Calculate the speed for a car that went a distance of 125<br> kilometers in 2 hours tiine.
Leno4ka [110]

Answer:

62.5 km/hr

Explanation:

Speed can be found by dividing the distance by the time.

s=d/t

We know the car travelled a distance of 125 kilometers in 2 hours. Therefore:

• d=125 km

• t= 2 hr

Substitute the values into the formula.

s= 125 km/ 2 hr

Divide

s= 62.5 km/ hr

The speed of the car is 62.5 kilometers per hour.

Isotopes of elements have different:
Ray Of Light [21]
<span>Isotopes are atoms of the same element with the same number of protons and same number of electrons but with <span>different number of neutrons. They differ in the number of neutrons that is why they also differ in mass numbers. Since they have the same number of protons, they have the same atomic number. 
For instance, when the nucleus of the isotope with a 68.926 amu, there are 30 protons and 39 neutrons in the nucleus. The best example for this is Zn (zinc-69 isotope) and Ga (gallium-69 isotope) which has 68.926 amu and 68.925 amu respectively.
