Velocity of an object is its rate of change of the object's position per interval of time. Velocity is a vector quantity which means that it consists of a magnitude and a direction. Magnitude is represented by the speed and the direction is represented by the angle. To determine the velocity components, we use trigonometric functions to determine the angle of the components. For the north component we, use the sine function while, for the west component, we use the cosine function. We calculate as follows:
north velocity component = (16.8 m/s) (sin 54°) = 16.4 m/s
<span>west velocity component = (16.8 m/s) (cos 54°) = 3.49 m/s</span>
B.The water molecules in the black can had the largest increase in average kinetic energy.
<u>Explanation:</u>
Here, black painted can absorbs more heat than the other color painted cans.
Black color absorbs all the heat and didn't reflect anything back, so it absorbs the most heat.
White color reflects all the heat, so heat absorbed by the white can is least.
When the black can absorbs heat then the water molecules in the can gets its maximum amount of kinetic energy so that the water molecules in the can collide with each other and also along with the walls of the can here, and so the average kinetic energy increases.
Answer:
amplitude

sound travel and it amplifies
The visible color of light with the highest frequency is blue.
<h3>
What is visible light?</h3>
The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view.
<h3>Arrangement of visible color of light in increasing order of frequency</h3>
Visible color of light can be arranged in order of increasing frequency as follows;
- red
- orange
- yellow
- green
- blue
- indigo
- violet
Thus, the visible color of light with the highest frequency is blue.
