Answer:
<em>D. 20 N</em>
Explanation:
<em>Force</em><em> </em><em>=</em><em> </em><em>mass(</em><em>m)</em><em> </em><em>×</em><em> </em><em>acceleration</em><em> due</em><em> to</em><em> </em><em>gravity (</em><em>g)</em>
<em>Force </em><em>=</em><em> </em><em>2</em><em>k</em><em>g</em><em> </em><em>×</em><em> </em><em>1</em><em>0</em><em>m</em><em>/</em><em>s²</em>
<em>Force</em><em> </em><em>=</em><em> </em><em>2</em><em>0</em><em>N</em>
Answer:
F4.0
Explanation:
To obtain a shutter speed of 1/1000 s to avoid any blur motion the f-number should be changed to F4.0 because the light intensity goes up by a factor of 2 when the f-number is decreased by the square root of 2.
Russia and the United States sign the Moscow Treaty.
The correct answer to fill
in the blank would be:
“a barrier island”
Barrier islands are
coastal landforms and a category of dune system that are remarkably even or
lumpy areas of sand that was formed by wave and tidal actions that are parallel
to the mainland coast. Due to this feature, there are no enough sand blockades
to minimize the destruction by Hurricane Sandy.
Answer:
This values shows a right angle triangle
Explanation:
Given;
a vector 4.0 km due East
a 3.0 km due north
the resultant vector is 5.0 km
The resultant vector can be obtained by Pythagoras theorem if the vectors form a right angle triangle.
R² = 4² + 3²
R² = 16 + 9
R² = 25
R = √25
R = 5 km (right angle triangle proved)
Therefore, this values shows a right angle triangle
