The statement “When an object is in orbit, it is falling at the same rate at which the Earth is curving” is true. The speed of a satellite orbiting the earth depends only on the mass of the earth and the mass of the satellite.
Answer:
The 8 foot long plank
Explanation: hope this helps :)
B) They are absorbed
C) The change into P-waves
D) They change into L-waves
Answer:
B) They are absorbed
Explanation:
B is correct because S waves can only travel through solid materials. When they hit liquid materials they are absorbed in and undetectable.
Answer:
B) They are absorbed
Explanation:
When they hit the liquid core, S-waves are no longer able to be detected. While P-waves bounce off the liquid core, S-waves are absorbed at the core.
Answer:
Melting of ice is an endothermic process, meaning that energy is absorbed. When ice spontaneously melts, ΔH (change in enthalpy) is "positive". ΔS (entropy change) is also positive, because, becoming a liquid, water molecules lose their fixed position in the ice crystal, and become more disorganized. ΔG (free energy of reaction) is negative when a reaction proceeds spontaneously, as it happens in this case. Ice spontaneously melts at temperatures higher than 0°C. However, liquid water also spontaneously freezes at temperatures below 0°C. Therefore the temperature is instrumental in determining which "melting" of ice, or "freezing" of water becomes spontaneous. The whole process is summarized in the Gibbs free energy equation:

Answer:
We conclude that it is a Bronsted-Lowry acid.
Explanation:
Hello! Let's solve this!
According to Bronsted-Lowry an acid is a chemical species that is capable of yielding protons and a Bronsted-Lowry base is a chemical species capable of accepting protons.
In this case we see that sulfuric acid (H2SO4) loses a proton to become HSO4.
We conclude that it is a Bronsted-Lowry acid.
Answer: Option (B) is the correct answer.
Explanation:
The radiation in which waves of electromagnetic field travel or propagate through the space and carries electromagnetic radient energy is known as electromagnetic radiation.
The relation between energy and frequency is as follows.
............ (1)
where, E = energy
h = plank's constant
= frequency
Therefore, the frequency of the emitted radiation is directly proportional to its energy.
Also, frequency is proportional to c over wavelength. The relation is as follows.
........ (2)
where, = frequency
c = speed of light
= wavelength
Placing the value of frequency from equation (2) to equation (1) as follows.
Thus, the wavelength of the emitted radiation is inversely proportional to its energy.
Answer:
The amount of energy added to rise the temperature Q = 17413.76 KJ
Explanation:
Mass of water = 52 kg
Initial temperature = 68 °F = 20° c
Final temperature = 212 °F = 100° c
Specific heat of water
Now heat transfer Q = m × C × ( - )
⇒ Q = 52 × 4.186 × ( 100 - 20 )
⇒ Q = 17413.76 KJ
This is the amount of energy added to rise the temperature.
