A closed loop conductor with radius 2.0 m is located in a changing magnetic field. If the maximum emf induced in the loop is 2.0

V, what is the maximum rate at which the magnetic field strength is changing if the magnetic field is oriented perpendicular to the plane in which the loop lies?

Answer:

0.159 Tesla per second

Explanation:

r = 2 m, e = 2 V,

Let the rate of magnetic field changing is dB / dt.

By use of Farady's law of electromagnetic induction

e = rate of change of magnetic flux

e = dФ /dt

e = A x dB / dt

2 = 3.14 x 2 x 2 x dB / dt

dB / dt = 0.159 Tesla per second

The air movements toward the equator are called trade winds, which are warm, steady breezes that blowalmost continuously. The Coriolis Effect makes the trade winds appear to be curving to the west, whether they are traveling to the equator from the south or north. Answer trade wind

As there is no postive or negative assigned so
Initial velocity= -2.8759
Displacement= 0.5at^2+ut
= 0.5(-1.77)(3.33)^2+(-2.8759)(3.33)=-19.4m

A car, initially traveling at 81.8 mi/h, slows to rest in 7.1 s. What is the car's acceleration?
maksim [4K]

Answer:

a = -16.9 ft/s²

Explanation:

81.8 mi/hr(5280 ft/mi / 3600s/hr) = 120 ft/s

a = Δv/t = (0 - 120) / 7.1 = -16.9 ft/s²

if the initial direction is taken as the positive direction.

archer shoots his arrow towards a target at a distance of 90 m, and hits ‘bullseye’ . Calculate the acceleration and time taken
mario62 [17]

Answer:

a =45 m/s2

t = 2 seconds

Explanation:

Hi, to answer this question we have to apply the next formula:

v^2 = u^2 +2 a d

Where:

v = final velocity = 90 m/s

u = initial velocity = 0 m/s (shots from rest)

a = acceleration (m/s2)

d = distance = 90m

90^2 = 0^2 + 2a(90)

Solving for a:

8,100= 180 a

8,100/180 = a

a = 45 m/s^2

For time:

v = u + at

90 = 0 + 45t

90/45=t

t =2 seconds
