dao động của 1 vật là tổng hợp của 2 dao động điều hòa thành phần cùng phương , cùng tần số , cùng biên độ là 3cm. biết dao động tổng hợp của vật có biên độ bằng 3cm. Tìm độ lớn lệch pha giữa 2 dao động thành phần

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.

Which equation is mostly likely used to determine the acceleration from a velocity vs time graph
