Physics Problems (Urgent!)?

Question

Convert:

1. 2.5 days to seconds

2. 35 km to millimeters

3. 43 cm to kilometers

4. 22 mg to kilograms

5. 671 kg to micrograms

6. 8.76 x 10^7 mW to gigawatts

7. 1.753 x 10^-13 seconds to picoseconds

Answer 1

1. 2.5 * 24 * 3600 = 2,16,000 seconds = 2.16 * 10^5 seconds

2. 35 * 10^6 miilimeters = 3.5 * 10^7 milimeters

3. 43 cm = 43 * 10^-2 m = 43 * 10^-5 km = 4.3 * 10^-4 km

4. 22 mg = 22 * 10^-6 kg = 2.2 * 10^-5 kg

5. 671 kg = 671 * 10^3 g = 673 * 10^9 micrograms = 6.73 * 10^11 micrograms

6. 8.76 * 10^7 mW = 8.76 * 10^4 W = 8.76 * 10^-5 gigawatts

7. 1.753 x 10^-13 = 1.753 * 10^-1 picoseconds = 0.1753 picoseconds

Ans:

1. 2.16 * 10^5 seconds

2. 3.5 * 10^7 milimeters

3. 4.3 * 10^-4 km

4. 2.2 * 10^-5 kg

5. 6.73 * 10^11 micrograms

6. 8.76 * 10^-5 gigawatts

7. 0.1753 picoseconds

You got the answers. But how will it help you? In exam, you have to answer yourself.

Answer 2

Type these in on the Google home page, most of the time it will calculate it and give you the answer.  

Answer 3

If you can't do this you don't need to be enrolled in Physics.

Answer 4

may I ask why this is urgent?

Answer 5

Get a brain!

Answer 6

stop trying to cheat figure it out stupid

Answer 7

www.onlineconversion.com  it's a really good website
