As Fey takes her last two measurements she notices that the temperature drops suddenly. Which of the following weather
predictions would be best for Fey to make?
OA. A hail storm is approaching.
OB. A cold front is moving in.
OC.
The air's humidity is decreasing.
OD
A tsunami is approaching.

probably not if net force is zero

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

there are no atoms

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
