The speed is 0.956 m / s.
<u>Explanation</u>:
The kinetic energy is equal to the product of half of an object's mass, and the square of the velocity.
K.E = 1/2 m
where K.E represents the kinetic energy,
m represents the mass,
v represents the velocity.
K.E = 1/2 m
1.10 10^42 = 1/2 3.26 10^31
= (1.10 10^42 2) / (3.26 10^31)
v = 0.956 m / s.
The answer is option C .Because as the direction of the boy changes ;velocity changes .
Answer:410 Hz
Explanation:
It is given that frequency of tuning fork is 415 Hz and hears a beat of 5 beat per second
so untuned frequency must be either 410 Hz or 420 Hz because beat frequency is the difference in frequency of two notes.
When she tightens the string the beat frequency decrease
and velocity
where
where T=tension
it T increase v also increases and from 1 st equation frequency is also increasing therefore untuned frequency must be 410 Hz because beat frequency is decreasing.
Answer:
<h3>
The magnitude of average induced emf = 0.229 mV </h3>
Explanation:
Given :
Radius of circular loop m
Initial magnetic field T
Final magnetic field T
Difference of magnetic field
Time interval sec.
According to the theory of electromagnetic induction,
Average emf =
Where magnetic flux =
Where area of loop =
Average emf =
Magnitude of average emf = mV
Thus, the magnitude of average induced emf = 0.229 mV
