Answer:
In mathematics, the difference of two squares is a squared (multiplied by itself) number subtracted from another squared number. Every difference of squares may be factored according to the identity. in elementary algebra.
Explanation:
Answer:
The time period of the empty car will be "1.00 s".
Explanation:
The given values in the question will be:
Mass,
m = 250 kg
Loaded car's time period will be:
T = 1.08 s
Shock absorbers compression,
x = 4 cm
or,
= 0.04 m
Now,
Weight of passengers will be:
⇒
The spring constant of shock absorbers will be:
⇒
As we know,
Time period,
On substituting the values, we get
(Total mass of car as well as its passengers)
Now,
The mass of the empty car will be:
⇒
hence,
The time period of empty car will be:
⇒
or,
the answer is c because it is the 3rd step in the scientific analysis steps
