Atoms of the same element but with different atomic masses are called isotopes. They possess a different atomic mass, due to the indifferent number of neutrons that the atoms of a given element have.
Answer:
v = 16 m/s
Explanation:
Given that,
Distance, d = 400 m
Time taken, t = 25 s
We need to find the speed of the horse. Speed is equal to distance covered divided by time taken. So,
So, the speed of the horse is 16 m/s.
Answer:
Is removed from the atmosphere by photosynthesis.
Explanation:
The carbon dioxide (CO2) is presented in the atmosphere and its cycle began with it's incoming by respiration, combustion of fuels and decomposition. The autotrophs, which realize photosynthesis, use CO2 as fuel to produce their food with Sun rays.
The CO2 comprises about 0.3% of the atmospheric gases, and in the past few years, its input is being higher than its removal of the atmosphere, which is aggravating the greenhouse effect. Besides, the atmosphere of Venus has higher levels of CO2.

Answer:
Some substances can change from the solid state to the gas state without ever becoming a liquid. During this process, known as sublimation, the sur- face particles of the solid gain enough energy to become a gas.When dry ice becomes a gas, it absorbs thermal energy from water vapor in the air.
