there will no resultant force
Explanation:
this is because if the forces are balanced on opposite direction. then they cancel each other out
5 newton's ---------> <--------- 5 newton's
then both forces will cancel each other out as a result there is no resultant force and the newton's laws states that if there is no resultant the object will continue in its state of rest (remains there) or it will in continue in its uniform motion in a straight line.
I hope you understand,
M=3kg
p=33kg.m/s
p=m*v
v=p/m
=33/3
=11m/s
thus option (c)
potential energy = mass × gravity × height
so, change in potential energy = mass × gravity × change in height
2 = 50 × 10 × Δh
2 ÷ 500 = Δh
Δh = 0.004 m
This distance does depend on the initial velocity of the ball.
Answer:
a positive test charge will move in the field
Explanation:
The direction of an electric field corresponds to the direction of motion of a positive test charge in the electric field. In fact:
- the electric field produced by a positive charge points outwards the charge --> this is because when a positive test charge is placed in this field, it will feel a repulsive force (because two positive charges repel each other), so it will move away from the positive charge that produces the field
- the electric field produced by a negative charge points towards the charge itself--> this is because when a positive test charge is placed in this field, it will feel an attractive force (because a positive and a negative charge attract each other), so it will move toward the negative charge that produces the field.
Answer:
The field losses a total of 55.814 litres of water in an hour.
Explanation:
As the complete question is not given here, the average rate of water loss is not given here which is found in normal conditions as 1.67 mL/m2.
Now the average rate of water loss per minute is 1.67 mL/m2
So the average rate of water loss per minute for 557 m2 is 1.67*557=930.19 mL
So 930.19 mL of water is lost from the field in 1 minute, for the calculation of water lost in an hour, the value is given as 60*930.19 =55811.4 mL or 55.814 litres.
