Why do astronomers use the astronomical unit to measure distance of the solar system?
Ivahew [28]
An astronomical unit is the measure of the center of the Earth to the center of the sun. 

Because our solar system is so vast, using mere miles is ridiculous, because they are too small to be helpful and the numbers will be in the billions. Astronomical units make it easier to think in small amounts.

Hope this helps :)

The velocity field of a flow is given by V = 3x2ti+[4y(t-1)+3x2t] j m/s, where x and y are in meters and t is in seconds. For fl
Katena32 [7]

Answer:

See explanations

Explanation:

Given that,

Electric field E=135V/m

Energy stored in 1m³of air=?

The energy stored in an electric field is given as

u = ½ εo E²

Where

U is the energy stored

εo is permissivity and it value is 8.85×10^-12C²/N..m²

And E is the electric field

Then,

U=½×8.85×10^-12×135²

U=8.06×10^-8J/m³

Then, the energy stored in 1m³ of air is 8.06×10^-8 J/m³

Use a(t) = −9.8 meters per second per second as the acceleration due to gravity. (Neglect air resistance.) A canyon is 800 meter
Kruka [31]

Answer:

t = 12.8 s

Explanation:

As we know that the deepest point of the canyon is 800 m

so here we will have the displacement of the rock in the canyon is same as that of depth of the canyon

So here we will say

\Delta y = v_y t + \frac{1}{2}at^2

800 = 0 + \frac{1}{2}(9.8) t^2

800 = 4.9 t^2

now we have

t^2 = \frac{800}{4.9}

t = \sqrt{163.6}

t = 12.8 s
