<h2>Answer:</h2>

The correct answer is option A which is mass.

<h3>Explanation:</h3>

Inertia is terminology which is most commonly used in the physics. It is the measure of the resistance provided by the object in response to change in its speed or velocity.
According to the first law of motion, an object remains in the rest or in continues motion state unless they experience a force on it.
And every action has a reaction.
So when a force is applied on the moving object, it resists to change its state. That resistance is inertia.
Inertia of an object is directly proportional to mass of the object.
Hence option A is correct one.

Answer: Inertia is based only on an object’s mass.

Explanation:

Any physical object's resistance towards any change in its velocity is known as inertia.

Therefore, more is the mass of an object, the more inertia will be there.

Thus, we can conclude that inertia is based only on an object’s mass and not on velocity.

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the _________ group

zloy xaker [14]

Answer:

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the <u>phosphate</u> group attached to the 5' carbon atom of the sugar portion of a nucleotide and the <u>hydroxyl</u> group attached to the <u>3'</u> carbon atom

Explanation:

Nucleic acids are polymers formed by a phosphate group, a sugar (ribose in RNA and deoxyribose in DNA) and a nitrogenous base. In the chain, the phosphate groups are linked to the 5'-carbon and 3'-carbon of the ribose (or deoxyribose) and the nitrogenous base is linked to the 2-carbon. Based on this structure, the nucleic acid chain orientation is identified as the 5'-end (the free phosphate group linked to 5'-carbon of the sugar) and the 3'-end (the free hydroxyl group in the sugar in 3' position).

Problem 4

Hunter-Best [27]

<h3>Answer:</h3>

1.93 g

<h3>Explanation:</h3>

<u>We are given;</u>

The chemical equation;

2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(l) ΔH = -3120 kJ

We are required to calculate the mass of ethane that would produce 100 kJ of heat.

From the equation given;

2 moles of ethane burns to produce 3120 Kilo joules of heat

Therefore;

Number of moles that will produce 100 kJ will be;

= (2 × 100 kJ) ÷ 3120 kJ)

= 0.0641 moles

But, molar mass of ethane is 30.07 g/mol

Therefore;

Mass of ethane = 0.0641 moles × 30.07 g/mol

= 1.927 g

= 1.93 g

Thus, the mass of ethane that would produce 100 kJ of heat is 1.93 g

Two solid blocks are HEATED to the temperatures show. The blocks are placed so they touch. Which diagram shows the DIRECTION HEA

Setler [38]

Answer:

Heat flows from the block at high temperature to the one with lower temperature

Explanation:

The direction of heat flow is from a body at higher temperature to one with a lower temperature.

Temperature gradient determines the way and manner in which heat is dissipated.
As a system tend to increase entropy, it ensures that heat moves from hotter body to a colder body.
Heat movement here is by conduction as the body touches.
When both bodies reaches the same temperature, thermal equilibrium is established.
