Answer:
The answer is 0.47 watts
power is calculated by Work/Time
14/30 =0.46666666 which is approximately 0.47watts
<span>The statement, a hard material
is easily scratched, is false, the answer is letter F. Harder materials have
strong bonding between their neighboring atoms and it takes a greater amount of
energy for them to break apart, even a scratch. The relative hardness of a
mineral can be tested by the Moh’s scale or the mineral hardness. The Moh’s
scale can be characterized by the ability of the mineral to resist scratch
resistance by scratching a harder or softer mineral. It has a scale of 1 to 10
where 1 being the softest and 10 being the hardest.</span>
Newton's 3rd law says that for every force there is an equal and opposite reaction force.
So for the force of the hammer hitting the nail, there is a force equal in magnitude exerted back on the hammer by the nail (and is "opposite" because it's in the other direction and on the hammer.)
Answer:
Positive charge is in the dough in which the negatively charged plums are embedded.
Explanation:
The faster a stream flows, the larger the size of particles it is able to transport.
Fast moving stream due to their velocity and momentum can exert more force and impact larger materials more causing them to move readily.
- The faster the speed of stream the larger the size of sediment it is able to transport.
- This why the edges of oceans contains very coarse particles whereas the still deeper waters are made up of fines.
- A stream is able to transport sediments in three forms:
- As solution in dissolved forms
- As bedload which made up of large boulders.
- As suspension
