Answer:
The magnetic field strength, the energy density, and the power flow per unit area are , and 13.18 W/m².
Explanation:
Given that,
Electromagnetic wave strength E= 70.5 V/m
(I). We need to calculate the magnetic field strength
Using formula of Electromagnetic wave strength
(II). We need to calculate the energy density
Using formula of energy density
(III). We need to calculate the power flow per unit area
Using formula of poynting vector
Put the value into the formula
Hence, The magnetic field strength, the energy density, and the power flow per unit area are , and 13.18 W/m².
The answer to your question is D
Answer:
1.Free edge
2.Nail Root
3.Nail matrix
4.lunula
Note: The numbering coincides respectively with the dashes in the questions.
Explanation:
Free edge is the distal white nail ending.
Nail Root is the proximal part of the nail embedded in the skin.
Nail matrix is the actively growing part of the nail were the nail root thickens
Lunula the whitish semilunar area of the proximal end of the nail body it appears whitish because stratum basala obscures. the underlying blood vessels.
Explanation:
First, we will calculate the torque because of the rope wrapped around the drum as follows.
torque1, =
= 3.496 N m
Now, we will calculate the torque because of the rope around the core as follows.
torque2, =
= 3.046 N m
(Since, we are provided with any figure which means that the torque can act either in the same direction or in the opposite direction.)
So, if the torque is acting in the same direction then,
torque = torque1 + torque2
= (3.496 + 3.046) N m
= 6.542 Nm
And, if the torque is acting in the opposite direction then,
torque = torque1 - torque2
= (3.496 - 3.046) Nm
= 0.45 Nm
Answer:
806.6 N
Explanation:
Given that :
Mass (m) = 74 kg
Acceleration due to gravity (g) = 9.8 m/s²
Acceleration during interval t1 = 1.10 m/s²
Using the relation :
Normal reaction = Mass (g + acceleration at interval t1)
Normal reaction = 74(9.8 + 1.10)
Normal reaction = 74(10.9)
Normal reaction = 806.6 N
