Answer:
B) 10 minutes
Explanation:
When the size of the problem is 100 then it takes 1 minute to solve
So, when the size of the problem is 1 then it takes the following minutes
For when the size of the problem is 1000 we have
So, it will take 10 minutes to solve the algorithm of size 1000
Answer:
The distance is 
Explanation:
From the question we are told that
The smallest shift is 
Generally a grid unit is 
of an arcsec
This implies that 0.2 grid unit is 
The maximum distance at which a star can be located and still have a measurable parallax is mathematically represented as
substituting values
Note 
So 
Work = force x distance. In units, Joules = Newtons x meters.
So: Work = 50 Newtons x 3 meters
Work = 150 joules. Answer D is correct
FYI - to ace physics, you should learn to identify these values using their fundamental units:
Force = Newtons = Kg·m/s²
Work = joules = kg·m²/s²
Power = watts = kg·m²/s³
In high school physics, If you learn to arrange equations so the units work out properly for the answer, you'll get most problems correct.
Answer:
Images formed by a convex mirror are always virtual
Explanation:
A virtual image is always created by a convex mirror, and it is always situated behind the mirror. The picture is vertical and situated at the focus point when the item is far away from the mirror. As the thing approaches the mirror, the image follows suit and increases until it reaches the same height as the object.
