how to find velocity with constant acceleration

The factor that has the greatest effect on the strength of an electromagnet is the magnitude of the electric current flowing through the electromagnet's coil.

Number of Turns in the Coil: increasing the number of turns in the coil of the electromagnet enhances its magnetic field strength. Each turn contributes to the overall magnetic field, so more turns mean a stronger magnetic field.

Core Material: the type of material used as the core within the electromagnet can impact its strength. Certain materials, such as iron or steel, can enhance the magnetic properties of the electromagnet by providing a more conducive path for magnetic flux.

Coil Size: the size of the coil can influence the strength of the electromagnet. A larger coil typically results in a stronger magnetic field due to the increased number of wire turns and the greater area covered by the coil.

The average power output is 7.72 kW

When referring to energy delivery, the term "power output" is used. When used in reference to the automotive sector, it refers to the quantity of mechanical energy output produced by the motor, once again within a predetermined interval.

As a 550 kg dragster accelerates from rest to a final speed of 120 m/s in 450 m, facing an average frictional force of 1200 N, and doing so in 7.30 seconds, its average power output is 7.72 kW..

This can be calculated using the equation Power = (Force x Distance) / Time. In this case, the Force is 1200 N, the Distance is 450 m, and the Time is 7.30 seconds. Plugging these values into the equation, we get:

Power = (1200 N x 450 m) / 7.30 s
Power = 7,720 / 7.30 s

Answer:

a. 26.7 cm. b. 11.4 cm.

Explanation:

a. We know h'/h = d'/d where h' = image height = + 2 cm (since it is a real image), h = object height = + 1.5 cm, d' = image distance from mirror and d = object distance from mirror = 20 cm

So, from h'/h = d'/d

d = h'd/h

= 2 cm × 20 cm/1.5 cm

= 40/1.5 cm

=  26.67 cm

≅ 26.7 cm

The position of the image is 26.7 cm from the mirror

b. Using the mirror formula

1/d + 1/d' = 1/f where d = object distance from mirror = + 20 cm, d' = image distance from mirror = + 26.7 cm (its positive since its a real image) and f = focal length of mirror.

So, 1/d + 1/d' = 1/f

⇒ f = dd'/(d + d')

= 20 cm × 26.7 cm/(20 cm + 26.7 cm)

= 534/46.7

= 11.43 cm

≅ 11.4 cm

The focal length of the mirror is 11.4 cm

The speed of the bat emitting sound at a frequency of 30.0 kHz is closest to 10.0 m/s.

Based on the given information, we can find the speed of the bat using the formula:

Speed of sound = Frequency x Wavelength

Since the frequency of the sound emitted by the bat is 30.0 kHz (30,000 Hz) and the frequency of the echo is 900 Hz higher, the frequency of the echo is 30,000 Hz + 900 Hz = 30,900 Hz.

We can calculate the wavelength of the emitted sound using the formula:

Wavelength = Speed of sound / Frequency

Using the given speed of sound in air, which is 340 m/s, and the frequency of the emitted sound, we get:

Wavelength = 340 m/s / 30,000 Hz = 0.0113 meters

Since the frequency of the echo is higher, it means that the bat is moving towards the wall. In this case, the Doppler effect causes the frequency to increase.

The Doppler effect formula is:

Change in frequency / Frequency = Speed of observer / Speed of sound

We know the change in frequency is 900 Hz, the frequency is 30,000 Hz, and the speed of sound is 340 m/s.

900 Hz / 30,000 Hz = Speed of observer / 340 m/s

Speed of observer = (900 Hz / 30,000 Hz) x 340 m/s = 10.2 m/s

Therefore, the speed of the bat is closest to 10.0 m/s.

The question should be:

The bat emits sound at a frequency of 30.0 kHz as it moves closer to a wall. The bat detects beats where the frequency of the echo is 900 Hz greater than the emitted frequency. The speed of sound in air is 340 meters per second.The speed of the bat is closest to Group of answer choices 10.0 m/s 30.0 m/s 0 20.0 m/s 530 m/s. 5.02 m/s

The direction of the force from wire 1 on wire 2 is attractive, as the two currents are in the same direction.

If two currents are flowing in the same direction and the forces between the wires are attractive, then the direction of the force on wire 2 due to wire 1 will be towards wire 1. This is because the magnetic field created by the current in wire 1 will induce a magnetic field in wire 2, and the interaction between these two magnetic fields will result in an attractive force between the wires.

In summary, if two currents are flowing in the same direction and the forces are attractive, the direction of the force on wire 2 due to wire 1 will be towards wire 1.

Explanation:

Autosomes are homologous chromosomes i.e. chromosomes which contain the same genes (regions of DNA) in the same order along their chromosomal arms. The chromosomes of the 23rd pair are called allosomes consisting of two X chromosomes in most females, and an X chromosome and a Y chromosome in most males.

The wave speed when the suspended mass is m = 2.00 kg is  31.7 m/s. To solve this problem, we'll use the wave equation:

v = √(T/μ)

where:

v is the wave speed,

T is the tension in the string, and

μ is the mass per unit length of the string.

(a) To find the mass per unit length of the string, we'll rearrange the equation:

μ = T / \(v^2\)

Given:

v = 24.0 m/s

m = 3.00 kg

We need to find the tension T. The tension in the string is equal to the weight of the suspended mass, which is given by:

T = m * g

where g is the acceleration due to gravity (approximately 9.8\(m/s^2\)).

Substituting the values, we have:

T = (3.00 kg) * (9.8\(m/s^2\))

T ≈ 29.4 N

Now, we can calculate the mass per unit length:

μ = (29.4 N) / (24.0\(m/s^2\))

μ ≈ 0.06125 kg/m

Therefore, the mass per unit length of the string is approximately 0.06125 kg/m.

(b) To find the wave speed when the suspended mass is m = 2.00 kg, we can use the same equation:

v = √(T/μ)

We already know the tension T from part (a), which is 29.4 N. We can substitute this value and the new mass into the equation:

m = 2.00 kg

v = √((2.00 kg * 9.8 \(m/s^2\)) / (0.06125 kg/m))

v ≈ 31.7 m/s

Therefore, the wave speed when the suspended mass is m = 2.00 kg is

31.7 m/s.

To determine the diameter of the cylindrical rod that can withstand a load of 650 N, we need to consider the yield strength of the material and the applied load. the diameter of the rod is approximately 11.62 mm.

By using the formula for stress (force divided by area) and rearranging it to solve for the diameter, we can find the required diameter of the rod.

The stress experienced by the rod can be calculated using the formula:

Stress = Force / Area

Given that the yield strength of the steel is 310 MPa, we can set up the equation:

310 MPa = 650 N / (π * (diameter/2)^2)

We can rearrange the equation to solve for the diameter:

diameter = √(650 N / (310 MPa * π)) * 2

Substituting the given values, we find:

diameter ≈ √(650 / (310 * 10^6 * π)) * 2 ≈ 11.62 mm

Therefore, the required diameter of the rod to withstand the load is approximately 11.62 mm.

Answer:

- Decreasing the resistance

- Using a shorter length

- Using a smaller area wire

Explanation:

Formula for conductance in wires is;

G = 1/R

Where;

G is conductance

R is resistance

This means that increasing the resistance leads to a larger denominator and thus a smaller conductance but to decrease the denominator means larger conductance.

Thus, to increase the conductance, we have to decrease the resistance.

Resistance here has a formula of;

R = ρL/A

Where;

ρ is resistivity

L is length of wire

A is area

Thus, to decrease the resistance, we will have to use a shorter length and smaller area of wire.

(1) The time does pilot take the weight to hit the ground = 2.4 s

(2) The pilot travel before land = 400 m

Because fall time is proportional to fall height and acceleration due to gravity (g) is constant,

t₁ = t₂  

s₁ = initial distance

s₂ = final distance

t₁ = initial time

t₂ = final time

Hence, the time does it take the weight to hit the ground = 2.4 s

The initial distance (s₁) = 200 m, and the pilot does a run at the same height but twice the speed.

So, the  pilot travel before land:

s₂ = 2 x s₁
