Answer:
Applied pressure is 1.08 10⁵ Pa
Explanation:
This exercise is a direct application of Boyle's law, which is the application of the state equation for the case of constant temperature.
PV = nR T
If T is constant, we write the expression for any two points
Po Vo = p1V1
From the statement the initial pressure is the atmospheric pressure 1.01 10⁵ Pa, so we clear and calculate
1 Pa = 1 N / m2
P1 = Po Vo / V1
P1 = 1.01 10⁵ 20/18.7
P1 = 1.08 10⁵ Pa
It is False in applying the pythagorean theorem to vector addition, the resultant vector is given by the perpendicular vector
<h3>What is Pythagoras theorem ?</h3>
A useful technique for figuring out the outcome of adding two (and only two) vectors that form a right angle to one another is the Pythagorean theorem. The technique cannot be used to combine more than two vectors or to combine vectors that are not at a 90-degree angle.
- The Pythagorean Theorem demonstrates how the side lengths of a right triangle can be calculated from the sum of the areas of three intersecting squares. This theorem is a very helpful tool that serves as the foundation for more intricate trigonometry ideas like the Pythagorean theorem's opposite.

Answer:
This process is termed galvanisation
a. The force applied would be equal to the frictional
force.
F = us Fn
where, F = applied force = 35 N, us = coeff of static
friction, Fn = normal force = weight
35 N = us * (6 kg * 9.81 m/s^2)
us = 0.595
b. The force applied would now be the sum of the
frictional force and force due to acceleration
F = uk Fn + m a
where, uk = coeff of kinetic friction
35 N = uk * (6 kg * 9.81 m/s^2) + (6kg * 0.60 m/s^2)
uk = 0.533
