The mass of the object is 0.0076 kg
Explanation:
The frequency of a mass-spring system (simple harmonic motion) is given by
where
f is the frequency
k is the spring constant
m is the mass
For the mass-spring system in this problem, we know:
k = 30 N/m is the spring constant
f = 10 Hz is the frequency
Solving the equation for m, we find the mass:

Answer: 8000N
Explanation: since it is frictionless that means it has 100% efficiency therefore the mechanical advantage is 1 meaning the load equals to the effort
The correct answer is<span> The earth casts a shadow on the moon
The Earth casts a shadow on the moon and that's why we can't see the remaining parts. The parts that we can see are what we call the lunar phases.</span>
ω = ?
mass = 45.8kg
r = 0.512m
E = 2.99*10⁹J
Kinetic Energy of rotation = I * ω²
K.E = I * ω²
I = ½ m*r²
I = ½ * 45.8 * (0.512)²
I = 6.0kgm²
K.E = ½ * I * ω²
ω = √(2K.E / I )
ω = √[( 2* 2.99*10⁹) / 6]
ω = 3.157*10⁴ rad/s
Newton is the unit of force, while force is a pull or push acting on an object
