Because blocks 2 and 3 have sides with unequal forces while block 1 doesnt. Plz drop a follow if this helps! ❤
Constellations are based off of many Greek and Roman fables. Many of their gods and beliefs are pictured in the stars, which is where we get most of our constellations. Hope this helps!
Hi! I'm a few days late since I just saw this question just now, but I'll answer anyway.
Answer:
When an unbalanced force acts on a moving object, the velocity of the object will change. Change in velocity means a change in speed, direction, or both. For example, if you kick a soccer ball and it moves from one place to another, it means that unbalanced forces are acting upon it. The ball moves from one place to another after kicking it so the position changed.
Answer:
Explanation:
First we must find the real power that is dissipating for each of the two cases, this is achieved by multiplying the nominal power by the efficiency
P=Poη
P=power
Po=nominal power
η=efficiency
POWER NUMBER 1
P1=400*0.89=356W
POWER NUMBER 2
P2=400*0.94=376W
then we find the power change by subtracting both results
ΔP=P2-P1=376-356=20W
always ensure that the efficiency in any system is maximized, because it is always required that the amount of energy delivered by the system is maximum with the same input power.
