Answer:
Explanation:
Find the final velocity at which it struck the ground by using the kinetic energy formula.
Now use kinematics to solve for the vertical displacement. We were given the initial velocity and acceleration can be assumed to be 9.8
Δy = 13.6 meters
I don't know why the answer is D , because I can't see the list of choices.
The only way to get 8.0 Amps is by making a serious mistake.
The current in the second picture is 4.0 Amps.
If the resistors are identical, then the effective resistance of
two resistors in parallel is 1/2 the resistance of each one.
The resistance in the second picture is 1/2 the resistance
in the first picture.
Current = (voltage) / (resistance)
Cutting the resistance in half causes the current to double.
If the current was 2.0 Amps in the first picture, it's 4.0 Amps
in the second picture.
The answer is 1000/20. Or that’s what I’m guessing. Lol
115.35 ft
Set the proportion up 37.50/105.50 = 41/x and solve for x
D) decreasing the temperature lowers the average kinetic energy of the reactants.
