b) Calculate (i) the internal energy,
(ii) the work done on the gas and
(iii) the heat transfer
If you were to send a beam of laser light to a space station above an atmosphere and just above the horizon, would you aim the laser above, below or at the visible space station.
An electron is accelerated by a uniform electric field (1000 V/m) pointing vertically upward. Utilize newton's laws to determine the electron's velocity after it moves .10 cm.
Suppose a car starts from rest and completes a straight line, 1/4 mile (402 meter) race in 12.3 seconds. Assume the acceleration to be constant.
Assume that ABC has no Section 751(c) or 751(d) assets and ignore the accrual of interest on the partnership mortgage liability. If A accepts D’s offer, illustrate what is the amount and character of A’s gain or loss?
(a) How many times does PSR 1937+21 rotate in 77.0 days? (b) How much time (in s) does the pulsar take to rotate 5.00 × 106 times and (c) what is the associated uncertainty, in s?
Two point charges are separated by 6 cm. THe attractive force between them is 20N. What is force between them when they are separated by 9 cm? What is the equation used to arrive at this reply?
If a ball is thrown upwards at 20 ft/sec, the height h after t seconds is given by h = -16t^2 + 20t. How many seconds does it take for the ball to reach its greatest height, and what is this height.
if the barge can only be pushed 20-cm deeper into the water before water overflows to sink it, how various 400-kg horses can it carry.
express what would be the frequency of vibrations.
Why does a shirt or blouse taken from a clothes dryer sometimes cling to your body?
Two carts with masses of 10.60 kg and 2.50 kg, respectively, move in opposite directions on a frictionless horizontal track with speeds of 6.70 m/s and 3.50 m/s, in that order. The carts stick together after colliding head-on. Find the final speed of..
Find the resistance between points A and B. A car starts from rest on a curve with a radius of 130 m and accelerates at 0.500 m/s^2. How many revolutions will the car have gone through as the magnitude of its total acceleration is 2.50 m/s^2.
