Answer:
The average induced emf in the loop is 0.20 V
Explanation:
Given:
Radius of loop 
m
Magnetic field 
T
Change in time 
sec
According to the faraday's law,
Induced emf is given by
Where 
magnetic flux
( here 
)
Where 
We neglect minus sign because it's shows lenz law
V
Therefore, the average induced emf in the loop is 0.20 V
Answer:
you counteract the Chromozones with the numerzones which contacts the specimen in the brain cells which then has voltage in the hand that connects with the wire then wallah
Explanation:
We Know,
K.E. = 1/2 mv²
480 = 1/2 (m)(8)²
m = 960/64
m = 15 Kg
So, the mass of the object is 15 Kg
The wavelength of the note is
. Since the speed of the wave is the speed of sound,
, the frequency of the note is
Then, we know that the frequency of a vibrating string is related to the tension T of the string and its length L by
where
is the linear mass density of our string.
Using the value of the tension, T=160 N, and the frequency we just found, we can calculate the length of the string, L:
Answer:
a = -4/5 m/s^2
Explanation:
Acceleration = change in velocity / time
change in velocity = final velocity - initial velocity
a = (20 m/s - 60 m/s) / 50 s
a = -40 m/s / 50 s
a = -4/5 m/s^2
hope this helps! <3
