The answer to this question is false
D) Both A and B.
Francisco Redi must use 1)a covered, unrefrigerated meat and 2) an uncovered, refrigerated meat to experiment and test his hypothesis that maggots came from flies rather than from meat.
Answer:
<h3>
</h3><h3>
Explanation:</h3>
Let U1 and U2 be the gravitational potential energy of the first and second stone respectively.
U1 is given by:
and U2 is given by:
therefore, comparing the energies we have:
therefore:
Answer: 2000 v/m, from B to A.
Explanation: if point A is at the origin (x=0m) and point B is at the point x= 0.150m, the distance between both points (d) = 0.150 - 0 = 0.150m
Point A is at a 200v potential and point B is at a potential of 500v.
Difference in potential produces a voltage (v) = 500 - 200 = 300v.
The relationship between voltage, electric field intensity and distance is given by the formulae below
v=Ed
Where v = voltage = 300v, electric field =?, d = 0.150m
300 = E×0.150
E = 300/0.150
E = 2000 v/m.
Since point B is at higher potential than A, it implies that if there is an electron in this field, it will move from B to A thus making the direction of field be from B to A.
