Answer:
Total resistance = 0.92Ω
Explanation:
For parallel connected resistors we have effective resistance
Here parallel circuit made up of resistances of 2Ω, 3Ω, and 4Ω.
That is
R₁ = 2Ω
R₂ = 3Ω
R₃ = 4Ω
Substituting
Total resistance = 0.92Ω

Answer:
v = 1 m/s
Explanation:
from the principle of conservation of momentum, we have following relation
initial momentum = final momentum
where
m1 = 1.14 kg
v1 = 2.0 m/s
m2 = 1.14 kg
v2 = 0 m/s
putting all value in the above equation
v = 1 m/s
The ball's vertical velocity at the time it just passes over the goal is 0 m/s. Its initial vertical velocity is unknown and we denote it by , where
here is the ball's initial speed. Vertically, the only force acting on the ball is gravity, which attributes a downward acceleration of 9.8 m/s^2. We expect the maximum height achieved by the ball to be 2.4 m, so we can find the initial speed by solving
