What is the total current in the circuit? (must include unit - A) REWARD = BRAINLEST

Aleksandr-060686 [28]

Answer:6amperes

Explanation:

1/R=1/40 + 1/40

1/R=2/40

Cross multiplying we get

2R=40

Divide both sides by 2

2R/2 =40/2

R=20ohms

Current=voltage ➗ resistance

Current=120 ➗ 20

Current =6amperes

How much work was done to accelerate a 2.2 kg object from rest to 26m/s?

Makovka662 [10]

Answer:

Explanation:

work done = change in kinetic energy, assuming there are no energy losses.

work done = 1/2 × m × change in v^2

= 1/2 × 2.2 × ( 26^2 - 0^2)

= 1/2 × 2.2 × 676

= 743.6 joules

A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvat

madam [21]

Answer:

12 cm

Explanation:

We shall use Lens makers formula here which is as follows

$\frac{1}{F} =(\mu-1) (\frac{1}{R_1} -\frac{1}{R_2})$

Put μ = 1.5 , R₁ = 10 cm ,R₂ = - 15 cm ( according to sign convention )

$\frac{1}{F} =(1.5-1) (\frac{1}{10} -\frac{1}{-15})$

= .5 x ( 15 + 10 ) / 15 x 10

= $\frac{25}{2\times10\times15}$

F = 12 cm
