A relationship exists and the numbers cause one another can be said about two numbers that have either a positive or negative correlation
Option : C
<u>Explanation:</u>
When two numbers have positive correlation, they move in the same direction. If the first variable increases, the second one also increases and if one variable decreases the other one also decreases.If the two numbers have negative correlation, the two numbers move in opposite directions.
A relationship exists between two numbers and the number cause one another. A correlation means that changing one variable affects the other. Correlation among variables need not necessarily imply causation. Positive correlations are mostly used in Finance and stock markets.
Answer:
NO
Explanation:
I=mr^2 this means moment inertia depends upon mass and square of radius or distance.
Power in physics is work done over time. So the answer is Power is the rate at which work is done.
Answer:
Speed = 2.4 m/s
Explanation:
As given in question,
Frequency of the wave = 4 Hz
The wavelength of the wave = 60 cm
As we know,
1 cm = 0.01 m
=>60 cm = 0.6 m
So, the wavelength of the wave = 0.6 m
speed of wave = wavelength x frequency
= 0.6 m x 4 Hz
= 2.4 m/s
Hence, the velocity of wave vibrating with 4 Hz frequency and wavelength of 60 cm is 2.4 m/s.
