1 answer:
When you turn on a battery-operated device, an electrical circuit is closed.
Explanation:
A circuit works, only when it is closed. When we turn on the battery-operated device, the circuit is closed & complete. Hence, the current will flow across the circuit.
Only closed circuits work (current flows through them). No current can flow in an open circuit.

Answer: the maximum heigth of the stadium at ist back wall is 151.32 ft
Explanation:
1. use the position (x) equation in parobolic movement to find the time (t)
565 ft = [frac{176 ft}{1 s\\}[/tex] * cos (35°) * t
t= 3.92 s
2. use the position (y) equation in parabolic movement to find de maximun heigth the ball reaches at 565 ft from the home plate.
y= [[frac{176 ft}{1 s\\}[/tex] * sen (35°) * 3.92 s] -
y= 148.32 ft
3. finally add the 3 ft that exist between the home plate and the ball
148.32 ft + 3 ft = 151.32
