The mechanical advantage is the factor by which
the machine multiplies the input force.
If the MA is 3 and the input force is 630N, then
the output force is
(3) x (630N) = 1,890N
Answer:
Explanation:
for the unit vector, we need to divide the given vector by its norm, because it should be in the SAME direction as the original vector, but of magnitude "1".
We notice that the norm of the given vector is:
Then, the unit vector becomes:
Answer: A, B, and D,
C is incorrect because continental drift takes several centuries to move the tectonic plates witch is not an immediate impact leaving you with A,B, and D.
Answer:
Acceleration of the bullet while moving into the clay is -312500 ms⁻²
Explanation:
Given data
Initial velocity (v₁) = 250 m/s Final velocity (v₂) = 0 m/s
Distance (s)= 0.1 m acceleration (a) = ?
Using 3rd equation of motion
2as = v₂²- v₁²
2 × a × 0.1 = 0² - 250²
0.2 × a = -62500
a = -62500/0.2
a = -312500 m/s²
Here negative sign indicate that bullet slow down and it is deceleration i.e negative acceleration.
