Acceleration  =  (change in speed)  /  (time for the change)

                       =      (49 m/s)   /   (5 seconds)

                       =       (49 / 5)  m/s  /  s

                       =            9.8 m/s²

A generator has a 100-turn coil that rotates in a 0.30-T magnitude B-field at a frequency of 80 Hz. The area of each loop is 0.0
loris [4]

Answer:

Explanation:

Flux Φ = nBA sinωt

t = 0 , flux = 0

dΦ / dt = nωBA Cosωt

e = nωBA Cosωt

= 100 x 2πx80 x.3 x .003 cos 2πx80 x .014

= 45.21 cos 7.0336

= 33.0668 v

= 33.1 V

Somebody help!?
nevsk [136]

Answer:

acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.

Explanation:

Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the meter per second squared .

Is molded bread a physical or chemical change?
V125BC [204]
<span>A molded bread is a good example of a chemical change. A chemical change is a kind of change in which a new substance is formed. In a chemical change, the original substance which started the reaction can not be recovered.The molded bread formed in this given instance is a new substance which is different from the original bread, so also, the original bread can no longer be retrieved from the molded bread.</span>
