(1) A block whose weight is 41.0 N rests on a horizontal table. A horizontal force of 36 N is applied to the block. The coefficients of static and kinetic friction are 0.650 and 0.420, respectively. Will the block move under the influence of the force, and, if so, what will be the block's acceleration? (If not, enter 0.)
An airtight box has a removable lid of area 1.10 multiplied by 10-2m2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.80 multiplied by 105 Pa.
An atomic nucleus of mass m travelling with speed v collides elastically with a target particle of mass 2.000m (at first at rest) and is scattered at 90.
The coefficient of static friction between the ladder and the ground is 0.55, and the ladder makes a 50.0° angle with the ground. Explain how far up the ladder can an 720 N person climb before the ladder begins to slip?
A space vehicle is coasting at a constant velocity of 23.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.395 m/s2 in the +x directio..
Two positive point charges, each 17? C, lie along the x-axis at x = –0.12m and x = +0.12m.
A space station, in the form of a wheel 133 m in diameter, rotates to provide an "artificial gravity" of 2.20 m/s2 for persons who walk around on the inner wall of the outer rim. Find the rate of the wheel's rotation in revolutions per minute that wi..
An electric scooter has a battery capable of supplying 140 Wh of energy. If friction forces and other losses account for 60.0 percent of the energy usage, what altitude change can a rider achieve when driving in hilly terrain, if the rider and scoote..
A string of mass 0.0003kg/m and 0.5m long is vibrating 200 cycles per second. What must be the tension? What hanging mass would generate this tension? I got 12N for tension. Is this correct? And how would you solve for hanging mass.
Tarzan swings through the jungle by hanging from a vine. Immediately after he steps off the branch, is Tarzan's acceleration zero or nonzero
A copper vat is 12 m long at room temperature (20 degrees Celsius). How much longer is it as it contains boiling water at 1 atm pressure.
Young's Double Slit Experiment is performed with 589 nm light and a distance of 2.00 m between the slits and the screen. The fifth interference minimum is observed 7.50 mm from the central maximum. Resolve the spacing of the slits.
A wrecking yard inventor wants to pick up cars by charging a 0.400 m diameter ball and inducing an equal and opposite charge on the car. If a car has a 1000 kg mass and the ball is to be able to lift it from a distance of 1.00 m: (a) What minimum ..
