Kepler's Law (3)

T² ≈ r³

The square of the orbital period ≈ the cube the distance to the sun

The farther away the planet is, the bigger the radius, the bigger the period

Anna71 [15]

Answer:

life in europa is possible due to chemical energy, surface and ocean intracts with one another and give off chemical energy.

Explanation:

the ocean in europa is in contact with the underlying rocky mantle and at high temperatures, its rocks and water interact. oxidization and reduction in which molecules give off and accept electrons occur in it  and in deep ocean, when chemically reduction vent fluids interacts with oxygen containing seawater to produce energy that can support micro-organisms and animals.

A straight wire in a magnetic field experiences a force of 0.023 N when the current in the wire is 2.5 A. The current in the wir
Tatiana [17]

Answer:

The new current in the wire is 6.3 A.

Explanation:

Given that,

Force in a straight wire, F = 0.023 N

Current in the wire, I = 2.5 A

If new force is, F' = 0.058 N, we need to find the new current.

We know that, magnetic force is given by :

F=ilB\sin\theta

It is clear that force is directly proportional to electric current. So, we can say:

\dfrac{F}{F'}=\dfrac{I}{I'}

I' is new current

I'=\dfrac{IF'}{F}\\\\I'=\dfrac{2.5\times 0.058}{0.023}\\\\I'=6.3\ A

So, the new current in the wire is 6.3 A. Hence, this is the required solution.

3a and c someone please help I really don't understand
earnstyle [38]
F_x=Fcos(a)
F_y=Fsin(a)

1.F_x=166cos(55) 
   F_y=166sin(55)  (55 because of the supplementary angle)

2.F_x= 575cos(-75) (complimentary angle/negative because its under x-axis)
   F_y= 575sin(-75)

The values you get can be negative or positive depending on which side the vector is pointing at.
