Ill mark as brainliest

Elis [28]

Answer: 30Ω

Explanation:

Given that,

Electrical potential (V) = 120V

Current drawn (I) = 4A

Effective resistance of your computer (R) = ?

Recall that voltage is the product of current and resistance

i.e V = I x R

120V = 4A x R

R = 120V / 4A

R = 30Ω (The unit of resistance is ohms, and its symbol is Ω)

Thus, the effective resistance of your computer is 30Ω

The Sun’s surface temperature is about 5800 K and its spectrum peaks at 5000 Å. An O-type star’s surface temperature may be 40,0

vova2212 [387]

Answer:

Part a)

$\lambda_2 = 725 A^o$

Part b)

This range of wavelength exist in the region of X rays

So correct answer will be X Rays

Part c)

No it is not visible because this energy can not travel to large distance

Explanation:

Part a)

As per Wein's law we know that

$\lambda_1T_1 = \lambda_2 T_2$

so we know that

$\lambda_1 = 5000A^o$

$T_1 = 5800 K$

$T_2 = 40,000 K$

now we have

$\lambda_2 = \frac{5000 \times 5800}{40,000}$

$\lambda_2 = 725 A^o$

Part b)

This range of wavelength exist in the region of X rays

So correct answer will be X Rays

Part c)

No it is not visible because this energy can not travel to large distance

A horse pulls on an object with a force of 300 newtons and does 12,000 joules of work. How far was the object moved?

liubo4ka [24]

We know, work done = Force * displacement
Here, w = 12,000 J
f = 300 N

Substitute their values into the expression:
12,000 = 300 * d
d = 12,000 / 300
d = 120/3
d = 40 m

In short, Your Answer would be 40 meters

Hope this helps!
