Answer:
sum of the two forces as both point to the right is a force that points to the right,
Explanation:
The force on the cast load at point Y is given by
F = q_y E
force is a vector magnitude so its result is
∑ F = Fₐ + F_b
indicate that the charge at y is negative, we analyze the direction of the force created by each charge
Charge A
as the electric field is incoming the charge is negative and as the test charge is negative both repel each other, consequently the force points to the right
Charge B
in this case the electric field lines are salient, therefore the charge is positive, consequently the force on the charge at y is attractive and points to the right
the sum of the two forces as both point to the right is a force that points to the right, that is, in the direction of the charge located at B
The moon lacks an atmosphere compared to the Earth. Hope this helps!
Answer:
A
Explanation:
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. ... This means that some individuals would survive and be able to reproduce and generate more offspring.
In collision type of problems since momentum is always conserved
we can say
So here along with this equation we also required one more equation for the restitution coefficient
so above two equations are required to find the velocity after collision
here the change in velocity occurs due to the contact force while they contact in each other
so this is the impulse of collision while they are in contact with each other while in collision which changes the velocity of two colliding objects
