Sorrrryyyy just need some points
Well, relative dating is the science determining the relative order of past events like the age of an object compared to another object without determining the absolute age. The absolute age is the process of determining an age on a specific chronology in archeology and geology. Some scientists prefer the terms chromatic or calendar dating, as the word absolute implies an unwarranted certainty or accuracy. Hope I helped
Answer:
180 miles/hr
Explanation:
15 min=1/4 hr
s= distance/time
s=45miles/1/4 hr
s=45miles x 4/1=180 miles/hr
Answer:
distance = 6 m
Explanation:
- Distance is a scalar quantity (so, only magnitude, no direction), and it is calculated as the scalar sum of all the distances travelled by an object during its motion, regardless of the direction. So, in this problem, the distance covered by the pinecone is
d = 4 m + 2 m = 6 m
- Displacement is a vector quantity (magnitude+direction), and its magnitude is calculate as the distance in a straight line between the final position and the initial position of the object. In this case, the final position is 2 m west and the initial position is 0 m, so the displacement of the pinecone is
d = 2 m west - 0 m = 2 m west
So, a scalar quantity from this scenario is
distance = 6 m
Answer:
Explanation:
The sum of the kinetic and electric potential energies of the proton when initially released must be equal to their sum at infinity, so we have:
Which, since 
because initially the proton is at rest, is:
where 
is Coulomb's constant, 
the charge of the proton, 
the charge of the gold nucleus, since it has 79 protons, 
the initial separation between them, 
the mass of the proton and v its final velocity. 
is very far away, so the final electric potential will be 0J, and we have:
