Alejandro wants to find the speed of his car in meters per second. His car traveled 50 cm. It took 5 seconds to travel 50 cm. How fast did his car go?

0.1m/s

Explanation:

Speed can be calculated using the formula;

Speed (m/s) = distance (m) ÷ time (s)

According to the information provided in this question, Alejandro's car travels 50cm in 5seconds i.e. the distance traveled is 50cm and the time is 5s.

However, the question requires the distance to be in metres (m). We, therefore, need to convert 50cm to m by dividing by 100.

100cm = 1m

50cm = 50/100

= 0.5metres.

Speed = 0.5/5

Speed = 0.1m/s.

The car travels as fast as 0.1m/s.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
