estimate

To use solar energy to fulfill electricity requirements, one has to install the solar structure on the rooftop of their house. can you estimate the roof area required to install the solar structure needed to fulfill all electricity needs?

The average solar panel has an efficiency of around 15-20%, meaning it can convert 15-20% of the sunlight it receives into electricity. So, to produce 30 kWh of energy per day, you would need a solar panel system with a total capacity of around 150-200 square feet of solar panels.

Apart from electricity, one uses petrol/diesel for driving vehicles and lpg for cooking food. can you estimate the amount of total energy used or consumed in terms of kilo-watt-hour or kwh?

Right now, gas and diesel vehicles make up 97% of the U.S. auto market. Electric vehicles still cost more upfront, and America doesn't have the electric grid or charging infrastructure to support.

Raindrops of radius 1 mm and mass 4 mg are falling with a speed of 30 m/s on the head of a bald person. the drops splash on the head and come to rest. assuming equivalently that the drops cover a distance equal to their radii on the head, estimate the force exerted by each drop on the head.
