alex41 [277]

Transformation 3 should Tracy removed from the list. Chemical energy transforms into gravitational potential energy.

<h3> What is the law of conservation of energy?</h3>

According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

Transformations that occur as an engine runs to power a car is;

1. Chemical energy of fuel transforms into thermal energy.

2. Thermal energy transforms into electrical energy used to lighten the bulb in a car.

3. Thermal energy transforms into kinetic energy to help to run the car.

Chemical energy transforms into gravitational potential energy is the incorrect energy transformation.

Hence, transformation 3 should Tracy removed from the list.

zhuklara [117]

Answer:

Star A is closer than Star B

Explanation:

As we know that in parallax method of distance measurement the angle subtended by the star when it covers a distance of one Parsec arc length, it is known as parallax angle

Here we can say

$angle = \frac{1 Parsec}{distance}$
