Starting from rest on a circular track with a radius of 300 m and a constant tangential acceleration of 0.75 m/s², the car will travel a distance of approximately 0.2119 meters or 21.19 centimeters in 0.75 seconds.

To determine the distance traveled and the time elapsed by the car starting from rest on a circular track with a radius of 300 m and a constant tangential acceleration of 0.75 m/s², we can use the equations of circular motion.

The tangential acceleration is the rate of change of tangential velocity. Since the car starts from rest, its initial tangential velocity is zero (v₀ = 0).

Using the equation:

v = v₀ + at

where v is the final tangential velocity, v₀ is the initial tangential velocity, a is the tangential acceleration, and t is the time, we can solve for v:

v = 0 + (0.75 m/s²) * t

v = 0.75t m/s

The tangential velocity is related to the angular velocity (ω) and the radius (r) of the circular track:

v = ωr

Substituting the values:

0.75t = ω * 300

Since the car starts from rest, the initial angular velocity (ω₀) is zero. So, we have:

ω = ω₀ + αt

ω = 0 + (0.75 m/s²) * t

ω = 0.75t rad/s

We can now substitute the value of ω into the equation:

0.75t = (0.75t) * 300

Simplifying the equation gives:

0.75t = 225t

t = 0.75 seconds

The time elapsed is 0.75 seconds.

To calculate the distance traveled (s), we can use the equation:

s = v₀t + (1/2)at²

Since the initial velocity (v₀) is zero, the equation becomes:

s = (1/2)at²

s = (1/2)(0.75 m/s²)(0.75 s)²

s = (1/2)(0.75 m/s²)(0.5625 s²)

s = 0.2119 meters or approximately 21.19 centimeters

Therefore, the car travels a distance of approximately 0.2119 meters or 21.19 centimeters.

Let the angle of inclination be θ,

as shown in figure the forces equation on the block are as follows

Fsinθ = ma , where F=mg

mgsinθ = ma

sinθ = \(\frac{a}{g}\)....................eq1

A type of identity that is almost impossible to achieve during adolescence is vocational identity.

This is because adolescents are still exploring their interests and abilities, and they may not have had enough exposure to different career options to make a confident decision about their future.

In addition, adolescents are often going through a lot of changes, both physically and emotionally. This can make it difficult to focus on the future and to make long-term plans. As a result, many adolescents end up changing their minds about their career goals several times before they finally settle on something.

Answer:

Explanation:

We have to use the equation p = I^2 x R. But we do not have the current.

To work out the current, we look at what we have. We have the voltage and power, therefore we will use the equation P = IV and rearrange to find the current.

I = P/V

I = 60/220

I = 0.2727272727 or round it to 2 dp to get = 0.27

we now have to rearrange the first equation to find the resistance.

R = P/I^2

R = 60/0.2727272727^2

R = 806.6666665501

R = 807 ohms (3sig)

The resistance of the filament is 806.67 ohms.

Electrical power is defined as the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is Watt, 1 joule per second ( 1J/S).

The formula of electrical power is

    P = V^2/R

where,

P = power

V = volts

R = resistance

from the above formula

60 = 220x220/R

R = 220x220/60

The intensity of the light beam is 1.68 x 10⁻⁴ W/m².

The intensity of a light beam is defined as the power per unit area. In this case, we are given the concentration of photons in the beam, which represents the number of photons per unit volume.

To find the intensity, we need to relate the concentration of photons to the power per unit area. The energy of each photon can be calculated using the equation E = hf, where E is the energy, h is Planck's constant (approximately 6.626 x 10⁻³⁴ J·s), and f is the frequency of the light.

Since we know the wavelength of the light (800 nm), we can calculate the frequency using the equation f = c/λ, where c is the speed of light (approximately 3 x 10⁸ m/s).

Once we have the energy of each photon, we can calculate the power per unit volume by multiplying the concentration of photons by the energy of each photon.

Finally, we divide the power per unit volume by the area of the beam to obtain the intensity.

Using these calculations, the intensity of the beam is found to be 1.68 x 10⁻⁴ W/m².

Since N/m is the unit of spring constant N/nm would be the possible unit for a spring constant.

A. N/nm is the possible unit for a spring constant.

The units at the spring regular are Newton/meter (N/m). The poor signal within the above equation is an indication that the direction that the spring stretches is opposite the path of the pressure that the spring exerts.

Because the force is measured in Newtons and the spring consistent is multiplied with the aid of the gap in meters, the spring constant need to have devices that get rid of meters, ensuing most effective force.

According to the given statement , the work done to stretch the spring by 0.04 m is 16 joules (J).

To calculate the work done in stretching a spring, you can use the formula:

Work = (1/2) * k * (x²)

where:
- Work is the amount of work done in stretching the spring (in joules)
- k is the force constant of the spring (in newtons per meter, N/m)
- x is the displacement or stretch of the spring from its equilibrium position (in meters)

In this case, the force constant (k) is given as 2.0 × 10⁴ N/m and the displacement (x) is given as 0.04 m.

To find the work done, substitute these values into the formula:

Work = (1/2) * (2.0 × 10⁴ N/m) * (0.04 m)²

First, calculate (0.04 m)² = 0.0016 m²

Work = (1/2) * (2.0 × 10⁴ N/m) * 0.0016 m²

Next, multiply (2.0 × 10⁴ N/m) by 0.0016 m²:

Work = (1/2) * 32 N * m

Finally, calculate (1/2) * 32 N * m:

Work = 16 N * m

Therefore, the work done to stretch the spring by 0.04 m is 16 joules (J).

velocity changes as follows .

velocity = \(\sqrt{\frac{T}{\frac{m}{4} } }\)

= \(\sqrt{\frac{4T}{m} }\)
