There are two equal forces of gravity between the Earth and the Moon.
One force pulls the Moon toward the Earth.
The other force pulls the Earth toward the Moon.
If only this gravity suddenly switched off, then the moon would
continue to orbit the Sun, very much as it does now.
If ALL gravity suddenly switched off, then . . .
-- the Moon would stop orbiting the Earth and would sail away, in
a straight line and at the speed it had when gravity disappeared;
-- the Earth would stop orbiting the Sun and would sail away, in
a straight line and at the speed it had when gravity disappeared;
-- all the gases surrounding the Earth ... which we call "air" ... would
start drifting away, and expanding into a giant cloud of gas, and stop
being an atmosphere;
-- the Sun would completely fall apart, expand into a giant cloud of gas,
and stop being a star.
The terminology is somewhat arbitrary, however, In this case, you intentionally alter the angle, which then determines the resulting distance. The presumption of the experiment is that distance is DEPENDENT on the angle. The dependent variable will be the how far the rock went. The dependent variable is the variable that you are testing. The first sentence of description indicates that the experiment is to determine launch Θ vs range.The largest range value is to be determined, so the range is plotted on the Y-axis. Angle Θ is plotted on the X-axis. The distance depends on the launch of the angle so the answer will be (D) how far the rock went. It is the dependent variable.
Answer:
The minimum uncertainty in the velocity is 232.57 m/s.
Explanation:
Given that,
Location of a particle with uncertainty = 0.13 nm
Mass of particle
We need to calculate the minimum uncertainty in the velocity
Using heisenberg's uncertainty principle,
Put the value into the formula
Hence, The minimum uncertainty in the velocity is 232.57 m/s.
Answer:
c
Explanation:
electronic balance must always be at zero to prevent errors in measured value
Answer: they used seasonal wind, temperature changes, they also used the flooding of rivers. all these are used to tell time
Explanation: the seasons change the climate of the area
