Answer:
positive
Explanation:
No. of positive charge= 7
No.of negative charge = 6
so 7 - 6 = 1 positive charge
It should be satellites but I’m not sure
The glider collides elastically an another glider at rest, in this case we have the coservation of quantity of movement
m1 v1 + m2 v2 = m1V1 + m2 V2
v is the velocity before the shock, V the velocity after the shock
m1=0.22
v1=0.60m/s
m2=0.44
V1=-0.20m/s
remark that <span>0.44 kg glider is initially at rest, so v2= 0
the equation above can be written </span><span>m1 v1 = m1V1 + m2 V2 ( because v2=0 at rest)
</span><span>m1 v1 = m1V1 + m2 V2 implies V2= (m1v1 -m1V1) / m2
</span>
V2=0.22x0.60 -0.22x (-0.20) ] / 0.44= 0.4m/s
Answer:
8 minutes
Explanation:
Part of the question is missing. Complete question is:
<em>Simpson drives his car 144 km with an average velocity of 24 m/s toward the east. How much time would Simpson save by increasing his average velocity to 26m/s East?</em>
Solution:
First of all, we have to calculate the time it takes for Simpson to complete the drive moving at the initial velocity, 24 m/s. We can use the formula:
where
is the displacement
is the velocity
Substituting,
While driving at 26 m/s, the time taken will be
So, Simpson will save 8 minutes.
