Yes. Everybody on Earth sees the same moon phase at the same time.
Explanation:
Using p1p1=p2p2
(75-73.5)x8=(X - 74)X 6
1.5 X 8= 6x-444
12=6x-444 (add 12)
6x=456 (divide by 6)
X= 76cm
Therefore the answer for the barometric height is 76cm
Answer:

Explanation:
The energy, E, from a capacitor, with capacitance, C, and voltage V is:


If we increase the Voltage, the Energy increase also:


The voltage difference:


Answer: option (D)
Explanation:
The potential energy of each of the students is given below as
P.E(student A) = mgh, where m = mass of student A, g is acceleration due to gravity and h = height of the high dive structure.
The mass of student B is twice as much as that of A, hence his mass is 2m and his potential energy is given below as
P.E ( student B) =2mgh = 2(mgh)
Recall that the relationship between potential energy and work done is that
Work done = - (change in potential)
For student A, work done = - mgh
For student B, work done = - 2mgh
From the equations above it can be seen that student B will do twice the work in getting to the high dive structure than student A hence validating option D.
