If the coefficient of static friction is less than that found above, and if the coefficient of kinetic friction between the block and the table is .05, find the time it takes for the 6kg mass to fall 7m to the floor if the system starts from rest.
Two shuffleboard disks of equal mass, one orange and the other yellow, are involved in an elastic, glancing collision. the yellow disk is initially at rest and is struck by the orange disk moving with a speed of 5.40 m/s. after the collision, the orange disk moves along a direction that makes an angle of […]
Cobwebs are popular decorations at Halloween time, but an experiment in which spiders were given psychoactive substances showed that it really affects their web spinning skills! The web below was spun under the influence of what?
If hubble’s constant is actually half the value we believe it to be (70 km/(s mpc)), the universe would be
A soccer player extends her lower leg in a kicking motion by exerting a force with the muscle above the knee in the front of her leg. she produces an angular acceleration of 27.5 rad/s2 and her lower leg has a moment of inertia of 0.750 kg · m2. what is the force exerted by […]
(a) find the potential at point p. (q = 2.5 x 10-9c, a = 50 cm) (b) how much work by an external force is required to move a charge of – 3 µc to point p. (c) if the particle (mass = 5.0 µg) were released from rest at point p, what would be […]
What is the single most important parameter in determine the material removal rate in a machining process?
True or false the light that is emitted from a semiconductor, upon external stimulation, is longer and longer in wavelength as the particle size of the semiconductor decreases.
Consider three capacitors c1, c2, and c3 and a battery. if only c1 is connected to the battery, the charge on c1 is 32.2 µc. now c1 is disconnected, discharged, and connected in series with c2. when the series combination of c2 and c1 is connected across the battery, the charge on c1 is 23.4 […]
A charge per unit length given by l(x) = bx, where b = 12 nc/m2, is distributed along the x axis from x = +9.0 cm to x = +16 cm. if the electric potential at infinity is taken to be zero, what is the electric potential at the point p on the y axis […]
