The mass of the man is 86 kg. What is the force of friction that slowed him down? Use the equation for Newton’s second law, F = ma.
Answer:
Mass = 86 kg acceleration due to gravity = 10m/sExplanation:
So force =m*a
Mass = 86 kg acceleration due to gravity = 10m/s
Two waves are in phase if they are of the same ___________.
Answer:
frequency.
Explanation:
Two sound waves of the same frequency that are perfectly aligned have a phase difference of 0 and are said to be “in phase.” Two waves that are in phase add to produce a sound wave with an amplitude equal to the sum of the amplitudes of the two waves.
Explain what wave frequency is...
Explanation:
Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
Wave frequency is the number of waves that pass a fixed point in a given amount of time.
With energy, changes in the physical world are possible. These can be a change in speed, a change in direction, a change from cold to hot, and many other kinds of changes.
Question 4 options:
True
False
According to the Law of Conservation of Energy, the energy in a closed system is constant
The correct option for changes in the physical world are possible with energy, is the option;
True
Reason:
According to the Law of Conservation of Energy, energy cannot be created nor destroyed, but can be changed from one form to another
Therefore;
The changes in speed which is the change in kinetic energy is possible
Change in direction which is a change in velocity vector is change in kinetic energy is possible
Change from cold to hot by the addition of heat energy and other forms of energy
Therefore, the correct option is; True changes in the physical world are possible

Write a paragraph of five sentences or more explaining how the radio uses the behavior and characteristics of the radio wave to function.
Answer:
Radio waves have the longest wavelengths in the electromagnetic spectrum.You can tune a radio to a specific wavelength—or frequency—and listen to your favorite music. The radio "receives" these electromagnetic radio waves and converts them to mechanical vibrations in the speaker to create the sound waves you can hear.

I need with this. Answer as fast as you can
Answer:
Its the third answer!!!
Explanation:
Answer:
measure the time it takes for the dog to run a certain distance
Explanation:
Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
Although two identical objects may have the same mass and the same weight (meaning that the force of gravity is the same for both), they may not fall to Earth at the same rate. This is because of air resistance. Any object that is falling has friction, or resistance, from the air. The larger the object, the more resistance it has as it falls.
Get two identical pieces of paper. Crumple one up into a ball, but leave the other one a flat sheet. Drop both pieces of paper off a high place at the same time. What happens? Which falls faster? Record your observations and make a conclusion, using the terms “mass,” “weight,” “force,” “resistance,” and “gravity.”
MUST BE AT LEAST 4 sentences and include the terms weight, force, resistance, and gravity.
Answer:
the paper ball falls faster and the unfolded paper falls at a slower rate
Explanation:
this is because gravity is pulling both objects down to the ground and hence they are falling. Both objects have the same mass and weight but the resultant force of the paper ball is smaller than that of the unfolded paper. The unfolded paper has a larger surface area and so a larger force is acted upon it, meaning there is more air resistance. This shows that the paper ball falls faster than the unfolded paper.
The air resistance acting on the crumpled ball will be less and hence it will fall faster.
What is Air resistance?
Air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. The larger the object, the more resistance it has as it falls.
Mathematically, we can write it as -
F = [tex]\frac{1}{2} C_{D}[/tex] × ρv²A
Given are two identical pieces of paper such that one is crumpled up into a ball and the other one is left as flat sheet.
Now, as you throw both, the crumpled up ball and the flat sheet, the crumpled up ball will fall faster. The main reason behind this is that the total surface area of the crumpled ball in contact with the air is less than compared to that of the flat sheet. Air resistance on the crumpled ball with surface are in contact [say A(c)] can be written as -
F[1] = [tex]\frac{1}{2} C_{D}[/tex] × ρv²A(c)
And that on the flat sheet with area of contact with the air [say A(f)] can be written as -
F[2] = [tex]\frac{1}{2} C_{D}[/tex] × ρv²A(f)
Now as A(f) > A(c), therefore F[2] > F[1]
Therefore, the air resistance acting on the crumpled ball will be less and hence it will fall faster.

Debby and Ben took different routes to travel from Point A to Point E. Debby took the route along A, B, C, D, and E. Ben took the route along A, G, F, and E. Debby and Ben both took 4 hours to complete their walk. Their routes are shown. (3 points)
Which statement is true about Debby and Ben's average speed?
Ben and Debby's average speed was the same.
Debby's average speed was twice Ben's average speed.
Ben's average speed was twice Debby's average speed.
Debby's average speed was three times Ben's average speed.
Answer:
Ben's average speed was twice Debby's average speed.
Explanation:
Ben covered a total distance of 16 miles (10+4+2) and Debby covered 8 miles (3+2+2+1) which is half of what Ben covered. As they both reached the place in the same amount of time it tells us Ben was faster.
Calculate the speed of the object from 5 seconds to 10 seconds. Show your work and don't forget to include the units. (HINT for distance, make sure you are telling me the total distance traveled from 5 seconds to 10 seconds... no it is not 5 meters)

aᴀ, aʙ, aᴄ = ?
Solution
Based on the question, we know that the mass of road A, road B and road C are same. And, the formula of acceleration is
so, we can calculate the acceleration of road A, road B and road C.
• for road A
aᴀ = 7,7419 m/s²

If a steel nail is wrapped 8 times with an insulated copper wire and each end of is attached to a 1.5 V battery, we find that it will lift the weight of 2 large paper clips. We hypothesized that for each 8 coils, you will be able to pick up one additional paper clip. When we ran the experiment, we observed and recorded that when we added 8 more wraps around the nail (16 coils) we could lift 4 paper clips and when we added 8 more wraps (24 coils) we could lift 6 paper clips. Choose the correct conclusion to the experiment.
1. We redesign the test and hope for better results.
2. We concluded that every time we add 8 wraps to the nail the total number of paper clips lifted doubled.
3. We concluded that our original test flawed. Because of the results, 8 coils should be able to pick up 2 paper clips. We will check our original test with a fresh battery.
4. We concluded that something went wrong with the experiment since it didn't give us the results we expected.
