Answer:
(a) Tension=28.28 N
(b) Speed=29.14 m/s
Explanation:
Given data
f(frequency)=875 vibration/second
λ(wave length)=3.33 cm=0.0333 m
m(mass)=16.3 g=0.0163 kg
To find
(a) Tension
(b) Speed
Solution
For (b) at what speed the wave travel
For (a) Tension
So screw must adjust such that tension in the wire is 28.28 N
Answer:
The expression for the period of the pendulum is
T=2π√l/g
Explanation
Kindly find attached document for the analysis of the pendulum and the derivation for the period
What is a simple harmonic motion?
Simple harmonic motion is defined as the to and fro motion of an object or a particle whose acceleration is directly proportional to its displacement from a fixed point and is always directed towards that point.
Refer to the diagram shown below.
x = the distance (horizon) that you can see from the balloon,
Because the radius of the earth is 6400 km, and the balloon is 350 n above the earth's surface, therefore
h = 6400 + 0.350 = 6400.35 km.
From the Pythagorean theorem, obtain
x = √(6400.35² - 6400²) = 66.934 km
Answer: Your horizon is 66.934 km (or 66,934 m)
A theory is a system of ideas that isn't exactly proven to be true fully. A law is a description of whatever scientific phenomena you're studying. All you need to know is a law describes, and a theory explains.
