Answer:
No
Explanation:
A goal can be scored directly from a goal kick against the opposing team. An own goal cannot be scored from a goal kick; in the highly unlikely circumstance that the ball enters the kicker's own goal before being touched by another player, a corner kick is awarded.
Answer:
The correct option is D
Explanation:
From the question we are told that
The speed of the first charge is 
This is because it is at rest
The speed of the second charge is 
Generally the force exerted by a magnetic field on a charge is mathematically represented as
Now looking at this above equation we can see that 
can only be maximum at 
and this only obtained when the direction of the charge (i.e its velocity ) is perpendicular to the direction of the magnetic field
so the correct option for this question is D
Answer:
I think the answer the this question that you asked is pulse?
Answer:
Part A W= 2772J
Part B = -2.772J
Explanation:
Work = force × distance
Part A when you move from lower to upper level
= mgh
= 63× 4.4×10
=2772J
=2.772KJ
Part B
When you move from upper to lower
The acceleration due to gravity becomes negative -10m/s^2
Therefore Work =-2772KJ
Work = -2.772KJ
