Answer:
b) Distance covered before stopping.
Explanation:
If you want to find the distance d required to come to a stop starting at some initial speed v, with braking acceleration a, use the kinematic relation
vf2 - vi2 = 2ad
vi = initial speed at the moment braking begins = v
vf = final speed = 0 (comes to a full stop)
-v2 = 2ad
d = -v2/(2a)
Answer:
P waves are a type of seismic wave that is characterized by being a longitudinal mechanical wave, which means that the medium through which they travel is alternately compressed and dilated in the<u> same direction of propagation</u>. This means they propagate in a similar way to the sound.
These waves are faster than the S waves, so when an earthquake occurs these waves <u>are the first to be recorded by the seismograph</u>. They can also travel through any type of material (solid, liquid or gaseous), this means they are able to <u>travel through solid rocks as well as in oceans or volcanic magma and are even able to be </u><u>transmitted through the atmosphere</u>, that is why they are sometimes perceived by people and animals as a deep sound.

Answer:
<em>The second option has a lower power output. P=30 W</em>
Explanation:
<u>Mechanical Power
</u>
It is a physical magnitude that measures the rate a work W is done over time t.
Since W=F.d
The first option means the worker will lift the box by a distance of 1.2 meters in 3 seconds by applying 250 N of force. That produces a power of
The second option requires the worker applies 75 N of force and travel a distance of 4 meters for 10 seconds, thus the power is
The second option has a lower power output
