Answer:
pulse = force * time
force = mg = 0.1kg * 10 = 1 N
time = 0.5
pulse = 0.5 f.s
I would have to say that it is Y
Answer:
m
Explanation:
Consider the motion of the boat across the stretch from west to east direction :
= velocity of boat = 15 mph
= length of the stretch = 1.01 miles
= Time taken to reach the opposite end
Time taken to reach the opposite end is given as
![t = \frac{L}{v_{b}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7BL%7D%7Bv_%7Bb%7D%7D)
![t = \frac{1.01}{15}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B1.01%7D%7B15%7D)
h
sec (Since 1 h = 3600 sec)
sec
= speed of river = 2.04 m/s
= distance traveled downstream
Distance traveled downstream is given as
![d = v_{r} t](https://tex.z-dn.net/?f=d%20%3D%20v_%7Br%7D%20t)
![d = (2.04) (242.3)](https://tex.z-dn.net/?f=d%20%3D%20%282.04%29%20%28242.3%29)
