The answer to this question is False.
Use newton's second law, F = ma.
Force is 34 N and a is 4 m/s/s
34 = m(4), solve for m.
34/4 = 8.5 g
Answer:
313, 0.60 s
Explanation:
wavelength
= speed/frequency
= 340/520
= 0.6538 m
Number of wavelengths
= 205/0.6538
= <u>313</u> (whole number)
Time delay
= distance/speed
= 204/340
= <u>0.60 s</u>
Answer:
60 m
Explanation:
The boat has two separate motions:
1- A motion due north, with constant speed of 10 m/s
1- A motion due east, due to the current, at speed of 2 m/s
We know that the river is 300 m wide, so we can consider first motion 1) to find how much does it take for the boat to cross the river:

Now we can find how far downstream the boat moved by calculating the distance that the boat covered moving east during this time interval:

The height has gained gravitational potential energy.
