Answer:
The answer is Producer. Hope this helps!
Answer:
it's answer is 5 seconds,
Explanation:
Given
Power (p) = 400 watt
work (w) = 2000 J
time taken (t) = ?
we know that,
p = w/t
400 = 2000 / t
t = 2000/400
Therefore t = 5 sec
The correct answer is A, electrons enter orbitals of lowest energy first. The Aufbau principle states that electrons orbiting atoms fill the lowest energy levels available before filling higher levels. Following this, molecules can go into the most stable electron configuration.
Answer:
if Y is the position and X the time: in the first one you will see a crescent function that starts sharp and starts to curve down as the time pases. as the cart is slowing down, you will need more time to move the same as before.

in the second case the cart starts close to the sensor and starts getting sharper and sharper as the time pases. This is because the velocity is increasing, so for each second that pases, you will travel more distance that the second before it.

i hope you can understand it, kinda hard to do graphs here.
Answer:
The force on the proton will be twice in comparison with the force experienced by the electron.
Explanation:
The magnetic force acting on the moving charge particle is perpendicular to the velocity as well as the magnetic field. The factors upon which the magnitude of the force is depending and proportional are as follows:
1 Magnitude of the charge particle.
2 Magnitude of the velocity of moving charge.
3 Magnitude of magnetic field.
4 Sine of angle between the velocity and magnetic field.
As far as direction is concerned, it can be find out by right hand rule.
Lets consider,
Speed of electron = Ve
Speed of proton vp= 2ve
Magnitude of the force F = qvBsin∅
Force acting on electron Fe = qe.ve.Bsin∅
Force acting on proton Fp = qp.vp.Bsin∅
Fp = -2 qe.ve.Bsin∅
Fp = -2Fe
Negative sign shows the direction of Force on proton is opposite to the direction of force on electron.
