1. A rock sample has a mass of 16 grams:
and a volume of 8 cubic centimeters.
When the rock is cut in half, what is
the volume and density of each piece?
(1) 8 cm3 and 0.5 g/cm3
(2) 8 cm² and 1.0 g/cm3
(3) 4 cm' and 2.0 g/cm3
(4) 4 cm3 and 4.0 g/cm3
1

Answers

Answer 1

Answer:

(3) 4 cm' and 2.0 g/cm3

Explanation:

Given:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³

HELP PLEASE!!!explain how Earth is heated through conduction​

Answers

As it's known conduction needs a medium for heat transfer and during the day, sunlight rays pass through the Earth's atmosphere and near the earth's surface is where most heat transfer by conduction occurs since air is a poor conductor. Thus, the sunlight hits the earth's surface(ground) and in turn heats the air above it and transfering the heat.

It must be known that conduction happens mostly near the earth's surface.

Answer:

Conduction is one of the ways that energy is transferred from the earth's atmosphere to the air. Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove.

Which statement is true about dichotomous keys?(1 point)

Dichotomous keys can only be used to classify organisms based on their habitats.

Dichotomous keys can only be used to classify organisms based on their observable traits.


Dichotomous keys can only be used if the name of the species is unknown.


Dichotomous keys can only be used if the name of the species is known.

Answers

The dichotomous key is a classification tool based on morphological characteristics. The correct option is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

What is a Dichotomous key?

A dichotomous key might be considered a significantly useful tool to classify organisms.

The key provides an easy and fast way for identification by describing different morphological observable traits, leading you to the correct taxonomic classification.

The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

Each time you choose an option, it leads you to the following description, which gets more specific each time.

Probably you might need an atlas or a dictionary to understand some of the technical terminologies.

You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.

The correct statement is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

One person pulls on a rope with a force of 400 N to the right. Another
person pulls on the opposite end with a force of 600 N to the left. What is
the net force?

Answers

600-400= 200N to the left.

Two forces are applied on the rope of the magnitude 400N to the right and 600N to the left, as a result of these forces the net force on the object will be 200N. Thus, the correct option is A.

What is Net force?

Net force is the resultant force of the total force which is being applied on an object. It is the sum total of the effect of all the forces on an object. Forces which are applied in opposite directions cancel out each other.

If the net force applied on an object is not zero, then it can be said that the object is not in equilibrium, and thus Newton's Second Law can be used to determine the motion of the object.

Here, two forces of different magnitudes and in opposite directions are applied on the rope to pull the rope. The forces are 400N to the right and 600N to the left.

As a result of these forces, the net force applied on the rope can be calculated by:

Net force = Difference between the forces applied in opposite directions or the sum of the forces which are applied in same direction

Net force = 600N (force applied to the left) - 400N (force applied to the right)

Net force = 200 N and the direction will be left as the magnitude is more in left direction than right

Therefore, the correct option is A.
