What can you say about the motion of an object: -
a. Whose distance-time graph is a straight-line parallel to the time axis?
b. If its speed time graph is a straight line parallel to the time axis? Draw the graph also.
Answers
Explanation:
Q:A
Answer☆
If distance time graph is a straight line parallel to the time axis, the body is said to be at rest. 3.
If distance time graph is a straight line parallel to the time axis, the body is said to be at rest. 3.Speed = Distance / Time: Velocity = Displacement / Time
If distance time graph is a straight line parallel to the time axis, the body is said to be at rest. 3.Speed = Distance / Time: Velocity = Displacement / TimeSpeed: Velocity
Q:B
Answer☆
Speed-time graph is a straight line parallel to time axis, it means that the speed of the object is not changing with time i.e., the object is performing uniform motion.
Answer:
The most abundant or easily synthesized actinides are uranium and thorium, followed by plutonium, americium, actinium, protactinium, neptunium, and curium.The lanthanides include the metals cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu).The lanthanides are the 14 elements from cerium (atomic number 58) to lutetium (atomic number 71). ... The actinides are the 14 elements from thorium (atomic number 90) to lawrencium (atomic number 103).
