Answer:
42.5W
Explanation:
To solve this problem we must go back to the calculations of a weighted average based on the time elapsed thus,

We need to calculate the average power dissipated by the 800\Omega resistor.
Our values are given by:


Aplying the values to the equation we have:



In empty space, there's nothing to exert force on the ball after it leaves
her hand. It sails away in a straight line, at constant speed of 13 m/s.
If it doesn't sail too close to a planet, a star, an asteroid, or a moon, it
may travel 6 billion light years and still be moving at 13 m/s.
Answer: The second option.When
the current flows up the wire, the magnetic field flows out on the left
side of the wire and in on the right side of the wire.Explanation:
The first figure that I copy here with is the figure corresponding to this question.
The thumb is pointing upward.
The rule is that the thumb aims to the direction of the flow of current and the other fingers give the field lines.
The second figure that I attach is a free image from internet and it shows the direction of both the current and the fiedl lines.
So, the conclusion is that
the current goes upward the wire and the field lines go out of the paper (screen) for the points to the left of the wire and in on the right side of the wire.
Answer:
6.7 m/s
Explanation:
In the vertical direction:
y₀ = 0.63 m
y = 0 m
v₀ᵧ = 0 m/s
aᵧ = -9.81 m/s²
In the horizontal direction:
x₀ = 0 m
x = 2.4 m
aₓ = 0 m/s²
Find: v₀ₓ
First, find the time:
y = y₀ + v₀ᵧ t + ½ aᵧt²
0 = 0.63 + (0) t + ½ (-9.81) t²
t = 0.358
Now, find the velocity:
x = x₀ + v₀ₓ t + ½ aₓt²
2.4 = 0 + v₀ₓ (0.358) + ½ (0) (0.358)²
v₀ₓ = 6.70
Rounded to two significant figures, the cat's velocity when it slides off the table is 6.7 m/s.
