Answer:
As the mass of a white dwarf increases, the pressure must increase to resist gravity. To do this, the electrons must move faster.
Explanation:
A white dwarf also known as degenerate dwarf is a star or an electron degenerate matter and is as massive as the Sun but only about as large in size as planet Earth.
The maximum mass of a white dwarf is about 1.4 times the mass of the Sun.
Also, as the mass of a white dwarf increases, the pressure must increase to resist gravity and to do this, the electrons must move faster.
B. Infrared waves
C. X rays
D. Cosmic rays
The temperature of a balloon is lowered with liquid nitrogen. The balloon appears to deflate because the gas in the balloon lost energy and condensed. The answer is letter D.
Answer:
300 Btu per hour
Explanation:
given data
area = 100-square foot
thick = 12 inch
R value at 12 = 1.89
R value at 4 = 14.8
inside temperature = 65 degrees F
outside temperature = 15 degrees F
to find out
How many Btu per hour
solution
we get here How many Btu per hour that is express as
Btu per hour = ............1
put here value we get
Btu per hour =
Btu per hour = 299.580
so Btu per hour is 300 Btu per hour
Answer: (D). The unit and direction is missing.
Explanation:
Velocity: Velocity is the speed of the object with direction and it is the vector quantity. The unit of velocity is m/s.
Average velocity: Average velocity is defined as the total distance divided by the total time.
Here,
D = Total distance
T = Total time
According to the question:
The unit and the direction is missing in the cyclist's velocity.
Hence, The unit and direction is missing.
