Which planet's orbit was Kepler first studying when he began to develop his laws of orbital motion? A Earth B Mars C Saturn D Jupiter
The planet orbit Kepler was studying when he developed the law of orbital motion is Mars.
What is law of orbital motion?
Kepler’s law of orbital motion are three laws and can be stated as follows;
All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time. The squares of the sidereal periods of revolution of the planets are directly proportional to the cubes of their mean distances from the Sun.The first and second Kepler's law of orbital motion was proposed when Kepler discovered that the orbit of Mars was an ellipse.
Thus, the planet's orbit that Kepler was first studying when he began to develop his laws of orbital motion is Mars.
The correction that describes the planets orbit Kepler was studying is Mars.

Answer:
children spend much time watching adults in our world. children should be protected from all violent scenes
Explanation:
Are acts of violence and aggression taught behaviours? Albert Bandura and his colleagues established one method that kids pick up violence in the well-known and significant "Bobo doll experiment."
According to Bandura's social learning theory, learning happens through interactions with other people and observations of the world around us. In essence, people pick up new skills by observing others and then copying their behaviour.

Yes, all violent scenes should be kept out of children. This experiment is also known as the Bobo Doll Experiment from the perspective of Albert Bandura. Which Discloses Aggression Among Children.
Numerous social evils, such as war and intergroup violence, are caused by aggression. It should come as no surprise that the topic is one of psychology's most researched areas. Most of the research on human aggression has been conducted by researchers in the discipline of social psychology, which is devoted to the study of interpersonal communication and group dynamics.

what is true about current that flows through resistors in parallel? all current flows through the lowest value resistor(s). all current flows through the highest value resistor(s). the current is determined by v
A resistor is a passive two-terminal electrical component used in circuits to implement electrical resistance. Resistor use in electronic circuits includes lowering current flow, adjusting signal levels, dividing voltages, influencing active devices, and terminating transmission lines.
The voltage drop across a resistor increases with resistor size and consumes more energy as a result. Voltage drop can be confirmed using Ohm's Law. Voltage in a DC circuit is equal to current times resistance.
V = I R.
Resistors are said to as being in parallel when two nodes share terminal connections. The lowest parallel resistor is larger than the comparable overall resistance.
The supply current is equal to the total of the currents flowing through all of the resistors when they are linked in parallel. The supply current is equal to the sum of the currents in a parallel circuit's branches. The potential difference across parallel connections of resistors is the same.

difference between friction and collision
Friction frequently has no immediate relevance. Perpendicular interactions are collisions. One parallel force is friction.
Consider a billiard ball colliding with another ball on a pool table. Although the billiard ball may enter at an angle, the momentum transfer occurs perpendicular to the contact plane.
Does collision cause friction?The internal force (of the collision) is often larger than the exterior force (friction) on a system when there is a collision within that system.
Two objects meet in an elastic collision when no kinetic energy is wasted. The kinetic momentum and energy of the objects are preserved when they bounce back from one another. We are dealing with an impactor because inelastic collisions are thought to happen when the two items stay together after the impact.

Is there static friction on anything that is not moving?
Or, is there static friction present ONLY when there is something trying to get something else to move, but it not moving?
The friction force is static since there is no relative motion between the shoe and the ground. The friction force, if any, is the static force of friction if there is no relative motion between the objects in contact (FS). An illustration would be a box that sits motionless on a ramp.
What is static friction?A force that holds an object at rest is called static friction. The following is a definition of static friction:
the resistance people feel when they try to move something that is stationary on a surface without actually moving their bodies or the surface they are trying to move it on.
It can be explained as the frictional force that perfectly balances the applied force throughout the body's stationary state.
The static frictional force is self-regulating, meaning that it will always be equal to and the opposite of the applied force.
Friction is the force that prevents an object from moving in the direction it is sliding along a surface, therefore it acts in the opposite direction. But a friction force can be felt even when an object is not moving.

If the displacement of a person from their desk is 25.92 m if 27 m, 17° S of W, they are west from desk.
Resolving the 27 m distance into its horizontal and vertical components. The horizontal component will describe how far west they are and the vertical component will describe how far south they are. After resolving the components make a right angled triangle.
cos θ = Adjacent side / Hypotenuse
θ = 17°
Adjacent side = Horizontal component
Hypotenuse = 27 m
cos 17° = West distance / 27
West distance = 0.96 * 27
West distance = 25.92 m
In a right angled triangle some of the ratios similar to the one used above can be used. These ratios are called as trigonometric ratios. These ratios use trigonometric functions and relate them to sides of a right angled triangle.

Thomas Young did experiments with light, known as the double-slit experiments, to produce interference patterns that could only be explained by evoking a wave-like nature for light.
Before the nineteenth century, the wave-like properties of light were not known. They got to know that light behaved like a wave thanks to Thomas Young's double slit experiment which he performed in the early 1800s.
Thomas Young made use of a light source (probably sunlight), barriers with one or two slits, and a screen for observation. First, he allowed light to pass through a slit in the barrier. Due to diffraction, the light that passed through the slit spread out into wave fronts, with the slit becoming the new light source. Another barrier with two slits was then put after the first one, just at the right distance, As expected the light from the first barrier passed through the two slits on the second barrier. The observation screen was placed after the second barrier.
There were two possible results from this experiment. One was that the sum of the intensity of light from each slit will give the intensity of both slits. In this case, light would be a particle. The second possible result was that dark and light bands will be created on the observation screen due to the interference patterns made by the superposition of light. In this case, light would be a wave.
At the end of the experiment, interference patterns were observed on the screen, which showed that light travelled in waves. Hence, Thomas Young's double slit experiment showed the wave-like nature of light.

Two-level systems, or systems that effectively have just two energy levels, are an important class of systems because at sufficiently low temperatures, just the two lowest energy levels will be active. Solids are particularly significant because they contain two different energy levels for each atom, depending on whether the electron is spinning up or down.
