Block a which is at rest on a horizontal surface is used to hold block b with a mass of 56 kg in the air at a certain height above the ground the two blocks are connected with rope are which makes an angle of 35 degrees with the vertical block been suspended from the ceiling with cable see what is the magnitude of the resultant force acting on block b? Determine the horizontal component of the force in rope R

calculate the vertical component of the force in cable C

calculate the angle between the cable and the ceiling​

Amodel rocket with a mass of 0.212 kg is launched into the air with an initial speed of 84 m/s. how much kinetic energy will the rocket have at a height of 214 m? assume there is no wind resistance. 634 j 303 j

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?
