Answer:

The average current density at the position of the area.

Explanation:

Current density is the vector whose magnitude is electric current in the cross sectional area. Current density is vector quantity which is measured in amperes. The average current density is dependent on the electric current flow. It has perpendicular direction of flow and scalar magnitude.

If a rock is thrown upward on the planet Mars with a velocity of 10 ms, its height in meters seconds later is given by (a) Find

Delicious77 [7]

Answer:

$1) X(t)=Xo+So(t)+\frac{1}{2} g(t)^{2}$

2) S(Δt)=So+g(Δt)

Explanation:

I think the equation they gave you for the Height upon time in seconds it's (1), where if you see, you will find the gravity, that you should multiply by 2 because, its divided by two in (1) (that should be your (a)), then, once you find your gravity, you can use the equation (2) to know the Final Speed replacing g , at the time asked, remember that g is gravity, and Δt is the: final time- initial time.

so in the [1,2] interval of time, your Δt=1s, and in [1,1.5] is Δt=0,5s.

i hoped it helped you even though i cant give you the exact answer right now.
