Lots of factors play a role. Firstly if he is presbyopic he won't be able to read without specs at normal reading distances. Many years ago a chap by the name of Donders published a table which shows a linear relationship between age and ability to focus. The ready made reader market relies on his findings to suggest the power you need for reading at different ages. Secondly if he is far sighted (needing correction at distance to see clearly) it will also influence his ability to see close. For example +3.00D distance Rx at an age of 40 years will be very different than the same prescription at age 20 years due to his ability to accommodate. My suggestion is to have comprehensive eye exam to find out what you need at the specific working distance (computer or laptop or book reading all have different reading distances).
The distance of separation between the two masses is 0.927 m.
<h3>Gravitational force:</h3>
This is the force that exists between two masses in the universe.
To calculate the distance of separation of the masses, we use the formula below.
- F = GMm/r².............. Equation 1
Where:
- F = Gravitational force
- m = First mass
- M = Second mass
- G = Universal constant
- r = distance of seperation.
Make r the subject of the equation.
- r = √(GMm/F)................... Equation 2
From the question,
Given:
- F = 3.3×10⁻⁷ N
- m = 61 kg
- M = 75 kg
- G = 6.69×10⁻¹¹ Nm²/kg²
Substitute these values into equation 2
- r = √(61×75×6.69×10⁻¹¹)/(3.3×10⁻⁷)
- r = 0.927 m
Hence, The distance of separation between the two masses is 0.927 m

D the gray wolves in the forest.is the correct answer.
Answer:
Explanation:
We are given that
Initial velocity of baseball=u=-41m/s
Because final and initial velocity are in opposite direction
Final velocity of baseball=v=47m/s
Time=t=1.9 ms=
1 ms=
We have to find the acceleration .
We know that
Acceleration=
Using the formula
Acceleration=
Acceleration=
Answer:
I think it is but I don't know for sure
