In which type of circuit does charge move in only one direction? O A. An AC circuit
O B. A parallel circuit
O C. ADC circuit
O D. A combined circuit

it becomes positively charged by charging it

this could be newton#'s law of cooling. the cooling curve is exponential

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

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
