If the fuel he carries produces 36 kJ of heat per gram when it burns, how much fuel should he carry? (For the sake of simplicity, assume that the transfer of heat is 100 %% efficient.)

Pressue is related to momentum

You discover a binary star system in which one member is a 15 solar mass main-sequence star and the other star is a 10 solar mass giant star. Why should you be surprised, at least at first

If a star's parallax angle is too small to measure, what can you conclude about the star's distance from the Earth?

A 55-kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.30, and the coefficient of kinetic friction is 0.20.

An object has a velocity of 10m/s south. in what direction is its momentum

Use the data from the table to calculate the average rate of change of martian temperature t with respect to time t over the interval from 8:07 am to 9:34 am. (round your answer to three decimal places.)

Determine el valor de la potencia electrica que experimente un circuito cual se somete a 120 voltios emitidos por accion de las cargas electricas que viajan a través de el y que experimentan 4 amperios de intensidad, durante todo el trayecto del

Some wave characteristics depend upon how the wave is produced. other wave characteristics depend upon the properties of the medium.

What is the mass of oxygen in an oxygen tank at 20 C if the tank has a volume of 0.20 m3 and the oxygen pressure in the tank is 4.0 105 N/m2 (mass of one mole of one mole of oxygen is 16 g and the universal gas constant is 8.
