mol
(b) How many molecules are in the vessel?
molecules
An object with a net charge of 44 µC is placed in a uniform electric ?eld of 554 N/C, directed vertically. The acceleration of gravity is 9.81 m/s^2. What is the mass of this object if it ?oats in this electric ?eld?
How numerous extra electrons are on this particular oil drop (given the presently known charge of the electron)?
What is the Reynolds number for the fastest falling ball in the experiment. Use the same data as in problem 1, glycerin density of 1.30 g/cm^3
A small but measurable current of 7.4 x 10-10 A exists in a copper wire whose diameter is 2.9 mm, calculate the current density and electron drift speed
When catching a baseball, a catcher's glove moves by 12cm along the line of motion of the ball. If the baseball exerts a force of 477N on the glove, how much work is done by the ball.
The two hot-air balloons in the drawing are 48.2 m and 61.0 m above the ground. A person in the left balloon observes that the right balloon is 13.3° above the horizontal.
A stone is thrown upward with an initial velocity of 6 m/s. What maximum height will the stone reach?
As a bat flies toward a wall at a speed of5.70m/s , What frequency does the bat hear in the reflected wave
The coefficients of friction between a block of mass 1.0 kg and a surface are ?s = 0.75 and ?k = 0.40. What is the magnitude of the frictional force
A rifle with a barrel length of 62 cm fires a 12 g bullet with a horizontal speed of 460 m/s/s. The bullet strikes a block of wood and penetrates to a depth of 15 cm.
When subject to a steady acceleration of 0.800 g, the object must be located 0.600cm from its equilibrium position. Find the force constant required for the spring.
The moment of inertia of a uniform ring is I (r) = M (r) * R^2 (r), where M (r) and R (r) denote the mass and radius of the ring. Compute the moment of inertia of this disk
