounce or rebound because it is transformed into kinetic energy and used to raise the ball back up. However, because some of the ball's energy was transferred to the ground or changed into sound (in the noise it makes upon impact) and heat energy, the ball won't go as high as it did at first (friction with the table). Additionally, even though we cannot see it, the ball alters once it strikes the ground or a table, energy is needed to take shape for a brief period of time.

Because of this, each bounce has a slightly lower height than the one before it. The ball has some kinetic energy when it hits the floor, but some of it is changed, so it loses some of it each time it bounces. After a few bounces, the ball has so little kinetic energy remaining that it stops bouncing.

Thus the correct answer is option A.

The force exerted by the tennis player on the tennis ball is 4 Newtons (N).

To determine the force exerted by the tennis player on the tennis ball, we can use Newton's second law of motion, which states that force (F) is equal to the mass (m) of an object multiplied by its acceleration (a).

Mass of the tennis ball (m) = 0.25 kg

Acceleration (a) = 16 m/s^2

Using Newton's second law, we can calculate the force (F):

F = m * a

F = 0.25 kg * 16 m/s^2

F = 4 kg*m/s^2

This means that the tennis player applied a force of 4 N to the tennis ball to achieve an acceleration of 16 m/s^2. The force applied is in the same direction as the acceleration, which is responsible for the ball's movement over the net. It's important to note that this force is exerted by the player on the ball and does not include any external factors such as air resistance or friction.

The force on charge q2 is approximately 179.751 N.

The force between two point charges can be found using Coulomb's law:
F = (k * q1 * q2) / r^2
Where F is the force between the charges, k is the Coulomb constant (8.98755 × 10^9 N·m^2/C^2), q1 and q2 are the magnitudes of the charges in Coulombs, and r is the distance between the charges in meters.
In this case, q1 = 2 µC and q2 = 10 µC. The distance between the charges is the distance between the origin and the point on the x-axis where q2 is located, which is 10 m.
So, we can calculate the force on q2 as follows:
F = (8.98755 × 10^9 N·m^2/C^2) * (2 µC) * (10 µC) / (10 m)^2
F = (8.98755 × 10^9 * 2 * 10) / 100
F = 1.79751 × 10^9 / 100
F = 1.79751 × 10^7 N
The force on charge q2, we can use Coulomb's Law. Coulomb's Law states that the force (F) between two point charges is directly proportional to the product of their charges (q1 and q2) and inversely proportional to the square of the distance (r) between them:
F = k * (q1 * q2) / r^2
In this case, q1 = 2 µC, q2 = 10 µC, r = 10 m, and the Coulomb constant (k) is 8.98755 × 10^9 N·m^2/C^2.
The charges to Coulombs: q1 = 2 × 10^-6 C and q2 = 10 × 10^-6 C.
F = (8.98755 × 10^9 N·m^2/C^2) * ((2 × 10^-6 C) * (10 × 10^-6 C)) / (10 m)^2
F = (8.98755 × 10^9 N·m^2/C^2) * (2 × 10^-5 C^2) / (100 m^2)

A 9-volt battery will take 18 j of work to move 2 coulombs of charge from the negative terminal to the positive terminal of a battery.

To determine the work required to move 2 coulombs of charge from the negative terminal to the positive terminal of a 9-volt battery, we can use the formula:

Work (W) = Electric potential difference (V) × Charge (Q)

Given:

Electric potential difference (V) = 9 volts

Charge (Q) = 2 coulombs

Substituting these values into the formula:

Work (W) = 9 volts × 2 coulombs

W = 18 joules

Therefore, it would take 18 joules of work to move 2 coulombs of charge from the negative terminal to the positive terminal of a 9-volt battery.

This indicates the energy required to overcome the potential difference provided by the battery and transfer the charge against the electric field. The work done is proportional to the product of the charge and the potential difference, in this case, resulting in 18 joules of work.

The angle θ is approximately 0.688°, and the angle θ' is approximately 1.988°.

To determine the angles θ and θ' in the given scenario, we can use Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the media involved. Snell's Law can be stated as follows:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Where:

n₁ is the refractive index of the medium of incidence (in this case, air with a refractive index close to 1),

θ₁ is the angle of incidence,

n₂ is the refractive index of the medium of refraction (in this case, linseed oil with a refractive index of 1.48), and

θ₂ is the angle of refraction.

Let's solve for the unknown angles θ and θ' using the given information.

Given:

Angle of incidence θ = 1°

Refractive index of linseed oil n₂ = 1.48

We need to find the angle of refraction θ₂.

Using Snell's Law, we have:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Since the refractive index of air (n₁) is approximately 1, we can simplify the equation to:

sin(θ₁) = n₂ * sin(θ₂)

Plugging in the values:

sin(1°) = 1.48 * sin(θ₂)

We can now solve for θ₂:

θ₂ = arcsin(sin(1°) / 1.48)

Calculating this value, we find:

θ₂ ≈ 0.688°

Now, let's determine the angle θ'.

Given:

Angle of refraction θ₂ = 0.688°

Refractive index of linseed oil n₂ = 1.48

We need to find the angle of incidence θ'.

Using Snell's Law, we have:

n₂ * sin(θ₂) = n₁ * sin(θ')

Since the refractive index of air (n₁) is approximately 1, we can simplify the equation to:

n₂ * sin(θ₂) = sin(θ')

Plugging in the values:

1.48 * sin(0.688°) = sin(θ')

Solving for θ', we find:

θ' = arcsin(1.48 * sin(0.688°))

Calculating this value, we get:

θ' ≈ 1.988°

Therefore, the angle θ is approximately 0.688°, and the angle θ' is approximately 1.988°.
