M=1000kg
a=2 m/s²
Thrust force= 5000N
a =F/m
2m/s² =(5000N-Drag force)/1000kg
1000×2 =5000-Drag force
2000b =5000-Drag force
Drag force= 5000-2000
Drag force= 3000N
Answer:
fire is a potential energy
Your list that you call "the following properties" is awfully short. / / / The displayed value tells you the car's speed relative to the pavement. (NOT its velocity.)
The answer is A) frequency
The amplitude of Wave 2 is greater than Wave 1's, as is the wavelength. You can see that Wave 2 has a higher period and greater peaks and troughs than Wave 1.
You can also see that Wave 2 has half the frequency, meaning Wave 1 completes 2 periods for every 1 period that Wave 2 completes.
Answer:
The more efficient the machine, the less energy wasted. For example, if a heat engine is able to turn 75 percent of the fuel it receives into motion, while 25 percent is lost as heat in the process, it would be 75 percent efficient
