True : yes there are planets in the universe without a parent star called
rogue planets.
False : most stars are not binary
What is rogue planets ?
planets which do not orbits the planetary system is known as roque planets. For example, pluto. Rogue planets can be smaller and bigger than jupiter too.
Free-floating planets or rogue planets without orbits around stars may also harbor life, some scientists believe. Due to the gravitational effects of giant planets within their system, these planets get kicked out of their system like any other planets formed around stars.
no most stars are not binary, binary which means two stars orbit around the common center and approximately only 40 binary stars have been found till not in our solar system.

Answer:
In a series circuit, how does the voltage supplied by the battery compare to the voltage on each load? The voltage of the battery is equal to the voltage of each load added together. ... The voltage across the two resistors must both have the same voltage of the battery.

Physics also deals with the basic principles that explain matter and energy, and may study aspects of atomic matter by following concepts derived from the most fundamental principles. Chemistry focuses on how substances interact with each other and with energy (for example heat and light).
Answer:

Answer:
(b) Net force causes change in motion.
Explanation:
There can be a motion even if there is no net force acting on an object.
It can be justified by giving an example:- when object is moving at constant speed then it has no net force and still is in motion.
If there is a net force acting, then the object will accelerate and this will cause change in motion.
The change in motion can be change in direction of motion, change in speed of motion.
For example when an object is moving in east direction if someone accelerate it this will result in change in motion or change in speed and after some time the net force is applies in the north direction then the object will move in the north direction which proves that the net force also causes change in direction.
