A. The flow of energy from Earth's interior to the surface is about 50 terawatt (1 terawatt = 1e12 joule/sec). This is the energ

y that gives Earth an active surface geology (hot springs, volcanoes, plate tectonics, etc). Roughly half of this geothermal is from the energy produced by radioactive decay, and roughly half is from the energy left from the formation of the hot Earth.
Estimate how much geothermal energy reaches Earth’s surface in one day (in Joule).
b. Estimate humanity’s current consumption of energy in one day (in Joule).
c.Assuming 100% efficiency of extracting geothermal energy, estimate the ratio of geothermal energy to human's current annual world consumption of energy.

A) The amount of geothermal energy that reaches Earth's surface in one day is : 43.2 * 10¹⁷ joules

B) Humanity's current consumption of energy is; 71.4 GJ per individual.

C) Ratiois ; 60.5 * 10⁶ Joules

<u>Given data :</u>

Amount of energy flow = 50 terawatt =  50*10¹² joule/sec.

<h3>Determine the geothermal energy that reaches the earth</h3>

Since the geothermal energy reaches the earth in a single day

Energy = power * time

Time = 24 hours ( 1 day ) = 86400 secs.

Energy = 50*10¹² joule/sec * 86400 secs

            = 43.2 * 10¹⁷ joules

<h3 /><h3>B) Estimating humanity's current consumption of energy in one day.</h3>

Humanity's current consumption of energy in one day is estimated to be 71.4 GJ per individual.

<h3>C) Determine the ratio of geothermal energy to human's current annual consumption </h3>

Geothermal energy / human current annual consumption

= 43.2 * 10¹⁷ Joules / 71.4 * 10⁹ Jolues

= 60.5 * 10⁶ Joules

Hence we can conclude that A) The amount of geothermal energy that reaches Earth's surface in one day is : 43.2 * 10¹⁷ joules

B) Humanity's current consumption of energy is; 71.4 GJ per individual.

C) Ratiois ; 60.5 * 10⁶ Joules

NEED HELP ASAP Does this Intro simulation support the law of conservation of energy? Use evidence to explain why or why not.
TiliK225 [7]

is this the skater one? If so, it does support the law of conservation of energy because at the top of the ramp the skater has the same amount of potential energy their total energy and as the skater goes down the ramp their potential energy lowers as their kinetic energy rises.

A metal rod with a length of 22.0cm lies in the xy-plane and makes an angle of 37.9 degrees with the positive x-axis and an angl
Shtirlitz [24]

Answer:

Induced emf in the rod is, \epsilon=0.08262\ V

Explanation:

Given that,

Length of the rod, L = 22 cm = 0.22 m

Angle with x axis is 37.9 degrees with the positive x-axis and an angle of 52.1 degrees with the positive y-axis.

L=0.22(cos37.9\ i)+0.22(sin37.9\ j)

L=(0.173\ i+0.135\ j)\ m

Velocity of the rod, v = 6.8i m/s

Magnetic field, B=0.170i-0.24j-0.09k

The formula for the emf induced in the rod is given by :

\epsilon=(v\times B){\cdot}L

\epsilon=(6.8i\times (0.170i-0.24j-0.09k)){\cdot} (0.173\ i+0.135\ j)      

\epsilon=(0.612j-1.632k){\cdot}(0.173i+0.135j)      

\epsilon=0.08262\ V

So, the magnitude of the emf induced in the rod is 0.08262 volts. Hence, this is the required solution.

Surrounding a magnet is a magnetic field. Surrounding an electron is an electric field. Surrounding Earth is
trasher [3.6K]

Answer: B. A gravitational field

Explanation:

Surrounding earth is gravitational field. Gravitational field is a region of space were gravitational force can be felt and gravitational force is the gravitational pull on the surface of the earth. The presence of this gravity is what allow us to be able to walk freely without falling. It also make us jump up and be able to land back on the ground. Assuming there are no force of gravity in the surface of the earth, there won't be any possibility of landing back on the ground after jumping.

Two objects in physical contact with each other are in thermal equilibrium when they reach the same temperature and an exchange of heat energy no longer occurs.<span> According to HyperPhysics, the relation of thermal equilibrium follows the Zeroth Law of Thermodynamics, which states that “if two systems are at the same time in thermal equilibrium with a third system, they are in thermal equilibrium with each other.” </span>
