Q. An airplane needs to reach the velocity of 367 km/h to take off. On a 2000 m runway, what is the minimum acceleration necessary for the plane to take flight?
Q. What force (magnitude) does the spring exert on the object while it is a distance 2.90×10-2 below equilibrium position, moving upward?
A uniform solid disk with a mass of 23.8 kg and a radius of 0.712 m is free to rotate about a frictionless axle. Forces of 92.0 and 124 N are applied to the disk. Taking the clockwise direction to be the negative direction, what is (a) net torque pro..
What power is dissipated in a single light. A proton is fixed in place. An electron is released from rest and allowed to collide with the proton. Then the roles of the proton and electron are interchanged, and same experiment is repeated. Which is ..
An object has a kinetic energy of 313 J and the momentum of magnitude 24.1 kg·m/s. Find out the speed and the mass of the object.
find the final temperature when 1000 g of water at 20 celcius in a 125 g copper calorimeter is mixed with 50g of steam originally at 153 celcius.
Find the distance from the positive plate
After being accelerated to a speed of 1.26×105 m/s, the particle enters a uniform magnetic field of strength 2.00 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen). The results of this experiment allow one..
A diffraction grating with 395 lines/mm is 1.00 m in front of a screen. What is the wavelength of light whose first-order maxima will be 16.9 cm from the central maximum on the screen.
Earth's atmosphere, the electric field above Earth's surface has been measured to be 150 N/C downward at an altitude of 250 m and 165 N/C downward at the altitude of 400 m. compute the volume charge density of the atmosphere.
find the non-zero Christoffel symbols and the equations, of the geodesic, for the two dimensional case of move-ment on the surface of a cylinder of radius and show that the transformation is an invariance transformation by finding the function A
Two carts with masses of 5.00 kg and 2.64 kg move toward each other on a frictionless track with speeds of 4.86 m/s and 3.46 m/s correspondingly. The carts stick together after colliding head-on. Find the final speed.
Find out the least compression of the spring
