The same way as the trees with green leaves. Through photosynthesis :)
Answer:
A. Always true
Explanation:
This is because, the buoyancy force is always present whenever and object is placed in a fluid. The magnitude of this buoyancy force is always equal to the weight of the fluid displaced by the object according to Archimedes' principle. This principle is true irrespective of whether the object floats or not. When any object is inserted in a fluid, the buoyancy force is always present irrespective of whether it floats or not.
Explanation:
The inertia of a 4 kg mass is four times as great as a 1 kg mass.
Solution:
Make an Observation - An indoor plant in a dark room withers faster than the same plant in a room with ample sunlight.
Ask a question- Why do certain indoor plants die faster based on where they are placed in the house?
State a hypothesis- Sunlight is probably essential for plants to grow and live.
Run an experiment- Get two potted plants. Cover one with black paper. Place both plants outside in sunlight. See what happens to each plant after one week.
Analyze the results-The plant in the pot with black paper withered. The other plant was healthy.
Communicate the results to others - Plants need sunlight to make food so they can live.
Who pays the income tax, the payroll tax, the estate and gift taxes? Who
bears the burden of the gasoline and tobacco taxes? If Congress were to
raise this tax rate, or lower that tax deduction, who would gain and
who would lose? The outcomes of the political battles over changes in
the tax system often hinge on the answers to such questions. This paper
will discuss the economic consequences of taxation and the factors that
influence where the burden of various taxes really falls. It will review
some of the discussions in the economic literature. Finally, it will
suggest that a shift to a markedly different type of tax system would
benefit all players in the economy.
