Globular clusters are nearly spherical groups of about 10,000 to 1 million stars. A typical galaxy may contain up to a few hundred globular clusters; our galaxy, the Milky Way, has somewhere between 125 and 200 globular clusters orbiting the galactic center.

Given the data from the question, the bullet's temperature increases by 85.5 °C
How to determine the kinetic energy
- Mass (m) = 5 g = 5 / 1000 = 0.005 g
- Velocity (v) = 210 m/s
- Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 0.005 × 210²
KE = 110.25 J
How to determine the increase in temperature
- Kinetic energy (KE) = 110.25 J
- Heat (Q) = ½KE = ½ × 110.25 = 55.125 J
- Mass (M) = 5 g
- Specific heat capacity of lead (C) = 0.129 J/gºC
- Change in temperature (ΔT) =?
Q = MCΔT
Divide both side by MC
ΔT = Q / MC
ΔT = 55.125 / (5 × 0.129)
ΔT = 85.5 °C
Thus, the temperature increase is 85.5 °C

So KE=1/2 0.005 kg * 210m/s^2 = 110 J.
Now the specific heat capacity of lead is 126 J/kgK, so the temperature change= 55 J / 0.005 * 126 J/kgK=87.3015873 K. Which, if normal thermal conditions, the bullet would have a temperature of around 360,451587 Kelvin or, simplified, 107.3 degrees celsius.

What is meant by force of attraction
The force of attraction refers to the physical phenomenon in which objects are drawn toward each other due to gravitational, electromagnetic, or other fundamental forces. This attraction can be explained by several different interactions, including:
Gravitational Attraction: This is the force of attraction between two objects with mass. According to Newton's law of universal gravitation, every mass in the universe attracts every other mass with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
