The bike and rider must halt at a breaking distance of 5.17 meters.

d=2.2v+fracv220 gives the braking distance, in feet, of a car moving at v miles per hour. Most motorcycle riders have a maximum braking force (what an experienced rider can do) of about 1 G, which, at 45 mph, results in a complete stop of the motorcycle in 67 feet (20 meters).

To resolve this issue, we can apply the equation of motion for uniformly accelerated motion:

v² = u² + 2as

To solve for s, we can rewrite the equation as follows:

s = (v² - u²) / (2a)

We are aware that the acceleration is determined by dividing the net force by the mass:

a = F_net / m

where m is the mass and F net is the net force.

a = F_net / m = -140 N / 82.0 kg

= -1.71 m/s²

We may now change the values for s in the equation:

s = (0² - 4.2²) / (2*(-1.71))

= 5.17 m

The angular velocity assuming a constant speed for a track-star who runs 400 m circular track in 45 s is 0.139 radians/s.

To calculate the angular velocity first the circumference of the track is 400 meters.

This means that the angular displacement of the track star during the race is:

θ = s / r

where θ is the angular displacement,

s is the distance traveled by the track star (which is equal to the circumference of the track), and

r is the radius of the circular track.

2.) Since the radius of the circular track is half of its diameter, we have:

r = 400 m / 2 = 200 m

Plugging this into the equation for angular displacement, we get:

θ = 400 m / 200 m = 2π radians

3.) Next, we can use the formula for angular velocity:

ω = θ / t

where ω is the angular velocity and

t is the time it takes for the track star to complete the race.

4.)Plugging in the values we have:

ω = θ / t

ω = 2π radians / 45 s

Therefore, the angular velocity of the track star is:

ω = 0.139 radians/s (rounded to three significant figures)

Therefore, the track star's angular velocity assuming a constant speed is approximately 0.139 radians/s

The angular displacement of the track star is equal to one complete revolution around the circular track, which is equal to 2π radians.

The primary mirror of an astronomical telescope is often shaped and polished to a parabolic shape because a parabolic shape allows for the mirror to collect the most amount of light and focus the parallel rays of light to a single point for better image clarity.

The reason that the primary mirror of an astronomical telescope is often shaped and polished to a parabolic shape is to reduce spherical aberration.

What is an astronomical telescope?An astronomical telescope is an optical instrument that aids in the observation of remote objects by collecting electromagnetic radiation such as visible light. It consists of two primary components: a primary mirror or lens that gathers and focuses light, and an eyepiece or camera that magnifies and projects the image formed by the primary.

A parabolic shape is a mirror or lens that has a curve that is more curved in the center than at the edges, and it is often used in astronomical telescopes to reduce spherical aberration. Spherical aberration is an optical defect that causes the image of a point source to become fuzzy and blurred. It occurs when the rays passing through the edges of a spherical lens or mirror become focused at a different distance than those passing through the center. This causes the image to be blurred around the edges, which makes it difficult to view small or distant objects. Parabolic mirrors are used to correct this problem because they are designed to focus all incoming light to a single point, resulting in a sharper and clearer image.

Blood flows with a speed of 30 cm/s along a horizontal tube with a cross-section diameter of 1.6 cm.The speed of blood flow in the part of the same tube that has a diameter of 0.8 cm is 15 cm/s.

To arrive at this answer, we can use the formula for the flow rate of a fluid in a pipe:
Q = A × V
where Q is the flow rate, A is the cross-sectional area of the pipe, and V is the velocity of the fluid.
Therefore, if we substitute the values for A and V of the first section, we can calculate the flow rate for that section:
Q1 = A1 × V1
Q1 = π ×(1.6 cm/2)² × 30 cm/s
Q1 = 24.72 cm³/s
Now we can use the flow rate and the cross-sectional area of the second section to calculate the velocity of the fluid:
Q1 = A2 × V2
V2 = Q1 / A2
V2 = 24.72 cm³/s / (π × (0.8 cm/2)²)

When an object is placed in water, it sinks until the weight of the water displaced by the object equals the weight of the object.

If an object has the same density as water, it displaces an equal amount of water to its own weight. When it displaces the same amount of water that has an equivalent mass to the object, it will float partially submerged. If the object's density is greater than water, it will sink. If the object's density is less than that of water, it will float entirely above the water's surface.

Density is defined as the mass of an object per unit volume. The formula for density is mass/volume. Density is a crucial physical property that is used to define and classify materials. The density of an object is determined by its mass and volume. The unit of measurement for density is kg/m3 or g/cm3.

If a star is 11 pc away from us, its apparent visual magnitude will be lower than its absolute visual magnitude. The star's apparent magnitude would be only 0.38 magnitudes lower than its absolute magnitude.

This is because the apparent magnitude of a star is affected by its distance from us. As the distance increases, the star appears dimmer, and its apparent magnitude decreases.

The distance modulus formula gives us a way to calculate the difference between the apparent and absolute magnitudes of a star:

Distance modulus = 5 * log(distance in parsecs) - 5

For a star that is 11 pc away, the distance modulus is,

Distance modulus = 5 * log(11) - 5 = 1.38

This means that the star's apparent magnitude will be 1.38 magnitudes lower than its absolute magnitude.

If the same star were only 5 pc away from us, the distance modulus would be,

Distance modulus = 5 * log(5) - 5 = 0.38

The length of the string is 0.48 m.

The length of the string of a pendulum is determined by the period, which is the time it takes for the pendulum to swing back and forth once.

String length = (Gravitational acceleration x (Period)2) / (4π2)

Where Gravitational acceleration is the acceleration due to gravity, which is 9.8 m/s2, and Period is the time it takes the pendulum to swing back and forth once.

The period is 10 seconds divided by 15 swings, or 0.67 seconds.

String length = (9.8 m/s2 x (0.67 s)2) / (4π2) = 0.48 m.

Therefore, the length of the string is 0.48 m.

The kinetic energy of the ball when hits the ground is 88.2 J

The formula for calculating kinetic energy is

KE = 1/2mv²

Where KE is kinetic energy, m is mass, and v is velocity.

We have, the mass of the bowling ball is 6 kg, and it is dropped from a height of 1.5 m, we can calculate its velocity just before it hits the ground as follows:

Potential energy = mgh

Where m = mass of the object = 6 kg

g = acceleration due to gravity (9.8 m/s²), and

h = height from which the object is dropped = 1.5 m

PE = mgh

= (6 kg)(9.8 m/s²)(1.5 m)

= 88.2 J

The potential energy of the bowling ball is 88.2 J.

This is equal to its kinetic energy just before it hits the ground.

Therefore, the kinetic energy of the ball is 88.2 J.

The electric field stored between two square plates of 9.3 cm on a side and separated by a 2.5 mm air gap is 1110 N/C. This can be calculated using Coulomb's law and the given information.

Coulomb's law states that the electric field is equal to the charge (Q) divided by the permittivity of free space (ε₀) multiplied by the distance (d) squared:

E=Q/(ε₀*d²).
Plugging in the given information,

E=(13 nC)/(8.85 x 10⁻¹² * 0.0025²) = 1110 N/C.
This answer uses Coulomb's law to calculate the electric field stored between two square plates, given the plates' side lengths, air gap width, and charge magnitude.
