A vacuum: the motor starts the fan that causes the vacuum to have suction and the motor is what moves the bristles
A blender: the motor is what makes the blade spin
Hope I helped!
Explanation:
Given parameters:
Wavelength of photon = 1.95 x 10⁻¹¹m
Unknown:
Frequency of the wave = ?
Energy of the photon = ?
Solution:
The frequency and wavelength of a wave are related by the expression;
C = Fλ
C = speed of light = 3 x 10⁸m/s
F = frequency
λ = wavelength
Insert the parameters and solve;
3 x 10⁸ = F x 1.95 x 10⁻¹¹
F = = 1.54 x 10¹⁹Hz
Energy of the photon is related to frequency using the expression below;
E = hF
h is the Planck's constant = 6.634 x 10⁻³⁴m²kg/s
Insert the parameters and solve;
E = 6.634 x 10⁻³⁴ x 1.54 x 10¹⁹ = 1.02 x 10⁻¹⁴J
When mass is constant, Force equals mass times acceleration. The answer is A.
Pure substances are defined as substances that are made of only one type of atom or only one type of molecule (a group of atoms bonded together).
Answer:
Propanganda
Explanation:
Propanganda can be defined as information that is often of a misleading nature. It is biased and often used to promote a political point of view.
It is the spreading of lies, half truths with the sole purpose of influencing public opinion. Propanganda works by
playing upon the fears, angers and emotions of people. It raises in people, the feelings of unpleasantness and also disgust.
