Answer:
D) not swim in or drink the water from the stream
Explanation:
Low pH means the water is acidic which is harmful to your skin as it can cause burns and irritations. So any means of contacting with water is not healthy. The damage to the skin happens as in acidic water it has more H+ than in the neutral water and the extra H+ ions can ionize the atoms which are combined to form different compounds in the skin when in contact.
Answer:
Mass and distance between them are two factors on which force of gravity depends
Explanation:
According to law of gravitation
Gravitational force between two object is given by , here G is gravitational constant are mass of the objects and r is distance between them
From the relation we can see that force of gravity is dependent on the mass of the objects and distance between them.
So mass and distance between them are two factors on which force of gravity depends
