Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
Answer:
C - higher volume
Explanation:
The pitch or frequency of sound that an object can produce depends upon its size and configuration . The shape of hand of all are same so the frequency of sound produced by hands of all will be almost same . Hence frequency of sound produced by the hands of Anand and Kumar would have been almost the same .
But the intensity of sound produced by them would have been different . Intensity represents energy a sound carries . Hard hitting clap will produce sound of higher intensity . Intensity of sound is also called high volume sound . So Kumar's clap will carry greater energy and hence greater volume of sound .
There are things like comets, asteroids, meteoroids, satellites, planets, etc. move around the sun.
Explanation:
- The solar system is made up of not only planets and its satellites, but there are also other things which move around the sun.
- Those are like comets, asteroids, and meteoroids.
- Asteroids are also called mini planets, there are bigger ones too and they are called planetoids. The orbit the sun in their belt called asteroid belt situated in between the orbits of Mars and Jupiter.
- Comets appear like snowballs which contain frozen gases, dust and rock which orbits the sun.
- Meteoroids are the metallic or rocky body found the outer space. It is smaller than the asteroids and micro-scale meteoroids are the space dust.

Answer:a) Water is relatively resistant to an increase in temperature
Explanation:
Water has relatively high heat capacity i.e. it requires high amount of heat to raise a little increase in temperature.
Heat capacity is defined as ability of molecule to absorb heat . Mathematically heat capacity is defined as
