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?
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

The answer is -7m, but I don’t know how that’s the answer. Can anyone explain?
Explanation:
At first it is in 14m position but position doesn't matter in displacement, similar case for time taken.
So at first it travels 6m in positive direction.
So displacement= 6m
Then it travels 13 in opposite or negative direction.
So displacement = 6 -13 m = -7 m

We have that the instantaneous velocity of the shuttlecock when it hits the ground is

From the question we are told
Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the
shuttlecock when it hits the ground? Show your work below.
Generally the equation for acceleration is mathematically given as
[tex]a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2[/tex]
Where
acceleration is still -9.81 m/s2,
Hence,
[tex]V^2-U^2=2(-9.81)*-H[/tex]
Therefore

an object is moving forward with a constant velocity. which statement about this object must be true?
Answer:
• Its acceleration is zero
Explanation:
from definition of acceleration:
[tex]{ \rm{acceleration = \frac{change \: in \: velocity}{time} }} \\ \\ { \rm{acceleration = \frac{ \delta \: (velocity)}{time} }}[/tex]
• since velocity is constant, change in velocity is zero

a. Define displacement
b. Use the definition of displacement to explain how it is possible for an athlete to run round a track yet have no displacement
Answer:
definition: the moving of something from its place or position.
Explanation:
though moving around a track they will always end in the same place therefore there is no displacement from the beginning position
There is no displacement from the starting position because they will always wind up in the same place as they started.
What is displacement?Displacement is defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into account both the direction of the motion and the magnitude of the changing position. Displacement may be zero, positive, or negative.
The initial and final positions are needed in order to calculate displacement because displacement does not provide comprehensive information on the full path length.
The displacement is the shortest distance from the starting point to the finish point, the athlete starts from the start line and reaches the finish line after running through the whole track, but the starting point and the finishing point are the same, so the displacement is zero.
Therefore, the displacement of the athlete running through the track is zero for a complete race.

The moon is being pulled to the earth by gravity, so the net force makes a circular pattern.
Explanation:
The force of gravity is a force that pulls objects toward the centre of the earth. The acceleration due to gravity of the moon is about 1.6 metre per second square which is comparatively smaller than the earth's 10metre per second. Therefore, the moon isn't completely pulled to the centre of the earth, but orbits around the earth
a typical 100-watt light bulb consumes 100 j of energy per second. if a light bulb converts all of this energy to 400 nm light, how many photons are produced each second?
Answer:
Let y equal lambda the wavelength of the light
e (photon) = h f = h c / y
e = 6.63E-34 * 3.0E8 / 400E-9
e = 6.63 * 3 / 400 * 10^-17
e = 4.97E-19
