Answer:
FALSE
Explanation:
The answer is false.
The speed of the sound in water is faster when compared to the speed of sound in air. This is because, the particles in air is loosely packed and are far from each other as compared to water or liquid.
The water particles are close to each other than air particles, so water particles are able to transmit the vibrations of the sound faster than the air particles.
Therefore sound waves travels faster in water than in air.
The answer is Kevin's weight may change between Planet X and Planet Y.
<u>Explanation</u>:
- The mass is the amount of matter contained in our body and it does not vary with other planets (remains constant). But the weight on the planet is the strength of gravity on the planet and result of mass which will vary with different planets. Your weight is a measure of the pull of gravity between the person and the planet.
- Every object in the universe will attract each other object with the same mass. When the gravity is high, your weight will be high because your weight will be depending on the gravitational pull of planets.
- For example, if an astronaut travels from Earth to Mars, his mass remains unchanged and he floats with the same size and mass but his weight will vary due to varying gravity. Thus your mass doesn't affect other planets it's only the weight that may change due to the varying gravitational pull or no gravity.
