Answer:
<h2>
650W/m²</h2>
Explanation:
Intensity of the sunlight is expressed as I = Power/cross sectional area. It is measured in W/m²
Given parameters
Power rating = 6.50Watts
Cross sectional area = 100cm²
Before we calculate the intensity, we need to convert the area to m² first.
100cm² = 10cm * 10cm
SInce 100cm = 1m
10cm = (10/100)m
10cm = 0.1m
100cm² = 0.1m * 0.1m = 0.01m²
Area (in m²) = 0.01m²
Required
Intensity of the sunlight I
I = P/A
I = 6.5/0.01
I = 650W/m²
Hence, the intensity of the sunlight in W/m² is 650W/m²
D. They are heterotrophs that digest food internally.

61.0168 g/mol Explanation:
<h2>Answer: A solid mass</h2>
The first atomic model was the one proposed by Jhon Dalton, according to which it is postulated that:
"Matter is made up of <u>indivisible, indestructible and extremely small particles</u> called atoms."
That is, <em>the atom is a </em><u><em>solid and indivisible mass</em></u><em>.</em>
However, over time <u>some limitations were found in Dalton's atomic model </u>and was replaced by the Thomson's atomic model, then by Rutherford's, Bohr's, Sommerfield's, and finally Shrodinger's.
Currently it is known that each atom is composed of a nucleus and one or more electrons attached to the nucleus, which is composed of one or more protons and typically a similar number of neutrons.
In addition, the atomic nucleus is the central part of the atom and concentrates most of the total mass of the atom.
Therefore, the correct option is A.
The speed with which Jennifer climb up the tree is 0.45 m/s
The distance is 10m
Time is 22 seconds
Required speed is 10/22=0.45 m/s
- Distance is the total length travelled by an object.
- Speed is distance upon time.
- It is a scalar quantity and doesn't has magnitude and direction.
- Distance traveled is the total length of the path traveled between two positions
- Distance is the total movement of an object without any regard to direction.
- Distance is the total movement of an object without any regard to direction.
