Answer:20 ohms
Explanation:
R1=40 ohms
R2=40 ohms
Let total resistance be R
It is a parallel connection
1/R=1/R1 + 1/R2
1/R=1/40 + 1/40
1/R=(1+1)/40
1/R=2/40
Cross multiply
1x40=2xR
40=2R
Divide both sides by 2
40/2=2R/2
20=R
R=20
Total resistance is 20 ohms
Answer:
upper part second pic
Explanation:
if you observe the trend it increases with each lap and the guy increases the distance he has covered with each lap so distance increases with time
Answer:
6.5 m/s
Explanation:
We are given that
Distance, s=100 m
Initial speed, u=1.4 m/s
Acceleration,
We have to find the final velocity at the end of the 100.0 m.
We know that
Using the formula
Hence, her final velocity at the end of the 100.0 m=6.5 m/s
Answer:
can be called kinetic or potential energy
Explanation:
Answer:If an object's speed changes, or if it changes the direction it's moving in,
then there must be forces acting on it. There is no other way for any of
these things to happen.
Once in a while, there may be a group of forces (two or more) acting on
an object, and the group of forces may turn out to be "balanced". When
that happens, the object's speed will remain constant, and ... if the speed
is not zero ... it will continue moving in a straight line. In that case, it's not
possible to tell by looking at it whether there are any forces acting on it
