Some benefits to solar power:
Isolated power is very abundant on earth.
Is very sustainable (5 billion years of good use)
Eco friendly excluding panel production.
Some disadvantages:
Very expensive to set up
Takes up a lot of space per person
Requires exotic materials to construct
Energy storage is difficult with solar cells compared to fossil fuels.

a straight wire that is 0.60m long and carrying a current of 2.0a is placed at an angle with respect to a magnetic field of stre

Rashid [163]

Answer:

The angle is $\theta = 30^o$

Explanation:

From the question we are told that

The length of the wire is $l = 0.60 \ m$

The current is $I = 2.0 \ A$

The magnetic field strength is $B = 0.30 \ T$

The magnitude of the magnetic force is $F _b = 0.18 \ N$

Generally the magnetic force exerted on the wire is mathematically represented as

$F_b = I * l * B * sin \theta$

Making $\theta$ the subject

$\theta =sin^{-1} [ \frac{ F_b }{I * l * B } ]$

substituting values

$\theta =sin^{-1} [ \frac{ 0.18 }{ 2.0 * 0.6 * 0.3 } ]$

$\theta = 30^o$

Force Problem: Four concurrent forces are applied to a 5 Kg mass: 50 N North, 25 N East, 35 N South, and 35 N West.

Kaylis [27]

A) Net horizontal force:
Fx= -35 + 25 + -10N

Net vertical force
Fy= 50 - 35 = 15N

Net force
F^2 = fX^2 +Fy^2
F= 18N

B.) Acceleration of system
a=18/5=3.6m/s^2

C). Equilibriant force must be equal to the net force above
F1= 18N

D.) Acceleration becomes half
a1= a/2 =1.8m/s^2

E.) Equilibrant force also doubles
F" = 2F' = 36N

Answer:

Explanation:

These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.

just olya [345]

Answer:

1.99 parsecs.

Explanation:

We have been given that the most recently discovered system close to Earth is a pair of brown dwarfs known as Luhman 16. It has a distance of 6.5 light-years.

We know that one light year equals to 0.306601 parsecs. To convert 6.5 light-years to parsecs, we will multiply 0.306601 by 6.5.

$6.5\text{ Light-years}=6.5\times 0.306601\text{ Parsecs}$

$6.5\text{ Light-years}=1.9929065\text{ Parsecs}$

$6.5\text{ Light-years}\approx 1.99\text{ Parsecs}$

Therefore, Luhman 16 is approximately 1.99 parsecs away from the Earth.
