The two halves of a uniform circular cylinder are held together by a string passing through the cylinder with two objects of mass P (kg) at each end as shown in the figure. A circular cylinder has a given mass Q (kg). The plane of contact between the two halves of the cylinder is vertical. Determine the minimum value of P such that both halves of the cylinder are in equilibrium

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
