Energy can be conserved by group of answer choices replacing mass transit with more and larger roads for cars and trucks using cogeneration in automobiles, especially in suvs using cogeneration in power plants, fuel efficient transportation, and reengineered lightbulbs and appliances replacing compact florescent with tungsten bulbs

true is the correct answer

hope i

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
