In the list below, there is a group of two numbers with the same order of magnitude. No other numbers in the list have this same order of magnitude. Select both of these numbers. 748
82341
3984
5421
17354
374
4287
10751

numbers with order of magnitude 10³

748, 3984, 4287

numbers with order of magnitude 10⁴

5421, 17354, 10751

Explanation:

The order of magnitude is a way to give the values of a quantity when you do not have a high pressure, the way to find this order of magnitude is to take the number to scientific notation and then approximate the integer to 10 if it is greater than or equal to five or 1 if less than 5

Let's apply this to each of the numbers on the list

748 = 7.48 10² = 10 10² = 10³

order of magnitude 10³

82341 = 8.2341 104 = 10 10⁴

order of magnitude 10⁵

3984 = 3,984 10 3 = 10⁰ 10³

order of magnitude 10³

5421 = 5,421 103 = 10 10³

order of magnitude 10⁴

17354 = 1.7354 104 = 10⁰ 10⁴

order of magnitude 10⁴

374 = 3.74 102 = 1  10²

order of magnitude 10²

4287 = 4,287 103 = 1 10³

order magnitude 10³

10751 = 1.0751 104 = 1  10⁴

order of magnitude 10⁴

numbers with order of magnitude 10³

748, 3984, 4287

numbers with order of magnitude 10⁴

5421, 17354, 10751

i was thinking more like reflects green light, just not sure

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
