Explanation :
The gravity of the Sun causes the planets to move in a circular path. This is because of Newton's first law of motion.
According to Newton's first law, the body will remain at rest or in uniform motion untill external unbalanced force acts.
There are two forces acting on planets i.e. gravitational force and inertia of their orbits. So, form Newton's first law the planets keeps on moving in a circular path.
water freezes inside a rock, causing it to break
oxygen reacts with the chemicals in rock
rocks break from repeated exposure to the Sun's heat
Answer: water freezes inside a rock, causing it to break
Weathering is a natural process in which the rocks break into pieces or sediments by the action of wind, water and chemical agents. Frost wedging is a physical weathering process. It occurs in an area where temperature fluctuations occurs due to change in the climatic conditions. This occurs due to rapid heating and cooling. The rocks lying in a cold environment, the water residing in the rocks gets freezed. The water in ice form that is solid form acquire more space than in liquid form, therefore, the developed ice will affect the physical structure of the rock. The formation of ice results in the development of break or crack in the rock typically in the shape of a wedge and thus the phenomena is called as frost wedging.
Hence, frost wedging happens when water freezes inside a rock, causing it to break.
Answer:
Frost wedging happens when water freezes inside of a rock, causing it to break
b. potentiometer
c. voltmeter
d. galvonmeter
e. batterymeter
The device used to measure a potential difference in a circuit is called a voltmeter. The correct option is c.
The tool used to measure the potential difference between two locations in an electric circuit is called a voltmeter. A voltage meter usually referred to as a voltmeter, is a device that measures the voltage, or potential difference, between two points in an electrical or electronic circuit.
Both of these devices are employed in electric circuits, however, the voltmeter is primarily used to measure the voltage or emf across two points in an electric circuit, whilst the ammeter is mostly used to measure the flow of current.
Depending on the measurement, voltmeters are divided into two categories: DC voltmeters and AC voltmeters.
Therefore, the correct option is c. voltmeter.
