Answer:
391.67Hz
Explanation:
The fundamental frequency formula in string is expressed as;
Fo = V/2L
V is the velocity of the wave = 329m/s
L is the length of the string = 42cm = 0.42m
Substitute
Fo = 329/2(0.42)
Fo = 329/0.84
Fo = 391.67Hertz
Hence the fundamental frequency of a mandolin string is 391.67Hz
Answer:
Acceleration is the rate of change of velocity. If an object is changing its velocity, its speed, or changing its direction, then it is said to be accelerating.
Explanation:
when you change directions or speed up you are accelerating (or decelerating) and when you change directions or speed its called velocity.
Answer:d
Explanation:
Given
Initially, the ice cube is floating over the water
When the cube is pressed to touch the bottom, it is submerged fully
Therefore more buoyant force is acting on it
At first, a part of the volume is submerged in the water, so the buoyant force is less, but as the entire cube is immersed in the water, the buoyant force increases.
Answer:
58.8NM-²
Explanation:
The pressure is the product of density,depth(height) and acceleration due to gravity
here the density of water is 1gm-³ it a constant so it not given
pressure= 6×9.8×1
pressure = 58.8NM-²
Because of the location of Mg on the periodic table.
