Answer:
106.03 meters
Explanation:
The height is given by the formula for motion under the influence of gravity.
h = -4.9t^2 +162.7
Height is 0 when ...
0 = -4.9t^2 +162.7
4.9t^2 = 162.7
t^2 = 162.7/4.9
t = √(162.7/4.9)
The horizontal distance traveled in that time is ...
(18.4 m/s)√(162.7/4.9) s ≈ 106.03 m
The object will strike the ground about 106.03 meters from the base of the cliff.
They are poor conductors because they keep the heat trapped in one spot, while other materials like metal let the heat go through itself.
Answer:
Work done to lift the box is 515.03 J
Explanation:
By work energy theorem we know that work done by all forces is equal to change in kinetic energy
So we have
so we have
so we have
Answer:
787.5 V/m
Explanation:
the formula to find the electric field in the region between the plates is
E = V/d
where
V=the voltage supplied by the battery (potential)
d=distance between the plates.
E=electric field
Given:
V= 6.3 V
d= 1.6cm/2=> 0.016m/2
E= V/d=> 6.3/(0.016/2)
E= 787.5 V/m
Therefore, the electric field in the region between the plates is 787.5 V/m
