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
Answer:
The acceleration at the astronaut's head decreases.
Explanation:
Since the centripetal acceleration equals acceleration due to gravity,
a = g = GM/R². since a changes infinitesimally from his foot to his head, we differentiate a with respect to r to get da/dr = -2GM/R³.
So, da, the change in acceleration = -2GMdR/R³ = -2gdR/R = -2 × 9.8/6.4 × 10⁶ m = -3.0625 × 10⁻⁶dR m/s².
Since dR = height of astronaut = 1.80 m, da = -3.0625 × 10⁻⁶ × 1.8 = -5.5125 × 10⁻⁶ m/s².
So the acceleration at the astronaut's head is g + da = 9.8 - 0.0000055125 = 9.7999944875 m/s².
So the acceleration at the astronaut's head decreases.
One of the main arguments that animal rights advocate present is that animals have rights because they<u> are capable of suffering</u>.
<h3>What are animal rights?</h3>
Animal rights are ethical visions founded on the trust that animals deserve the space to live their own lives without being affected by mortal interests.
Humans have to always give freedom to animals for their living without their personal interests.
The animal is capable to suffer this is an argument that comes always on the animal rights sheet.
Hence the option B is correct.

Part 1. F= m*a
M=12kg
A= 3 m/s^2
So F = 12kg * 3 m/s^2 which means
F=36 Newton’s
Part 2. F=12000N
M= F/A
A=4 m/s^2
So M= 12000N / 4 m/s^2
Which means M=3000 kg
<span>Well, I just took this unit. There are two main kinds of cells, which are made up of smaller organelles: Nucleus, Vacuoles etc. The two main types are Plant and animal. Only Plant cells have walls.</span><span />
