The news media, such as newspapers and television stations, carry current events worldwide. Explain how the way news travels is similar to the way a wave travels.
Answer:
A simile can be established with the news, where the fact that occurs is the matter of has some type of oscillation or disturbance, which occurs somewhere and is there, the news is the wave that carries the information of this fact the energy of the same to all points, therefore it is equivalent to a traveling wave.
Explanation:
Traveling waves are disturbances of the medium that are transmitted with a constant speed, where matter is subjected to oscillations around its equilibrium point, transporting only energy.
A simile can be established with the news, where the fact that occurs is the matter of has some type of oscillation or disturbance, which occurs somewhere and is there, the news is the wave that carries the information of this fact the energy of the same to all points, therefore it is equivalent to a traveling wave.
The news is the wave that carries the information of this fact and the energy of the same to all points, making it equivalent to a traveling wave.
What is a wave?A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify them.
Transverse and longitudinal are the two main forms.
The wave can be compared in the form of news as
The news is the wave that carries the information of this fact and the energy of the same to all points, making it equivalent to traveling. wave.
Traveling waves are medium disturbances that are conveyed at a constant pace, where matter oscillates around its equilibrium point, transferring only energy.

If a skateboarder is moving at 4 meters per second then changes its velocity to 10
meters per second over the course of 10 seconds what is the skateboards acceleration?
Answer:
i was doing this is it actually 0.6
Explanation:
;D
The acceleration of the skateboard from its initial velocity to the final velocity over the given time is 0.6m/s².
What is Motion?Motion is simply the change in position of an object over time.
From the First Equation of Motion;
v = u + at
Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.
Given the data in the question;
Initial velocity u = 4m/sFinal velocity v = 10m/sTime elapsed t = 10sAcceleration of the skateboard a = ?To determine the acceleration of the skateboard, we substitute our given values into the expression above.
v = u + at
10m/s = 4m/s + ( a × 10s)
( a × 10s) = 10m/s - 4m/s
a × 10s = 6m/s
a = 6m/s ÷ 10s
a = 0.6m/s²
Therefore, the acceleration of the skateboard from its initial velocity to the final velocity over the given time is 0.6m/s².

13. A chemical costs $5.25 per pound. What would be the cost of 10.0 kg of the chemical?
Answer:
$ 115.76
Explanation:
From the question given above:
1 pound of a chemical cost $ 5.25
To obtain the cost of 10 Kg of the compound, we must convert 10Kg to pound. This can be obtained as follow:
1 Kg = 2.205 pound
Therefore,
10 Kg = 10 Kg / 1 Kg × 2.205 pound
10 Kg = 22.05 pound
Therefore, 10 Kg is equivalent to 22.05 pounds
Finally, we shall determine the cost of 22.05 pounds as follow:
1 pound of a chemical cost $ 5.25.
Therefore, 22.05 pounds of the chemical will cost =
22.05 pound / 1 pound × $5.25
= $ 115.76
Therefore, 10 Kg (i.e 22.05 pound) of the chemical cost $ 115.76
A car traveling at 26.8m/s hits the brakes to slow down before turning into a neighborhood. Determine how fast it is going after slowing down at a rate of -8.2m/s2 for 14.3seconds.
Answer:
The speed of the car after the break was applied is 90.46 m/s
Explanation:
Given;
initial velocity of the car, u = 26.8 m/s
accelertation of the car, a = -8.2 m/s²
time of motion, t = 14.3 s
final velocity, v = ?
Apply the following kinematic equation;
v = u + at
v = 26.8 + (-8.2 x 14.3)
v = 26.8 - 117.26
v = -90.46 m/s
magnitude of the final velocity = 90.46 m/s
Therefore, the speed of the car after the break was applied is 90.46 m/s

B) What is her average velocity over the entire trip?
Answer:
A.) 3.975 m/s
B.) 0.925 m/s
Explanation:
Given that a person walks first at a constant speed of 4.90 m/s along a straight line from point A to point B and then back along the line from B to A at a constant speed of 3.05 m/s.
A) What is her average speed over the entire trip?
The average speed = (4.90 + 3.05)/2
Average speed = 7.95/2
Average speed = 3.975 m/s
B) What is her average velocity over the entire trip?
Since velocity is a vector quantity, that is, we consider both the magnitude and direction
Average velocity = ( 4.90 - 3.05)/2
Average velocity = 1.85/2
Average velocity = 0.925 m/s

Ohnny walks 900 meters to the store to buy a candy bar. He then walks back home. His total trip took him 30 minutes. What was his average speed? 0 points 1 m/s 10 m/s 30 m/s 27,000 m/s
Answer:
Average speed = 1 m/s
Explanation:
Given that,
Ohnny walks 900 meters to the store to buy a candy bar. He then walks back home. It would mean that the total distance covered by him is 900 m + 900 m = 1800 m
His total trip took him 30 minutes or 1800 seconds
We need to find the average speed. It is equal to the total distance divided by the total time taken. So,
[tex]v=\dfrac{1800\ m}{1800\ s}\\\\v=1\ m/s[/tex]
So, his average speed is 1 m/s.
