Work = (force) x (distance
28.4 joules = (force) x (4 meters)
Divide each side by (4 meters) :
Force = (28.4 joules) / (4 meters)
Force = 7.1 Newtons
Answer:
f = - 0.143 m = - 14.3 cm
Explanation:
First, we will calculate the power of the combination of lenses:
P = P₁ + P₂
where,
P = Power of Combination = ?
P₁ = Power of first lens = - 5D
P₂ = Power of second lens = - 2D
Therefore,
P = - 5D - 2D
P = - 7D
Now, the focal length can be given as:

<u>f = - 0.143 m = - 14.3 cm</u>
Negative focal length indicates that combination will act as diverging lens.
From the choices provided, the better answer is ' T ', being the
one-letter acronym for the words "true", "truth", and "trust".
This choice is the preferred one, because the statement that
precedes it, dealing with relative motion, is a factually correct
statement.
Kinda but a football field is 100 yds. (91.4m), so not really because a Wide Receiver doesn't usually run down the entire field in one play. Also they have to pace themselves because they have to run more than one play in a whole game.
You just multiply these two numbers, it's 100J
