Physical science is the study of matter and energy, and the relationship between matter and energy.

E. The study of matter and energy, and the relationship between matter and energy

<u>Explanation:</u>

The study of issue and vitality and the associations between physicists concentrate such subjects as gravity, light, and time. Albert Einstein, a well known physicist, built up the Theory of Relativity.  

Material science is the investigation of issue and vitality at all scales—from the littlest particles of the issue to the whole universe.  

A geologist has practical experience throughout the entire existence of Earth. A sea-life scholar contemplates sea plants and creatures. A physicist ponders matter, vitality, and how they are connected.  

There are three primary parts of science: physical science, Earth science, and life science. Physical science is the investigation of lifeless common items and the laws that administer them. It incorporates material science, science, and cosmology.

A ceiling fan has three blades. The moment of inertia of a blade is 0.2kgm^2. The net torque exerted on fan blades is 8Nm. Find
olchik [2.2K]

Answer:

(A) the angular acceleration of the blades is 13.33 m/s.

Explanation:

Given;

moment of inertia of a blade, I = 0.2 kgm²

net torque exerted on fan blades, ∑τ =  8Nm

Torque is given as product of moment of inertia and angular acceleration;

τ = Iα

where;

α is the angular acceleration

Since there are three blades of the ceiling fan, the net torque is given as;

∑τ = (3I)α

∑τ = 3Iα

α = ∑τ / 3I

α = (8) / (3 x 0.2)

α = 13.33 m/s

Therefore, the angular acceleration of the blades is 13.33 m/s.

Which tem decorbes the perceived frequency of a sound wave?
JulsSmile [24]

Pitch

Explanation:

The pitch of a sound wave is the perceived frequency of a sound wave.

The quality of sound that makes it discernible to the ear is the pitch.

  • Sound wave is a longitudinal wave that is transmitted by series of rarefaction and compression.
  • Pitch helps to distinguish between the different sound qualities.
  • Pitch is how high or low sound is perceived.
