Answer:

conduction and convection

Explanation:

Sun is a huge ball of gases- Hydrogen and Helium. Nuclear fusion reaction in the core powers the sun. The heat from the core is transferred to photo-sphere via two modes- convection and conduction.

Conduction is the mode of heat transfer when the particles vibrate at a their fixed position. The particles collide with the neighboring particles and transfer heat. More the temperature, with particles vibrate with greater energy. There is direct contact between particles. conduction happens in solids, liquids and gases.

Convection is the mode of heat transfer in fluids. The fluid heats up near the source and expands. Due to its less density, it rises up and the cool fluid from top rushes to take its place. This process continues.

Convection currents can be observed on the surface of the sun. Due to convection currents, sun has granular texture.

Answer:

The force of gravity exerts a downward force. The floor exerts an upward force. Since these two forces are of equal magnitude and in opposite directions, they balance each other.

What happens when a resultant electric field exist in conductor

klio [65]

Answer:

When an electric field exists in a conductor a current will flow.

This implies a voltage difference between two points on the conductor.

Electrostatics pertains to static charge distributions.

That means that an object such as a charged spherical conductor will be at the same potential (voltage) on both its outer and inner surfaces.

You and a friend frequently play a trombone duet in a jazz band. During such performances it is critical that the two instrument

Rashid [163]

Answer:

f₂ = 468.67 Hz

Explanation:

A beat is a sudden increase and decrease of sound. The beats are produced through the interference of two sound waves of slightly different frequencies. Now we have the following data:

The higher frequency tone = f₁ = 470 Hz

No. of beats = n = 4 beats

Time period = t = 3 s

The lower frequency note = Frequency of Friend's Trombone = f₂ = ?

Beat Frequency = fb

So, the formula for beats per second or beat frequency is given as:

fb = n/t

fb = 4 beats/ 3 s

fb = 1.33 Hz

Another formula for beat frequency is:

fb = f₁ - f₂

f₂ = f₁ - fb

f₂ = 470 Hz - 1.33 Hz

A train traveling at 6.4 m/s accelerates at 0.10 m/s 2 over a distance of 100 m. How large is the train’s final velocity?

klasskru [66]

The final velocity of the train at the end of the given distance is 7.81 m/s.

The given parameters;

initial velocity of the train, u = 6.4 m/s
acceleration of the train, a = 0.1 m/s²
distance traveled, s = 100 m

The final velocity of the train at the end of the given distance is calculated using the following kinematic equation;

v² = u² + 2as

v² = (6.4)² + (2 x 0.1 x 100)

v² = 60.96

v = √60.96

v = 7.81 m/s

Thus, the final velocity of the train at the end of the given distance is 7.81 m/s.
