Answer:
110 yds
Explanation:
Well if 55 yards is 1/2 of the field then 2 x 55 = 110 yards is total field length
Answer:
-0.7 m/sec
Explanation:
Mass of first block = m1 =3.0 kg
Mass of second block = m2= 5.0 kg
Velocity of first block = V1= 1.2 m/s
Velocity of second block = V2 = ?
Momentum of Center of mass MVcom is sum of both blocks momentum and is given by
MVcom= m1v1+m2v2
Where
M= mass of center of mass
Vcom= Velocity of center of mass=0 m/s (because center of mass is at rest , so Vcom = 0 m.sec)
Putting values, we get;
0= 3×1.2+5v2
==> v2= 3.6/5= - 0.7 m/s
-ve sign indicates that block 2 is moving in opposite direction of block 1
Answer:
it will be 1/√2 of its original period.
Explanation:
Answer:
ntergalactic space takes up most of the volume of the universe, but even galaxies and star systems consist almost entirely of empty space.
Explanation:
so to be exact galixes do make up most of the volume of space because galaxies are what make up space!
Answer:
Answer:
118.4 N
Explanation:
weight of chair, mg = 95 N
Push, F = 39 N
Ф = 37 ° below x axis
Let n be the normal force.
So, by using the diagram and resolve the components of Force F.
n = mg + F SinФ
n = 95 + 39 Sin 37°
n = 95 + 39 x 0.6
n = 118.4 N
