It will be 80 miles and it can be done only in 16 min
A if it is one answer and if it’s multiple choice A and D
Answer:
540m/s
Explanation:
Given parameters:
Frequency of the wave = 18000Hz
Wavelength of the wave = 0.03m
Unknown:
How fast is the wave traveling = ?
Solution:
How fast the wave is traveling is a measure of the speed of the wave;
Speed of wave = frequency x wavelength
Now insert the given parameters and solve;
Speed of wave = 18000 x 0.03 = 540m/s
A higher temperature, stiffer materials, and less dense materials increase the speed of sound.
One of the key areas of science is the study of acceleration and deceleration. Any object's rate of changing velocity is referred to as its acceleration, and a negative acceleration value is referred to as deceleration.
Using beginning velocity of 50 miles per hour,
It's going to
Final speed: 73.33 ft/s, v = 0, and a2: -22 ft/s2.
Utilize the formula: v2 = v0 + 2as
n 0 = 5377.29 + (-44) s
s =5377.29/44 = 122.21 ft
v2 = u2 + 2as is the third equation of motion. We are already aware that distance is equal to average velocity times time. Either v2 = u2 + 2as or 2as = v2 - u2. The third equation of motion connects the particle's final velocity (v), initial velocity (u), constant speed (a), and displacement (S).
Speed is defined as the ratio of distance travelled to the amount of time required to cover that distance.
