the answer is true because i think its true not 100 percent sure
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,
From the solubility rules, both reactions 1 and 2 lead to precipitates.
<h3>What is a precipitate?</h3>
The term precipitate refers to the solid that separates out of the reaction mixture . We know that the solubility of a substance in water is predicated on the solubility rules.
1) The reaction here is;
Fe(NO3)3(aq) + 3NaOH(aq) ------> Fe(OH)3(s) + 3NaNO3(aq) - The precipitate is Fe(OH)3 because only the hydroxides of group 1 elements are soluble in water.
2) The reaction is;
Pb(NO3)2(aq) + 2KI(aq) ----->PbI2(s) + 2NaNO3(aq) - The precipitate is PbI2 because most iodides are soluble except the iodides of Ag+, Hg+2, and Pb+2
Complete Ionic equation;
Pb^2+(aq) + 2NO3^-(aq) + 2K^+(aq) + 2I^-(aq) ------> PbI2(s) + 2NO3^-(aq) + 2K^+(aq)
Net ionic equation;
Pb^2+(aq) + 2I^-(aq) ------> PbI2(s)

The tilt of the moon's axis does not allow for monthly alignment, so the lunar and solar eclipse do not happen every month.
<h3>How do the lunar and solar eclipse occur?</h3>
- For the occurrence of lunar and solar eclipse, the sun, moon and the earth must remain in a plan and along a straight line.
- When the earth appears in between the sun and the moon, lunar eclipse occurs.
- When the moon appears in between the sun and the earth, solar eclipse occurs.
- The moon and earth are rotating not only around the sun, but also around the black hole of Milky way galaxy.
- So they are not present in a plan as well as in a straight line in every full moon and new moon time.
Thus, we can conclude that the option D is correct.

Answer:
Explanation:
First Law of Motion: Law of Inertia.
An object in motion stays in motion unless an outside force is applied to the object to make it stop, and an object at rest will stay at rest unless an outside force is applied to make the object move.
Second Law of Motion: Law of Acceleration.
It explains the equation with force. Force is equal to mass times its acceleration. It also explains how mass can affect acceleration. They are inversely proportional. Mass can decrease acceleration.
Third Law of Motion: Law of Action-Reaction.
For every action that occurs on an object, an opposite reaction occurs. This explains how forces act in pairs, there is an action force and a reaction force.
