Answer:
yes
Explanation:
when we throw a ball upwards, it will eventually come back to us because of force.
Answer:
Spectra type M
Explanation:
mass spectrum is simply an intensity vs. m/z (mass-to-charge ratio) plot representing a chemical analysis. Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass (more correctly: mass-to-charge ratio) in a sample. It is usually acquired using an instrument called a mass spectrometer. Not all the mass spectra of a given substance are same.
Plants that died a few thousand years ago.
Answer:
Equations for speed, velocity and acceleration depend on change of position over time. Average speed uses the equation "speed equals distance traveled (d) divided by travel time (t)," or average speed = d ÷ t. Average velocity equals speed in a direction
We also learned that speed is a scalar quantity, which is one that requires only a magnitude, while velocity is a vector quantity, which is one that requires a magnitude (also mph) and a direction. The rate of change for velocity is acceleration, which is measured in displacement over time over time (e.g., m / s^2).

The work done by the two forces in moving the chandelier to the given distance is 5,091.2 J.
<h3>
Work done by a single force on the chandelier</h3>
The work done by a single force on the chandelier is determined by taking the net horizontal force applied on the chandelier over the given distance.
where;
is frictional force = 0 (smooth surface).
<h3>Work done by the two forces</h3>
When the two forces combine to pull the chandelier, the total work done will be shared by the two forces.
Thus, the work done by the two forces in moving the chandelier to the given distance is 5,091.2 J.
