Are kinematics easy? Is kinematics tough (G) This is not a tough chapter, though some of the concepts especially differentiation, integration, vectors. relative motion, and acceleration of particle in uniform circular motion would feel new. How many types of graphs are drawn in kinematics? There are three main kinematics graphs: displacement-time graphs, velocity-time graphs, and … Read more
The linear momentum of a system of particles is equal to the product of the total mass M of the system and the velocity of the center of mass. How do you find the center of mass problem in physics? The center of mass can be calculated by taking the masses you are trying to … Read more
If the bottle is in the inverted position, the air has nowhere to go and it will oppose the water. It is not always true that the water does not get inside the bottle in an inverted position. If the water pressure is greater from underneath, it will compress the inside air as we push … Read more
What is coulomb’s law PDF? Coulomb’s Law gives the force of attraction or repulsion between two point charges. If. two point charges q1 and q2 are separated by a distance r then the magnitude of the force of. repulsion or attraction between them is. F = k|q. What is coulomb’s law class 12 formula? Coulomb’s … Read more
Why do you feel heavier or lighter when riding in an elevator? If you stand on a scale in an elevator accelerating upward, you feel heavier because the elevator’s floor presses harder on your feet, and the scale will show a higher reading than when the elevator is at rest. What is the apparent weight … Read more
How do you find the amplitude of a wave in physics? How do you find the period of a wave in physics? The formula for period is T = 1 / f , where “T” is period – the time it takes for one cycle to complete, and “f” is frequency. To get period from … Read more
How do you find the angular acceleration of a merry-go-round? What is the problem of merry-go-round? The merry-go-round is spinning. Therefore, it is a rotational motion problem. How do you find the angular velocity of a rotating object? v = ω × r . We can rewrite this expression to obtain the equation of angular … Read more
The parachute is deployed using either a 15 or 20 feet (4.6 or 6.1 m) static line, allowing the parachutist to be delivered by either C-130 or C-17 aircraft. The T-10D main parachute is a parabolic-shape and has a nominal diameter of 35 feet (11 m) with 30 suspension lines. Does size matter parachute experiment? … Read more
What is the relationship between fluid pressure and fluid density? When pressure increases, density increases. When the pressure decreases, density decreases. What is the density of a fluid whose pressure increases at the rate of 100 KPA for every 5.6 m of depth? =1.7×103Kg/m3. How do you find the volume given the density and pressure? … Read more
How do you find the amplitude of a wave in physics? What is the formula for calculating amplitude? The amplitude of a wave is the maximum displacement of the particle of the medium from its equilibrium position. It is represented by A. The Amplitude formula can be written as. y = A s i n … Read more
