Which of the following has the lowest density ? a. mineral water b. water c. oxygen d. salt water

c

Explanation:

Mineral water, water, and salt water are all liquid solutions, while oxygen is a gas. Gases are less dense than liquids.

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

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
