The heat from Uyen's breathe causes heer to see her breathe visibly. The state that is responsible for it though is Vaporization and Condensation.
I hope this helps! (^_^)
Answer:
Part A W= 2772J
Part B = -2.772J
Explanation:
Work = force × distance
Part A when you move from lower to upper level
= mgh
= 63× 4.4×10
=2772J
=2.772KJ
Part B
When you move from upper to lower
The acceleration due to gravity becomes negative -10m/s^2
Therefore Work =-2772KJ
Work = -2.772KJ
Resistance of our body is given as

voltage applied across the body is

now by ohm's law current pass through our body is given by

![i = \frac{120}{30,000}[\tex][tex]i = 4 * 10^{-3} A](https://tex.z-dn.net/?f=i%20%3D%20%5Cfrac%7B120%7D%7B30%2C000%7D%5B%5Ctex%5D%3C%2Fp%3E%3Cp%3E%5Btex%5Di%20%3D%204%20%2A%2010%5E%7B-3%7D%20A)
So current from our body will be 4 * 10^-3 A
Answer:
Explanation:
magnetic field B = (3 i + 8 x 2 j )x 10⁻³ T
= (3 i + 16 j )x 10⁻³ T
L = - i ( unit length of conductor )
Force F = I ( L x B ) , I is current
= 5 [ - i x ( 3i + 16 j ) 10⁻³]
= 5 ( - 16 k ) x 10⁻³
F = - 80 x 10⁻³ k
