The distance of the object from the lens is 3.12 cm.
<h3>What is magnification?</h3>
Magnification is the process of of enlarging an apparent size of an object.
<h3>Object distance</h3>
The object distance is calculated using the following lens formula;
where;
- M is the magnification
- V is the image distance
- U is object distance
Thus, the distance of the object from the lens is 3.12 cm.

The formula to use is the one that connects the acceleration,
the distance fallen, and the time spent falling:
Distance = 1/2 a T² .
You said 2.1 meters in 0.6 second .
2.1 m = 1/2 a (0.6 sec)²
Multiply each side by 2 : 4.2 m = a (0.6 sec)²
Divide each side by (0.6 sec)² = (4.2/0.36) m/s² = a
a = (11 and 2/3) m/s²
(about 19% more than Earth's gravity)
NONE of those choices defines the law of conservation of energy,
and none even describes it. It's as if these choices belong to
a whole different question.
In fact, none of the choices is even a true statement by itself !
A statement that defines the law of conservation of energy
would have to say something like this:
The total amount of energy in any closed system is constant.
The total amount of energy after any event or process is the
same as the total amount was before it.
Answer:
see below
Explanation:
let one direction be negative and the other direction be positive
so
right = positive
left = negative
up = positive
down = negative
thus
d) -80 + 100 = 20 N
e) 35 - 55 = -20 N
