Surveyors frequently use trig functions. Suppose that you measure the angle from your position to the top of a mountain to be 2.50∘. (Figure 6) If the mountain is 1.00 km higher in elevation than your position, how far away is the mountain?
Answers
Answer:
22.9km
Explanation:
If the mountain is 1.00 km higher in elevation than your position and the angle measured from your position to the top of a mountain is 2.50∘.then you would have been 22.9 km far away from the mountain
What are trigonometric functions?A right-angled triangle's side ratios are the easiest way to express a function of an arc or angle, such as the sine, cosine, tangent, cotangent, secant, or cosecant. These functions are known as trigonometric functions.
As given in the problem you measure the angle from your position to the top of a mountain to be 2.50∘. If the mountain is 1.00 km higher in elevation than your position,
By using the tangent trigonometric function for the right triangle
tanθ = height /distance
tan 2.5° = 1000 m /distance
distance =1000 m /tan 2.5°
=22903 m
=22.9 km
Thus, the mountain is 22.9 km far away from your position

magnets' persistent magnetic fields.Things that create their own persistent magnetic fields are known as permanent magnets.They have a north and a south pole and are built of magnetized ferromagnetic elements, such as iron and nickel.
More than one solution to the question "what causes a magnetic field?"
may be true.Charged particles that are in motion produce all magnetic fields.Due to the continually moving electrons inside, even the magnet on your refrigerator is magnetic. A magnetic field is produced along the axis of a wire loop by a current flowing through it.Curling the fingers of the right hand in the direction of the current through the loop and pointing the thumb in the direction of the magnetic field will reveal the direction of the field inside the loop. The magnetic field strength of an electromagnet or solenoid, depends on the number (N) of coil turns, the strength of current flowing through the coil in amperes, and its length L. This gives us: H = (NI)/L where NI represents the ampere-turns value.Items made of iron, cobalt, nickel, and steel are drawn to magnets.Paperclips are magnetic because they are often constructed of galvanized steel wire. Any of the following techniques can create a magnetic field:I Any type of magnet, including round, horseshoe, and bar magnets, may be employed.(ii) A current-carrying wire generates a field all around it.(iii) A current-carrying loop or solenoid Electric charges in motion are what generate magnetism.The smallest building blocks of matter are called atoms.There are electrons in every atom, which are charged particles.The electrons that make up an atom's nucleus, or core, spin like tops. Ampere noted that whenever an electrical charge is moving, a magnetic field is created.Similar to how an electrical current flowing through a wire creates a magnetic field, the spinning and circling of an atom's nucleus accomplishes the same.The magnetic field's orientation is determined by the spin and orbit directions. There are only two ways to create a powerful magnetic field.In the first, a solenoid is used, whereas in the second, a solenoid with an iron core is used. Magnetic materials found in nature are connected to magnetic fields.Instead of static charges, a magnetic field can be produced by moving charges.F = QVB, where Q is the charge and V is the charge's velocity perpendicular to the field B, describes the force acting on moving charges in a magnetic field.To learn more about magnetic field refer

Magnetic energy is used by an electromagnet to pick up metallic objects
Explanation:
An electromagnet generates its own magnetic field in presence of electric current.
As an electric current is induced in an electromagnet , it magnetic dipole arrange themselves in order to behave as a magnet and hence generate magnetic field with a proper north and south. This leads to attraction of metallic object.
Hence, it can be said that Magnetic energy is used by an electromagnet to pick up metallic objects

Write your question here (Keep it simple and clear to get the best answer) a car accelerates uniformly from an initial velocity of 10m/s at 2m/s squre for 4s.What is the average velocity
Answers
Answer:
Average velocity = 18 m/s
Explanation:
Given the following data;
Initial velocity = 10m/s
Acceleration = 2m/s²
Time = 4 seconds
To find the average velocity, we would use the first equation of motion;
[tex] V = U + at[/tex]
Where;
V is the final velocity.
U is the initial velocity.
a is the acceleration.
t is the time measured in seconds.
Substituting into the equation, we have;
V = u + at
V = 10 + 2*4
V = 10 + 8
V = 18 m/s

A student is blowing against the mouthpiece of a 668mm flute (open at both ends) causing it to resonate. (The air inside and outside the flute is 24.5°C)
1) what is the speed of the sound in the flute?
2) what is the fundamental frequency of the note produced?
3) what is the wavelength of the sound wave?
Answers
Answer:
a) v = 345.5 m / s, b) f = 183.8 Hz, c) λ = 1,336 m
Explanation:
a) the speed of sound depends on the density of the medium and this depends on the temperature, therefore
v = [tex]v_o \ \sqrt{1+ \frac{T}{273} }[/tex]
where v₀ is the speed of sound at 0ºC v₀ = 331 m / s
v = 331 [tex]\sqrt{1 + \frac{24.5}{273} }[/tex]
v = 345.5 m / s
c) In the exercise they indicate that the flute is a tube with the two ends open, so that at each end there is a belly, the resonance is
λ / 2 = L
λ = 2L
λ = 2 0.668
λ = 1,336 m
b) let's apply the relationship between speed, wavelength and frequency
v = λ f
f = v /λ
f = 345.5 / 1.336
f = 183.8 Hz
Pedro is planning to model how changes in weather affect evaporation from lakes. For his first experiment, he wants to test how humidity affects the evaporation rate. He places one beaker with 300 mL of water in a dry area, and he places another beaker with 300 mL of water near a humidifier. Which of the following variables does Pedro need to control during his experiment?
Answers
The aim of the experimental model is to test the effect of humidity (changes in weather) on evaporation (rates) from lakes
The control variables in an experiment are the variables that the experimenter intends to keep constant always so as to limit their effect on the measurements of the relationship between the dependent and the independent variable
Therefore in order to have a proper measurement of the effect of humidity on evaporation rate, other variables such as temperature, and the volume of the water in the experiment investigations which affect evaporation rate by the provision of heat, (temperature) and their heat capacity, (the volume and therefore, mass of water) should be controlled

If you are in a car that stops suddenly, what does your body continue to do?
Answers
Answer:
If the passengers were not wearing their seat belts:, then the passengers in motion would continue in motion. Assuming a negligible amount of friction between the passengers and the seats, the passengers would likely be propelled from the car and be hurled into the air. Once they leave the car, the passengers becomes projectiles and continue in projectile-like motion.
If they were: Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts. Being strapped tightly to the car, the passengers share the same state of motion as the car. As the car accelerates, the passengers accelerate with it; as the car decelerates, the passengers decelerate with it; and as the car maintains a constant speed, the passengers maintain a constant speed as well.

What factors affect Kinetic Energy? a. Mass and Height b. Velocity and Time C. Mass and Velocity d. Mass and Time
What factors affect Potential Energy? a. Mass and Height b. Velocity and Time c. Mass and Velocity d. Mass and Time
Answers
Answer:
Q1: c
Q2: a
Explanation:
you can tell the factors by looking at the formulas for kinetic and potential energy
for question 1 look at the formula for kinetic energy
[tex]KE=\frac{1}{2} mv^{2}[/tex]
the variables needed in order to calculate an object's kinetic energy are mass and velocity.
hence, when mass and velocity changes, kinetic energy changes, showing that mass and velocity are the factors affecting kinetic energy
same thing for the second question
[tex]PE = mgh[/tex]
as g (acceleration due to gravity) is considered constant (10 [tex]m/s^{2}[/tex] ) it will not be considered as a factor
and thus, the factors affecting potential energy are mass and height
