Answer:
Explanation:
From the given information:
The torque produced due to the force can be expressed as:
where;
= torque
F = force exerted
r = lever's arm radius
= 
= 60 N.m
However, equating the torque with the moment of inertia & angular acceleration, we use the equation:
= I∝
60 Nm = I × 120 rad/s²
I = 60 Nm/120 rad/s²
I = 0.5 kg.m²
Answer: A a mechanical wave travels through empty space, while an electromagnetic wave travels through matter.
Explanation: A mechanical wave travels through empty space, while an electromagnetic wave travels through matter. A mechanical wave has a short wavelength, while all electromagnetic waves have long wavelengths.
Because reliable conclusions are trustworthy and applicable.
Reliable is officially defined as being "able to be trusted to do or provide what is needed." and has been clearly shown in context of the first statement. Being interesting is not always a quality of something with reliability as what the second statement suggests. Also, reliable conclusions are always a part in scientific endeavor.
