physics questions and solutions


What is an asteroid, comet, dwarf planet with respect to their mass, moment of inertia and dimension? The other wire is vertical with the current directed upward. Services, Non-exact solutions in general relativity, Working Scholars® Bringing Tuition-Free College to the Community.

Determine the final temperature of the water and the work required, in kJ/kg, for this compression. A monatomic ideal gas that is initially at a pressure of 1.40 x 10^5 Pa and with a volume of 0.0780 m^3 is compressed adiabatically to a volume of 0.0400 m^3. Heat is added to the water until the volume of the water has increased by a factor of 2000.

Imagine two wires oriented perpendicular to each other and almost touching. = 20 ? Download the free PDF of JEE Main Physics Important Questions from the link given below. What is the big idea of Physical science? When we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters.

Light that is polarized along the vertical direction is incident on a sheet of polarizing material.

1.

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity E=230 GPa and Poisson's ratio \... A beam of polarized light has an average intensity of 19 W/m^{2} and is sent through a polarizer.

A third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis... One mole of nitrogen gas in a rigid container of volume 20 liters is heated from an initial pressure of 1 bar to a final pressure of 3 bar. Is it possible in theory to cut an object in half until it ceases to exist? The organist faces the south wall, sitting 0.800 m away from it. When the angle of incidence is 60.0 degrees, the reflected light is completely polarized parallel to the surface of the glass. Explain. In a church choir loft, two parallel walls are 5.30 m apart. Is there any website to download the solutions? What is the transducer in a smoke detector? A load of 250 lb is carried at the middle of the rope. The incident angle is 52 degrees and the refracted angle is 25 degrees. Give any two salient points addressed by Feynman. in the figure, a light ray is air is incident in a flat layer of material 2 that has an index of refraction n2=3.0. A 590 nm light beam in air hits the flat surface of a certain liquid, and the beam is split into a reflected ray and a refracted ray. b) Fats . The tension is 70 N. An oscillator at one end sends a harmonic wave with an amplitude of 1.00 cm down the rope. The rake angle in an orthogonal cutting operation = 12 Deg. When did Stephen Hawking write A Brief History of Time? F and 13 psia to a final pressure of 80 psia. Our experts will gladly share their knowledge and help you with programming homework. Determine the acceleration of points A and B of the chain, knowing that T_A = 14 \ N a... A chain of length l and mass m lies in a pile on the floor. An ideal gas expands isothermally, performing 5.57 x 10^3 J of work in the process. The critical shaft fillet is 70 mm from B. In the figure, a conducting rod of length L = 27.0 cm moves in a magnetic field B? If 2 moles of CO_2 at 2L and 500K are expanded reversibly to 20L, more work can be obtained from an adiabatic process than from an isothermal process.

The ammonia is compressed to a pressure of 5.5 bar. When she arrives at the bottom of the ramp her speed is 6.78 m/s. A gymnast lands at the center of this beam with a 1.5 kN force. How much work is done on the gas?
of magnitude 0.360 T directed into the plane of the figure. in joules. There is a uniform magnetic field of 0.6 T pointing upward. Which book or which company's study material is the best for clearing concepts in mechanics?

Consider such a painting with the dots in... One mole of an ideal gas initially at a temperature of Ti = 2.0 degrees C undergoes an expansion at a constant pressure of 1.00 atm to eight times its original volume.
