Galaxy M33 is classified as a Triangulum normal spiral.
The galaxy M33 is the third largest galaxy in the Local Group after M31 and the Milky Way. The galaxy M33 has a moderate-sized central bulge and two spiral arms that emerge directly out of the bulge and wrap around in rather poorly defined arcs with many cross-connections between the arms.
This spiral galaxy is located in the triangle shaped constellation earning a pet name as triangular galaxy. This galaxy star formation rate is ten times higher than average found in Andromeda galaxy. It has relatively bright apparent. This galaxy was given by Charles Messier and he classified it as Triangulum normal spiral.

Answer:
The spring constant of the spring is 180 N/m.
Explanation:
It is given that,
Mass of the block, m = 0.42 kg
The block is pulled so that the spring stretches for 2.1 cm relative to its unstained length.
When the block is released, it moves with an acceleration of . We need to find the spring constant of the spring. For a block to be in equilibrium, the net force is given by :
k is spring constant of the spring
So, the spring constant of the spring is 180 N/m.
Answer:
Force constant will be 1195.85 N/m
Work done will be 1.6859 J
Explanation:
We have given the force, F = 63.5 N
Spring is stretched by 5.31 cm
So x = 0.0531 m
Force is given , F = 63.5 N
We know that force is given by
So
k = 1195.85 N/m
Now we have to find the work done
We know that work done is given by

- length of muscle fibers,
- maximum stress on each fiber,
- Volume of muscles,
<em>∴Area of the muscle:</em>
a)
Maximum force developed by this muscle:
b)
Force when the muscles are 10% activated:
c)
- contraction in length of muscle,
- time taken for the contraction,
<u>Now, the speed of the muscle:</u>
d)
<u>Maximum force delivered when the muscle fibers are oriented at 15° from the tendons:</u>
