The effects of the thin atmosphere are that the surface of the planet is going to be much hotter and not only that but also more radioactive than a planet with a thicker atmosphere. The thick atmosphere on other planets prevents a lot of radiation from going straight to the surface of the planet.

How does the current in a resistor change if the voltage across the resistor is
increased by a factor of 2?
If the voltage across a resistor is increased by a factor of two, the current in the resistor doubles.
What is ohm’s law?When all physical parameters and temperature are constant, Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
This current-voltage connection may be expressed mathematically as,
The Equation of Ohm's Law;
V∝I
V'∝I'
Hence, if the voltage across a resistor is increased by a factor of two, the current in the resistor doubles.

Michael stands upright and allows his right arm to swing back and forth, naturally and without forcing, like a pendulum. He measures the time for 21 oscillations (complete cycles) to be 28.1 s. Assume his arm (length L) behaves as a simple pendulum, with an effective length of 2/3 L. Find the length of his arm, L.
Answer:

The length of his arm, L = 0.67 m.
What is time period?
A basic pendulum consists of a point mass hung by a tightly supported, weightless, and inextensible string.
T = 2π√ L/g, where L is the pendulum's length and g is the acceleration brought on by gravity, is the formula for a pendulum's period.
Given in the question the time for 21 oscillations (complete cycles) to be 28.1 s. Assume his arm (length L) behaves as a simple pendulum, with an effective length of 2/3 L.
T = 2π√ L/g
T = 2π√2l/3g
T = 28.1/21
T = 1.33
2π√2l/3g = 1.33

Kinetic and Potential energy
The main difference between potential and kinetic energy is that one is the energy of what can be and one is the energy of what is. In other words, potential energy is stationary, with stored energy to be released; kinetic energy is energy in motion, actively using energy for movement.
The muscular system consists of exclusively this kind of tissue.
Answer:B
Explanation:
Each muscle or organ is composed of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. Thus, the muscular system consists of all types of tissue.
What is the muscular system?The Muscle fibers are specialized cells that make up the muscular system. Its ability to contract is its main characteristic. Muscles that are attached to bones, internal organs, or blood arteries are what move things. Muscle contraction is the primary cause of almost all bodily movement. A skeletal muscle on its whole is a part of the muscular system.
Muscle cells, also known as muscle fibers or monocytes (mostly in skeletal and cardiac muscle), make up the majority of the organs that make up muscles (mainly in smooth muscle).
By contracting and pushing food to the small intestine through a process known as peristalsis, the muscles surrounding the stomach aid in the flow of food through the digestive system.

During hypnosis, people:
A. can accurately recall memories of early childhood and infancy.
B. lose all awareness of their surroundings.
C. temporarily suspend their sense of initiative.
D. are in a deep trance, which is similar to stage 3 NREM sleep.
During hypnosis, people temporarily suspend their sense of initiative. Hence, option (C) is correct.
What is hypnosis?
According to one definition, hypnosis is "a waking state of awareness, (or consciousness), in which a person's attention is diverted from his or her immediate surroundings and is consumed by interior experiences such as feelings, cognition, and images." In order to induce hypnosis, the subject must concentrate and become sufficiently absorbed in their imagination. A hypnotic world is created by the physician and patient through the use of suggestions and their acceptance.
Our everyday 'trance' states include things like becoming lost in a good book, driving down a familiar route without being aware of it, being in prayer or meditation, or engaging in a mindless or creative task. Our conscious awareness of our surrounds and an inner awareness exist on a continuum, thus even though one's emphasis is mostly internal in these states, one does not necessarily lose all awareness of the outside world.

Would you expect the spectrum of a blackbody radiator to have peaks and valleys like the spectrum of WF4-358? Why or why not? Define blackbody radiators in your answer.
The Planck model for the black body and the emission spectrum of the atoms allows to find the results for the peaks in the spectrum of stars is:
The general shape is that of a black body and the peaks are due to chemical compounds or elements in the star.
The stars are very hot celestial bodies by nuclear fusion processes, in a good approximation they approximate an ideal body that absorbs or emits all the radiation called black body.
A black body is a cavity in thermal equilibrium at a dated temperature with a small hole, this hole is the so-called black body and its emission spectrum was explained by Planck, with the assumption that the energy is
E = h νν
Where h is Planck's constant and ν is the frequency of the radiation. In the attachment we see the emission spectrum of a black body for various temperatures.
If in the material under study we have in addition the emission characteristics of some elements, it is energy appears as peaks in the emission spectrum and as black bands o valley in an absorption spectrum, therefore the existence of the structure is in a test of the existence of chemical elements within the stars.
In the attachment we can see the spectrum of a dwarf star where we can appreciate the spectrum of the black body and the emission and absorption lines of the chemical elements inside the star.
In conclusion using the Planck model for the black body and the emission spectra of the atoms we can find the results for the peaks in the spectrum of stars is:
The general shape is that of a black body and the peaks are due to chemical compounds or elements in the star.

How to find force if mass time and distance is given?
Answer:
For example, speed is a length divided by time. Force is mass times acceleration, and is therefore a mass times a distance divided by the square of a time. We therefore say that [Force] = MLT−2.
