Answer:
Be,Mg,Ca,Sr,Ba.Ra[down the group electronegativity is decreasing]
Explanation:
If a runner completes a 10 km race in 32.5 minutes, his pace or speed can be calculated by the equation:
velocity = distance/time = 10km/32.5 mins = 0.3125 km/min
Convert this value to miles per hour using the conversion factors for minutes to hours and kilometers to miles as requested by the problem. This gives an answer of 11.47 miles per hour.
0.3125 km/min x 60 mins./ 1 hour x 1 mile / 1.609 km = 11.47 miles/hour
Answer:
C. it will have more photosynthesis if it gets more sunlight
Explanation:
The amount of sunlight is crucial for what kind of an ecosystem will develop. This is because the sunlight is what enables the development of the producer communities. The producers use the sunlight in order to perform photosynthesis, so the more sunlight there is, the more photosynthesis they will perform. If there is lot of sunlight, then there will be an abundance of producers in the ecosystem, and since they are the basis of any ecosystem, there will be lot of consumers as well, thus the ecosystem will have an abundance of species from every trophic level.
Ionic compounds contain both cations and anions in a ratio that results in no net electrical charge
