speed of 5,000 meters per second?
Answer:
Period T = 0.1 second
Explanation:
Given that the
wavelength = 500 meters
speed V = 5000 meters per second
The wave speed is the ratio of wavelength to period of the wave. That is,
V = λ/T
Where
V = wave speed (m/s)
λ = wavelength (m).
T = period (s)
Using the formula above gives
5000 = 500/T
Make T the subject of formula
T = 500/5000
T = 0.1 s
B. ice cube
Answer:
oxygen
Explanation:
I just did the assignment and that was the right answer.
What's the formula for this problem?
For this problem, we use the following expression:
Speed = distance / time
Distance = Speed * timeSince the problem tells us the speed of the plates, we know that
Speed_plates = 6.0 cm/year
Which is equal to
Speed_plates = 6.0 cm/365 days = 6.0 cm/(365*24 hours)
Speed_plates = 6.0 cm/(365*24*60 minutes)
Speed_plates = 6.0 cm/(365*24*60*60 seconds)
Speed_plates = 190.258 E -9 cm / s
We multiply by 25, to get the distance traveled after 25 seconds
Distance traveled = 4.756 E-6 cm
constant.
B) The car is traveling at a constant rate of speed so it is not accelerating and
the velocity does not change.
C) Acceleration is the change in velocity so the car is experiencing a change
in velocity and it is accelerating.
D) The car is traveling at a constant rate of speed so it is not accelerating but
the velocity changes because the direction the car travels is constantly
changing
Answer:
B) The car is traveling at a constant rate of speed so it is not accelerating and the velocity does not change.
Explanation:
Since the driver is maintaining his speed, therefore velocity is constant and there is no acceleration because acceleration is the rate of change of speed with time.
