Assume <em>R</em> is measured in meters (m) and <em>M</em> in kilograms (kg). Then
<em>R</em> ² / (<em>GM</em>) = [m]² / ([N•m²/kg²] [kg]) = m•kg / N = m•kg / (kg•m/s²) = s²
so <em>t</em> ² is indeed proportional to <em>R</em> ²/(<em>GM</em>).
Answer:
Many tree seedlings crowd the open space and attempt to grow in the sunlight.
Answer:
Efficiency = 5%
Explanation:
Given that,
Supplies energy to the bulb = 100 J
Transferred energy by the bulb = 5 J
We need to find the efficiency of the bulb. It can be given by "
So, the efficiency of the bulb is 5%.
Average speed = (total distance covered) / (time to cover the distance)
Total distance = 69 km + 51 km = 120 km
Total time = 3 hrs + 2 hrs = 5 hrs
Average speed = (120 km) / (5 hrs) = 24 km/hr
Mars Global Surveyors (MGS) and later orbiters found the following minerals on the Martian surface;
- Carbonate
- Sulfates
- Iron oxide
The Mars Global Surveyors (MGS) and later orbiters suggest that the Martian crust contains a higher percentage of volatile elements such as Sulphur and chlorine than the Earth's crust does.
These scientists also conclude that the most abundant chemical elements in the Martian crust are those found in Igneous rock.
These elements include the following;
- Silicon,
- Oxygen,
- Iron,
- Magnesium,
- Aluminum,
- Calcium, and
- Potassium.
They also, suggest that hydrogen is found in ice (water) while carbon is found in carbon dioxide and carbonates.
From the given options the minerals found in Martian surface include;
- Phyllosilicates ------ these are sheet of silicate minerals
- Carbonate
- Sulfates
- iron oxide
