Answer:
C. Data is analyzed on a computer
Explanation:
Computers can analyze electrical signals, not radio signals. This means that the radio waves need to be converted to electrical signals to help the computer analyze the data.
g The ant has traveled 10 cm horizontally and 6 cm vertically from its starting point on a twig with a slope of 0.5. If this is the only information the ant has, what function best approximates the geometry of the twig at the point the ant is on? b) The ant can use its model of the environment to plan its movements. In particular, it wants its next step to take it no higher than 0.1 cm above its current location. How far can the ant travel horizontally and still accomplish this?
Answer:
a) a right triangle, b) x = 0.167 m
Explanation:
a) It is asked to find which geometry figure describes the movement of the ant.
Let's use trigonometry with the angles measured in radians
tan θ = y / x
tan θ = 6/10
θ = tan⁻¹ 0.6
θ = 0.54 rad
this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle
b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea
x = 0.1 / tan 0.54
x = 0.1668 m
x = 0.167 m

A meteor moving through space speeds up as it gets closer to Earth. What force causes the meteor's speed to increase the closer it gets to Earth?
PLS Help
Answer:
gravity
Explanation:
its hard to explain its one of the resons we do gravity assists for space probes and such the meteor will catch earths gravity and be pulled in by it if you look at sednas orbit as it gets closer to the sun it speeds up.
The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.
What is meant by gravity ?Gravity is defined as the force by which a planet attracts another body towards its center.
Here,
The meteor was moving through space and the speed of the meteor started increasing as it moves closer to the earth.
This is because of the gravitational force of earth that is being exerted on the meteor. Gravitational force of earth is defined as the force of attraction that the earth exerts on another body in its gravitational field and draws them towards the center of the earth.
As the meteor moves towards the earth's , it gets accelerated by the earth's gravitational field such that the speed of the meteor increases and thus it attains more kinetic energy. As a result, the meteor moves faster when it gets closer to earth. This is because of the force of gravity of the earth.
Hence,
The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.

Determine whether the interference is constructive or destructive at each location indicated.
A.constructive or destructive
B. constructive or destructive
C. constructive or destructive
D. constructive or destructive
Answer:
A. Constructive
B. Destructive
C. Destructive
D. Constructive
Explanation:
Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves
Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves
Therefore;
At point A, the peak of each wave partially coincides resulting in constructive interference
At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference
At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference
At point D, the trough of each wave partially coincides resulting in constructive interference.

the average speed,
her average velocity .
in her change in velocity for the whole journey!
The average speed of the girl is 1.2 m/s.
Average velocity is defined as the trade in position or displacement (∆x) divided by the time durations (∆t) wherein the displacement takes place. The common velocity can be effective or negative depending upon the sign of the displacement. The SI unit of average velocity is meters per second (m/s or ms-1).
Given;
Total distance = 40 + 20 = 60 M
Displacement = 40 - 20 = 20 m south
total time = 40 + 10 = 50 seconds
Average speed = total distance / total time
= 60/50
= 1.2 m/s
average velocity = total displacement / total time
= 20 / 50
= 0.4 m/s due south.
Average velocity is calculated by means of dividing your displacement (a vector pointing out of your initial role in your final position) through the entire time; the average pace is calculated by way of dividing the overall distance you traveled by means of the total time.

See attachment for wave pattern
Required
What is the wavelength
To do this, we simply calculate the distance between successive waves (see attachment 2 for point A and B)
Using the ruler, points A and B are at:
[tex]A = 0.6cm[/tex]
[tex]B = 2.3cm[/tex]
So, the wavelength is:
[tex]\lambda = B - A[/tex]
[tex]\lambda = 2.3cm - 0.6cm[/tex]
[tex]\lambda = 1.7cm[/tex]
If approximated, the wavelength is:
[tex]\lambda \approx 2cm[/tex]
A rocket pushes exhaust 10, 000 N. Without any other forces acting on the rocket, how much force does the rocket go forward? *
Answer:
10,000 N
Explanation:
Given that a rocket pushes exhaust 10, 000 N. Without any other forces acting on the rocket, how much force does the rocket go forward?
Solution
Since there is no any other additional forces, according to Newton's 3rd law of motion which state that:
In every action there will be equal and opposite reaction.
The action expelled by the rocket through its exhaust system is of 10000N.
The reactive force will be equal and opposite which will be same -10,000 N
Therefore, the rocket will go forward with a force of magnitude 10,000 N
A cruise ship travels across a river at 25 meters per minute. If the river is 6200 meters wide, how long
does it take the ship to reach the other side.
Answer:
248 minutes
Explanation:
6200/25=248
This means there is 248 25s in 6200
which means it will take 248 minutes to travel through the river
Also here's a neat trick:
The units for speed is meters/minute
The units for distance is meters
Dividing distance by speed will cancel out the meters and leave only the speed.
The local newspaper has published the passage below. Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn. Which statement in the news passage above is inaccurate
Answer:
The statement as aurora australis known as northern lights is incorrect. As the designation of aurora australis is for the southern lights i.e. which occur in the southern hemisphere.
Explanation:
Aurora or natural lights is a phenomenon that occurs at the poles of the Earth due to interaction between the Earth's magnetic field and cosmic rays. This interaction results in the beautiful display of colors on both poles. These are named, aurora borealis or aurora australis depending on their geographical location. If they occur on the northern pole they are termed as aurora borealis while those occurring on the southern pole are named aurora australis.
Answer:
C. The aurora australis is known as the northern lights.

The velocity of a car increases from +4.0 m/s to +16.0 m/s
in a time period of 4.0 s. What was the average
acceleration?
Answer:
Explanation:
Although we do have an equation for this in terms of one-dimensional motion, it's easy enough just to use the mathematical definition of acceleration:
[tex]a=\frac{v_f-v_0}{t}[/tex] which says, in words, the acceleration of an object is equal to the objects final velocity minus its initial velocity, divided by the change in time. Since everything is given in m and s, our answer will be in m/s/s:
[tex]a=\frac{16.0-4.0}{4.0}[/tex] and
[tex]a=\frac{12.0}{4.0}[/tex] so
a = 3.0 m/s/s

2. Why is alcohol thermometer not suitable to measure high temperature?
Answer:
Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury freezes at -38 degrees C.
Explanation:
It is less durable because alcohol evaporates faster than mercury. It cannot measure high temperature because of a low boiling point. It wets the walls of the thermometer, which can adversely impact the accuracy of readings
