Answer: The angular magnification M = 2.1
Explanation:
If the jeweler holds the diamond at the focal point of the magnifying glass, its image will be produced infinitely far away.
This gives an angular magnification of M = N/f
Since the diamond is held 5.68 cm from the magnifying glass,
Then, M = (N - 5.68)/f
Where N = 22.0 cm and f = 7.7 cm
M = (22 - 5.68)/7.7
M = 2.1
Answer:
F. The length of day would be longer
Explanation:
- Earths rotates on its axis from the eastward to the westward direction, earth takes about 24 hours to complete its rotation. If the rate of earth's rotation on its axis slows down then the days will be longer than usual.
- Thought the length of year would remain the same. Earth rotation is also impacted by the sun and moon's gravitational pull. The disappearance of the centrifugal force form the surface would cause climate changes and seasonal extremes.
Answer:
a).
b).
c).
Explanation:
The angular acceleration is constant so we can use the formulas of uniform motion with the model of angular acceleration
a).
so the total angle between t=0 and the time it stopped is
b).
=
c).
Answer:
Proper Inflation and Feel When inflating your ball, you can use either a hand pump or an air pump equipped with a gauge that gives readings in pounds per square inch, also called psi. Footballs used in the NFL are inflated to 13 psi, but a proper range can fall between 12.5 and 13.5 psi, according to Wilson Sporting Goods.
