The answer to your question is 10.24
The answer i got is 133.3 but i’m not completely sure . I got that because to get velocity i’m pretty sure it’s distance over time. So in between 8 and 10 minutes it’s 9 minutes. I pretty much just did 1200 divided by 9.
sound energy hope this helps please give brainliest
Answer:
3.8 m/s
Explanation:
Momentum is the product of mass and velocity hence
Momentum=mv where m is mass and v is the velocity of an object
Making v the subject of the formula then
Substituting 1710 kgm/s for momentum and 450 Kg for mass we obtain
Hence the speed of dogsled team is 3.8 m/s
Answer:
energy carried by the current is given by the pointyng vector
Explanation:
The current is defined by
i = dQ / dt
this is the number of charges per unit area over time.
The movement of the charge carriers (electrons) is governed by the applied potential difference, when the filament has a movement the drag speed of these moving electrons should change slightly.
But the energy carried by the current is given by the pointyng vector of the electromagnetic wave
S = 1 / μ₀ EX B
It moves at the speed of light and its speed depends on the properties of the doctor and is not disturbed by small changes in speed, therefore the current in the circuit does not change due to this movement
