Scientific notation is the writing of a number as a decimal number with one digit left of the decimal and all the other digits to the right, and then the power of ten appropriate to expressing that number. Here we have 375,000 for our number. First we need to figure out where the decimal is going to be. It will, per the rule, be between the 3 and the 7. That puts it in a place where only the 3 is to the left of the decimal. (One digit, per the rule.) To get it there, we need to move the decimal to the left by five places. When we move the decimal to the left, we have to multiply by a positive power of 10 to correctly express the number. 375,000 = 3.75 x 105 for your answer in scientific notation.
(450,000 meters) x (1 second/120 meters) = 3,750 seconds( 1hour 2minutes 30seconds )
No.
1 km per second is defined as equal to 1000 meters per second. Therefore, a speed of 15 meters per second is 15/1000 km per second or 0.015 km per second.
Images per second and frames per second are both the same. They describe the video image that is stored.
It is 22 fs-1 (assuming that fs stands for feet per second.
1.86 x 10^5 miles per second (approximate)
It is about: 1.86*10^5 miles per second
The speed of light is approximately 3 x 10^8 meters per second. To convert this to nanometers per second, we multiply by 1 billion (10^9) to get 3 x 10^17 nanometers per second.
120 miles per second equates to 633,600 feet per second.
120 feet per second = 81.8 mph
120 meters per second is approximately equal to 393.7 feet per second.
120 feet per second = 819/11 miles per hour
Engineering notation changes every factor of 1000, so it corresponds to the SI prefixes (and names of large numbers). So 3 x 10^8 m/s becomes 300 x 10^6 m/s, or 300 megameters per second (or 300 million meters per second).
9.8 x 108
120 km per hour = 120,000 meters per hour = 331/3 meters per second
8 quarts per second.
