Answer:
1.03 m/s
Explanation:
I'm too lazy to write the explanation down but my teacher graded this and it was right
Answer:Paper and plastic!
Explanation:
(20 N)/(2 m²) = (20/2) N/m² = 10 Pa
_____
The pascal (Pa) is the derived SI unit of pressure equal to 1 N/m².
Wave D has the same wavelength as wave A, but the amplitude is lower. The answer is Wave D.
If you increase the mass m of the car, the force F will increase, while acceleration a is kept constant. Because F and m are directly proportional.
If you increase the acceleration a of the car, the force F will increase, while mass m is kept constant. Because F and a are directly proportional.
How can Newton's laws be verified experimentally; is by setting this experiment, and changing one variable while keeping the other constant, then observe the change in F.
Hope this helps.
