Answer:

I = 2 [amp]

Explanation:

To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of the current by the resistance.

The resistances in the diagram are connected in series, in this way the total resistance will be equal to the algebraic sum of the resistivity.

R = R1 + R2

R = 3 + 2

R = 5 [ohm]

Now, using ohm's law we have:

V = I*R

where:

V = voltage = 10 [V]

I = current [amp]

R = resistance = 5 [ohm]

I = V/R

I = 10/5

I = 2 [amp]

Which of the following is not in our sun's future?

fenix001 [56]

The answer would not be A, because if the sun converts into a giant, the star will eventually become a white dwarf due to the fact it was previously a giant. Thus the answer would be B, since the sun does not become a supergiant.

Four uniform spheres, with masses mA = 200 kg, mB = 250 kg, mC = 1700 kg, and mD = 100 kg, have (x, y) coordinates of (0, 50 cm)

rusak2 [61]

Answer:

$F_2=2.43\times10^{-19}\ N$

$\theta=21.496^{\circ}$ in the anticlockwise direction from the positive x- axis.

Explanation:

Given are the masses of various spheres with their names in subscript:

$m_A=200\ kg$

$m_B=250\ kg$

$m_C=1700\ kg$

$m_D=100\ kg$

Now their respective coordinate positions (in cm) are as given below:

$P_A=(0,50)$

$P_B=(0,0)$

$P_C=(-80,0)$

$P_D=(40,0)$

Now force on B due to A:

$F_{BA}=G\times \frac{200\times 250}{50^2}$

$F_{BA}=20G\ N$

Now force on B due to C:

$F_{BC}=G\times \frac{1700\times 250}{80^2}$

$F_{BC}=66.406G\ N$

Now force on B due to D:

$F_{BD}=G\times \frac{100\times 250}{40^2}$

$F_{BD}=15.625G\ N$

We observe that the forces due to masses C&D act opposite in direction.

So, the net force in the x-direction:

$F_x=F_{BC}-F_{BD}$

$F_x=66.406G-15.625G$

$F_x=50.781G\ N$ in the positive x-direction

We have only one force in y-direction due to mass A.

So,

$F_y=20G\ N$ in the positive y-direction.

Now the net force:

$F_2=\sqrt{F_y^2+F_x^2}$

$F_2=\sqrt{(20G)^2+(50.781G)^2}$

$F_2=54.5776G^2\ N$

$F_2=2.43\times10^{-19}\ N$

Now the direction of this force with respect to x-axis:

$tan\ \theta=\frac{F_y}{F_x}$

$tan\ \theta=\frac{20G}{50.781G}$

$\theta=21.496^{\circ}$ in the anticlockwise direction from the positive x- axis.
