D.Atoms can be divided into smaller parts.
Dalton's atomic theory was the first complete attempt to describe allmatter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that allmatter is made of atoms, which are indivisible.
Complete Question
The light energy that falls on a square meter of ground over the course of a typical sunny day is about 20 MJ . The average rate of electric energy consumption in one house is 1.0 kW .
If light energy to electric energy conversion using solar cells is 12 % efficient, how many square miles of land must be covered with solar cells to supply the electrical energy for 350000 houses? Assume there is no cloud cover.
Answer:
The area is 
Explanation:
From the question we are told that
The efficiency is
12%
The number of houses is 
The light energy per day is 
The average rating of electric energy for a house is 
Generally the electric energy which the solar cells covering
produces in a day is



Energy for required by one house for one day is

Energy needed for 350000 house is

The area covered is mathematically represented as


There is a push and pull exerted on the object while it is falling which is called gravity/force.
Given that,
Mass of a box, m = 11 kg
It is lifted to a height of 6 m
Time, t = 3s
To find,
The power experienced by the Peter.
Solution,
Power = rate of doing work

So, the power experienced by the Peter is 215.6 Watts.
A scalar quantity is a one dimensional measurement of a quantity, like temperature, or mass. A vector has more than one number associated with it. A simple example is velocity. It has a magnitude, called speed, as well as a direction, like North or Southwest or 10 degrees west of North.
