Question:
Use your knowledge of waves in the graph shown to determine the frequency of wave C. What does it tell you about the speed of the wave?
Answers
"Frequency" means how often something happens. When you say how many times it happens every SECOND, you can call the number Hertz, or Hz.
In the graph, there are 10 vibrations in 10 seconds, 20 of them in 20 seconds, and 30 in 30 seconds. This should pretty much shout at you "THERE'S ONE VIBRATION EVERY SECOND !". When you realize that, you can say the frequency of the vibration is 1 Hz.
The graph tells us nothing about the speed of the waves. I suspect there's another picture to the question that you didn't include. If the other part shows the wavelength, then we could figure out the speed. But with just what you're showing us, we can't.

Explanation:
1. Determination of the mass of gasoline
Density of gasoline = 0.7 Kg/L
Volume of gasoline = 15 L
Mass of gasoline =?
The density of a substance is simply defined as the mass of the substance per unit volume of the substance. Mathematically, the density of a substance can be expressed as:
Density = mass / volume
With the above formula, we can obtain the mass of the gasoline as follow:
Density of gasoline = 0.7 Kg/L
Volume of gasoline = 15 L
Mass of gasoline =?
Density = mass / volume
0.7 = Mass of gasoline / 15
Cross multiply
Mass of gasoline = 0.7 × 15
Mass of gasoline = 10.5 Kg
2. Density has various units some are listed below:
I. Kilogram per litre (Kg/L)
II. Kilogram per cubic metre (Kg/m³)
III. Milligram per millilitre (mg/mL)
IV. Gram per millilitre (g/mL)
V. Gram per cubic centimetre (g/cm³)
Considering the options given in the question above, it is evident that second per gram (s/g) is not a unit of density because density is mass per unit volume.

One advantage that sexual reproduction has over asexual reproduction is the ability to produce genetic diversity. Why is genetic diversity an advantage?
Answers
Answer:
Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population

A horse pulls a carriage by applying 450 N of force. Find the traveled distance if the horse did 89 kJ of work.
Answers
Answer:
distance = 197.8 m
Explanation:
Use the formula for work as the force times the distance the force was acting on the object.
W = F * d
89000 J = 450 N * d
d = 89000/450 m
d = 197.8 m
Calculate the watts of power expended when a force 400 N travels 12 meters over 10 seconds.

explain why a solid steel ball sinks in water but a steel ships floats in water
Answers
Answer:
floating had to do with the pressure rather than the weight
Explanation:
the water pressure on the bottom of the boat is so hard and pushing that it causes it to float.. And the steel ball has alot of density. which is causing it to sink
Answer:
because of its displacement, a ship displaces water. when a steel ball does not.

The results suggested that the diameter of the nucleus of a gold
the diameter of the atom.
The diameter of a gold atom is 0.18 nm
Calculate the diameter of a gold nucleus in nm.
Answers
Answer:
The diameter of the gold nucleus is 3.0 × 10⁻⁵ nm
Explanation:
The given parameter of the gold atom are;
The diameter of the gold atom = 1/6,000 × The diameter of the atom
The diameter of a gold atom = 0.18 nm
The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 1/6,000 × 0.18 nm = 0.00003 nm
∴ The diameter of the gold nucleus, [tex]d_{Gold -nucleus}[/tex] = 0.00003 nm = 3.0 × 10⁻⁵ nm.
