Hi there!
p(a∩b) = 0.
Since a and b are mutually exclusive events, there is no overlap or intersection of events.
These two events CANNOT both occur, so the intersection of p(a) and p(b) does not exist.
Thus, p(a∩b) = 0.
Answer: The particle model, because only high-energy frequencies of lights can remove electrons.
Explanation: just did the test and got it right :)
Answer:

Answer:
B. South
Explanation:
An electric field can be defined as the amount of electric force per unit charge. The direction of the electric field can be determined by the motion of a positive test charge under the electric force.
The direction of electric field is radially outward for a positive charge and radially inward for a negative charge. Thus, for the electric field points toward SOUTH at a position directly south of a positive charge.
Answer:
The height of the cliff is 28.57 m.
Explanation:
Given;
initial velocity of the rock, u = 12.6 m/s
time of motion, t = 1.45 s
The height of the cliff is given by;
h = ut + ¹/₂gt²
h = (12.6 x 1.45) + ¹/₂(9.8)(1.45)²
h = 18.27 + 10.30
h = 28.57 m
Therefore, the height of the cliff is 28.57 m.
