Answer: a. 198.6J b. - 198.6J
Explanation: Parameters given:
m = 15kg
g = 9.8m/s²
∅ = 12°
a. Work done by the force Fp on the cart if the ramp is 6.5m long.
Given the formula, Fp = Mgsin∅ = 15 x 9.8 x sin12° = 30.56N
Therefore Work done (Wp) = Fp x Ramp Length = 30.56 x 6.5 = 198.64Nm or 198.6J
b. The work done by the force mg on the cart.
Since the cart is being pushed upwards, it acts against gravity with its direction of motion. Taking into account the formula from the previous answer for Work Done (Wg) = Fmg x distance
= 15kg x -9.8m/s² x Sin12° x 6.5m
= - 198.6J

There are 5 carbon atoms present in the Chemical formula, .
<h3>What is a chemical formula?</h3>
A chemical formula is used to show the number and type of atoms present in a molecule, using the atomic symbols of the elements and numerical subscripts.
From the chemical formula;
We can deduce that we have the following elements and their corresponding number of atoms in one molecule of the compound;
Carbon = 1 atom
Hydrogen = 1 atom
Chlorine = 3 atoms
So, in 5 molecules of the compound;
Carbon = 1 x 5 = 5 atoms
Hydrogen = 1 x 5 = atoms
Chlorine = 3 x 5 atoms = 15 atoms
In conclusion, from the solution above, we can say that we have 5 atoms of carbon present in 5 molecules of .
