Answer:
0.00789pa
Explanation:
since pressure=force/area
=400/0.5
=800N/m2
1.013*10^5N/m2=1pascal
800N/m2=xpascal
therefore it becomes,800/1.013*10^5
=0.00789pascal
Indeed because some leave headlights off and ignore that fact since there are street lights around.
A) <span>Ivan does work when he lifts the basket
B) Work = Force * displacement
W = 20 * 2
W = 40 Joules
So, The Amount of work he does is 40 Joules

Answer:C..net work done on the object.
Explanation:
Answer:
the potential energy is 114 J.
Explanation:
Given;
total mechanical energy, E = 400 J
kinetic energy, K.E = 286 J
The potential energy is calculated as follows;
E = K.E + P.E
where;
P.E is the potential energy
P.E = E - K.E
P.E = 400 J - 286 J
P.E = 114 J
Therefore, the potential energy is 114 J.
