Answer:
F = 8066.67 N
Explanation:
The extra force exerted on the bottom of the jug can be expressed as the pressure generated by the cork multiplied by the area of the bottom. We can also obtain the Pressure P by dividing the force F1 applied to the cork by it's area A1.
Thus;
F = PA2 = (F1/A1) x (A2)
F = (F1/(πd1²/4)) x (πd2²/4)
π/4 will cancel out to give;
F = F1(d2/d1)²
F = 150(16.5/2.25)
F = 8066.67 N
1 centigram is equal to 10 milligrams.
Divide 3.88 milligrams by 10 to convert into centigrams.
3.88 / 10 = .388
The answer is .388 centigrams.
Answer:
Vx = 35.31 [km/h]
Vy = 18.77 [km/h]
Explanation:
In order to solve this problem, we must decompose the velocity component by means of the angle of 28° using the cosine function of the angle.
In order to find the vertical component, we must use the sine function of the angle.
Answer:
Explanation:
The index of refraction is equal to the speed of light c in vacuum divided by its speed v in a substance, or . For our case we want to use , which for our values is equal to:
Which we will express with 3 significant figures (since a product or quotient must contain the same number of significant figures as the measurement with the <em>least</em> number of significant figures):
C) light waves travel faster than sound waves
