A horse runs 1 km in 15 s. What is the average speed
Reptile [31]

The average speed of the horse for the entire motion is 66.67 m/s.

The given parameters;

  • <em>distance traveled by the horse, d = 1 km = 1,000 m</em>
  • <em>time of motion of the horse, t = 15 s</em>

The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.

The average speed of the horse is calculated as follows;

average\ speed = \frac{distance}{time} \\\\average\ speed =  \frac{1000 \ m}{15 \ s} = 66.67 \ m/s

Thus, the average speed of the horse for the entire motion is 66.67 m/s.

8.00*10^-5 mol was diluted to 500ml what is the concentration in Mol/L?
OLEGan [10]
Make sure all units are consistent. Convert ml to L first. (500ml = 0.5L). Then divide the mole by the volume which would result to 1.6*10^-4mol/L. This can also be expressed as interms of molarity (M). 1 M = 1 mol/L hence the final answer is <span>1.6*10^-4 M. </span>

How many neutrons does an element have if its atomic number is 55 and its mass number is 150?
Lynna [10]
With an atomic number of 55, that means there are 55 protons. Because electrons do not count towards atomic weight, the element would have 150-55 neutrons. So, 95 neutrons.
