Wave speed = (wavelength) x (frequency)
We know the wavelength, but we don't know the frequency. How can we find the frequency ? "Here frequency frequency."
We know the period, and frequency is just (1 / period). So . . .
Wave speed = (wavelength) / (period)
Wave speed = (2.1 meters) / (9.4 seconds)
Wave speed = (2.1 / 9.4) m/s
<em>Wave speed = 0.223 m/s</em>
Answer:
30.24m
Explanation:
When adding numbers together, we round to the smallest number of decimal places of the numbers, which is 2 decimal places in this case.
24.686m + 2.343m + 3.21m = 30.23<u>9</u> m
≈ 30.24m (round to 2 d.p.)
When you round numbers to a certain digit (hundredth in this case), you would want to look on the digit on its right (thousandth in this case). If that digit is 1-4, you round the digit down. If that digit is 5-9, you round the digit up. Since the digit in the thousandths place is 9, you round the hundredth digit up from 3 to 4.
V = f(lambda)
5/1 = lambda
lambda = 5

Answer:
C. a quantity with magnitude and direction
Explanation:
These are the options for the question
A. a quantity of magnitude only
B. a quantity with direction only
C. a quantity with magnitude and direction
D. a quantity with no units.
Velocity is the distance cover per time, it is the rate at which an object change its position with respect to time.
Velocity is a vector quantity unlike speed which is a scalar quantity, velocity is the speed of an object with a specific direction.
For instance, the distance cover by Mr. A is 10m, at 2 seconds, this show a magnitude and direction, then velocity here is 10/2=5m/s
Answer:
I think it is difficult to determine what has caused climate change in the distant past because it must have been a long time ago so geologists can't carry out different experiments and figure out what gases the planet had conjured, so geologists can only make predictions based off the evidence they currently have from what the planet looked like before. The planet must have changed over the years, therefore the climate has also changed in the future, so they cannot work with how the planet looked in the past.
