Answer:
625 N
Explanation:
The impulse given to the nail is equal to the change in momentum of the hammer:
where
F is the force exerted by the hammer
is the time of contact
is the mass
is the change in velocity of the hammer
Substituting the data and re-arranging the equation, we can find the force:
The speed of the proton is
Data;
- potential difference (A) = 3500V
- potential difference (B) = -1500V
<h3>Velocity of The Proton</h3>
The work done to move through a potential velocity 'v' is q
The potential difference 'v' is the difference between A and B
But the work is converted into kinetic energy of proton.
Let's substitute the values and solve for the velocity
The speed of the proton is

False.
The statement that Current ethical standards for psychology experiments were established by Freud in the 1920s is false. The current ethical experiments for psychology experiments were established by psychologists like Watson and Raynor (research on Little Albert -1920), Milgram’s interest in obedience (1963-1964), Humphrey’s naturalistic observations of tea rooms etc.
Answer:
118.166 volt
Explanation:
We have given number of turns N =345
Sides of the rectangular coils is 12 cm =0.12 m
So area A =0.12×0.12=0.0144
Magnetic field B =0.45 T
Angular speed =505 rpm
Speed in rad/sec
The emf is given by
For maximum emf sinwt =1
So
First off, you can cross out alternating current because a 9V battery doesn't give out AC, it gives out solely DC. If the battery is connected to each battery individually, then they are in parallel. So, according to Kirchhoff's Voltage Law, in parallel, V total = V1 = V2= V3..
So I'd say B) !
