Given parameters:
Initial speed of train = 0m/s
Final speed = 25m/s
time = 20s
Unknown:
Total distance covered = ?
Solution:
Speed is a scalar quantity that has magnitude and no direction.
Mathematically;
Speed = [tex]\frac{distance}{time}[/tex]
distance = speed x time
Input the parameters and solve for distance;
Distance = 25 x 20 = 500m
The distance covered is 500m
A wave has a speed of 23 m/s and a frequency of 13 Hz. What is the wavelength?
Answer:
1.76923077 meters
Explanation:
wavelength is denoted by the letter lambda it is equal to the speed (v) of a wave in a medium (air , water, light) divided by frequency , equals wavelength . so wavelength = v/f or = 23m/s ÷13hz
