American football uses a field that is 100.0yd long, whereas the a soccer field is 100.0m long. Which field is longer and by how
ioda
I'm using    1m = 3.28084 ft

1 yd = 3 ft

100 yd = 300 ft
100 m = 328.084 ft   the soccer field is longer
                                    by 28.084 ft
                                    =   9.36 yards
                                    =   8.56 meters    

The percentage of  100m  compared to  100 yd  is the same as
the percentage of  1m  compared to  1yd .

           1m / 1yd  =  3.28084 ft / 3 ft

                            =  1.0936

            The soccer field is  9.36%  longer.

There are many muscles in our body. our body uses muscles to move parts of our body. a part that needs to move a lot will have a
alisha [4.7K]

Option b) Stomach is most likely to have the most muscles.

There are five main muscles in stomach pyramidalis, rectus abdominus, external obliques, internal obliques, and transversus abdominis.

Muscles circulate frame parts by contracting after which relaxing. muscular tissues can pull bones, however, they cannot push them to return to their unique role. so they paintings in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.

The muscle groups that circulate our frame elements are called skeletal muscles, and they're a form of striated muscle. We will actively manipulate those with our brains. another sort of striated muscle is those that maintain our hearts pumping, which we are not able to actively control.

Muscles pull at the joints, allowing us to move. a couple of muscular tissues are used for any sort of motion of a bone. Although we are sitting flawlessly nevertheless, muscle tissues at some point in the frame are constantly shifting.

The average radial velocity of galaxies in the Hercules cluster is 10,800 km/s. (a) using H0 = 73 km/s/Mpc, find the distance to
ArbitrLikvidat [17]

Answer:

a) 147.95 Mpc

Explanation:

Using Hubble's formula

v = H_od

where;

v = radical velocity

H_o = Hubble's constant

d = distance

Given that:

The average radial velocity of galaxies in the Hercules cluster v =  10,800 km/s

Also using H_o = 73 km/s/ Mpc ; we  make distance d the subject of the formula:

Then distance d can be written as:

d = \frac{v}{H_o}

d = \frac{10,800  \ km/s}{73 \ km/s/Mpc}

d = 147.95 Mpc

b)

Now, if the Hubble constant had a smaller value, then for a  given velocity the distance to the galaxy will increase because distance d is inversely proportional to H_o

i.e  

d  ∝ \frac{1}{H_0}

Suppose that you measure the length of a spaceship, at rest relative to you, to be 400 m. how long will you measure it to be if
Fantom [35]

Calculate the length of a spaceship as follows:

l = l₀√1 - v²/c²

=(400 m)√1 - (0.75c)2 c²

=264.575m.
