Answer:
4.5m/s
Explanation:
Linear speed (v) = 42.5m/s
Distance(x) = 16.5m
θ= 49.0 rad
radius (r) = 3.67 cm
= 0.0367m
The time taken to travel = t
Recall that speed = distance / time
Time = distance / speed
t = x/v
t = 16.5/42.5
t = 0.4 secs
tangential velocity is proportional to the radius and angular velocity ω
Vt = rω
Angular velocity (ω) = θ/t
ω = 49/0.4
ω = 122.5 rad/s
Vt = rω
Vt = 0.0367 * 122.5
Vt =4.5 m/s
It depends whether or not the object in moving relative or not to the reference point, for instance imagine a void where there were no dimensions, but there was an object. You can’t tell if the object is moving or not without a reference point.

Explanation: for exmp 1/4 x 1/9=
Yes. With converging plates, where two plates are touching
towards each other instigating one to sub duct beneath the other, you incline
to have volcanoes and earthquakes. Instance: In Asia, the Pacific Plate touching
to and beneath the Eurasian Plate. Another example of where you would have
earthquakes is where two plates are slipping in contrary directions parallel to
one another. This is an instance of the Pacific Plate touching next to the
North American Plate. This makes faults or crashes in the plates instigating
earthquakes. As the plate slip past each other, subsequently separately plate
boundary isn't flawlessly smooth, they catch on one another and accumulate pressure.
When the pressure is free, the energy is gave out as an earthquake.
Answer:
Explanation:
As per Doppler's effect we know that the frequency of the sound that is observed by the detector is the reflected sound
This reflected sound is given as
so we know that the beat frequency is
so we will have
so we have
