Been a while since i've done a problem like this so i might be wrong in the "work" aspect
your system starts with 1200J
you add 700J of heat-
add 700 to 1200
1200+700
and your system does 400J of work
since work is being done by the system, the energy is leaving the system hence you subtract
1900-400
the result is then 1500
ANSWER
The correct answer is D.
EXPLANATION
The y-component of the vector, is the same as the vertical component of the vector.
We can see from the graph that each box in the grid is one unit.
The component of vector a is
We count 4 boxes along the positive y- axis to get the y-component of vector a.
See graph in attachment.
Answer:
The value is
Explanation:
From the question we are told that
The uniform acceleration is
The time considered is
Generally the from kinematic equation we have that
Given that the boat started from rest , the initial velocity is u = 0 m/s
So
=>
