Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Below is the solution:
W done by Normal = 0. (make the incline flat, Normal force goes directly up: no work done)
<span>W done by gravity = w*displacement = (11kg*9.8) * 7.5sin(35) = -463J </span>
<span>W done by friction is the opposite of the work done by weight because the object is not moving. Therefore W done by friction = 463J</span>
Answer:
Explanation:
Given that:
thickness of the metal strip, 
width of the metal strip, 
magnitude of the perpendicular magnetic field, 
current through the strip, 
charge density, 
Hall voltage is a transverse voltage given by:
putting the respective values
Note:
V = E d is used when a charge is moved in a uniform electric field between the two oppositely charged plates, it can't be used here because it is the case of Hall effect where the small voltage develops transverse to the direction of current flow.
Image #3 good luck!!!!!!!!!!!
Mass is the amount of particles present and weight is the amount of gravitational force experienced by a body. Since gravity changes from one celestial object to another, weight of a body changes accordingly. But it's mass remains constant since the amount of particles present in that object doesn't change anywhere
