If an object accelerates from rest, the velocity after 2.1 s, if it has a constant acceleration of 9.8 m/s² is 43.218 m/s².

To find the velocity, the given values are,

Time = 2.1 seconds

Acceleration = 9.8 m/s².

Acceleration can be defined as the rate of change of the velocity of an item with appreciation to time. Accelerations can be vector portions. The orientation of an item's acceleration is given by the orientation of the net pressure appearing on that object.

The acceleration will remain the same at 9.8 m/s². as under free fall conditions acceleration due to gravity remains constant.

Calculation:-

V = U + at

V = 0 + 9.8 × (2.1)²

The procedure and data analysis method that a student used to determine the index of refraction nglass is an experiment where they shine a ray of light from air into the glass.

One possible procedure could involve measuring the angle of incidence and the angle of refraction using a protractor or other measuring tool. The student could vary the angle of incidence and measure the corresponding angle of refraction to obtain a range of data points. To analyze the data, the student could plot the sine of the angle of incidence against the sine of the angle of refraction. The slope of this line would be equal to the reciprocal of the index of refraction of the glass. The student could then use this slope to calculate the index of refraction nglass of the glass.

Another method that could be used to analyze the data is to apply Snell's Law, which states that the ratio of the sines of the angle of incidence and the angle of refraction is equal to the ratio of the indices of refraction of the two media. By measuring the angles of incidence and refraction, the student could plug these values into Snell's Law to calculate the index of refraction nglass of the glass.

Since different currents are passing through the resistors, then the resistors are most probably connected in parallel. This also means that the same voltage will pass across them.

Using Ohm's law, the voltage across a resistor in a circuit is given by;

V = I(R + r)            -----------(i)

For the 1ohm resistor, the voltage across it is given by;

Where;

I = current passing through the 1 ohm resistor = 0.6A

R = resistance of the 1 ohm resistor = 1Ω

r = internal resistance of the cell = r

Substitute these values into equation (i) as follows;

V = 0.6(1 + r)                 -------------------(ii)

For the 4.0ohm resistor, the voltage across it is given by;

Where;

I = current passing through the 4.0 ohms resistor = 0.2A

R = resistance of the 4.0 ohms resistor = 4.0Ω

r = internal resistance of the cell = r

Substitute these values into equation (i) as follows;

V = 0.2(4.0 + r)                 -------------------(iii)

Now solve equations (ii) and (iii) simultaneously;

V = 0.6(1 + r)

V = 0.2(4.0 + r)

Substitute the value of V in equation (ii) into equation (iii). Therefore, we have;

0.6(1 + r) = 0.2(4.0 + r)

Solve for r

0.6 + 0.6r = 0.8 + 0.2r

0.6r - 0.2r = 0.8 - 0.6

0.4r = 0.2

r = \(\frac{0.2}{0.4}\)

r = 0.5

Therefore, the internal resistance of the cell is 0.5Ω

The fourth-order polynomial in the Lagrange form that passes through the points is P(x) = 2330. The power at a wind speed of 26 mph is 2330 W.

To find the fourth-order polynomial in the Lagrange form that passes through the given points, use Lagrange interpolation. The Lagrange polynomial is defined as:

P(x) = Σ [yi × Li(x)]

where P(x) = polynomial function, yi = corresponding y-value, and Li(x) = Lagrange basis polynomial.

The Lagrange basis polynomials are calculated as:

Li(x) = Π [(x - xj) / (xi - xj)], for i ≠ j

where xi and xj = x-values of the given points.

Calculate the Lagrange basis polynomials for the given points:

For x = 14:

L0(14) = (14 - 22) × (14 - 30) × (14 - 38) × (14 - 46) / (14 - 22) × (14 - 30) × (14 - 38) × (14 - 46) = 1

For x = 22:

L1(22) = (22 - 14) × (22 - 30) × (22 - 38) × (22 - 46) / (22 - 14) × (22 - 30) × (22 - 38) × (22 - 46) = 1

For x = 30:

L2(30) = (30 - 14) × (30 - 22) × (30 - 38) × (30 - 46) / (30 - 14) × (30 - 22) × (30 - 38) × (30 - 46) = 1

For x = 38:

L3(38) = (38 - 14) × (38 - 22) × (38 - 30) × (38 - 46) / (38 - 14) × (38 - 22) × (38 - 30) × (38 - 46) = 1

For x = 46:

L4(46) = (46 - 14) × (46 - 22) × (46 - 30) × (46 - 38) / (46 - 14) × (46 - 22) × (46 - 30) × (46 - 38) = 1

Now, calculate the polynomial function P(x) using the Lagrange form:

P(x) = 320 × L0(x) + 490 × L1(x) + 540 × L2(x) + 500 × L3(x) + 480 × L4(x)

Simplifying the expression:

P(x) = 320 + 490 + 540 + 500 + 480

P(x) = 2330

Therefore, the fourth-order polynomial in the Lagrange form that passes through the given points is:

P(x) = 2330

To calculate the power at a wind speed of 26 mph, substitute x = 26 into the polynomial:

P(26) = 2330

The power at a wind speed of 26 mph is 2330 W.

Answer:

monochromator

Explanation:

In this scenario, a block of mass m starts to slide at an angle θ with the horizontal. At the same time, the box is stopped from rotating. As the block slides a distance d, it hits a spring with a force constant k and compresses the spring by a distance x before coming to rest. The relationship between the given quantities can be explained using principles of energy conservation and Hooke's law.

When the block slides down the inclined plane, its potential energy is converted into kinetic energy. As it hits the spring, the kinetic energy is transferred to the spring, causing it to compress. At this point, the block comes to rest, and all the initial kinetic energy is stored as potential energy in the compressed spring.

The potential energy stored in the spring can be calculated using the equation:

PE_spring = (1/2)kx²

This potential energy comes from the initial potential energy of the block due to its height above the ground:

PE_block = mgh = mgd sin(θ)

By equating the potential energies, we have:

(1/2)kx² = mgd sin(θ)

From Hooke's law, we know that the force exerted by the spring is given by:

F_spring = kx

The force exerted by the spring is also equal to the weight component of the block along the incline:

F_spring = mg sin(θ)

By equating these forces, we get:

kx = mg sin(θ)

Combining this equation with  previous equation, we can solve for the compression distance x:

(1/2)kx² = (kx)(d sin(θ))

Simplifying, we find:

x = 2d sin(θ)

Therefore, in terms of the given quantities, the compression distance x of the spring is given by x = 2d sin(θ). This relationship shows that the compression distance is directly proportional to the distance traveled down the incline (d) and the sine of the angle of inclination (θ).

Longitudinal waves are those waves which move in the same direction as of the particle of the medium. That means, The Particles of the medium move forward and backward just like the Wave move forward so they propagate in the same direction.

The Sound wave is the example of the longitudinal wave as it propagates in  the same direction as the particle do.

Transverse wave are those waves which propagate in the perpendicular direction as of the particle of the medium. That means, The particle moves up and down but the wave propagate in forward direction. So they dont move in similar direction but perpendicular.

Water wave is the perfect example of the transverse wave as you can see that water particles form crest(Up the midline) and trough(down the midline) i.e. upward and downward movement but the water actually moves forward in direction.

The magnitude of the vector B is 42 units in the negative Y- direction, if it is added to a vector A of 24 units and giving resultant vector of 18 units.

Vector A magnitude, = 24 units

As it is perpendicular the x-axis so, x = 0

So the co-ordinate of the vector A head will be = (0, 24)

Resultant vector magnitude, = -18 units

As it is perpendicular the x-axis so, x = 0

So the co-ordinate of the vector A head will be, R = (0, -18)

A + B = R

B = R - A

B = -18 - 24

B = -42

The coordinate of the vector B, = (0, -42)

A negative sign indicates that the direction of the vector will be along the y-negative axis.

One of Newton's laws is the law of inertia, which states that an object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an external force.                                                                                                                          

Airbags and seatbelts are important in saving lives because they act as the external force that can stop the motion of an object  in the event of a collision. Without these safety measures, the body would continue to move forward at the same speed as the vehicle, causing serious injuries or even death upon impact. By quickly inflating and creating a cushion, airbags reduce the force of impact and prevent the head and chest from hitting hard surfaces inside the car. Seatbelts, on the other hand, prevent passengers from being thrown out of the car or hitting the dashboard or windshield.
Seatbelts restrain this motion, while airbags provide a cushion to reduce the impact force. Both safety features work together to prevent injuries and save lives.
