Determine the half-life of uranium-238 using the graph below. 8 billion years

4.5 billion years

23 billion years

15 billion years

electromagnetic waves travel through space with vacuums. give me brainliest if right.

an energy transformation flow diagram is shown

where is it ?

i think its c if i'm wrong

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
