Answer:

A. Density of object = 0.86 g/mL

B. The object will float in the water.

Explanation:

The following data were obtained from the question:

Volume of water = 6.2 mL

Mass (m) of object = 1.2 g

Volume of water + Object = 7.59 mL

Density of object =?

Density of water = 1 g/mL

Next, we shall determine the volume of the object. This can be obtained as follow:

Volume of water = 6.2 mL

Volume of water + Object = 7.59 mL

Volume of object =?

Volume of object = (Volume of water + Object) – (Volume of water)

Volume of object = 7.59 – 6.2

Volume of object = 1.39 mL

Therefore, the volume of the object is 1.39 mL

A. Determination of the density of the object.

Mass (m) of object = 1.2 g

Volume (V) of object = 1.39 mL

Density (D) of object =?

Density = mass /volume

Density = 1.2/1.39

Density of object = 0.86 g/mL

B. Determination of whether the object will float or sink.

Density of object = 0.86 g/mL

Density of water = 1 g/mL

From the above, we can see that the density of water is greater than that of the object. This implies that the object is lighter than water. Therefore, the object will float in the water.

Photon energy is proportional to which of the following quantities? speed of light in a vacuum frequency of the light emitting t
charle [14.2K]

Answer:

The energy of the photon is directly proportional to the  frequency of the light emitting the photon.

Explanation:

Energy of the photon is given by expression:

E=h\times \nu=\frac{hc}{\lambda }

E = Energy associated with the photon

\nu  =  frequency of the light

h = Planck's constant =6.626\times 10^{-34} J s

c = speed of the light in vacuum = constant

\lambda =Wavelength of the photon

E\propto \nu

The energy of the photon is directly proportional to the  frequency of the light emitting the photon.

Which organelle do you think is the most important and why
vekshin1
 <span>All organelles are important. However, to answer your question...the most important organelle in my opinion is the nucleus. The nucleus is like the floor general or the point guard on a basketball team. It contains most of the cell's DNA, directs and controls cell function through gene expression, and mediates DNA replication during cell cycles. 

Note: Not all cells have nuclei. An example of this are the red blood cells, that lack nuclei as well as mitochondria.</span>
