Calculate the terminal velocity of a 1.0 cm bug. Assume that the density of the bug is 1.0 g/cm^3.and the bug is spherical in shape with a diameter of 1.0 cm. Assume further that the area of the bug subject to air friction is πr^2.(the coefficient of air friction is 0.88).
IF the bug falls from a height of 200 m find the speed with which the bug hits the ground if there is no air resistance.
A force vector has a magnitude of 577 newtons and points at an angle 43o of below the positive x axis. What is (a) x scalar component and (b) y scalar component of the vector.
Ice at -14.9 °C and steam at 115 °C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 52.0 °C is present.
The threshold intensity for a human eye to sense the presence of light is 50 photons falling on the retina within a period of 0.1 s. Estimate how far away the star can be away
The figure below shows a thin-lens representation of a compound microscope (not to scale). The objective produces a real image I of object O just inside the focal point F1 of the eyepiece. Image I then acts as an object for the eyepiece, which pro..
A peregrine falcon dives at a pigeon. The falcon starts with zero downward velocity and dives with the free-fall acceleration. If the pigeon is 81.5 m below the initial height of the falcon, how long does it take the falcon to intercept the pigeon..
