Answer:
Explanation:
I assume you are asking for the acceleration of the ball, not the velocity (in fact, the velocity is already given).
The acceleration is:
where in this case we have:
v = 24 m/s is the final velocity
u = 0 is the initial velocity
t = 8 s is the time interval for the velocity to change
Solving the equation,
45-50% of the moon is lit up.
ANSWER
R = 3 Ω
EXPLANATION
This is a circuit made of a power source and a resistor. To find the resistance on the resistor, we have to use Ohm's Law,
If we plot the measures in a current-voltage graph, the slope of that graph is the inverse of the resistance,
The slope of the line of best fit is approximately 1/3, which means that the resistance is 3 Ω.
If we apply Ohm's Law to get the resistance for each pair of measures (V, I), we should obtain a value around 3:
• For (6, 2):
• For (8, 2.7):
• For (10, 3.3):
• For (12, 4):
• For (14, 4.7):
Hence, the resistance is 3 Ω.
<span>Audible beats are formed by the interferences of two waves in which are from the slightly different frequencies which is letter a. It is because having two waves that consist of slightly different frequency causes or produce the audible beats to be formed in which they are beats that causes sound to be either loud or soft.</span>
