Answer:
Explanation:
lower the temperature -the higher the temp the more energy the molecules absorb. The more energy they have the more they move
Answer: 0.002 newtons
===================================================
Work Shown:
I'm assuming you meant to write "at 20 m/s^2" at the end. If so, then,
0.10 grams = 0.10/1000 = 0.0001 kg
m = 0.0001 kg = mass
a = 20 m/s^2 = acceleration
F = ma .... newton's second law
F = 0.0001*20
F = 0.002
The force required is 0.002 newtons
Answer:
The force is
Explanation:
From the question we are told that
The tangential resistive force is 
The mass of the wheel is m = 1.80 kg
The diameter of the wheel is 
The diameter of the sprocket is 
The angular acceleration considered is 
Generally the radius of the wheel is

=> 
=> 
Generally the radius of the sprocket is

=> 
=> 
Generally the moment of inertia of the wheel is mathematically represented as

=> 
=> 
Generally the torque experienced by the wheel due to the forces acting on it is mathematically represented as

Here
is the force acting on the sprocket
So


Generally the torques that will cause the wheel to move with
is mathematically represented as

So

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
