For a person who lives at a latitude of +40 degrees (ukiah for example), when is the sun directly overhead at noon
Nat2105 [25]
The answer is - Never.

40 degrees of latitude, be it on the southern or northern part of the Earth, never gets direct sunlight throughout the year. This is due to the fact that the Earth's inclination is not that big so that the sunlight can fall directly on this latitude, in fact, the inclination of the Earth allows the sunlight to fall directly on the surface only to the lines of 23.5 degrees north and south of the Equator.

A student wants to test the effect of different amounts of caffeine on the heart rate of dogs. Describe the experimental groups
RSB [31]

Answer:

Experimental groups: type of dogs

Dependent variable: hearth rate

Independent variable: the amount of caffeine

The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.

What are some similarities and differences between landslides and creeps? Thank you!
dimulka [17.4K]

Answer:

A mass movement can either be slow or rapid. The slow downward movement of materials in a slope is called creep. This happens when the soil loosens up because of water and burrowing animals. In contrast to this, the rapid movement of large materials in a slope is called landslide.
