Fill in the blank for a school project, robert records the motion of a snail and plots a position-time graph of the data. from the graph, the speed of the snail in the first 20 seconds is centimeter/second. after that, the snail remains in the same place for seconds.

From the graph, the speed of the snail in the first 20 seconds is

1  centimeter/second.

After that, the snail remains in the same place for 50  seconds.

As we know  

Speed= distance covered / unit time

So putting the values in the above equation we get

Speed= 20 cm/20 sec

Speed= 1 cm/s ec

After that the snail remained still for 50 cm because the line is straight from 20 seconds to 70 seconds as the distance is not changing as shown in the graph so 70 sec -50 sec= 20 sec  

1 cm/sec and 50sec

Explanation:

i got this question on a test and those were the right answers

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
