Answer:
_s = 37.77 m / s
Explanation:
This is an exercise of the Doppler effect that the change in the frequency of the sound due to the relative speed of the source and the observer, in this case the observer is still and the source is the one that moves closer to the observer, for which relation that describes the process is
f ’= f₀ 
where d ’= 530 Make
when the ambulance passes away from the observer the relationship is
f ’’ = f₀ 
where d ’’ = 424 beam
let's write the two expressions
f ’ (v-v_s) = fo v
f ’’ (v + v_s) = fo v
let's solve the system, subtract the two equations
v (f ’- f’ ’) - v_s (f’ + f ’’) = 0
v_s = v 
the speed of sound is v = 340 m / s
let's calculate
v_s = 340 
v_s = 340 
)
v_s = 37.77 m / s

Answer:1.33 times
Explanation:
Given
A takes 30 sec to complete each length
While B takes 40 sec to complete each length
Let L be the Length of Swimming pool Length
and 
and 
be the length of A & B
Thus after 5 minutes A traveled
so A is 2.5L units ahead of B
A has traveled 1.33 times than B in 5 mins
Explanation:
The given data is as follows.
M = 35 kg, radius (r) = 2.2 m,
m = 17 kg, = 11 rad/s
We assume that will be the final angular speed.
Now, according to the conservation of angular momentum.
or, 
Putting the given values into the above formula as follows.
or,
= 
= 7.58 rad/s
Thus, we can conclude that the angular speed of the clay and turntable is 7.58 rad/s.
Answer:
The gravitational force on a mass is its weight. We can write this in vector form, where
→
w
is weight and m is mass, as
→
w
=
m
→
g
.
In scalar form, we can write
w
=
m
g
.
Since
g
=
9.80
m/s
2
on Earth, the weight of a 1.00-kg object on Earth is 9.80 N:
w
=
m
g
=
(
1.00
kg
)
(
9.80
m/s
2
)
=
9.80
N
