The resultant of the four forces on the balloon is 1,212.35 N at 62⁰.
The given parameters;
Force applied to the north = 5120 NForce applied to the west = 1520 NForce applied to the east = 950 NForce applied to the south = 4050 NThe resultant vertical force is calculated as follows;
[tex]F_y = 5120 \ N - 4050 \ N\\\\F_y = 1,070 \ N[/tex]
The resultant horizontal force is calculated as follows;
[tex]F_x = 1520 \ N - \ 950 \ N\\\\F_x = 570 \ N[/tex]
The resultant of the four forces is calculated as follows;
[tex]F = \sqrt{F_y^2 + F_x^2} \\\\F = \sqrt{(1,070)^2 + (570)^2} \\\\F = 1,212.35 \ N[/tex]
The direction of the force is calculated as follows;
[tex]\theta = tan^{-1} (\frac{1070}{570} )\\\\\theta = 62^0[/tex]
Thus, the resultant of the four forces on the balloon is 1,212.35 N at 62⁰.

The weight of a luggage is 69.3 N on the moon. Find its weight on the Earth.
Answer:
Explanation:
weight on moon = 1/6* weight on earth
69.3=1/6*weight on earth
weight on earth = 69.3*6
weight on earth = 415.8 N
These 2 processes cause watersheds to change.
Answer:
Change is an integral component of the watershed. The wide variations in river and stream flow regularly change shorelines, stream channels and stream corridors. Upland areas of watersheds also undergo changes due to ecological succession, disease, competition, human activity and other factors.

Which statement compares the strengths of electric forces between particles of matter?
Please don't just guess for points, if your answer is wrong i'll report it.
A. Hydrogen bonds are stronger than ionic bonds but weaker than Van der Waals forces.
B. Metallic bonds are stronger than hydrogen bonds but weaker than ionic bonds.
C. Hydrogen bonds are weaker than Van der Waals forces but stronger than metallic bonds.
D. Metallic bonds are weaker than hydrogen but are stronger than ionic bonds.
B. Metallic bonds are stronger than hydrogen bonds but weaker than ionic bonds.
The statement is discussing the relative strengths of different types of electric forces that can exist between particles of matter.
Metallic bonds are formed by the sharing of electrons between atoms in a metal, and are considered relatively strong. Hydrogen bonds are formed between molecules that contain hydrogen and are relatively weak compared to metallic bonds.
Ionic bonds are formed between positively and negatively charged ions and are generally considered to be the strongest of these three types of bonds. Thus, the statement concludes that metallic bonds are stronger than hydrogen bonds but weaker than ionic bonds in terms of their relative strengths.

A. Mold grows on bread.
B. Bacteria make yogurt from milk.
C. Yeast produces air pockets in bread.
D. Baking soda produces bubbles when vinegar is poured on it.
Answer:
D. Baking soda produces bubbles when vinegar is poured on it.
Explanation:
Acetic acid = C₂H₄O₂
Baking soda = NaHCO₃
C₂H₄O₂ + NaHCO₃ → NaC₂H₃O₂ + H₂O + CO₂
When baking soda is added to vinegar, a chemical reaction will take place producing a huge amount of carbon-dioxide in the form of bubbles in the foaming mixture.

Heat flows into a gas in a piston and work is performed on the gas by its surroundings. The amount of work done is equal to the heat added. In this situation,
Answer:
The Internal energy of the gas did not change
Explanation:
In this situation the Internal energy of the gas did not change and this is because according the the first law of thermodynamics
Δ U = Q - W ------ ( 1 )
Δ U = change in internal energy
Q = heat added
W = work done
since Q = W. the value of ΔU will be = zero i.e. No change

Explanation:
formula: frequency = velocity/wavelength = [tex]\frac{3.0x10^{8} }{3.0x10^{2}}[/tex]i'm not sure because the teacher probably wrote the question wrong.Assume you have a person with a mass of 65 kg riding a skateboard down a ramp. While they are
still 4.8 m high, they are traveling at a speed of 8.0 m/s.
a) Calculate the Eg. [write here)
b) Calculate theEk [write here]
c) Calculate the Etotal. [write here]
d) If the ramp had a total height of 8.0 m, what would be their Eg, Ek, and Etotal at that height?
Answer:
a) Eg = 3,060.72 j
b) Ek = 2,080 j
c) Etotal = 5,140.72 j
d) Eg = 5,140.2 j
Ek = 0 j
Etotal = 5,140.2 j
Explanation:
The given parameters of the person riding the skateboard are;
The mass of the person, m = 65 kg
The height of the person (above ground level), h = 4.8 m
The speed at which the person is traveling, v = 8.0 m/s
a) The gravitational potential energy, Eg = m·g·h
Where;
m = The mass of the object at the given height = 65 kg
g = The acceleration due to gravity, g ≈ 9.81 m/s²
h = The height by which the object is elevated = 4.8 m
∴ Eg = 65 kg × 9.81 m/s² × 4.8 m = 3,060.72 joules
The gravitational potential energy, Eg = 3,060.72 J
b) The kinetic energy, Ek, is given as follows;
Ek = 1/2·m·v²
Where;
v = The velocity of the object = 8.0 m/s
∴ Ek = 1/2 × 65 kg × (8.0 m/s)² = 2,080 joules
The kinetic energy, Ek = 2,080 J
c) The total mechanical energy, Etotal = Eg + Ek
∴ Etotal = 3,060.72 j + 2,080 j = 5,140.72 J
The kinetic energy, Ek = 5,140.72 J
d) If the ramp had a total height of 8.0 m, we have;
At the 8.0 m height
Etotal = Eg(max), Ek = 0 j
With the given values, we get;
Eg(max) = 65 kg × 9.81 m/s² × 8 m = 5,101.2 joules = Etotal
Eg(max) = 5,101.2 j
Etotal = 5,101.2 j
Ek = 0 j
However, using only the values in the question with the assumption that all things being equal, we have;
Etotal = Constant = 5,140.72 j
Eg a the max height, 8.0 m = Eg(max) = Etotal = 5,140.2 j
Ek = 0 j
