Answer : Mass
Explanation : An object's resistance to change in motion is solely dependent on the mass of the quantity. The tendency to resist the change in motion is called as inertia. Which is highly influenced by the factor called "mass" of the object. The mass of the quantity will decide the direction for change in the motion of a particular object.
the bell, the balloon
contracted
expanded
When the pump removed the air in the bell, the balloon expanded.
Option: B
Explanation:
In order to construct our own environment in the glass jar known as bell jar system, which can be used to explore and consider our larger environment on Earths, for an instance. Here a glass jar that hinges on an airtight rubber basis i.e seals appropriately. At the top of the jar, a bung is connected to it which passed via a metal tube. It has an adjacent flexible tube that goes to a hand vacuum pump and the best hand-powered pump was made with a wine preserver.
When the pump extracts the air from the bell jar, the pressure inside the balloon naturally decreases. The balloon usually has a air pressure around it, which restricts its size, but when this air is extracted and the pressure around it decreases the gas in the balloon will expand and the balloon seems to be inflating. When you release the air back into the bell jar, it will once again compress back to its actual size.
B. There will be a decrease in the population of snakes in the ecosystem.
C. The nutrition of the soil in the ecosystem will decrease.
D. More type of plants will begin growing in the ecosystem.
The mass of the piece of copper will be 130 kg. In the International System of Units (SI), the kilogram is the unit of mass.
Mass is a numerical measure of inertia, which is a basic feature of all matter. It is, in effect, a body of matter's resistance to a change in speed or position caused by the application of a force.
The energy absorbed as;
Hence, the mass of the piece of copper will be 130 kg.
