If there's nothing else connected to the battery except the 3-ohm resistor, then the question is defective and the correct answer is not on the list.
With 12v connected across the resistor, the current through the resistor is
I = (E/R) = (12/3) = 4 Amperes.
The power generated inside a resistor is
P = (E x I) = (12v) x (4 A) = 48 watts
Clues or evidence
Im pretty sure its evidence though
2nd egg experienced more impulse
Hope this helps! :)
Answer:
U = 9.1 m/s
Explanation:
from the question we are given the following
time (t) = 1.8 s
angle = 23 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
let us first calculate the initial velocity (u) which too the first ball to its maximum height from the equation below
v = u + 0.5at
- The final velocity (v) is zero since the ball comes to rest
- The time (t) it takes to get to the maximum height would be half the time it is in the air, t = 0.5 x 1.8 = 0.9
therefore
0 = u - (0.5 x 9.8 x 0.9)
u = 7.9 m/s
for the second ball to get to the maximum height of the first ball, the vertical component of its initial velocity (U) must be the same as the initial velocity of the first ball. therefore
U sin 60 = 7.9
U = 7.9 ÷ sin 60
U = 9.1 m/s
Answer:u=42.29 m/s
Explanation:
Given
Horizontal distance=167 m
launch angle
Let u be the initial speed of ball
