Explanation:
The magnetic needle of a compass lines up with Earth's magnetic poles.
58 the number of protons are the same as your atomic number<span />
There are two ways to solve this. The longer way is to use those equations to calculate numbers for total distance.
The easier way is to find the area under the graph. That's right, AREA UNDER VELOCITY-TIME graph is the TOTAL DISTANCE travelled!
it's a shortcut.
Let's split up the area into a triangle and rectangle:
Triangle = 0.5(4-0)(10-0) = 20 m
Rectangle = (6-4)(10-0) = 20 m
Total distance = 40 m!
Answer:2155 J
Explanation:
Given
Change in Internal energy i.e. decrease in Internal Energy
Heat added to system
According First law for a system
Thus 2155 J of work is done by system
