A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
Explanation:
The most likely observation the student will record is that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.
This phenomenon between the differences in land and water temperature causes land sea breeze to occur.
- Water has a very high specific heat capacity.
- This implies it takes more heat to cause a monumental increase in its temperature.
- It is expected that the student will observe that the air over the lake body will reach its highest temperature later in the day. It would have gotten heated with time.
A body such as water in a lake with a high specific heat capacity stays warm for a longer period of time compared to other substances.
Metals do not have high specific heat capacity and would not stay warm for long. They quickly lose heat.

Answer:
The force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second is 12 newton.
Explanation:
- According to Newton's second law based motion "the moving object's acceleration is based upon two terms - one is the total force acting upon that object and the other one is the net mass of the object."
- In mathematical term, F=ma. where F= force, m= mass, a= acceleration.
- So, by performing the calculation,
- 12N force will move the boy along with the wheel chair.
The options provided for the question above are as follows:
A. Respiratory tract illnesses
B. Skin infection
C. Acute infectious diaherea
D. Intestinal infections.
The correction option is A.
Respiratory tract illnesses account for the majority of sickness that occur in child care settings. Such infection include those that affect the lower and the upper respiratory tracts; examples include: otitis media, sinusitis, bronchiolitis, pneumonia, etc. Children who attend out of home child care has greater risk of contacting these diseases.
Answer:
Ralph is looking at a vein (likely a muscular vein).
Explanation:
Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves. This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.
Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.
