During Mr. Nye's science class, students were expected to identify various substances using physical properties they could easily measure. Mr. Nye gave each of the five groups a green, metal cube and asked them to identify what the cube was made of. Matt's cube, after 5 trials, had an average density of 7.40 g/cm3 . His group's cube was made of A) aluminum. B) gold. C) nickel. D) zinc.

Answers

His group's cube was made of D) zinc. Looking up the density values of each of the choices, it can be seen that zinc has the closest density out of all of them. It's actual density has a value of 7.14 g/cm3. The others have density values that are way too far from the average density of 7.4 g/cm3.

Answer: D.) Zinc

Oversteepened slopes often lead to mass movements becauseA. the angle of their slope is between 50 and 60 degrees.
B. plants cannot grow on them.
C. the angle of their slope is less than 50 degrees.
D. the angle of their slope is greater than 40 degrees.

Answers

The right answer is D.

The slopes are differentiated by the following criteria:

*The inclination;

*The orientation;

*The shape of the slope.

The slope can be measured by degrees or percentages. In the mountains, it is necessary to measure the inclination of a slope by degrees and not by percentages of inclination.

to make the conversion it is necessary to consider that a slope of 45 ° equals a slope of 100%.

D. the angle of their slope is greater than 40 degrees.

Oversteepened slopes often lead to mass movements because the angle of their slope is greater than 40 degrees.

NOT:
A. the angle of their slope is between 50 and 60 degrees.
B. plants cannot grow on them.
C. the angle of their slope is less than 50 degrees.

Heat that flows by conduction is the transfer of thermal energy between substances in contact. What must occur for this to happen? TA B Block A has a higher temperature than block B heat flow The two blocks are the same temperature and heat flow stops Heatis transferred from the wamer block to the cooler block 2012 Encyclopædia Batannlea, Inc. B B heat flow

Answers

Answer:

Heat is transferred from the warmer block to the cooler block

Explanation:

Heat transfer by conduction involves two or more solids. The heat generally moves from a part at higher temperature to one with a lower temperature.

Heat transfer is based on the differences in temperature profile on a body.
When the temperature of the body is the same, heat is not transferred.
The molecules that makes up the hotter body collides with static molecules of the cold one.
Through this, heat is transferred.
