Answer:
Time period = 2.5 sec
Frequency = 0.4 Hz
Amplitude = 0.26 m
Maximum speed = 0.65
Explanation:
No. of oscillations = 14
Time = 35 sec
(a). Time period of oscillation
T = 2.5 sec
This is the time period.
(b). Frequency
f = 0.4 Hz
This is the frequency.
(c). Oscillation from one side to another side is 65 - 13 = 52 cm = 0.52 m
Hence amplitude
A = 0.26 m
This is the amplitude.
(d). The maximum speed
2 × 3.14 × 0.4 × 0.26
0.65
Answer:
Frequency.
Explanation:
More energy = shorter wavelength = greater frequency
I think the first question is talking about the ionic compound Sodium sulfide and it’s formula is Na2S.
And for the second question, i’m pretty sure it’d be a positive charge
protons and neutrons in the atom.
Explanation:
The mass number of an atom of carbon represents the total number of protons and neutrons in the atom.
Mass number = number of protons + number of neutrons.
- The mass of an atom is concentrated in the nucleus of the atom.
- The particles in the nucleus are called nucleons are they are made up of the protons and neutrons.
- Protons are positively charged.
- Neutrons carry no charges.
- Together, they make mass of atom.
- The mass of electrons are negligible
