Answer:
yes
Explanation:
objects with constant velocity also have zero net external force. this means the forces on the object are balanced. this mean they are in equilibrium
When an object is above the earth surface gravitational potential energy
i hope this helped :)
Answer:
Ws=8.75 Watts
Explanation:
As per fig. of prob 02.061, it is clear that R5 and R4 are in parallel, its equivalent Resistance will be:
Now, this equivalent Req45 is in series with R3, therefore:
This Req345 is in parallel with R2, i.e
Now this gets in series with R1:
Now, the power delivered Ws is:
Answer:
The elastic potential is 1/2 as much.
Explanation:
The reason I say this is because of you take a new rubber band, after stretching the first time, all the way until it doesn't snap, you stretch it again and there's not as much resistance as when it was new.
I hope this helps.
Answer:
. = 2574.08
Explanation:
given data
magnitude V1 = 80
magnitude V2 = 50
angle a = -37°
solution
= 80 k
= 50 cos{37} i - 50sin{37} k
so that here . is
. = 80 k . ( 50 cos{37} i - 50sin{37} k )
. = 80 k . ( 38.270 i + 32.176 k )
. = 2574.08
