A gas undergoes two processes. In the first, the volume remains constant at 0.230m3 and the pressure increases from 3.00×105Pa to 5.50×105Pa . The second process is a compression to a volume of 9.00×10?2m3 at a constant pressure of 5.50×105Pa .
Find the total work done by the gas during both processes.
As a result of the friction between their surfaces, after a while, both disks spin at the similar angular speed. Determine the work done by the frictional torque.
Two blocks are placed in contact on a horizontal frictionless surface. The smaller box has less mass than the larger box. A force F is applied to the small box as shown so that the boxes accelerate to the right.
Besides the gravitational force, a 3.25-kg object is subjected to one other constant force. The object starts from rest and in 1.20 s experiences a displacement of (4.10 - 3.30) m, where the direction of is the upward vertical direction. find out ..
A bullet of mass 0.0022 kg initially moving at 503 m/s embeds itself in a large fixed piece of wood and travels 0.71 m before coming to rest. Assume that the acceleration of the bullet is constant.
An elastic cord is 65 cm long while a weight of 56 N hangs from it and is 82 cm long while a weight of 84 N hangs from it. What is the spring constant of this elastic cord.
Explain how much work does the spring do on the block if the spring is stretched from relaxed length by 15.1 mm as the block is moved?
What is magnitude of the unknown force
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.
An 7.80 ball, hanging from the ceiling by a light wire 105 long, is struck in an elastic collision by a 2.20 ball moving horizontally at 5.00 just before the collision. Find out the tension in the wire just after the collision.
Joe is 0.500 m from the right end and weighs 920-N. Given that the scaffold is in rotational and translational equilibrium, what are the forces on each cable.
A 0.15 kg ball is placed in a shallow wedge with an opening angle of 150.For each contact point between the wedge and ball, find out the force exerted on the ball. Assume the system is frictionless.
A concave mirror is of hemisphjerical shape with radius 40cm. A thin layer of unknown transparent liquid is poured into mirror. The mirror liquid forms a real image and another real image is formed by the mirror alone.
