sin 36.9=0.60042
sin 53.1=0.79968
cos 36.9=0.79968
cos53.1=0.60042
you would have to study taylors or maclaurin series to find these values which you will study in higher education like btech 1st year.

As per Newton's third law of motion -For every action there is an equal and opposite reaction so action force is force acting in one direction. Reaction force is force acting in the opposite direction. Angle between them is 180 degrees as these forces work in a straight line and opposite directions.

no, it doesnt cancels each other beacuse both action and reaction are applied on different bodies. two foces can cancels each other only if they are equal and opposite in direction and acting on a single body. If you place your foot on a boat then you apply force on the boat and due to newtons third law the boat also applies same and opposite force on you. here the two forces are same and opposite but not acting on a single body so that these doesnt cancel out each other.

- Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance.
- Absolute zero is the point at which the fundamental particles of nature have minimal vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion.
- By international agreement, absolute zero is defined as precisely; 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale; and –273.15 degrees Celsius on the Celsius scale.
- Absolute zero is also precisely equivalent to; 0 degrees R on the Rankine scale (also a thermodynamic temperature scale); and –459.67 degrees F on the Fahrenheit scale.
- While scientists can not fully achieve a state of “zero” heat energy in a substance, they have made great advancements in achieving temperatures ever closer to absolute zero (where matter exhibits odd quantum effects).
- In 1994, the NIST achieved a record cold temperature of 700 nK (billionths of a kelvin).
- In 2003, researchers at MIT eclipsed this with a new record of 450 pK (0.45 nK).
Therefore, absolute zero corresponds to the level of zero energy.

At absolute zero, all motion comes to a standstill. A lower temperature is not feasible because there is no velocity smaller than zero and no energy content less than nothing. Energy in this instance means only the energy that can be taken away from the particles and does not include the rest mass or quantum mechanical zero-point energies for confined particles.That's why it corresponds to zero energy. Absolute zero corresponds to –273 degrees Celsius and –460 degrees Fahrenheit.
Temperature: it is a measure of the energy content of matter. When air is hot, the molecules move fast and they have high kinetic energy. The colder the molecules are, the smaller their velocities are and, subsequently, their energy.

the above statement isnt correct. i would like to clarify this:
Bernoulli theorem states that the total energy(sum of kinetic+pressure+potential energy) associated at a particular point is constant.

A polar orbiting satellite closely parallels the earth's meridian lines, thus having a highly inclined orbit close to 90°. It passes over the north and south poles each revolution. As the earth rotates to the east beneath the satellite, each pass monitors an area to the west of the previous pass at intervals of roughly 90 to 100 minutes. These strips can be pieced together to produce a picture of a larger area.
Uses: monitoring the weather, observing the Earth’s surface, military uses including spying.

A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers directly over the equator, that revolves in the same direction the earth rotates (west to east).
Uses: Direct broadcast TV, Communication network, Defense and intelligence, global positioning or GPS - which is used for satellite navigation systems
