Answer:
is the first confirmed terrestial planet to have been discovered outside the solar system by the kepler space telescope
Explanation:
The roller coaster is moving in a circular path, so the force that must be computed is the centripetal force. The centripetal force is the force acting on an object undergoing circular motion and is directed towards the center of the circular path. This is computed using:
F = mv²/r
F = (500 * 18²) / 12
F = 13,500 N
Now, at the bottom of the track, the track is also supporting the weight of the car and its passengers, which is:
W = mg
W = 500 * 9.81
W = 4,905 N
The total reactive force exerted by the track to counter the centripetal force and the weight of the car is:
F = 13,500 + 4,905
F = 18,405 Newtons
1-California
2-Florida
3-Texas
4-New York
So I’m sure that to most visited state in the USA is California
Answer:
Explanation:
Given
Initial velocity of ball 
height of window 
Using Equation of motion
where u=initial velocity
t=time
a=acceleration
As ball is already is at a height of 20 m so
(b)highest point is obtained at v=0
where
v=final velocity
u=initial velocity
a=acceleration
s=displacement
Highest Point will be 
(c)Time taken when the ball hit the ground i.e. at Y=0
impact velocity
