The relationship between mass and acceleration is inversely proportional, so as one goes up the other goes down. In this case, acceleration would decrease since mass is increased
Force can be expressed as the time-rate change of momentum
Mathematically, Force = Change in momentum/change in time
Change in momentum = m(10.1-18.9) = -0.2024
Force = -2024/5.4 = -375N(approx)
The significance of the '-' sign is that the direction of force is the opposite that of the direction of our velocities since we assumed them to be positive.
Also this is the force on the ball, the force on the window will be equal and opposite.
Answer:
it depends most of the time but i don't really have a clue either
Answer:
Plasma is by far the most common form of matter. Plasma in the stars and in the tenuous space between them makes up over 99% of the visible universe and perhaps most of that which is not visible. On earth we live upon an island of "ordinary" matter.
Answer:
The heat rejected is 146J.
The work done by the engine is 54J.
The thermal efficiency is 0.27
Explanation:
The efficiency of the carnot engine, which is working between a hot source at a temperature and a cold source at a temperature , is given by:
The normal boiling point of water is 373 K. ()
The temperature of triple point of water is 273.15 K ()
