I experienced these the past few days...
but hoped I helped ^_^
Answer:
4. meter rod
Explanation:
The length of an object is dimension that expresses how long the object is. It is measured in meters as the SI unit.
From the given question, to determine the length of a given table, the appropriate instrument that should be used is a meter rod. This would make it possible to measure in meters and know the exact dimension of the object with respect to how long it is.
A meter rod has a length of 1 m (100 cm), and can be easily used for the purpose.
Answer:
Only 9% weaker
Explanation:
Because this is where most stuff that people do in space takes place. So, um, here we're at a radius of the earth plus 300 kilometers. You may already be seeing why this isn't going to have much effect if this were except the 6.68 times, 10 to the sixth meters. And so the value of Gout here. You know, Newton's gravitational constant times, the mass of the Earth divided by R squared for the location we're looking at. And so this works out to be 8.924 meters per second squared, which is certainly less than it is at the surface of the earth. However, this is only 9% less than acceleration for gravity at the surface. So the decrease in the gravity gravitational acceleration of nine percent not really going toe produces a sensation of weightlessness.
