Let the total weight of the body be = x
Let the weight of the heart of the mammals be = y
Now the given percentage of 0.5 %, we will convert it into decimal form,
so this is equal to 0.005 in decimal form,
so the linear equation that gives the heart weight in terms of body weight will be,
y = 0.005x
The farther from earth's surface you are, the less gravitational attraction there is. So you will weigh less on a space ship because you have escaped the gravitational pull of earth. When you finally reach the moon, your weight is roughly one sixth what it is on earth.
It is the amount of work you have done in a certain amount of time. <span />

<em>All of the chemical elements in our solar system were forged in an ancient star that went supernova.</em>
Explanation:
This phrase means that the carbon, oxygen and nitrogen atoms in our bodies, as well as the other heavy elements in our solar system were created from previous stars over 4.5 billion years ago.
Star stuff got to Earth by means of a supernova explosion, which is an explosion of a massive star. This kind of stellar explosion creates a large cloud of gas and dust in space and the amount of material that the cloud is composed of depends on the type of supernova. The material from a supernova eventually disperses into interstellar space. The oldest stars consist of hydrogen and helium. Oxygen and the rest of the other heavier elements in the universe come from supernova explosions.
Therefore, <em>stars make heavy elements and later in their lives, they eject gas into the medium between stars so it can be part of subsequent stars, planets and eventually people.</em>
Answer : The correct option is, (B)
Explanation :
Electrical energy : It is defined as the movement of the electrons thought the wire.
Chemical energy : It is a type of energy which is stored in the bonds of a chemical compounds. During the chemical reaction, chemical energy is released in the form of heat.
Sound energy : It is a type of energy which is produced when an object vibrate.
Mechanical energy : It is a type of energy that can be used to do work.
The option A is incorrect because in this process, electrical energy being converted to the sound energy.
The option B is correct because in this process, electrical energy being converted to chemical energy. An oxidation-reduction reaction occurs in the storage battery.
The option C is incorrect because in this process, mechanical energy being converted to mechanical energy.
Hence, the option (B) A storage battery is charged using an electric current is an example of electrical energy being converted to chemical energy.
