Answer: Conduction- Touch transfer heat and Earth warms air
Convection- liquid/gas transfers heat and warm air rises
Radiation- Sun heats Earth and Waves transfer heat
Explanation:
Answer:
The velocity of the particle = -1.92 m/s
The speed of the particle = 5.72 m/s
Explanation:
Given equation of motion;

Velocity is defined as the change in displacement with time.

The distance traveled by the particle in 5 s:

The speed of the particle when t = 5s

Putting together two distinct 50 dB sound, do not create a 100 dB sound. Since decibels are logarithm of energy, creating two sounds together only makes the energy increase but the logarithm only goes up by somehow little. So increasing the sound by 10 dB, only makes it 10000 times louder because each 10 dB increase in sound makes the sound 10 times louder.
Twice as loud is an increase of 10Log (2) = 3.01 dB. So, 53,01 dB is twice as loud as 50dB.
Answer:
(4.31±0.38) million Solar masses.
Explanation:
The galactic center is the center of the milky way around which the galaxy rotates. It is most likely the location of a supermassive black hole which has a mass of (4.31±0.38) million Solar masses. The location is called Sagittarius A*.
As there is interstellar dust in our line of sight from the Earth infrared observations need to be taken.
