A wire carries a current of 9.0 A in a direction that makes an angle of 35.0° with the direction of a magnetic field of strength 0.200 T. Find the magnetic force on a 6.00 m length of the wire.
A person pulls on a 50kg desk with a 200 N force acting at a 30 degree angle above the horizontal. The desk does not budge.
A model car is propelled by a cylinder of carbon dioxide gas. The cylinder emits gas at a speed of 4.5 g/s with an exit speed of 80.0 m/s. The car has a mass of 400 g, including the CO2 cylinder. Starting from rest, what is the car's initial accel..
A jetliner is moving at a speed of 187 m/s. The vertical component of the plane's velocity is 44.5 m/s. find out the magnitude of the horizontal component of the plane's velocity.
What is the centripetal force that would be required to keep a 4.0 kg mass moving in a horizontal circle with a radius of 0.80 meters at a speed of 6.0 meters/second?
assuming the average person has a mass of 68kg? Do not avoid the weight of the logs. Assume the specific gravity of wood is 0.6.
what was (a) the negative charge in coulombs on one of them and (b) the positive charge in coulombs on the other.
If a car traveling at 62 km/h will skid 22 m as its brakes lock, how far will it skid if it is traveling at 120 km/h when its brakes lock.
Uniform rate of acceleration
A sled is pulled with a horizontal force of 20 N along a level trail, and the acceleration is found to be 0.35 m/s2. An extra mass m = 4.2 kg is placed on the sled. If the same force is just barely able to keep the sled moving, what is the coeffic..
When burned, 3.7 tons of coal releases the amount of energy that you use over the course of a year in the form of heat. How many tons of coal are required to provide you with your yearly energy use if you were to get that energy from a coal burnin..
In a region where there is an electric field, the electric forces do +8.00x 10^-19 J of work on an electron as it moves from point X to point Y.What is the potential difference, VY - VX, between point Y and point X?
the coefficient of static friction is 0.26. If you apply the minimum force needed to get the refrigerator to move, illustrate what will the acceleration then be?
