Answer:
kinetic Energy = 12.58 GJ
Explanation:
1 metric ton is equal to 1000 kg
then,
93000 metric ton
Mass is m = 93000 x 1000 kg
speed is v = 32 knots
1 knot is 0.514 m/s
then
,
v = 32 x 0.514 = 16.448 m/s
To solve for the Kinetic Energy (KE), we have;
KE = 0.5 x m x v²
KE = 0.5*93000*1000*(16.448)²
= 12.58 x 
J
= 12.58 GJ
It represents the depolarization of the atria.
<u>Explanation:</u>
The P wave speaks to the depolarization of the left and right chamber and furthermore relates to atrial compression. Carefully, the atria contract a brief moment after the P wave starts. Since it is so little, atrial repolarization is typically not unmistakable on ECG.
In an ordinary ECG, there's three particular waves. The primary wave is the P wave, which speaks to the depolarization of the atria. This happens directly before the atria agreement and drive blood into the ventricles. The following wave is known as the QRS wave.
Answer:
Explanation:
The question relates to motion on a circular path .
Let the radius of the circular path be R .
The centripetal force for circular motion is provided by frictional force
frictional force is equal to μmg , where μ is coefficient of friction and mg is weight
Equating cenrtipetal force and frictionl force in the case of car A
mv² / R = μmg
R = v² /μg
= 26.8 x 26.8 / .335 x 9.8
= 218.77 m
In case of moton of car B
mv² / R = μmg
v² = μRg
= .683 x 218.77x 9.8
= 1464.35
v = 38.26 m /s .
Answer:
mechanical energyis the sum of all potential and kinetic energy.hope it helps!
The frequency of the re-emitted light is identical to that of the absorbed light.
To find the answer, we need to know more about the frequency of light.
<h3> Why the re-emitted light has the same frequency?</h3>
- The wavelength of the light that is momentarily absorbed in glass and then re-emitted is the same, which explains why the re-emitted light has the same frequency as the absorbed light and the frequency of the absorbed light is the same.
- An electromagnetic wave's energy is inversely related to its frequency.
- The relationship between the wave's wavelength and frequency depends on the speed of light:
, c is the speed of light.
- Despite not having mass, light still has energy, and that energy is conserved.
- As a result, in order for there to be energy conservation, the energy of the light that is received and reemitted must be equal.
Thus, we can conclude that, the re-emitted light's frequency matches the absorbed light's frequency.
