Answer:
Time taken by the arrow to travel along to hit the ground is 0.55 seconds.
Explanation:
The only "force" acting on the "crossbow" to cause it to "hit" the ground is "gravity". There is no initial velocity downward when it shoot.

d = the displacement of the object
t = the time for which the object moved
a = acceleration of the object
= the initial velocity of the object
Given values
d = 1.5 m
t = unknown






Square root both sides

t = 0.55 s
Answer: Kinetic energy increases and potential energy decreases when the velocity of an object increases
Explanation: probably that one
Answer:
0.107 m
Explanation:
The magnetic field at the center of a current-carrying loop is given by

where
is the vacuum permeability
I is the current
r is the radius of the loop
In this problem we have
I = 3.40 A is the current in the loop
is the magnetic field at the centre of the loop
So, solving the formula for r we find
