Answer:
D. 5.8 cm, 31 degrees South of the West axis
Explanation:
Here we have two vectors:
direction west
direction south
We note that the two vectors are perpendicular, so we can use the Pythagorean's theorem to find the magnitude of their resultant:
The direction can be found as follows:
And according to how we calculated the ratio inside the formula, this angle is measured as south of west.
I’d love to help, but I can barely understand what you put
Answer:
The answer is below
Explanation:
Given that the mass of the sculpture (m) = 6.2 kg,
Answer:
Lunar eclipse
Explanation:
Lunar eclipse occurs when Earth comes in between sun and Moon. The moon is either partially or fully blocked and the moon sighting appears to be black from earth since the light rays coming from sun are blocked by Earth. Lunar eclipse occurs only at full moon. The moon is aligned with the position of earth and sun so that they all form a straight line.
The only definite number we can tell you is that in order to lift
a 100kg box, you have to somehow provide a force of about
980 newtons (about 220 pounds) pointing upward. That's the
weight of the box, and you have to lift with at least that much force
just to get the box off the ground.
After that, the answer to your question is 'YES'. The time it takes
depends on how much force you have available, how far you want
to lift the box, and how fast.
Here are the Physics formulas you have to use:
-- The amount of "Work" you'll do is
(the amount of force you use) times (how far up you lift the box) .
-- The "Power" (amount of watts) you'll use is
(the amount of 'work' you do) divided by (the length of time it takes).
So ...
-- The higher you lift the box, the more 'work' your lift-machine does.
-- The faster the box is lifted, the more 'power' your lift-machine needs.
