Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 mph to a mass of 1 kg |
|
1 m/s to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
|
1 m/s2 to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
212°F is how many °C?
0 |
|
\(135 {5 \over 9}\) |
|
100 |
|
-100 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
In the water cycle, infiltration is most closely related to:
oceans |
|
water table |
|
runoff |
|
rivers |
The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.
Which of the following is not a terrestrial planet?
Venus |
|
Mercury |
|
Jupiter |
|
Earth |
The four planets closest to the Sun (Mercury, Venus, Earth, and Mars) are called terrestrial (Earth-like) planets because, like the Earth, they're solid with inner metal cores covered by rocky surfaces.
In the classification of life, which of the following is not a domain?
archaea |
|
animalia |
|
bacteria |
|
eukaryota |
The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
