Answer:
C. contains negatively charged particles
Explanation:
- J.J Thomson placed two opposite charged electric plates around a cathode ray tube which is a sealed glass tube with high vacuum
- He found that a beam of negatively charged particles are generated in the tube which got attracted to the positively charged plate.
- These subatomic particles are called electrons and they have negative charge.
The oldest lunar rock samples are approximately 4.4 billion years old and composed of anorthosite, a mineral that crystallizes and rises to the top of a lava ocean.
The answer would be D, negative acceleration
The answer is "Spring Tide" which comes from the English word springen
Answer:
A. 1.6 × 105 joules
Explanation:
As per the question, the data given in the question is as follows
Number of masses = 2
Each weightage =
Speed = 12.5 meters/ second
Based on the above information, the approximate kinetic energy after the collision is
A perfectly elastic collision is described as one where the collision does not cause any loss of kinetic energy.
So we sum the kinetic energy of each kind of system which is given below:
Kinetic energy is
= 156250 J
