b-testing
Explanation:
First would be observation/research. Then the hypothesis. After that you would test your theory, conduct experiments. And finally, your conclusion- what you got from the whole process basically.
Hope this helps.
Answer:
a) 
= 4.67m/s
b) V = 8.29 m/s
Explanation:
Givens:
The bullet is 5.30g moving at 963m/s and its speed reduced to 426m/s. The wooden block is 610g.
a) From conservation of linear momentum
Pi = Pf
where 
are the mass and the initial velocity of the bullet, 
and 
are the mass and the initial velocity of the wooden block, and and 
are the final velocities of the wooden block and the bullet
The wooden block is initial at rest 
this yields
By solving for adn substitute the givens
= 
= 
= 4.67m/s
b) The center of mass speed is defined as
substituting:
V = 8.29 m/s
So we can know what is in space maybe weird or interesting stuff
Answer:
Negative 3
Explanation:
Bc scientific notation is the zeros either ahead or behind the actual numbers
The best tree stand safety harness is the Hunter Safety System Hybrid Flex Safety Harness, with its awesome ElimiShield Scent Control Technology.
Moreover, These stands are designed to be attached directly to the tree. Hunters using a fixed or suspended stand must choose a method of climbing up and down from the platform. The safest and most used method is sectional ladders.
