Ball X is dropped from a height of 1.25 meters above the ground. At the same time and from exactly the same height, Ball Y is shot out horizontally at an initial velocity of 8.0 m/s. Air resistance is negligible and assume g =-10 m/s?
How far away from Ball X will Ball Y hit the ground?

The distance between Ball X and Ball Y is 4.0 meters

Explanation:

First we have to use the information we have from Ball Y to find time as well as it’s distance.

Ball Y’s Given:

Vx=8.0m/s

ax=0m/s^2

x=?

y=1.25m

ay=-10m/s^2

To find the time, use the equation t=(2y/g)^1/2.

t=(2(1.25)/10)^1/2

t=(2.5/10)^1/2

t=(0.25)^1/2

t=0.5s

Now we have to calculate how far away Ball Y fell from the base of the cliff. To do this use the equation x=(Vx)(t) and plug in the values.

x=(8.0m/s)(0.5s)

x=4.0m

Because Ball X is dropped from the cliff, we can conclude that the ball is 0meters away from the cliff. With this in mind, we can assume that the distance between Ball X and Ball Y is 4.0m.

Total Distance = Ball Y - Ball X

Total Distance = 4.0 m - 0 m

Total Distance = 4.0 m

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.
