Force = (mass) x (acceleration)
Mass = (force) / (acceleration)
There was 150N of force in one direction and 100N of 'force' in
the other direction. The net force on the object was (150 - 100) = 50N .
Acceleration = (change in speed) / (time for the change)
= (10 m/s) / (5s) = 2 m/s²
Mass = (net force) / (acceleration) = (50 N) / (2 m/s²) = 25 kilograms
Answer:
Explanation:
B at point 7.0 cm radially outward is to find out?
Now for field strength in case of parallel plates in given as
For the second part as Capacitor is fully charged no more flow of current could take place hence
I= Current =o
so B = 0
There are three factors:
The charge of the two objects. The electric force is proporcional to the product of the charges of both objects.
The distance that separetes them. The electric force is proportional to the inverse of the squared distance that separates the objects.
The media. The electric force constant of proportionality depends on the media: air, water, oil, glass.
Answer:
W = 53.6648 J
Explanation:
W = ∫ F * dr
F = < 4*x i , 3*y j > Newtons
dr = < dx, 0 >
Take the dot product:
F * dr = 4* x * dx
Now replacing numeric
W = ∫ 4 * x * dx , ║ x = ( 0 m ⇒ 5.18 m )
W = ¹ / ₂ * (4 N/m) * x ²
W = (2 N/m) * (5.18 m)²
W = 53.6648 J
Answer:
Explanation:
To answer the question, we just need to consider the motion along the horizontal direction.
The component of the initial velocity of the ice skater along the x-direction is:
where u = 2.25 m/s is the initial velocity and 
is the angle.
The component of the final velocity of the ice skater along the x-direction is
where u = 4.65 m/s is the final velocity and 
is the angle.
The acceleration along the x-direction is given by
where
t = 120 s is the time
Substituting,
