Well the formula is V= I x R. (Voltage)=(Amps)x(Ohms)

So just plug it in! lol

15 x 8 =120

Hope this helps!

Which of the following is the most effective way for humans to reduce biodiversity loss?

ANTONII [103]

Answer:

Creating large preserves in biodiversity hotspots

Explanation:

In order to preserve the biodiversity hotspots, humans must create biodiversity hotspots which are regions that will nurture, preserve and protect the species from the danger of going extinct in the wild or being hunted by other predators or men.

There will help protect them from dangers and improve the biodiversity of the planet. It will add to the ecological productivity of the environment.

A 900 kg car runs into a 70 kg deer at 28 m/s. If the car transfers all of its momentum to the deer, how fast does the deer go f

Alex

Answer:

Mc = 900 Kg

Uc = 28 ms^-1

Md = 70 Kg

Ud = 0

We want Vd

Vc = Vd

This situation is elastic momentum

$m _{c}u _{c}+ m _{d}u _{d} = m _{c}v _{c} + m _ dv _{d} \\ (900 \times 28) + (70 \times 0) = (900 \times v _{d} ) + (70 \times v _{d}) \\ 25200 = (900 + 70)v _{d} \\ 25200 = 970v _{d} \\ v _{d} = \frac{25200}{970} \\ v _{d} = 26 \: m {s}^{ - 1}$

Pavel [41]

He could theoretically push the gold brick away from himself, and due to Newton's 3rd law (Every action has an equal and opposite reaction), the same amount of force would recoil back at him from the gold brick. As a result, he will move in the opposite direction from the gold brick, and since it as an ideal frozen lake (meaning there is no friction present), he will keep going until he reaches the edge of the lake.

And I don't know if he's still a fool. That's up to you.

Two ships leave a harbor at the same time. One ship travels on a bearing S 13 degrees W at 16 miles per hour. The other ship tra

Artemon [7]

Answer:

47 miles

Explanation:

From the diagrammatic representation below;we can observe the illustration of the question.

after two hours;

The first ship = 16 miles per hour × 2 hours = 32 hours

the second ship = 11 miles per hour × 2 hours = 22 hours

to solve for ΔQPR in the diagram; we have;

∠ P = 13° + (2nd quadrant) + 15°

∠ P = 13° + 90° + 15°

∠ P = 118°

To solve for the distance apart the two ship, we can see from the diagram that it is "p". So, using cosine rule; we have:

p² = q² + r² - 2qr Cos P

p² = 22² + 32² - 2(22)(32) Cos 118°

p² = 484 + 1024 - (1408) (-0.4695)

p² = 1508 + 661.056

p² = 2169.056

p = $\sqrt{2169.056}$

p = 46.5731252

p ≅ 47 miles

∴ The ships will be 47 miles far apart after 2 hours.
