The shock wave from the meteoroid in the lower atmosphere has a Mach angle of 0.948°.
(a) The meteoroid's speed
Air sound wave speed
Speed of the shock wave in Mach
Hence, 0.948° is the Mach angle of the shock wave from the meteoroid in the lower atmosphere.
<h3>What is the speed of the meteoroid?</h3>A meteoroid's speed can be loosely broken down into three categories: slow, medium, and fast.

Answer:
The rms voltage (in V) measured across the secondary coil is 459.62 V
Explanation:
Given;
number of turns in the primary coil, Np = 375 turns
number of turns in the secondary coil, Ns = 1875 turns
peak voltage across the primary coil, Ep = 130 V
peak voltage across the secondary coil, Es = ?
The rms voltage (in V) measured across the secondary coil is calculated as;
Therefore, the rms voltage (in V) measured across the secondary coil is 459.62 V
The y-component of the acceleration is
Explanation:
The y-component of the acceleration is given by
where
is the y-component of the final velocity
is the y-component of the initial velocity
t is the time elapsed
For the ice skater in this problem, we have:
u = 2.25 m/s is the initial velocity, in a direction
v = 4.65 m/s is the final velocity, in a direction
t = 8.33 s is the time elapsed
The y-components of the initial and final velocity are:
So the y-component of the acceleration is

Answer:
t = 1.42 s and d = 35.5 m
Explanation:
Given that,
Velocity of a roadrunner is 25 m/s
A certain coyote wants to capture the roadrunner using a net dropped from an overpass that is 10 m high.
We need to find the time before the roadrunner is under the overpass and how far away from the overpass is the roadrunner when the coyote drops the net.
Let d is the distance traveled. So,
d = vt
d = 25 m/s × 1.42 s
d = 35.5 m
