Answer:

w = 0.886 rad / s

Explanation:

Angular and linear variables are related

       a = α r

where a is the linear acceleration, α the angular acceleration and r the radius of gyration

         α = a / r

the angular velocity we can find it

         w² = w₀² + 2 α θ

the initial angular velocity is zero, the angles to be horizontal is

    θ = π/ 2  rad

     

we substitute

          w = √ 2 a / r  θ

we calculate

          w = √ (2 3/12 π/2)

          w = 0.886 rad / s

What happened to a apple's weigh as the plane rose up toward the sky?
uysha [10]

Okay, I don't know if this question is supposed to be a trick question or not. The weight of the apple does not change as the plane travels up the atmosphere, but the MASS changes. Weight doesn't change no matter what environment you're in, but the mass changes in different environments. In this case, the weight is constant but the mass is decreasing as you go higher up.

What property of an object is related to the average kinetic energy of the particles in that object
Butoxors [25]

Answer:

Temperature of the object

Explanation:

According to kinetic theorem of gases, the temperature of a gas is a measure of the of the average kinetic energy of the gas particle.

A particle can either exist as solid, liquid or gas.

For solid, the particles are fixed as they rotates and vibrate about a mean position.

The particle of an object is a solid particle.

In accordance to kinetic theorem, the temperature of an object related to the average kinetic energy of the particles in the object.\

Temperature: This can be defined as the degree of hotness or coldness of an object.

Define scalar quantity​
joja [24]

Answer:

Scalar quantities are physical quantities which have a magnitude and direction.

e.g. in 5 km, 5 is the magnitude(number) and km is the unit.

some scalar quantities are mass, length, distance, speed, power, energy, temperature etc.
