Use the fact that the speed of light in a vacuum is about 3.00 103 meters per second to determine how many kilometers a pulse from a laser beam travels in exactly 8 hours?
The speed of light in a vacuum is 3.00 x 10^8 m/s. To convert this to kilometers per second, divide by 1000 to get 3.00 x 10^5 km/s. In 8 hours, there are 8 x 3600 = 28800 seconds. The distance the pulse travels is speed x time, so it would be 3.00 x 10^5 km/s x 28800 s = 8.64 x 10^9 km.
What is the wavelength of electromagnetic radiation having a frequency of 5.00X10 12 Hz?
Frequency of electromagnetic radiation = (speed of light) / (wavelength) Speed of light in vacuum = 300,000,000 meters/sec (rounded) Frequency = (300,000,000 meters/sec) / (5 x 10-6 cm) = (3 x 108 m/s) / (5 x 10-8 m) = 0.6 x 1016 = 6 x 1015 Hz.
What is the speed of a wave with a wavelength of 0.5 m and a frequency of 20 Hz?
The product of the two. Since hertz is equivalent to (1/sec), the answer of course is in meters/second.
How far does light travel in 50 microseconds?
Speed of light in vacuum = 300,000,000 meters/sec (rounded) (3 x 108 m / sec) x (5 x 10-5 sec) = 15 x 103 meters = 15 km = approx. 9.3 miles
What is the acceleration of car that increase its speed by 10 milessec after 30 seconds if the initial velocity was 20 milessec?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the final velocity is 20+10 = 30 miles/sec, the initial velocity is 20 miles/sec, and the time is 30 seconds. So, the acceleration of the car is (30 - 20) / 30 = 0.33 miles/sec^2.

If an electron travels 2.42 x 10 to the 8meters in 3.00 seconds what is the speed?
2.42 * 10^ 8 m in 3 seconds = (2.42 / 3.00) * 10^8 m / sec =0.806667 * 10^8 m / sec = 8.06667 * 10^7 m / sec
A car accelarates uniformly from 36kmhr to 54kmhr in 10s find accelaration and distance traveled by the car during this interval of time?
Acceleration = (change in speed) / (change in time) = [ (54 - 36) km/hr ] / (10 sec) = (18 km/hr) /(10 sec) = (1.8 km/hr-sec) x (3,600 sec / hr) = (1.8 x 3,600) (km - sec / hr2 - sec) = 6,480 km / hr2 Average speed during the 10 seconds = (36 + 54) / 2 = 90/2 = 45 km/hr Distance = (average speed) x (time) = (45 km/hr) x (10 sec) x (1 hr / 3,600 sec) = (45 x 10 / 3,600) (km - sec - hr / hr - sec) = 0.125 km = 125 meters
