Answer:
Streams need vitality to move material, and levels of vitality change as the waterway moves from source to mouth.
At the point when vitality levels are high, huge rocks and stones can be moved. Vitality levels are generally higher close to a waterway's source, when its course is steep and its valley slender. Vitality levels rise considerably higher in the midst of flood.
At the point when vitality levels are low, just little particles can be moved (assuming any). Vitality levels are most reduced when speed drops as a waterway enters a lake or ocean (at the mouth).
Answer:
Mass is the same, weight is less.
Explanation:
We know the following equation
W = mg
where m is the mass of the astronaut which is constant and W is the weight. As g (the acceleration due to gravity) is a variable which it is directly proportional to the W, if g is lower on the Moon than on Earth, then W is lower on the Moon than on Earth.
The period of a simple pendulum depends only on the length of the pendulum and the gravitational acceleration:
where L is the pendulum length and g the gravitational acceleration.
The problem says that Maya and the swing form a simple pendulum, so we can use this formula to calculate the period of Maya's motion, using the length of the swing (L=1.8 m):
