Q1. A Federation star ship (2.0×10^6) uses its tractor beam to pull a shuttlecraft (2.20×10^4) aboard from a distance of 14km away. The tractor beam exerts a constant force of 40,000 N on the shuttlecraft. Both spacecraft are initially at rest. How far does star ship move as it pulls the shuttlecraft aboard?
Q2. A projectile is launched at some speed at an angle of 74 degrees and travels a range of 262 meters. The launch angle is after that changed, but the projectile is fired at the same speed as the original case and also travels the same range of 272 meters. Find the maximum vertical displacement at 74 degrees, (ymax1), and find out the maximum vertical displacement for the second angle (ymax2), and then find out the difference between them in meters (diff = ymax1 - ymax2).
An object with a net charge of 44 µC is placed in a uniform electric ?eld of 554 N/C, directed vertically. The acceleration of gravity is 9.81 m/s^2. What is the mass of this object if it ?oats in this electric ?eld?
Every day our Earth receives 1.55×1022 J energy from the Sun. If we were able to use 0.85 percent of this energy to accelerate spaceships, then how various missions will be possible in one year.
A point charge q1 = -8.9 μC is located at the center of the thick conducting shell of inner radius a = 2.2 cm and outer radius b = 4.5 cm, the conducting shell has a net charge of q2 = 1.1 μC.
Drawing on Erastothenes' method, if two observers are due north and south of each other and are separated by 490 km, what is the circumference of their spherical world if they see the same star on their meridian at altitudes of 29 degrees and 45 degr..
A steel ball of mass M is released from rest at point P. It follows a smooth curved rail to point Q and finally reaches point R with K.E. of 7J. The speed of the ball at point Q is 2MS-1 and the height between point P and the ground is 3m. Then find ..
A crate of 31.9- tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 345. After that you must reduce your push to 247 to keep it moving at a..
Find out (a) capacitance and (b) maximum voltage that can be applied to a Teflon-filled parallel- plate capacitor having a plate area of 175 cm2 and an insulation thickness of 0.040 mm.
A 120 g trick baseball is thrown at 51 km/h. It explodes in flight into two pieces, with a 50 g piece regular straight ahead at 86 km/h. How much energy do the pieces gain in the explosion.
An iron bolt of mass 63.4 g hangs from a string 32.6 cm long. The top end of the string is fixed. Without touching it, the magnet attracts the bolt so that it remains stationary, displaced horizontally 28.5 cm to the right from the before vertical li..

Galaxies form by gravitational collapse of regions that are denser than average. Noting that the present day average mass density of the universe is ρ = 3 × 10-30 g/cm-3, estimate how long it takes for a galaxy to collapse.
Eight identical, non-interacting particles are placed in a cubical box of sides L = 0.2 nm. Find the lowest energy of the system (in electron volts) and list the quantum numbers of all occupied states if (a) particles are electrons and (b) particles..
