Knowing that the momentum(p) of an object is directly (when one number goes up the other will too) related to both the mass and velocity of an object or p=mv, two rolling bowling balls of different masses can have the same momentum because the one with the lower mass, has a higher velocity. The higher velocity of an object would make up for the lower mass and vice versa.

Answer:
Water that contains a larger than normal amount of <em>magnesium</em> is still safe to drink.
Explanation:
Sulfur, lead and arsenic are harmful metals that are toxic to human health. Although magnesium present at high concentrations (above approximately 250 mg/l each) can have a laxative effect. However, data suggest that consumers adapt to these levels as exposures continue.
The electric field generated by a proton is a radial field, so we would see the field lines going radially from the proton toward every direction. I've attached a picture representing the electric field generated by a positive charge, such as a proton, and we can see the field lines going radially from the charge toward every direction.
Answer:
Explanation:
let A represent me and B represent my friend
A speed=30 m/hr toward west
B speed =40 m/hr toward south
after 1/2 hr
total distance cover by A =1/2 * 30 miles = 15 miles
total distance by B = 1/2*40 miles = 20 miles
now from figure
Differentiate above equation
