Answer:
Lower than
Explanation:
When the cube is placed on the raft, the displaced water equals the combined weight of both the cube and raft. In contrast, when submerged in water, the displaced water corresponds to the raft's weight plus the cube's volume. Since the cube's volume is smaller than what is needed to displace its weight with water, the water level is lower.
The new charge of the ball will amount to 8x10^8C after removing 5x10^27 electrons.
Explanation:
Initially, if the sphere is electrically neutral, its charge stands at 0C.
When an electron with a charge of (-1.6*10^-19 C) is taken away, we effectively add a positive charge, leading to:
1.6*10^-19 C as the sphere's new charge.
For a total of N electrons removed, the sphere's overall charge now becomes:
N*1.6*10^-19 C.
To calculate N when:
N*1.6*10^-19 C = 8.0x 10^8 C.
We find that N is: (8.0/1.6)x10^(8 + 19) = 5x10^27 electrons.
Answer:
The power used by raul's microwave must match the power consumed by katrina's because both microwaves took different durations to accomplish the same heating task.
Explanation:
The power output from a car engine is equivalent to that of a bicycle since both perform the same amount of work over time. Both raul and katrina shared a frozen meal, heating each portion in different microwaves. Katrina's portion was warm in one minute, whereas raul's portion required two minutes. Therefore, the power utilized by raul's microwave aligns with that of katrina's, given that it took longer to achieve the same result.
