Does a fly move on a bus? As the bus starts its motion forward, only the bus moves and not the fly. So now the velocity of bus be v and fly be 0. The fly will relatively be pushed back, when actually it stays in the same position but the bus moves forward. What […]

How do you calculate fluid movement? 14.5 Fluid Dynamics Flow rate and velocity are related by Q = Av where A is the cross-sectional area of the flow and v is its average velocity. The equation of continuity states that for an incompressible fluid, the mass flowing into a pipe must equal the mass flowing

What is a movement of water in a particular direction? Ocean currents are the continuous flow of huge amount of water in a definite direction while the waves are the horizontal motion of water. Water moves ahead from one place to another through ocean currents while the water in the waves does not move, but

What is an example of a movable pulley Class 5? Some single movable pulley examples include: construction cranes, modern elevators, some weight lifting machines in the gym, the sails on the sailboats, and so on. What are the 3 types of pulleys? Answer: There are three types of pulleys, namely, fixed pulleys, movable pulleys, and

In what direction is the friction force exerted by the bed of the truck on the crate? However, friction between the crate and the bed of the truck acts in such a manner as to oppose this relative motion between truck and crate. Thus, the friction force acting on the crate will be in the

Can someone be as fast as flash? But running as fast as the Flash is impossible. Since the Flash is a fictional character, just like Hulk, Iron Man, to name a few, the creators of the character are not exactly physicists and don’t take into account all of the problems connected to such a superpower.

Why do I see a random flash of light? They are not caused by lights or anything else outside of your body. Most flashes happen when the vitreous gel inside the eye shrinks or changes, pulling on the retina (the light sensitive lining of the eye). Flashes of light can also happen if you’re hit

Why do boats move up and down? This motion is generated directly either by the water and wind motion, particularly lateral wave motion, exerting forces against the hull or by the ship’s own propulsion; or indirectly by the inertia of the ship while turning. How do boats move in water? A boat moves because something

Which of the following terms best describes the idea that it is important to meet present needs without? Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. When a machine operates like a human with respect to learning and decision making

How fast is a firework rocket? Ten inch shells can travel at up to 180mph. This is quicker than the highest wind speed ever recorded in the United Kingdom (173mph) and higher than the highest forecast winds on the slopes of Mount Everest (175mph). What is the launch speed of a firework? At a fireworks
