 use the different characteristics of water such as freezing and boiling points, waters density, or using your five senses. Smell it, but don't taste it, feel it, listen to it. It might crackle or pop if it has carbon.

I know that density of water is 1000kg per cubic meter or 1g per 1ml
I would take beaker and scales.
1) I would measure liquid's weight (in g)
2) measure volume (in mL)
3) divide weight by measure
4) if would get 1 as result - it's water
5) if it's above or below 1 - it's not the water

A car accelerates at 3 m/s*2. Assuming the car starts from rest, how much time does it need to
uranmaximum [27]
<h3><u>Given</u><u>:</u><u>-</u></h3>

Acceleration,a = 3 m/s²

Initial velocity,u = 0 m/s

Final velocity,v = 12 m/s

<h3><u>To</u><u> </u><u>be</u><u> </u><u>calculated:-</u><u> </u></h3>

Calculate the time take by a car.

<h3><u>Solution:-</u><u> </u></h3>

According to the first equation of motion:

v = u + at

★ Substituting the values in the above formula,we get:

⇒ 12 = 0 + 3 × t

⇒ 12 = 3t

⇒ 3t = 12

⇒ t = 12/3

⇒ t = 4 sec

A wagon has a mass of 100 grams and an
olga2289 [7]

Answer:

Net force on the wagon is 200 N

Explanation:

As we know by Newton's II law that net force on the system of mass is given as product of mass and acceleration

Here we know that

mass = 100 kg

a = 2 m/s/s

now we have

F = ma

F = (100)(2)

F = 200 N

Does the gas have a well defined structure

Why does Energy appear continuous in everyday life?
lara31 [8.8K]

Answer:

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted. Nothing happens to the energy. It does not change form, since energy has no form. ... If the energy was moving, it gets stored or re-transmitted elsewhere. Using energy means controlling its movement, rather than consuming it.
