a)
Answer:
Using Pythagorean Theorem.
[tex]F_{R} = \sqrt{Fn^{2} + Fe^{2} } \\\\ F_{R} = \sqrt{52.7^{2} + 91^{2} }\\\\ F_{R} = 105.16N[/tex]
b)
Answer:
[tex]tan^{-1} \frac{opp}{adj} \\ \\ tan^{-1} \frac{52.7}{91} \\ \\ = 30.08^{o}[/tex]
The resultant force of the two forces which are acting perpendicular to each other is 105.15 N and the direction is 59.91 ° from east.
What is force?Force is an external agent acting on a body to change it from the state of motion or rest. If two forces acting on a body and both are applied in the same direction, the resultant force will be the sum of two forces in magnitude.
If the two forces are in opposite directions, then the resultant force will be the substracted value of their magnitude. If one force is to the north and other is to the east, then they are perpendicular to each other.
Hence, to find the resultant force we can use the Pythagoras theorem for right angled triangle. The hypotenuse will be the resultant force.
Resultant force = √ (52.7² + 91² )
= 105. 15 N.
The direction of the force = Tan ⁻¹ (91 / 52.7 )
= 59.91 ° from east to north.
Hence, the resultant force is 105.15 N with a direction of 59.91 ° from east.

Which of the following best describes why longitudinal waves cannot travel in space?
Answer:
A longitudinal wave travels by displacement of material objects.
Air (for instance) particles transmit waves by their oscillation
Space has no material particles to transmit these waves.
write the energy conversion when a moving car braking to stop completely
Answer:
Friction braking is the most commonly used braking method in modern vehicles. It involves the conversion of kinetic energy to thermal energy by applying friction to the moving parts of a system. The friction force resists motion and in turn generates heat, eventually bringing the velocity to zero.

an elevator suspended by a vertical cable is moving downward but slowing down. the tension in the cable must be:
Answer:
F = M a is the vector equation involved
F = T - M g are the forces acting on the elevator (scalar equation)
T - M g = M a
T = M (a + g) remember this a scalar
If a is slowing down then it must have a positive acceleration upwards
Therefor the tension in the cable must be greater than zero
When the tension increases to M g, a has increased to zero
For a to be zero, no acceleration, T = M g
which state of matter has the greatest amount of kinetic energy?
Answer:
A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state.

Hii I need help ASAP with this physics question
A roller coaster has two vertical loops one after the other. The roller coaster has a speed of 7m/s at the top of the first loop with a height of 22.2m. It then proceeds around the second vertical loop with a height of 15.0m. What is the speed of the roller coaster at the top of the second vertical loop?
a.7m/s b.13.8m/s c.8.40m/s d.9.24m/s e.11.2m/s
Plz explain I can’t understand the question what I’m I supposed to use to calculate
Between the top of the first and the top of the second loop, the coaster has lost potential energy = mgh, where h = 22.2 - 15 = 7.2m
This energy would have converted to Kinetic. Write out an equation and the masses will cancel out. Does that hint help you to find the solution? If not, I will give you another hint.

a body dropped from a height reaches a velocity of 13m/s just before touching the ground. What is the initial height of the ball and the time of height
Hi there!
We can use the following (derived) equation to solve for the final velocity given height:
vf = √2gh
We can rearrange to solve for height:
vf² = 2gh
vf²/2g = h
Plug in the given values (g = 9.81 m/s²)
(13)²/2(9.81) = 8.614 m
We can calculate time using the equation:
vf = vi + at, where:
vi = initial velocity (since dropped from rest, = 0 m/s)
a = acceleration (in this instance, due to gravity)
Plug in values:
13 = at
13/a = t
13/9.81 = 1.325 sec
