Answer:
C - 11.76 N (Newtons)
Explanation:
2 steps are needed,
First find the Force being applied by the box on the surface.
F = M(a) [Force equals: mass X Acceleration (of gravity)]
You get 39.2 N of Force.
Plug in the remaining values into the equation for Frictional Force
F(f) = μ(F) [Coefficient of Friction X Force applied by the Box]
So
F(f) = 0.3(39.2) = 11.76 N (of Frictional Force)
Answer:
Compare brands first, but purchase the one that has lots of commercial advertisements, Compare ingredients and purchase the brand that is safe to use with soft contact lenses, Compare prices and purchase the most inexpensive brand.
Explanation:
Storm weather likely happens in the town when the air masses meet because of difference of temperature and humidity of both air masses.
<h3>What weather happens when air masses meet?</h3>
When air masses move by wind, they carry different weather conditions from the weather conditions of other region. This difference in weather conditions can create a severe storm.
So we can conclude that Storm weather likely happens in the town when the air masses meet because of difference of temperature and humidity of both air masses.
