the complete question in the attached figure
we have that
d=0.51 mm------------------------- >0.00051 m
v = √(2ad) = √(2 * 1300m/s² * 0.00051 m) = 1.15 m/s initial velocity
a=9.8 m/s²
Then d = v² / 2a = (1.15m/s)² / (2*9.8) m/s² = 0.059 m = 59 mm
the answer is 59 mm
Answer:
b. 48.0 g.
Explanation:
Given;
mass of the exoplanet,
radius of the exoplanet,
The acceleration due to gravity of the planet is calculated as;
Therefore, the correct option is b. 48.0 g
Answer:

Explanation:
You have to subtract them to find your answer and 178 - 176= 2
True, scientists often talk to each other to figure out if their results were similar and what they could have done better.
Although, talking to other scientists does have risks, other scientists could copy your work and further better it.
So, your final answer is TRUE, sorry for the long answer, I needed to have a word count about 20 characters and then I got carried away! lol
