A Ferris wheel has a radius of 25 feet. The wheel is rotating at two revolutions per minute. Find the linear speed, in feet per

svet-max [94.6K]

Linear velocity and angular velocity are related by the formula:
v = ωr

ω = n2πr/t, where n is the number of rotations, t is the time taken, r is the radius.
ω = 2 x 2π x 25/1
ω = 100π

v = 100π x 25
= 2500π feet per minute

A circular conducting loop of radius 23.0 cm is located in a region of homogeneous magnetic field of magnitude 0.500 T pointing

Alchen [17]

Answer:

The magnitude of the induced emf is

Ф = 5.419 x 10⁻³ V

Explanation:

Given:

r = 23.0 cm = 0.23 m

β₁ = 0.50 T

β₂ = 2.50 * 0.50 T = 1.25 T

Calculate the magnitude of the induced emf the magnetic field is increasing

Ф = A * Δβ / Δt

A = π * r² = π * 0.23² m = 0.166 m²

Ф = 0.166m² * (1.25 - 0.5) T / 23 s

Ф = 5.419 x 10⁻³ V

You drive a car 1500 ft to the east, then 2500 ft to the north. if the trip took 3.0 minutes, what were the direction and magnit

Lelu [443]

The velocity of the car was 4.93m/s and the direction was northeast.

<h3>Calculation</h3>

It is given,

time of the trip = t = 3 minutes = 180 seconds

1st distance A = 1500ft = 457.2m east

2nd distance B = 2500ft = 762m north

We are asked to find the average velocity.

First, we get the resultant distance magnitude by applying Pythagoras theorem to find the hypotenuse.

$A^{2} + B^{2} =C^{2} \\C=\sqrt[]{A^{2} +B^{2} } \\C=\sqrt{457.2^{2} +762^{2} } \\C= 888.63m$

Then we have

Velocity = Distance/time

Velocity = 888.63/180

Velocity = 4.93 m/s

Then the direction is northeast.
