The metric unit of volume is the liter.

1 cubic meter = 1,000 liters

A liter looks a lot like a quart. It's only about 6% bigger than a quart.

The larger-style water bottle that you might buy at the Sebm Lebm store
and carry with you when you're walking is 16.9 ounces ... that's 1/2 liter.

Those big heavy plastic soda bottles that hang around in the fridge
for several days are 2-liter bottles.

There are two particular cases, the first is when Object A is attracted to the neutral wall. This would indicate that the object is not neutral, as there is an attraction.

At the same time we know that Object A is attracted to an object B. And therefore, the load of A must be opposite to that of B. Remember that opposite charges attract each other. If the charge of object B is positive, then the charge of object A will be negative.

Option B is correct: It has a negative charge.

Answer: The end point of a spring oscillates with a period of 2.0 s when a block with mass m is attached to it. When this mass is increased by 2.0 kg, the period is found to be 3.0 s. Then the mass m is 0.625kg.

Explanation: To find the answer, we need to know more about the simple harmonic motion.

<h3>What is simple harmonic motion?</h3>

A particle is said to execute SHM, if it moves to and fro about the mean position under the action of restoring force.
We have the equation of time period of a SHM as,

$T=2\pi \sqrt{\frac{m}{k} }$
