Answer:
t = 4 seconds
Explanation:
The question is "The intensity of current flowing through a conductor is 2μA. How long will it take 5x1013 electrons to cross a certain cross section of the conductor?
"
Current, 
No of electrons, 
We need to find how long will it take to given no of electrons to cross a certain cross section of the conductor.
Electric current,
t is time
Also, q = ne
So, it will take 4 seconds.
The displacement would be the final position (37) minus the initial position (50) if using the displacement formula.
Answer:
Mechanical advantage = 15
Explanation:
Given the following data;
Output force = 3000N
Input force = 200N
To find the mechanical advantage;
Mechanical advantage = output force/input force
Substituting into the equation, we have
Mechanical advantage = 3000/200
Mechanical advantage = 15
Answer:
4. Parabola
Explanation:
The motion of the flight of the grenade is a projectile motion, it's shape is best illustrated using a parabolic diagram.
It's not a circle as the path is not totally round.
It's not an ellipse as the path of motion is not a a completely bounded shape.
Its not a hyperbola as a hyperbola is an open curve with two branches.
Its a parabolic shape because a parabola has just one branch
The angle of reflection is the angle that the reflected ray makes with a line drawn perpendicular to the reflecting surface.
