Explanation:

The linear velocity of one of the teeth at the edge of the 8-inch diameter blade is approximately 107.143 miles per hour.

The circumference of the blade is given by:

Circumference = π x diameter

Circumference = 3.14159 x 8 inches ≈ 25.13274 inches

To convert the linear velocity to miles per hour, we need to convert inches to miles and minutes to hours. There are 63360 inches in a mile and 60 minutes in an hour.

Linear velocity = (Circumference x RPM) x (1 mile/63360 inches) x (60 minutes/1 hour)

Linear velocity = (25.13274 inches x 3650 RPM) x (1 mile/63360 inches) x (60 minutes/1 hour)

Linear velocity ≈ 107.143 miles per hour

Therefore, the linear velocity of one of the teeth at the edge of the 8-inch diameter blade is approximately 107.143 miles per hour.

What is dimensions?

An item, region, or space's dimensions are its size or distance from another point in space. The metric of anything's length, width, and height can be put more simply.

Length and Breadth are  a common way to convey dimensions. 

Main body:

Volume of cylinder, \(v = \pi r^{2}h\)

Surface area = \(2\pi r^{2} + 2\pi rh\)

given surface area = \(1500 cm^{2}\)

\(h=(750/\pi r)-r ---(1)\)

V = \(\pi r^{2}\left \{ {(750/\pi r)-h\)

V = 750-3\(\pi r^{2}\)

put V' = 0

0 = 750-3\(\pi r^{2}\)

r≈ 8.92 cm

By substituting the value of r in eq (1)

a) Mutual inductance, M between coil A and coil B can be given as:

M = k√(L_AL_B) here, k is the coupling coefficient, L_A and L_B are the inductances of the coil A and coil B respectively. Since 54% of flux produced by coil A links coil B,

So, K = 0.54

L_A = N_A Φ/I_AL_A

= 8120 × 0.02/6

= 27.07 mH

L_B = N_B Φ/I_BL_B

= 11842 × 0.078/6

= 154.63 mH

M = k√(LALB) = 0.482 × √(27.07 × 0.15463) = 0.108 H

Answer:

electrons can be removed or added creating ions of the element

Explanation:

As clench force increases, the amplitude of the EMG signal also increases because more motor units are recruited to generate the force required for the contraction.

EMG (Electromyography) is a technique used to measure the electrical activity of muscles. When a muscle contracts, it generates electrical activity that can be detected by placing electrodes on the skin overlying the muscle.

As clench force increases, the amplitude of the EMG signal also increases. This is because more and more motor units are recruited to generate the force required for the contraction. A motor unit consists of a motor neuron and the muscle fibers it innervates. For low-force tasks, only a few motor units are recruited, whereas for high-force tasks, many motor units are recruited.

The recruitment of motor units follows the size principle, which states that smaller motor units are recruited first followed by larger motor units as force increases. As force increases, larger motor units are recruited, resulting in an increase in the amplitude of the EMG signal.

The magnitude and direction of the electric field at a point on the y-axis (y = a) due to charges 2q and -q located at the origin and x = 2a respectively can be determined using the principles of electrostatics.

To find the electric field at a point on the y-axis, we can consider the contributions from both charges. The electric field due to a point charge is given by Coulomb's Law, which states that the magnitude of the electric field (E) is proportional to the magnitude of the charge (q) and inversely proportional to the square of the distance (r) between the charge and the point of interest.

For the charge 2q at the origin, the electric field at a point on the y-axis can be calculated using the formula \(E1 = k(2q)/(r1^2)\), where k is the electrostatic constant and r1 is the distance between the charge 2q and the point on the y-axis.

Similarly, for the charge -q at x = 2a, the electric field at the same point can be calculated using the formula \(E2 = k(-q)/(r2^2)\), where r2 is the distance between the charge -q and the point on the y-axis.

To find the total electric field at the point, we need to consider the vector sum of the electric fields due to each charge. The direction of the electric field at the point on the y-axis will depend on the directions and magnitudes of the individual electric fields.

By calculating the magnitudes and directions of E1 and E2, we can determine the magnitude and direction of the total electric field at the point on the y-axis.

If the majority of the objects observed had a redshift (spectral lines shifted toward the red end of the spectrum), this means these objects are all moving:  away from the milky way. The correct option to this question is A.

Redshift refers to the phenomenon where the spectral lines of an object are shifted towards the red end of the spectrum due to the Doppler effect. This occurs when the object is moving away from the observer, in this case, the Milky Way.

The majority of objects observed with redshift are moving away from the Milky Way, which supports the idea of an expanding universe.

In the context of astronomy and astrophysics, the observation of redshift in the majority of objects indicates that these celestial bodies are moving away from our galaxy, the Milky Way.

This observation provides evidence for the theory of an expanding universe, which is a fundamental concept in our understanding of the cosmos.

Answer:

Acceleration is the rate of change of velocity.

Explanation: For example, acceleration is measured in m/2^2 or meters per second squared. That can also be split up into 2 components. M/s is how speed is measured, and since acceleration is the rate of change of velocity, m/(s*s). You could say that since acceleration is m/s^2, it can also be represented as how much the speed increases over 1 second. if there was an acceleration of 3 m/s^2, the rate of change of speed would be 3m/s every second, meaning that the object would speed up 3m/s every second that passes by.

Answer:  A or D

Explanation:

I need to see the graph

Answer:

the correct answer is D

Explanation:

The radius of the turn can be calculated using the centripetal acceleration formula:a_c = v^2 / rwhere a_c is the centripetal acceleration, v is the velocity of the falcon, and r is the radius of the turn.

We know that the centripetal acceleration of the falcon is 1.5 times the free-fall acceleration, which is approximately 9.8 m/s^2. Therefore, the centripetal acceleration of the falcon is:a_c = 1.5 * 9.8 = 14.7 m/s^2We also know that the velocity of the falcon is 30 m/s. Substituting these values into the centripetal acceleration formula, we get:14.7 = 30^2 / rSolving for r, we get:r = 591.8 meters (approx.)Therefore, the radius of the turn is approximately 591.8 meters.Explanation:When a falcon makes a tight circular turn, it needs to generate a centripetal force to keep it moving in a circular path. The centripetal force is generated by the centripetal acceleration, which is directed towards the center of the circle.The centripetal acceleration depends on the velocity of the falcon and the radius of the turn. The faster the falcon is flying or the tighter the turn, the greater the centripetal acceleration required.In this problem, we are given the velocity of the falcon and the centripetal acceleration it can generate. We can use the centripetal acceleration formula to find the radius of the turn.The radius of the turn tells us how tight the turn is. A smaller radius means a tighter turn, which requires a greater centripetal acceleration. In this case, the falcon is able to generate a centripetal acceleration 1.5 times the free-fall acceleration, which is quite impressive and allows it to make tight turns while hunting its prey.
