Which tools would sara us to find an irregularly shaped objects mass and volume A. a meter stick , a ruler , and water

1 answer:

4 0

I think it's D. Usually, to find the volume of an irregularly shaped object, you put it in water with a labeled beaker to measure how much the water rises. The balance would be used to measure the mass in grams.

In which situation is maximum work considered to be done by a force

Katena32 [7]

Answer:

Work done is maximum when the movement of object is in line and direction of force.

Work done is maximum, when displacement takes place along the direction of force.

Work done is given by the equation

W = F.S

<em> W = F. S cos Θ</em>

What is the mass of a sample of water that takes 2000 kJ of energy to boil into steam at 373 K? The latent heat of vaporization

GREYUIT [131]

Answer : The mass of a sample of water is, 888.89 grams

Explanation :

Latent heat of vaporization : It is defined as the amount of heat energy released or absorbed when the liquid converted to vapor at atmospheric pressure at its boiling point.

Formula used :

$q=L\times m$

where,

q = heat = 2000 kJ = $2\times 10^6J$ (1 kJ = 1000 J)

L = latent heat of vaporization of water = $2.25\times 10^6J/kg$

m = mass of sample of water = ?

Now put all the given values in the above formula, we get:

$2\times 10^6J=(2.25\times 10^6J/kg)\times m$

$m=0.88889kg=888.89g$ (1 kg = 1000 g)

Therefore, the mass of a sample of water is, 888.89 grams

Iteru [2.4K]

Answer:

What part of the light wave is related to the brightness of the light?

Amplitude

The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength

The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.

lord [1]

Answer:

The work done is equal to zero = 0

Explanation:

Let us remember that the definition of physical work is given by the product of force by the displacement of the body.

$Work=F*d\\\\where\\F= force [N]\\d=distance [m]\\replacing\\Work=1115*(0) = 0$
