How can you tell what minerals occur in a cement? Simply remember the basic physical properties of the minerals (e. g., hardness, the ability to react with HCl, color). With these properties in mind, answer the following questions concerning sandstone, a type of sedimentary rock consisting of cemented-together grains of quartz sand. he cement (but not the grains) in a sedimentary rock reacts when in contact with dilute HCI. The cement consists of .

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

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
