Answer:
Rp = 10 Ohms; I = 0.9 Amps
Explanation:
Since, there are two resistors each with 20Ω connected in parallel, the total resistance of the combination (Rp) of the circuit is as follows:
i.e 1/Rp = (1/R1 + 1/R2)
1/Rp = (1/20Ω + 1/20Ω)
1/Rp = (1 + 1)/20Ω
1/Rp = 2/20Ω
1/Rp = 1/10Ω
To get the value of Rp, cross multiply
Rp x 1 = 10Ω x 1
Rp = 10Ω
Apply the formula
Voltage V = Current I x Total resistance Rp
I = V/Rp
I = 9V/10Ω
I = 0.9 Amps
Thus, the total resistance is 10 Ohms, the current through the ammeter is 0.9 Amps
Answer:

The answer is Mars
Mars has a rotational period closest to that of Earth. Mars is roughly longer than a day on Earth. This is by far the closest by over a hundred hours. Other than Jupiter which rotates less than 10 hours. Mars has a rotation of 24.75 hours or 1.03 Earth days.
To find the maximum height you have to calculate the initial velocity in the y axis..
to do that resolve the velocity vector in the y direction
which is equal to
[email protected]27*√3/2 = 23.4 m/s
thus using kinematics.
v^2 = u^2 + 2as
23.4*23.4 /19.6 = s
27.96 that's 28 m approximately
