About how much longer can the Sun continue to generate energy by nuclear reactions in its core?

Physics
1 answer:
QveST [7]3 years ago
5 0

Answer: 5billion years

Explanation: The sun produces energy through radioactive fusion reaction.

Nebula theory states that the gaseous particles of the Earth collapsed as a result of its own gravity which continuously lead to fusion reaction for the production of nuclear energy.

The Core of the Sun is that area up to 25% from the radius of the sun,here the pressure here range up to 250million atmosphere containing mainly hydrogen which gets converted in Helium molecule. The core is the center for energy production accounting for more than 98%, nuclear energy is transmitted at about 4.3million metric tons per second.

Calculate the difference in blood pressure between the feet and top of the head for a person who is 1.70 m tall.
cupoosta [38]

Answer:

P_2 - P_1 = 1.8 * 10^4\ Pa

Explanation:

Given

Height (h) = 1.70m

Required

Determine the difference in the blood pressure from feet to top

This is calculated using Pascal's second law.

The second law is represented as:

P_2 = P_1 + pgd

Subtract P1 from both sides

P_2 - P_1 = pgd

Where

p = blood\ density = 1.06 * 10^3kg/m^3

g = acceleration\ of\ gravity = 9.8N/kg

d =height = 1.70m

P2 - P1 = Blood Pressure Difference

So, the expression becomes:

P_2 - P_1 = 1.06 * 10^3 * 9.8 * 1.70

P_2 - P_1 = 17659.6Pa

P_2 - P_1 = 1.8 * 10^4\ Pa

Hence, the difference in blood pressure is approximately 1.8 * 10^4\ Pa
