Q. The head of a rattlesnake can accelerate at 50.0 m/s^2 in striking a victim. If a car could have the same acceleration, how long would it take for it to reach a speed of 100.0 km/h from rest?
Q. A charge of -4.00 nC and a charge of -5.40 nC are separated by a distance of 70.0 cm. Find the position at which a third charge of +7.60 nC can be placed so that the net electrostatic force on it is zero.
Falls resulting in hip fractures are a major cause of injury and even death to the elderly. Typically, hip's speed at impact is about 2. If this can be reduced to 1.30 or less, hip will usually not fracture. One way to do this is by wearing elasti..
Determine the angular acceleration of the pulleys and the tension T in the cord supporting the 612 Kg mass when it is released from rest.
Outline what you know about Plasmonics? Outline what you know about Raman spectroscopy and surface enhanced Raman spectroscopy?
What is a stopping distance
Two long thin parallel wires 13.0 cm apart carry 32 A currents in the same direction. Determine the magnetic field at point P, 12.0 cm from one wire and 5.0 cm from the other.
Assume air resistance is negligible; from what height (in cm) above the compressed spring was the block dropped.
A 43kg block of ice slides down the frictionless incline 1.50m long and 0.82m high. A worker pushes up against the ice, parallel to the incline, so that the block slides down at constant speed.
How greatly time elapses before the compass hits the ground
A 70.0 kg circus performer slides 4.90m down a pole to the circus floor, starting from rest. What is the kinetic energy of the performer as she reaches the floor if the frictional force on her from the pole (a) is negligible (she will be hurt) and (b..
The light energy that falls on a square meter of ground over the course of a typical sunny day is about 20 MJ. The average rate of electric energy consumption in one house is 1.0 kW. Find the energy consumption and area required by the solar cell
For this experiment you will require a stand, string, a paper or plastic cup, a nail, a roll of paper towels or similar sized paper, coloured sand, or some other dry powdery product, and a ruler or measuring tape.
An aging coyote cannot run fast enough to catch a roadrunner. He purchases on eBay a set of jet-powered roller skates, which provide a constant horizontal acceleration of 15.0 m/s2. The coyote starts at rest 70.0 m from the edge of a cliff at the ins..
