Palmer hikes to a campsite where he will spend the evening. He hikes 6.0 km, north and 3.0 km, west. The magnitude of Palmer’s displacement is ___km.
A block weighing 100 N and having dimensions 200 mm on an edge is
allowed to slide down an incline on a film of oil having a thickness of 0.05 mm.
If a linear velocity profile in the oil is assumed, what is the terminal
speed of the block?
The viscosity of the oil is 7*10^-2 Ns/m^2
You and your friends are playing in the swimming pool with a 25-in diameter beach ball. How much force (in Newtons) would be needed to push the ball completely under water?
Palmer hikes to a campsite where he will spend the evening. He hikes 6.0 km, north and 3.0 km, west. The magnitude of Palmer’s displacement is ___km.
A 40-kilogram mass is moving across a horizontal surface at 5.0 m/s. What is the magnitude of the net force required to bring the mass to a stop in 8.0 seconds?
Can 500 year old rope survive under fresh water intact
A close look at the diagram below shows graphite (or sometimes water) is used as a moderator to slow neutrons, reference the Periodic table to identify what two metals are used to absorb neutrons. *
How much work is done on a bookshelf being pulled with a force of 53.8 N for a distance of 5.00 m at an angle of 37.0o from the horizontal?
When you load a heavy box into a big moving truck, it is often easier to push it up a sloped frictionless ramp to the back of the truck than to lift it directly up into the truck. Yet, the change in the gravitational potential energy of the box is the same no matter how you get it from the ground into the moving truck.
Compare the amount of work you must do to lift the box directly into the truck with the amount of work you need to push the box up the frictionless ramp.
A typical capacitor in a memory cell have a capacitance of 3 x 10-14 F. If the voltage across the capacitor is 0.5 V, what is the number of electrons that must move to the capacitor to charge it?
