Answer:
C
Explanation:
The sun has rotated causing the shadow to reflect.
Answer: 846°C
Explanation:
The quantity of Heat Energy (Q) required to heat bismuth depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Given that:
Q = 423 joules
Mass of bismuth = 4.06g
C = 0.123 J/(g°C)
Φ = ?
Then, Q = MCΦ
423 J = 4.06g x 0.123 J/(g°C) x Φ
423 J = 0.5J/°C x Φ
Φ = (423J/ 0.5g°C)
Φ = 846°C
Thus, the change in temperature of the sample is 846°C
We can find the average speed of the body by finding the total distance covered, and then dividing it by the total time of the motion.
The total distance covered is:
![S=30 m + 45m+65m=140 m](https://tex.z-dn.net/?f=S%3D30%20m%20%2B%2045m%2B65m%3D140%20m)
while the total time of the motion is
![t=5 s+7s+5 s=17 s](https://tex.z-dn.net/?f=t%3D5%20s%2B7s%2B5%20s%3D17%20s)
So, the average speed of the body is:
You are in an early universe.
In the study of the evolution of the universe, it has been determined before Plank time (before the big bang and right after it), the early universe had the following characteristics:
- There was only one single force acting over all that existed.
- The early universe was very hot and dense because all matter had contracted before the big bang.
- Space and time were wrapped.
These characteristics match the ones described, based on this, we can conclude you are in an early universe.
