Answer:
Amplitude is the vertical distance between a ridge and the midpoint of the wave.
Explanation:
A mechanical wave is a disturbance that travels through a material or substance that is a medium of the wave. For example, when a tense string is pressed, the disturbance caused spreads along it in the form of a wave pulse. The disturbance in this case consists in the variation of The Shape of the string from its equilibrium state
it is important to know:
Crest: the crest is the highest point of this amplitude.
Period: the period is the time it takes the wave to go from one point of maximum amplitude to the next.
Amplitude: amplitude is the vertical distance between a crest and the midpoint of the wave.
Frequency: number of times that vibration is repeated.
Valley: it is the lowest point of a wave.
Wavelength: distance between two consecutive ridges of this size.
Transverse wave velocity.-
The propagation speed of a wave on a string (v) is proportional to the square root of the string tension (T) and inversely proportional to the square root of the linear density (μ) of the string:
Answer: Kinetic Energy
Explanation:Kinetic energy is the energy of motion. All moving objects have kinetic energy.
Answer:
Time=15,Mass=3,Acceleration due to gravity=10,Height=50,Power=?.
Power=mgh/t.....which is 3×10×50=1500/15=100Watts.
The instant it was dropped, the ball had zero speed.
After falling for 1 second, its speed was 9.8 m/s straight down (gravity).
Its AVERAGE speed for that 1 second was (1/2) (0 + 9.8) = 4.9 m/s.
Falling for 1 second at an average speed of 4.9 m/s, is covered <em>4.9 meters</em>.
ANYTHING you drop does that, if air resistance doesn't hold it back.
Answer:
Distance, S = 15m
Explanation:
Given the following data;
Mass = 4kg
Force = 10N
Initial velocity = 5m/s
Final velocity = 10m/s
To find the distance;
First of all, we would calculate the acceleration
Force = mass * acceleration
10 = 4*acceleration
Acceleration = 10/4
Acceleration = 2.5m/s²
Now to find the distance, we would use the third equation of motion.
Where;
- V represents the final velocity measured in meter per seconds.
- U represents the initial velocity measured in meter per seconds.
- a represents acceleration measured in meters per seconds square.
S represents the displacement measured in meters.
Substituting into the equation, we have;
10² = 5² + 2*2.5*S
100 = 25 + 5S
5S = 100 - 25
5S = 75
Distance, S = 75/5
Distance, S = 15m
