In 550-600 words, outline the different methods that astronomers use to calculate the distances to astronomical objects, from the closest to the farthest.
A stone with a mass of 0.800 is attached to one end of a string 0.700 long. The string will break if its tension exceeds 50.0 . The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed.Find
It takes 8.5 J of energy to move a 3 mC charge from one plate of a 9.0 microfarad capacitor to the other. How much is the charge on each plate?
Two cylindrical metal wires, A and B, are made of the same material and have the same mass. Wire A is twice as long as wire B. What's the ratio RA/RB?
Find the force (magnitude and direction) exerted on her by the bungee cord at an instant when her downward acceleration has a magnitude of 6.4 m/s2. Ignore the effects of air resistance. Take the upward direction as positive.
The amount of internal energy needed to raise the temperature of 0.25kg of water by 0.2C is 209.3J. How fast must a 0.25KG basebal travel in ortder for its kinetic energy to equal this internal energy?
A baseball is thrown at an angle of 25° relative to the ground at a speed of 23.0 m/s. If the ball was caught 42.0 m from the thrower, how long was it in the air? How high did the ball travel before being caught?
A soccer ball is kicked at a speed of 14 m/s at an angle of 9 degrees above the horizontal. (a) What are the horizontal and vertical components of the ball's velocity?
A 80-kg bobsled is pushed along a horizontal surface by two athletes. After the bobsled is pushed a distance of 3 m starting from rest, its speed is 5 m/s. Find the magnitude of the net force on the bobsled.
