The best example of an elastic collision from above is that of a cart which rammed into another one and they are now pushed apart. The last option is the correct answer. An elastic collision occurs when two objects bounce apart when they collide thus, preserving kinetic energy and momentum.
Answer:
I1 = ε/R1
I2 = ε/R2
I3 = ε/R3
Explanation:
From the image, we see that the resistors are connected in parallel. This means that the voltage passing through them is the same.
Now, formula for current is; I = V/R
In this case, V which is voltage is denoted by ε.
Thus;
I1 = ε/R1
I2 = ε/R2
I3 = ε/R3
Answer:
58.703 ft/centuri
Explanation:
Length of the hair grow, l = 0.49 mm
Time to grow, t = 1 day
Convert mm into feet.
We know that, 1 mm = 0.00328 feet
So, 0.49 mm = 0.49 x 0.00328 = 0.0016072 ft
Convert day into century.
We know that, 1 century = 36525 days
So, 1 day = 1 / 36525 centuri
growth rate of hair =
= 58.703 ft/centuri
Answer:
In our project, we have a class one lever that is hit by a pulley basket, thus letting a ball roll down.
Explanation:
Answer:
It is the amount of thermal energy (heat) needed to raise the temperature of 1kg of a substance by 1°C.
*It is important to state that it is per kg because of the word "specific".
