Answer:
Net force.
Explanation:
All of the forces acting on an object combine to create a net force.
Answer: E) all of the above
Explanation:
Frequency is the number of vibrations in one second. It is also defined as the number of crests that pass a point in a given time.
The frequency and the wavelength has an inverse relationship.
Frequency is measured in cycles per second or Hertz(Hz).
The relationship between wavelength and frequency of the wave follows the equation:
where,
= frequency of the wave
c = speed of light
= wavelength of the wave
Thus all the given statements are true.
3 hours and 40 minutes is equivalent to 3.667 hours. If a woman must have run another marathon (of 26.2 miles) within that time, then her minimum average speed in mph can be calculated by dividing the distance by time:
26.2 miles / 3.667 hours = 7.145 miles per hour
