Answer:
Explanation:
mechanical advantage = output force / input force
= 740 N / 55 N
= 13.45
Answer: 12.44 millisecond
Explanation:
Based on the information given, to know the time taken for the impulse, which travels a distance of 1.58m to reach the brain will be:
Time taken = Distance/Speed
Time taken = 1.58/127
Time taken = 0.01244
Time taken = 12.44 millisecond.
Answer: Second choice (straight down arrow)
Explanation:
I just did it.
Answer:
Publishing results of research projects in peer-reviewed journals enables the scientific and medical community to evaluate the findings themselves. It also provides instructions so that other researchers can repeat the experiment or build on it to verify and confirm the results.
Answer:
4. Downward and its value is constant
Explanation:
As this is a case of projectile motion, we use the reference frame where upward direction to be positive for 
, and in the same way to be negative in the downward direction. On another hand, we have that gravity is always acting this means that gravitational acceleration g is directed downward constantly over the dart not only during the upward but also during the downward part of the trajectory. And it is ruled by the following equations.
For the x-axis
For the y-axis
Where 
, is the initial velocity.
