Answer:
Explanation:
Given:
- power of battery,
- voltage across the load resistor,
- emf of the battery,
<u>Now as we know that the electric power is given as:</u>
here: resistance of the load
a)
Now the load resistance:
b)
Using Ohm's law, current in the load:
Now,
where: internal resistance
The answer is they have many moons, they also are all made up of hydrogen and helium. All outer planets necessarily have rings and they are called "Gas Giants" because they are large and very gaseous. Saturn has therings that you can see though,
Outer Planets:
Jupiter
Saturn
Uranus
Neptune

Answer:
a. The horizontal component of acceleration a₁ = 0.68 m/s²
The vertical component of acceleration a₂ = -0.11 m/s²
b. -9.19° = 350.81° from the the positive x-axis
Explanation:
The initial velocity v₁ of the fish is v₁ = 4.00i + 1.00j m/s. Its final velocity after accelerating for t = 19.0 s is v₂ = 17.0i - 1.00j m/s
a. The acceleration a = (v₂ - v₁)/t = [17.0i - 1.00j - (4.00i + 1.00j)]/19 = [(17.0 -4.0)i - (-1.0 -1.0)j]/19 = (13.0i - 2.0j)/19 = 0.68i - 0.11j m/s²
The horizontal component of acceleration a₁ = 0.68 m/s²
The vertical component of acceleration a₂ = -0.11 m/s²
b. The direction of the acceleration relative to the unit vector i,
tanθ = a₂/a₁ = -0.11/0.68 = -0.1618
θ = tan⁻¹(-0.1618) = -9.19° ⇒ 360 + (-9.19) = 350.81° from the the positive x-axis
