Answer: shrink and heat
Stars similar to our Sun use hydrogen as fuel, creating helium in the process of nuclear fusion.
Now when the hydrogen is used up, the core of the star reaches such a temperature that begins to transform the helium into carbon. That is, the core heats up more due to the continuous fusion reactions and shrinks because it will not have enough pressure to maintain its size.
According to geological data, oxygen production by photosynthetic microbes began about 2 billion years ago. This made it possible for oxygen to build up in the atmosphere, which eventually led to a switch from reducing to oxidizing circumstances.
A basic type of bacteria eventually evolved that could survive by using the energy from the Sun and the carbon dioxide in the water to produce oxygen as a byproduct. As a result, the atmosphere started to fill up with oxygen as carbon dioxide levels were falling.
Cyanobacteria underwent a stunning transformation at least 2.4 billion years ago, which was made possible by their evolution.
They evolved into the earliest photo-synthesizers on Earth, producing food out of water and solar energy, while also releasing oxygen in the process.
Therefore, living beings were able to breathe because of the oxygen in the early atmosphere.

The only right answer from these available options is a fault.
(B) exhaust
(C) oil filter
(D) tires
Answer:
Tires.
Explanation:
There are the few steps which are discussed below should be taken to increase or extend the life of tires.
(1) Avoid fast starts: Fast start of the vehicle will increase the pressure on the tires due to the friction between the tires and the road will decrease the life of tires.
(2) Avoid fast stop: Fast stop of the vehicle will also increase the pressure on the tires due to the friction between the tires and the road will decrease the life of tires.
(3) Avoid sharp turns: The alignment of the wheels and tires are in such a way that they work properly when vehicle is drive in a straight path but sharp turn will increase the uneven pressure on the tires will lead to decrease the life of tires.
Therefore, the life of tires can be extend by avoiding all the above mention actions such as fast stop, start and sharp turns.
The life of tires can be extended by avoiding fast starts, stops and sharp turns. These maneuvers cause excessive friction which leads to quicker deterioration. Suitable driving habits can extend the life of the tires.
You can extend the life of your tires by avoiding fast starts, stops, and sharp turns. When a driver performs a fast start, a large amount of friction is produced between the tires and the road, causing the tires to wear faster. The same goes for abrupt stops and sharp turns, which also produce an excess amount of friction, leading to a quicker deterioration of the tires.
Therefore, to extend the life of your tires, it is advisable to drive in a cautious and considerate manner, avoiding fast starts and stops and refraining from making sharp turns whenever possible.

6. 2017 Ω, about 2000 Ω.
7. no current is induced unless the field is changing
6. The relationship between power, voltage, and resistance is ...
P = V²/R
Rearranging gives
R = V²/P = (220 volt)²/(24 watts) ≈ 2016.667 Ω
The closest answer choice is 2000 Ω.
___
7.No current is induced in a stationary loop in a time-invariant magnetic field.
If something were changing, the direction of current induced would depend on whether the field is increasing or decreasing, and/or whether the loop is expanding or contracting.
The equivalent resistance of the input circuit is approximately 2028.33 ohms.
In this question, we are given the power input and the voltage input of a transformer, and we are asked to find the equivalent resistance of the input circuit. To find the equivalent resistance, we can use the formula:
Resistance = Voltage2 / Power
Using the given values of voltage (220 V) and power (24 W), we can substitute these values into the formula to find the equivalent resistance:
Resistance = (2202) / 24 = 2028.33 ohms
Therefore, the equivalent resistance of the input circuit is approximately 2028.33 ohms.

Why is gravity an example of scientific law?
Because it is a basic concept that defines a constant and universal behaviour of nature, gravity is seen as an illustration of a scientific law.
Scientific laws are succinct formulations that precisely explain a natural occurrence and are the result of in-depth observation and investigation. Einstein's theory of general relativity or Newton's law of universal gravitation both use the concept of gravity to explain how mass-containing objects interact with one another in space.
It offers a mathematical framework that enables researchers to perform precise projections and estimates about celestial body motion, the behaviour of things close to the surface of the Earth, and the structure of the cosmos.
The fact that gravity is recognised as a scientific rule is a reflection of the fact that it is widely accepted and has been shown to have practical applications.
