Answer:
5.63 microgram (μg)
Explanation:
Here mass is given in miligram
Some of the prefixes of the SI units are
1 gram = 10⁻³ kilogram
1 milligram = 10⁻⁶ kilogram
1 microgram = 10⁻⁹ kilogram
1 nanogram = 10⁻¹² kilogram
1 microgram = 10⁻³ miligram
The number is 0.783
Here, the only solution where the number of significant figures is three is microgram. If any other prefix is chosen then the significant figures will increase.
So, 0.00563 miligram = 5.63 microgram
Because we should convert units within the metric system
Answer:
ball with a mass of 1 kg is moving in a straight line at the same speed as a ball with a mass of 10 kg
Explanation:
The output of the machine is
(output work) = (output force) x (distance)
450 N-m = (output force) x (3 meters)
Divide each side
by 3 meters: Output force = (450 N-m) / (3 m)
= 150 newtons .
With all the information given about the output work, we don't need
to know anything about the input work, or even the fact that we're
dealing with a machine.
It's comforting, though, to look back and notice that the output work
(450 N-m) is not more than the input work (500 N-m). So everything
is nice and hunky-dory.
___________________________________
Well, my goodness !
I didn't even need to go through all of that.
Given:
-- The input force to the machine is 50 newtons.
-- The mechanical advantage of the machine is 3 .
That right there tells us that
-- The output force of the machine is 150 newtons.
We don't need any of the other given information.
