Answer:
a)
b)
Explanation:
You have that the angular displacement is given by:
a) the angular velocity is given by the derivative in time, of the angular displacement, that is:
b) the angular acceleration is the derivative, in time, of the angular velocity:
Compared to the charge on a proton, the amount of charge on an electron is same and has the opposite sign
Answer:
the first one
Explanation: the first one because they were all on two different continents so when they seperated half of the species went on one continent and the other half went onto another one
1.) Power, P = V²/R = 800²/45 = 4.5 W (A).
2.) Six Resistors in Series.
R = R1 + R2 + R3 + R4 + R5 + R6, Since R is the same, R = 20
R total = 6*20 = 120 (D)
3.) It is the current. Series connection is to evaluate current. (B)
Answer:
a = G M / R^2 acceleration at surface
a2 / a1 = (R1 / R2)^2 = (1/2)^2 = 1/4
The acceleration would be 1/4 of its original acceleration
