Homework Help Overview

The discussion revolves around various physics problems related to gravitational effects, energy transfer, and motion, particularly in the context of preparing for the NSO (National Science Olympiad). The original poster presents multiple questions that involve concepts such as distance covered under different gravitational conditions, energy imparted to a see-saw, and the effects of gravity on buoyancy and motion.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to understand why distance covered on the moon remains the same despite lower gravity, how to calculate the height reached by a see-saw given an energy input, and the implications of reduced gravitational effects on buoyancy. They also inquire about the water pump's performance at a specific height and the motion of a ball after losing energy.

Discussion Status

The discussion appears to be in its early stages, with participants encouraged to share their thoughts. There is a lack of detailed responses or attempts to solve the problems presented, and some participants express frustration over the original poster's approach of merely listing questions without attempts at solutions.

Contextual Notes

The original poster mentions feeling overwhelmed and unable to find relevant information in their textbook, indicating a possible gap in understanding or resources. The context suggests that these questions are part of their preparation for an upcoming examination.

1. A man covers 60m distance in 1 minute on the surface of the earth.. Distance he will on the moon in 1 minute will be equal to 60 m even though gravity is low. Why?

2. A girl of mass 20kg sits on the seat of see-saw initially impart an energy 400 J to the see-saw. Then at what height her see-saw will reach from the ground?

3. If there is a reduction in the gravitational effect then which of the following force do you think will change in some respect?
The correct option from some given choices was Archimede's uplift.

How on Earth can happen this?

4. Ramesh's house is situated at a height of 10m. The amount of water drwan by his water pump (power 2kW) in one minute would be_________

5. A ball 'm' of mass 1 kg drops from slab on a sand where it loses its 20% energy. Afterwards it starts moving in the forward direction and comes to rest in 10 s. The distance covered by ball is __________________

These were some question I came across while studying for NSO which I will be giving next year. I have thought about each of these questions earlier also and I have looked for the in my class textbook, but none seems to strike. Please help me soon. I find myself completely at sea to see them. Help Please. Thanx in advance!

If you have thoughts, then you should present them.

Well, I have already put what I knew...:eek:
 
All you did was list the questions! At least make an attempt to answer them.
