Answer:
0.9 N, east
Explanation:
charge, q = 1 mC = 0.001 C
Electric filed, E = 900 N/C due east
Force, F = q E
F = 0.001 x 900
F = 0.9 N
The direction of force is same as the direction of electric field as the charge is positive in nature. So, the direction of force is also east.
Answer:
30Ω
Explanation:
To calculate the equivalent resistance in the circuit, do the following:
Step 1:
10Ω and 20Ω are in series connection. Therefore their equivalent is: 10 + 20 = 30Ω
Step 2:
The equivalent resistance (30Ω) obtained from the above is in parallel connection with 30Ω resistance shown in the diagram above.
Therefore their equivalent is given by:
1/30 + 1/30 = 2/30 = 1/15.
Now invert to obtain the equivalent
Therefore, the equivalent is 15Ω
Step 3:
Determination of the overall equivalent of the resistance of the circuit.
The new equivalent resistance 15Ω obtained above is in series connection with 15Ω resistance in the diagram above.
Therefore their equivalent is given by:
15Ω + 15Ω = 30Ω
Therefore, the equivalent resistance in the circuit is 30Ω

Hello
We know that the water's kinetic energy upon leaving will be converted into potential energy as it is projected straight up. The maximum height attained by the water is 29.6m.
We know Kinetic Energy is
1/2 * m * v^2
And Potential energy is
m*g*h
Equating,
(m*v^2)/2 = m*g*h
The mass cancels out from each side, making an object's mass irrelevant when its Kinetic and Potential energies are interchanging.
v = sprt(2gh)
v = sqrt(2*9.81*29.6)
v = 24.1 m/s
