Aspeed of limit of 100 kilometers per hour is approximately equal to 62 miles per hour predict the following measures round your answers to the nearest whole number a. a speed limit in mph for a speed limit of 75 kph b. a speed limit in kph for a speed limit of 20 mph

a. 46.5 mph

b. 32.3 kph

Step-by-step explanation:

If the speed limit is 100 km/hour we and this equals 62 mile per hour we can determine how many kilometers is in miles and vice versa:

WE can do this as:

Therefore the 0.62 miles per kilometer

a) For 75 kph we can use the conversion we determine to convert to miles per hour:

It takes a speed limit of 46.5 mph for a 75 kph limit

b) For 20 mph we can use the conversion we determine to convert to kilometers per hour:

It takes a speed limit of 32.3 kph for a 20 mph limit

okay, if you need all you need to do is ask, and i'll do my best to assist you.

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
