If the two stage rocket of a weights 100 kg and 10 kg separately and contains 800 kg and 90 kg fuel
separately, what is the final velocity that can be achieved with an exhaust velocity of 1.5 km/sec. (Given
log10 =2.3 and log102 =0.3 )
Find the moment of inertia of a circular disc (i) about an axis through its center and perpendicular
to its plane (ii) about a diameter.
Write a Java program to print "hello" on the screen and write your name on the separate line?
4.) Two parallel wires are separated by a distance of 0.05 m. Wire 1 carries a carries current of 12.0 A. Wire 2 carries a current of 6.0 A flowing in the opposite direction as shown in the illustration. Find the (a) magnitude and direction of the magnetic field created by wire 1 at wire 2, (b) force exerted by wire 1 on the 2.0 m long section of wire 2, and (c) force exerted by wire 2 on wire 1.
5.) What should be the length of an ideal solenoid consisting of 1250 turns for the magnetic field in its interior to be 0.025 T? A current of 2.0 A is flowing through the solenoid.
1.) A proton moves through a uniform magnetic field of magnitude 2.0 µT=2.0 x 10^6 T at a speed of 5.00 x 10^6 m/s. (a) What is the magnitude of maximum magnetic force it can experience?
(b) If the proton is replaced by an electron, will it experience the same maximum force?
2.) A 55.0 m wire carries a current of 2.25 A in a location where Earth's magnetic field is 4.5 x 10^3 T. The wire experiences a force of 0.15 N. Find the angle between the wire and the magnetic field.
3.) A long straight wire carries a current of 1.0 A.
(a) At what distance from the wire is the magnitude of the magnetic field equal to 2.5 x 10^-5 T?
(b) What is the magnitude of the magnetic force that this wire will exert on a 3.0 nC particle moving at 4.2 x 10^4 m/s perpendicular to the field at that distance?
What is the percentage of common variance between variables if the correlation
coefficient is -0,7?
1. 70%
2. 4,9%
3. -49%
4. 49%
5. Explain the distinction made in economic analysis between the short run and the
long run.
4. “If it were not for the law of diminishing returns, a firm’s average cost and average variable
cost would not increase in the short run.” Do you agree with this statement? Explain.
One day while Cody was playing with his friends in the woods, they stumbled upon a bearded old man living alone in his cabin. Cody and his friends were shocked that somebody could grow that old. Cody, refusing to believe that it is possible, asked the old man his age. The old man said, "My age is the sum of The Programmer and your teacher's ages subtracted by the age of your friend, Peter". Puzzled with this statement, Cody quickly tried to input the ages of The Programmer, his teacher, and his friend, Peter. Help Cody find out the age of the old man.
Cody was amazed that people could grow so old and wondered If he, a robot, would also be able to grow like that. Suddenly, he heard a sharp cry nearby, and as he tumed the comer, he saw a baby. Cody never saw a baby before, plus, he was never a baby himself so he was really surprised that something could be that young. Cody asked the baby his age and the baby replied through crying, "My age is the product of The Programmer's age and your teacher's age all of which is divided by Peter's age then added by 1 Cody quickly inputted all the ages.
