Answer:
h = 38.41 m
Explanation:
Given that,
A ball is thrown horizontally from the top of a building and strikes the sidewalk after 2.8 s.
We need to find the height of the building. Let it is h.
Initial speed of the ball, u = 0
Using second equation of motion to find h as follows :
So, the building is 38.41 m tall.
Answer:
Water can carry electricity
Explanation:
While pure water does not conduct electricity, ionized water does. It is common that water is ionized than is pure, unless it is purified. The dissolved ions in the water are what makes the water conduct electricity. Handling electric equipment with wet hands may lead to electrocution.
In this system, solar energy from sunlight causes the solar panel to create solar energy which flows into the incandescent light bulb. In the light buld, the solar energy is transformed into two different types of energy: light energy and electric energy.
