3.57m/s²
Explanation:
Mass of swimmer = 70kg
Force on the swimmer = 250N
Unknown:
Acceleration = ?
Solution:
Force is a function mass and acceleration of a body.
Newton's second law of motion "The force acting on a body is equal to the product of mass and acceleration".
Force = mass x acceleration
The unknown here is acceleration; then we make it the subject of the formula:
Acceleration = =
Acceleration = 3.57m/s²

Explanation:
Given
-- radius of hydrogen atom
<em>See attachment</em>
Required
Determine the radius of magnesium atom (R)
From the attachment, the ratio of a hydrogen atom to a magnesium atom is:
Simplify
Represent the radius as ratio:
Substitute
Equate both ratios
Express as fraction
Cross Multiply
Hence, the radius of the magnesium atom is:
