The correct answer is option A, 3.528 N
In this question the water has nothing to do, the gravity always pull the object with the same magnitude irrespective of the medium.
The force of gravity is calculated as
F=0.09*4000*9.8
=3.528 N
Answer:
a current will be induced.
Explanation:
If the vertical component is 29.6 m/s down, and the horizontal component
is 54.8 m/s parallel to the surface, then the magnitude of the slanty vector is
√(29.6² + 54.8²) = √(876.16 + 3003.04) = √3879.2 = 62.28 m/s .
That's 139 mph ! Wow !
Answer:
for C-Cl bond 
for O-O bond 
Explanation:
- We have the bond enegy for C-Cl,

- bond enegy for C-Cl,

<u>Now as we know the energy of electromagnetic waves is given by:</u>

here E = BE
<u>Then for C-Cl:</u>


Now wavelength:



<u>For O2:</u>


Now wavelength:



Work = Force x displacement
Force= 20N
Displacement= 0.75m
W= 20(0.75)
W= 15 Nm
