Answer:
The incorrect part of the chart is;
Line 1
Chemical 
Reaction Nuclear Reaction
Line 1 Happens in the nucleus of atoms Happens between atoms
Explanation:
The given chart can be presented as follows;
Chemical Reaction Nuclear Reaction
1. Happens in the nucleus of atoms Happens Between atoms
2. Forms new compounds Forms new atoms
3. Involves small amounts of energy Involves large amounts of energy
From the above chart, line 1 is incorrect because a chemical reaction happens between the valence electrons of the reacting atoms while a nuclear reaction is the reaction that takes place between the nucleus of two or more atoms or the nucleus of an atom and a subatomic particle to produce one or more than new nuclide of a new atom with a change in the mass of the nucleus being represented by the large amount of energy in the reaction. Therefore, a nuclear reaction takes place in the nucleus of an atom, forms new atoms and involves large amounts of energy
The correct arrangement is presented as follows;
Chemical Reaction Nuclear Reaction
1. Happens Between atoms Happens in the nucleus of atoms
A. The Dawes limit tells
us that the resolving power is equal to 11.6 / d, where d is the diameter of
the eye’s pupil in units of centimeters. The eye's pupil can dialate to approximately
7 mm, or 0.7 cm. So 11.6 / .7 = 16.5 arc seconds, or about a quarter arc
minute ~ 17 arc seconds<span>
Although, the standard answer for what people can really see
is about 1 arc minute.

B. It is considered as linear, so given a 10 meter telescope
(10,000 mm): </span>
10000 / 7 = 1428 times
better for the 10 meter scope ~ 1400 times better (in 2 significant figures)

scope. Therefore we would expect </span></span>

we typically can get from a 7 cm scope.
Answer:
Explanation:
Work is given by the equation 
where 
is force and 
is displacement.
Displacement is defined as change in position. In this case, the box moves from 5m to 20m. Its displacement is 
.
The force acting on the box is the force of gravity, given as 
.
Therefore, the total work done is:
(two significant figures).
4 to 1
Explanation If you look at it as a fraction 160/40 and you reduce it down as far as you can you get 4/1
