In order to answer this, you can use this formula :
F = m.a
which means
a = F/m
a = 18N / 2kg
a = 9 N/kg or 9m/s2
hope this helps
Answer:
p = 49.95 cm
This is the distance from the student to the stepped, in order to be able to reach this distance they must sit in the first row
Explanation:
In medicine it is very common to express the potential visual corrections that is
P = 1 / f
where P is the power and f the focal length in meters
In this exercises give the power, let's find the focal length
f = 1 / p
f = 1/52
f = 0.01923 m = 1.923 cm
For geometrical optics calculations the most used equation is the constructor equation
1 / f = 1 / p + 1 / q
Where p and q are the distance to the object and the image, respectively
To be able to see an object clearly, its image must be on the retina,
q = 2.00 cm
find the distance to the object
1 / p = 1 / f - 1 / q
1 / p = 1 / 1,923 - 1/2.00
1 / p = 0.02002
p = 49.95 cm
This is the distance from the student to the stepped, in order to be able to reach this distance they must sit in the first row
I'm going to say that is it true because when electromagnetic waves occurs when a electric and magnetic field vibrates.
Hope this is correct and is what you are looking for!<span />
Had you included the picture, we would also know the height. Without that, we can't calculate the volume, and without the volume, we can't calculate the density.
