More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.
Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.
Answer:
38.
Explanation:
All water that are present in soil is not available for the plants. Gravitation water is present in soil due to the gravitational force. The gravitation water remains for short time and cannot be consumed by the plants.
The capillary water is available to the plants and this water is attained in the soil pores. The total water present in soil sample is 100 ml. 62ml is gravitation water. The volume of capillary water = total water - gravitation water = 100 - 62 = 38ml.
Thus, the answer is 38ml.
Your answer is D (4)
