Average speed of the trip = 52 km/hr

<h3>Further explanation  </h3>

Distance is the length traveled by an object within a certain of time .

Average speed = total distance/total amount of  time ,

Can be formulated :

\tt S(speed)=\dfrac{D}{T}

Total distance travelled : 1560 km

Total time : 8 hr + 12 hr + 10 hr = 30 hr

\tt avg.speed=\dfrac{tot~D}{tot~T}\\\\avg.speed=\dfrac{1560}{30}\\\\avg.speed=52~km/hr

Iodine 131, cesium 137, and strontium 90 are all considered isotopes. What are isotopes?
Nitella [24]

Answer:

Isotopes are variants of an element, where the number of neutrons is different but its number of protons stay the same.

Explanation:

If the number of protons had changed then it would just be a different element.

Electron number changing simply adds charge to the atom, and doesn't change it or anything.

If 2,035 cal of heat is added to a 500.0 g sample of water at 35.0°C, what is the final
Lynna [10]

Answer:

39.1 °C

Explanation:

Recall the equation for specific heat:

q=mc \Delta T\\

Where q is the heat, m is the mass, c is the specific heat of the substance (in this case water), and delta T is the change in temperature.

You should know that the specific heat of water is 1 cal/g/C.

Using the information in the question:

2035=500(1)(T-35)\\2035=500T-17500\\500T=19535\\T=39.07

The final temperature is about 39.1 °C.

Klio2033 [76]

Answer:

Explanation:

This type of experiment was carried out in 1960s on rodents, it was partially successful but was perceived impractical and dangerous for humans,it is possible theoretically.

Oxygen is broken down or dissolves in a thin film of fluid in the alveoli, surprisingly in normal breathing liquid composed of dissolved oxygen is involved. Evidently respiratory gas must be able to dissolve in this liquid and in concentration required to keep the partial pressure necessary to power diffusion.
