Answer: the washer would slow down depending on how strong the magnet is even though the gravitational pull is the same. the change would be .6
Explanation: i don't really get it
Answer:
Explanation:
The formula for the force exerted between two charges is
where k is the Coulomb constant.
The charges are identical, so we can write the formula as
A scientist adds heat to each of the following substances. Which will probably absorb the most heat before its temperature changes significantly?
50 g of liquid water
A scientist discovers a new substance. The molecules of the substance form hydrogen bonds with each other. When the molecules lose a lot of energy, the hydrogen bonds hold them relatively far apart. Based on this information, what can the scientist infer about the substance?
It expands when it freezes.╖
Which of these best explains why a paper clip can float on water?
Water molecules near the surface produce more buoyant force than water molecules within the liquid.
Which of these best explains why the hydrogen atoms in a water molecule are attracted to Cl− ions in sodium chloride (NaCl)?
The hydrogen atoms have partial positive charges.
Answer:
Option C. vi = 0
Explanation:
An object held at a particular height above the ground is considered to be at rest. If the object is release from that height, the initial velocity (vi) is considered to be zero since the object is at rest or at a stand still position.
Thus,
Initial velocity (vi) = 0
