Answer:
15.3 m/s
Explanation:
Given:
v₀ = 0 m/s
Δy = 12 m
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (9.8 m/s²) (12 m)
v = 15.3 m/s
Answer:
Explanation:
When an electric charge is immersed in an electric field, it experiences a force given by the equation
where
q is the charge
E is the magnitude of the electric field
In this problem, we have:
is the charge on the small piece of lint
is the force experienced by the charge
Therefore, we can find the magnitude of the electric field by re-arranging the equation and solving for E:
Answer:
c. The particle is moving in a positive direction, and its speed is decreasing.
Answer:
It is true.
Mass spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio of ions. The results are typically presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.
A mass spectrum is a plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds.
