Scott needs to determine the density of a metallic rod. First, he should determine the mass of his sample on the laboratory balance. Second, he should measure the volume of his sample by water displacement. Finally, he can calculate the density by dividing mass/volume. 
Hope this helped ;)

Describe the concept that defines weather an object
xz_007 [3.2K]

An object has identity(each object is a distinct individual). An object has state(it has various properties, which might change). An object has behavior(it can do things and can have things done to it). This is a somewhat ordinary description of what an object is like.

Define neuron and nerve<br>cell​
san4es73 [151]

Answer: Hi!

A neuron is a basic working unit of the brain. Neurons are special cells designed to transfer information to other nerve, muscle, or gland cells. They are pretty cool - looking too! (A slightly irregular circular shape with branches reaching out from all sides.) A neuron is a nerve cell. Nerve cells are the way of communication in the nervous system.

Hope this helps!

If 40.0 kj of energy are absorbed by .500 kg of water 10 degrees c, what is the final temperature of the water?
anastassius [24]

To solve the problem, we must use the following equation:

Q=mC_s (T_f -T_i)

where

Q is the amount of heat energy absorbed by the water

m is the mass of the water

Ti and Tf are the initial and final temperature

Cs is the specific heat capacity of the water

The data we have in this problem are:

Q=40.0 kJ

C_s =4.186 kJ/kg^{\circ}C

T_i=10^{\circ}C

m=0.500 kg

Substituting the data into the equation and re-arranging it, we find

T_f = T_i + \frac{Q}{mC_s}=10^{\circ}+\frac{40.0 kJ}{(0.500 kg)(4.186 kJ/kg^{\circ}}=29.1^{\circ}C

So the final temperature of the water will be 29.1 degrees.

check the state of polarization of the room lights by looking at the room lights through one of the polarizers and rotating it t
maria [59]

Answer:

No, there wasn't any variation in the light intensity at 360 degrees.

During the rotation, rotating through an angle of 90° gradually brought the intensity to a maximum. Rotating by another 90° degrees brought the intensity to a minimum at some point. Rotating by another 90° brought it back to its maximum and then another 90° brought it to its initial intensity.
