Now let's focus on the descending sphere. let m be the mass of the sphere, g be the acceleration due to gravity, t be the magnitude of the force of tension of the string, a be the acceleration of the sphere as it descends, and α be the angular acceleration of the wheel. what is the correct expression for newton's second law applied to the descending sphere? a. mg+t = ma
b. mg+t = mα
c. mg-t = ma
d. mg-t = mα
e. -mg+t = ma
f. mg-tr = ma
g. mg+tr = ma

Adisk with a radius of r is oriented with its normal unit vector at an angle q with respect to a uniform electric field. which of the following would result in an increase in the electric flux through the disk? check all that apply? a. increasing the area of the disk b. decreasing the given orientation angle of the disk c. decreasing the strength of the electric field d. increasing the given orientation angle of the disk, but not exceeding an angle of 90
