Explanation:

The radiation pressure on the blackened vane is 0.03 N/m².

To determine the radiation pressure on the blackened vane, we can use the formula for radiation pressure:

P = I * A

where:

P is the radiation pressure,

I is the intensity of the electromagnetic wave,

A is the area over which the radiation is incident.

In this case, the intensity is given as 0.30 kW/m², but we need to convert it to watts per square meter (W/m²) for consistency. Recall that 1 kW is equal to 1000 W.

0.30 kW/m² * 1000 W/kW = 300 W/m²

The area over which the radiation is incident on the blackened vane is the surface area of one of the vanes. Since the vanes are square and have dimensions of 1.0 cm by 1.0 cm, the area is:

A = (1.0 cm)² = (0.01 m)² = 0.0001 m²

Now we can calculate the radiation pressure on the blackened vane:

P = I * A = (300 W/m²) * (0.0001 m²) = 0.03 N/m²

Therefore, the radiation pressure on the blackened vane is 0.03 N/m².

The required speed of the the can when the spring is stretches is calculated to be 2.39 m/s.

The magnitude of acceleration of the block is calculated to be 4.12 m/s².

The force constant of the spring is given as k = 76 N/m.

Mass of the beans is given as 5 kg.

The constant horizontal force applied is given as 51 N.

The stretching in the spring is given as 0.4 m.

The expression to calculate speed of the block for the stretch in the spring is,

F x - 1/2 k x² = 1/2 m v²

v = √2 (F x - 1/2 k x²)/m

Putting all the values, we have,

v = √2 (51× 0.4 - 1/2× 76 × (0.4)²)/5 = √2 (20.4 - 6.08)/5 = 2.39 m/s.

Thus, the speed of the can for stretch in the spring is 2.39 m/s.

The relation to calculate the magnitude of acceleration of the block is,

a = (F - k x)/m = (51 - 76× 0.4)/5 = 4.12 m/s²

Thus, the magnitude of acceleration is calculated to be 4.12 m/s².

Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.

Mathematically, the speed of a sound is given by the formula:

Speed = wavelength * frequency

Because wells are deep and a pulley can scoop up the water with a bucket and bring it back to the surface

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.

The net force will be directed downward if the coil is above the magnetic field and upward if the coil is below the magnetic field.

The direction of the net force on the coil depends on the orientation of the coil relative to the magnetic field. Assuming the coil is perpendicular to the magnetic field, the direction of the net force can be determined using the right-hand rule.

If the current is clockwise when viewed from above, the magnetic field produced by the current will be directed out of the page. Using the right-hand rule, if you point your thumb in the direction of the magnetic field and your fingers in the direction of the current, the direction of the net force will be perpendicular to both, and will be in the direction of your palm.

So, the net force will be directed downward if the coil is above the magnetic field and upward if the coil is below the magnetic field.

Answer:

4kg

Explanation:

pressure=50pa

force=200N

Area=?

now,

pressure=force/area

50=200/area

area=200/50

area=4kg

The pressure is the forces acting on a given area. Hence, the area of the surface with a pressure of 50 Pa by a force of 200 N is 4 m².

Force is an external agent acting on a object to deform it or to change its state form motion or rest. Force is a vector quantity and it is characterised by its magnitude and direction. The unit of force is Newton (N).

Pressure is the force applied on unit area. Thus, as the force increases, pressure increases. Pressure can have the units in atm, pa, N/m² etc.

Pressure = Force / area.

Given that force = 200 N

pressure = 50 Pa = 50 N/m²

Therefore, area =  force/pressure

                          = 200 N / 50 Pa

                          = 4 m²

Therefore, the area of the surface is 4 m².

In first scenario, the electric field vector's magnitude would be halved. In second scenario, the electric field vector's magnitude at point P would be doubled.

Charge and charge density are two concepts of electricity, and the following are the differences between them:

Charge: Charge is a property of matter that causes it to experience electrical and magnetic phenomena. It is the fundamental quantity that is responsible for electric phenomena. The SI unit of charge is Coulomb (C), and its symbol is ‘Q’. The charge of an object can be positive or negative or neutral. The charge on an object is measured using an electrostatic balance or an electroscope.

Charge Density: Charge density refers to the amount of charge per unit volume or unit area of a substance. Charge density is the amount of charge per unit length on a given rod. Its SI unit is Coulomb per meter cubed (C/m³). The charge density on an object can be either uniform or non-uniform, i.e., it may be constant over the surface area or may vary throughout it. An electric field vector E is produced by a rod carrying a charge distributed uniformly over the length of the rod. Let the magnitude of the charge be Q. Now, let us consider the following scenarios:

a) How does the field change if rod length is doubled using the same amount of charge?

Assume the point P is still located distance d above the left end of the rod. In this situation, if the rod's length is doubled, the charge will remain the same. Since the charge is distributed uniformly, the charge per unit length would be half of the initial value.

Therefore, the electric field vector's magnitude would be halved.

b) How does the field change if rod length is doubled using the same amount of charge density? Assume the point P is still located distance d above the left end of the rod.In this situation, if the rod's length is doubled, the charge density will remain constant. So, the total charge on the rod will be doubled, and the charge per unit length will remain constant.

As a result, the electric field vector's magnitude at point P would be doubled.

Explanation:

It is given that,

Speed of light, \(v=300 000 000\ m/s=3\times 10^8\ m/s\)

Seconds in 1 year, \(t=32 000 000=32\times 10^6\ s\)

We need to find the distance traveled by light in one year. Speed of an object is given by :

\(v=\dfrac{d}{t}\)

So,

\(d=v\times t\\\\d=3\times 10^8\times 32\times 10^6\\\\d=9.6\times 10^{15}\ m\)

Since,

\(1\ \text{light year}=9.46\times 10^{15}\ m\\\\1\ m=\dfrac{1}{9.46\times 10^{15}}\ \text{ly}\\\\9.6\times 10^{15}\ m=\dfrac{9.6\times 10^{15}}{9.46\times 10^{15}}\\\\d=1.01\ \text{ly}\)

So, the distance covered by light is 1.01 light years.

The amount of force multiplied by the distance moved in the force's direction is known as the work done by a force acting on an item.
