Answer:
when the ball is at its highest in the air.
Explanation:
I don't know for sure, but when the ball is in the air it has potential energy to fall(or something like that).
Answer:
45 degrees
Explanation:
The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degrees.
(a) The equivalent resistance of the circuit is 0.52 ohms.
(b) The total electric current that runs through the circuit is 40.38 A.
(c) The value of the electric current passing through the resistor of 1.0 Ohm is 21 A.
(d) The power dissipated through the 8.0 Ohm resistor is 55.13 W.
<h3>
Equivalent resistance of the circuit</h3>
The equivalent resistance of the circuit is calculated as follows;
1/R = 1/(1 + 1) + 1/(2 + 2 + 2) + 1/(6) + 1/(2) + 1/8 + 1/8 + 1/6 + 1/6
1/R = 1/2 + 1/6 + 1/6 + 1/2 + 1/8 + 1/8 + 1/6 + 1/6
1/R = 1 + 2/3 + 1/4
1/R = 23/12
R = 12/23
R = 0.52 ohms
<h3>Total current through the circuit</h3>
V = IR
I = V/R
I = 21/0.52
I = 40.38 A
<h3>Current through 1 ohm resistor</h3>
V = IR
I = V/R
I = 21/1
I = 21 A
<h3>Power dissipated through 8 ohm resistor</h3>
P = V²/R
P = (21)²/8
P = 55.13 W
