Explanation:
Answer:
Speed = 300 m/s
Explanation:
Given the following data;
Frequency = 30 Hz
Wavelength = 10 m
To find the speed of the wave;
Mathematically, the speed of a wave is given by the formula:
Substituting into the formula, we have;
Speed = 300 m/s
Changes in the earths ability to reflect sunlight (called the 'albeido') due to clouds and other weather like ice formations set up feedback loops that prevent a perfect equlibrium with the sun.
T = 2,548
What is tension?
Tension occurs due to the direction of pull on the object and along the length of the given rope.
It's S.I. unit is Newton
Tension formula can be represented as
T = mg + ma
T = 200 (9.8 + 1.3 m/s²)
T = 200 (12.74)
T = 2,548
