M = 2.2 g = 2.2 x 10⁻³ kg, the mass of the bug.
r = 3.0 cm = 0.03 m, the radial distance from the center.
The angular speed is
ω = 280 rpm
= (280 rev/min)*(2π rad/rev)*(1/60 min/s)
= 29.3215 rad/s
The moment of inertia of the bug is
I = mr²
= (2.2 x 10⁻³ kg)*(0.03 m)²
= 1.98 x 10⁻⁶ kg-m²
Calculate the angular momentum of the bug.
J = Iω
= (1.98 x 10⁻⁶ kg-m²)*(29.3215 rad/s)
= 5.806 x 10⁻⁵ (kg-m²)/s
Answer: 5.806 x 10⁻⁵ (kg-m²)/s
2.496 HZ is the resistance change the resonant frequency.
Given, Supply frequency, f = 60 12
number of poles, P = 4
Full load speed, Ne= 1725 rpm
Synchronous speed; No= 1201= 120X60 = 1800 rpm
P
4
We know the formula for Full load-speed
Ne = N's (1 - Sf)
where se = full load rotor ship
Ne = 1 - SP
SQ = 1- Ne = 1- 1725 = 0.0416 DY 4-16%
1800
SQ= 4. 16 % or 0.0416
Frequency of rotor, fy= Sgif = (0.0416) ( 60 ) = 2.496 Hz
fr = 2.496 HZ

Heat is transferred by a fluid's macroscopic movement, which is known as convection. Weather systems and forced-air furnaces both use this form of transmission. Thus, option A is correct.
<h3>What Convection method of heat transfer warms?</h3>
Convection, as heat is transmitted through the sand's solid structure. Conduction, as the air particles that come into contact with the hot sand travel more quickly.
The heat is transferred inside the fluid during convection. Heat transfer in radiation happens by electromagnetic waves without the use of particles.
Conduction, as heat is transferred using electromagnetic waves Convection, since heat is transferred by air particles without the usage of a medium.
Therefore, Convection, because heat is transferred through the solid sand.
