D has the least number so its D
None of the choices is a suitable fill-in for the blank.
The question is fishing for "solution", but that makes
the statement false and misleading.
Salad dressing is a well-blended mixture.
Blood is a well-blended mixture.
Milk is a well-blended mixture.
Petroleum is a well-blended mixture.
None of these substances is a solution.
A solution is not a well-blended mixture.
Transformation of energy, because energy cannot be created or destroyed
Answer:
435 m
Explanation:
The precision with which the distance to the source of the earthquake can be estimated is equal to the difference in distance covered by the S- and P-waves in the time of 0.125 s.
The distance covered by each type of wave is given by
where
v is the speed of the waves
t is the time
For S-waves,
v = 3.74 km/s
t = 0.125 s
So the distance covered is
For P-waves,
v = 7.22 km/s
t = 0.125 s
So the distance covered is
So, the precision with which the distance can be determined is:
Answer:
the correct amount
Explanation:
The pan balance has two pans . When the elevator is accelerating upward , the apparent weight of both objects placed on either pan increase . The net effect is that they cancel out the effect of accelerating elevator . Hence the apparent weight of salt remains same as and equal to its real weight.
In case of spring balance, its apparent weight would have increased . Its apparent weight would have measured more than its true weight.
