We don't know Carter, and we don't know where he is or what
he's doing, so I'm taking a big chance speculating on an answer.
I'm going to say that if Carter is pretty much just standing there,
or, let's say, lying on the ground taking a nap, then the force of
the ground acting on him is precisely exactly equal to his weight.
Answer:
change in frequency is 636 Hz
Explanation:
given data
speed v1 = 36 m/s
speed v2 = 45 m/s
frequency f = 500 Hz
speed of sound s = 343 m/s
to find out
what is the change in frequency
solution
we know here change of frequency formula that is
frequency = 
(f) ...................1
put here value in equation 1
and we take v2 = -45 because opposite direction
frequency = 
(f)
frequency = 
(500)
frequency = 636
so change in frequency is 636 Hz
Answer:
0.480 seconds
Explanation:
The period is the time for 1 revolution. Writing a proportion:
14.4 s / 30.0 rev = t / 1 rev
t = 0.480 s
The period is 0.480 seconds.
Answer:
c) 2 blocks
Explanation:
Her displacement is the difference between her starting point and her ending point.
Let's say she starts at the origin, (0, 0).
First, she goes 13 blocks east: (13, 0)
Next, she goes 4 blocks north: (13, 4)
Then she goes 8 blocks west: (5, 4)
Then she goes 6 blocks south: (5, -2)
Finally, she goes 5 blocks west: (0, -2)
The magnitude of her displacement is the distance between her initial and final positions: 2 blocks.
