Select all that apply. Which of the following energy sources are in some way derived from the Sun? geothermal nuclear wave biomass
I Think It Is Wave And BioMass
In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term "hot Jupiter"). The orbit was just 19 the distance of Mercury from our sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular). What is the mass of the star? Express your answer (a)in kilograms and (b)as a multiple of our sun's mass.
Use Kepler's 3rd Law
T^2 = k R^3
where k = 4(pi)^2/ GM
G =gravitational constant = 6.67300 × 10-11 m3 kg-1 s-2
M = mass of this new planet
pi = 3.14159265
T =3.09 days = 266976 seconds
R = (579,000,000km)/9 = 64333333.3 km
Solve Kepler's 3rd Law for M. Your answer will be in kg
mass of the sun = 1.98892 × 10^30 kilograms
Form the ratio

Which is an example of transforming potential energy to kinetic energy? Check all that apply. changing thermal energy to electrical energy changing chemical energy to thermal energy changing nuclear energy to radiant energy changing radiant energy to electrical energy changing mechanical energy to chemical energy
All of the following are possible sources of error in a scientific investigation except for A. Measuring the change in temperature incorrectly B. Manipulating the wrong variables in the experiment C. Reviewing previously published studies before the experiment D. Completing only one trial in the experiment
Your answer would be C my friend
Which statement is NOT true? a. water plays an important role in the control of body temperature b. water helps carry nutrients to cells and waste products away from cells c. people need a minimum of 10-12 glasses of water each day d. soups, fruits, vegetables, and meats are sources of water
There are two ways the Scientific and the Normal.( for a lack of better word)
Normal: The heat escapes into space.
Scientific: As the molecules of the element heat up and vibrate for long periods they lose heat so they return to their original temperature (at least try to)
Crustal plates scrape and slide past each other along faults at their boundaries. For example, the Pacific and North American Plates slide past each other along the San Andreas Fault in northern California. What natural hazard usually results when crustal plates scrape and slide past one another? A. hurricanes B. tsunamis C. tornadoes D. earthquakes 50 POINTS!
The answer is D I just took the test on study island
and there is an explanation
When crustal plates scrape and slide past one another, they release built-up energy. This energy travels through the Earth as earthquakes.
hope this helps you
The difference between temperature and thermal energy is that temperature measures the average kinetic speed of molecule and thermal energy is the total kinetic energy of all particles in a given substance.
What happens when the electron moves from the first energy level to the second energy level? Energy is absorbed, and an emission line is produced. Energy is released, and an emission line is produced. Energy is absorbed by the atom. Energy is lost from the atom.
Emission lines occur only in the case of transitions from higher to lower energy levels in which energy is emitted.
PLEASE HELP FAST??!! Which statement is true about the electromagnetic spectrum? A. The visible Spectrum includes radio waves, light and gamma rays. B. Same wave lengths of light corresponding to different colors. C. It contains a spectrum of visible light plus a wide array of nonvisible forms of radiation. D. The waves travel at a speed of 2.998 *10^5 m/s
The electromagnetic spectrum contains visible light along with many other components such as radio waves, microwaves, ultraviolet rays and gamma rays.
The water has potential energy when it is at the top of the falls which is converted into kinetic energy as it falls.
E = nhc / λ
Also, Power = Energy / time
E = 20 x 10⁻³ x 60 x 60
E = 108 J
108 = (2.29 x 10²⁰ x 6.63 x 10⁻³⁴ x 3 x 10⁸) / λ
λ = 4.22 x 10⁻⁷ m
Which of the following might be considered a viable application of a radioactive tracer? It can be more then one? A) adding a stream of radioisotopes to waste water to examine where pollution goes when it flows into the ocean B) embedding a radioactive plug in a valuable necklace so that its location can be determined using a Geiger counter C) placing radioactive sources around a room to trace the location of people as they move through the room d.) filling a pipeline with radioactive gas to see if it contains any leaks
Which of the following is true of both nuclear fusion and nuclear fission? a. They both require a high energy input. b. They both occur without byproducts. c. They both have a high energy output. d. They both involve large atoms breaking into smaller atoms.
Both processes release tremendous amounts of energy.
B. Greater energy
Fast moving water is very energetic as its can displace very large rocks, boulders and make pebbles and sand out of them through the process r erosion. Fast moving water have kinetic energy, it opposes anything that come in its way. As river make its own channel by eroding plane. Many antecedent rivers have make their channel by cutting large mountains too.
