Which of the following supports the theory of continental drift?The depth of the oceans
The climate of the South American continent
The size of glaciers in Alaska
The fossil record

Answers

Answer 1
Answer: The answer to this question is the fossil record because they found fossils in different continents because of continental drift
Answer 2
Answer: Hello :) So the continental drift theory is basically saying that the continents were once attached in a big mass of land and drifted apart over time. The depth of the oceans don't really have anything to do with this. Neither does the climate in South America or the size of glaciers. Fossils of the same kind however, were found in several continents. This supports the theory that animals once roamed around in that area when the continents were attached. Hope this helps. :D

The longest chain of atoms in a particular molecule consist of seven carbon atoms. Which name might this molecule be called?A. butane
B. ethylene
C. heptyne
D. Septane

Answers

Answer

Option C - Heptyne

Explanation

The longest chain of atoms in a particular molecule consists of seven carbon atoms. This molecule might be called heptane (C7H16). It can be a straight chain or can be branched. Its structure is -C-C-C-C-C-C-C-. Carbon completes its four bonds by combining hydrogen atoms. Hydrocarbons are named according to the carbon atoms. One carbon atom is methane, two containing is ethane, three is propane, four is butane, five is pentane, six is hexane, seven is heptane, eight is octane, nine is nonane and ten is decane.

Suppose you are riding in a car. Describe your motion relative to the car, the road and the sun

Answers

The relative motion of a person riding in a car has been stationary with car, uniform constant with road, and sun.

The motion has been defined as the change in position of an object with respect to another.

Relative motion

The relative motion has been observed by considering an object at rest and assuming the displacement with the another.

The relative motion has been assessed from car, thus car has been assumed at rest.

  • The relative motion of the person ridding in the car with respect to the car has been stationary. It has been no motion of person with respect to car.

  • The relative motion of the person riding the car with the road has been constant. The car has been moving along the road in the motion.

  • The relative motion of person riding car with the sun has been constant as there has no change in the motion of the sun as soon as we are riding in straight path.

Thus, the relative motion of a person riding in a car has been stationary with car, uniform constant with road, and sun.

a cadillac escalade has a mass of 2.569 kg if it acceleratesat 4.65m/s what is the net force on the car

Answers

The Net Force is equal to the mass of the Object multiplied by the amount of Acceleration. Therefore, this creates an equation which looks like this:

F = Mass * Acceleration
F = 2.569 kg * 4.65 m/s
F = 11.95 N

Hopes this helps! 

What causes matter to exist in three different states​

Answers

NOT 100% SURE

Thermal Energy..?

When I think of three states of matter I think of water as an example:

• Adding extreme heat to the liquid form of water can turn it into gas.

• Adding heat to ice can turn it into the liquid form of water.

• Freezing the liquid form of water can turn it into ice.

I would say temperature (thermal energy) has an effect of the different states of matter.

Insulator, to be a conductor some form of heat energy would have to pass through.
Insulator because it does not let heat pass through
