To find the time taken by a particle projected vertically upwards to reach its highest point, we can use the following steps: 1. Identify the Initial Velocity (u): The particle is projected with an initial velocity of u=10m/s. 2. Understand the Acceleration due to Gravity (g): When...
85 mA particle is projected vertically upwards from the top of tower with velocity 10 m/s. It reaches the ground in 5 s. find Average speed & average velocity of particle.
However, the particles are often transported upwards in the atmosphere, and at higher altitudes atmospheric heating reduces the boundary layer lapse rate, resulting in a shallower PBL. Thus, under such conditions a feedback loop is initiated where more absorbing aerosols cause reduced turbulence, a ...
At time t = 0, a particle of mass m is projected vertically upwards with speed U.The particle is subject to air resistance of magnitude, where v is the speed of the particle at time t and k is a positive constant.Show that the particle reaches its greatest height, H, above the point...
6. A small object P, of mass m, is projected vertically upwards from the ground with speed U. As P moves upwards it picks up droplets of moisture from the atmosphere. The droplets are at rest immediately before they are picked up. In a model of the motion, P is modelled as a parti...
Strong collective coupling to the cavityNC ≫ 1 is the key requirement for both approaches to generate entanglement, whereCis the single particle cooperativity parameter43,47,48. Previously, an interferometer was operated in a low finesse cavity49,50, to provide power build-up, spatial mode...
A (1.61 ± 0.04) × 1010 N m–2 B (1.61 ± 0.05) × 1010 N m–2 C (1.61 ± 0.07) × 1010 N m–2 D (1.61 ± 0.09) × 1010 N m–2 6 A rock on the surface of Mars is projected vertically upwards with an initial speed of 9.4 m s–1 . The rock rises to a height ...
We created the trap by directing a 532 nm continuous wave laser beam (LaserQuantum gem532) vertically upwards and focusing it with a 100 mm plano-convex lens. The long focal distance produced a weak optical trap. The laser beam had a diameter of 0.9 mm, resulting in a numerical aperture ...
