Answer: Tension = 47.8N, Δx = 11.5×
m.
Tension = 95.6N, Δx = 15.4×
m
Explanation: A speed of wave on a string under a tension force can be calculated as:
is tension force (N)
μ is linear density (kg/m)
Determining velocity:
0.0935 m/s
The displacement a pulse traveled in 1.23ms:
Δx = 11.5×
With tension of 47.8N, a pulse will travel Δx = 11.5× m.
Doubling Tension:
|v| = 0.1252 m/s
Displacement for same time:
15.4×
With doubled tension, it travels 15.4× m
Answer: vf = 51 m/s
d = 112 m
Explanation: Solution attached:
To find vf we use acceleration equation:
a = vf - vi / t
Derive to find vf
vf = at + vi
Substitute the values
vf = 3.5 m/s² ( 8.0 s) + 23 m/s
= 51 m/s
To solve for distance we use
d = (∆v)² / 2a
= (51 m/s - 23 m/s )² / 2 ( 3.5 m/s²)
= (28 m/s)² / 7 m/s²
= 784 m/s / 7 m/s²
= 112 m
Answer:
Oh wow so this is why you stole those points from me
Explanation:
High amplitude sound would be music, radio, or earthquakes.
Low amplitude sound would be a breeze or wind.
Strong nuclear force is most like electrical force because they are both related to distance statement best describes the similarities between fundamental forces.
<u>Option: D</u>
<u>Explanation:</u>
There are four forms of fundamental forces in nature. They are called gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. Strong nuclear force is a spin-dependent, charging-independent force that arises into being due to the mutual association of gluons binding protons and neutrons.
It is also hundred times more powerful than electromagnetic force. Poor nuclear capability comes into being during radio-active decay. This force is due to the interaction of 'w' and 'z' bosons (particles such as protons and neutrons with integral or zero spin) that are heavier in nature. The function of this force is to turn protons into neutrons and vice versa.
