A globular cluster is a collection of stars in the form of a sphere that orbits a galactic core. Global clusters are generally tightly bound by gravity, making the stellar density higher toward the center, and giving them their spherical shapes. Globular clusters are usually found in the halo of a galaxy.
The fact that the gravitational pull of a globular cluster is rather weak means that a single supernova explosion can blow the interstellar gas out of a globular cluster. This would mean that the gas left is not dense enough to form new stars. After the first generation, globular clusters cease to form new stars because they lack material due to their deficiency in heavy elements.
Pia spend about eight to ten dollars a week in the grocery for vegetables and fruits. If all amount for the next three weeks would be added it would be twenty-four to thirty dollars. First in order to get the amount per week it would be 20 percent multiply the total amount which is 40 to 50 dollars. Then in order to get the entire expenses for the three weeks on vegetables and fruits you can multiply the amount you get in the first process to three times.
Answer:
Explanation:
Given that,
The temperature of the surface = 90°F = 305.372 K
We need to find the wavelength of maximum energy emission of your body. According to the Wien's law,
Put all the values,
So, the required wavelength is equal to 
.
