The correct answer is option (3).

The horizontal component of the force pushing the skier in forward direction is 36.75 N or 37 N.

In Physics, force is defined as the effect that changes the direction of motion of an object or brings a moving object to halt.

In other words, a force is a pull or push which is applied to any object. It is a vector quantity and is measured in Newton (N).

The weight of the skier = 75 Kg

To find the horizontal component of force we will use the following information.

Frictional force due to ice, F =   μN

Normal force N = mg = 75 x 9.8 = 735 N

Now let's calculate the Frictional force = 0.05 x 735 = 36.75 N

We know that the value of Coefficient of friction (μ) for ice is 0.05.

The atomic mass of an element is defined as the weighted average mass of that element’s
marishachu [46]

Answer:

False

Explanation:

Atomic mass (Also called Atomic Weight, although this denomination is incorrect, since the mass is property of the body and the weight depends on the gravity) Mass of an atom corresponding to a certain chemical element). The uma (u) is usually used as a unit of measure. Where u.m.a are acronyms that mean "unit of atomic mass". This unit is also usually called Dalton (Da) in honor of the English chemist John Dalton.

It is equivalent to one twelfth of the mass of the nucleus of the most abundant isotope of carbon, carbon-12. It corresponds roughly to the mass of a proton (or a hydrogen atom). It is abbreviated as "uma", although it can also be found by its English acronym "amu" (Atomic Mass Unit). However, the recommended symbol is simply "u".

<u> The atomic masses of the chemical elements are usually calculated with the weighted average of the masses of the different isotopes of each element taking into account the relative abundance of each of them</u>, which explains the non-correspondence between the atomic mass in umas, of an element, and the number of nucleons that harbors the nucleus of its most common isotope.
