Answer:
Therefore the rate of corrosion 37.4 mpy and 0.952 mm/yr.
Explanation:
The corrosion rate is the rate of material remove.The formula for calculating CPR or corrosion penetration rate is
K= constant depends on the system of units used.
W= weight =485 g
D= density =7.9 g/cm³
A = exposed specimen area =100 in² =6.452 cm²
K=534 to give CPR in mpy
K=87.6 to give CPR in mm/yr
mpy
=37.4mpy
mm/yr
=0.952 mm/yr
Therefore the rate of corrosion 37.4 mpy and 0.952 mm/yr.
Answer:
= 3.87 m/s
Explanation:
Since momentum is conserved, momentum right before and after the boy jumps onto the skateboard should be the same.
Initial momentum = momentum of boy = 43.2 x 4.10 = 177 kg·m/s
Final momentum = momentum of boy and skateboard = (43.2 + 2.50) x v = 45.7v
177 = 45.7v
v = 177 / 45.7 = 3.87 m/s
(Hope this helps can I pls have brainlist (crown)☺️)
The strongest of the natural forces is Strong Nuclear, followed by Electromagnetic, then Weak Nuclear and lastly Gravitational.
So from weakest to strongest: gravitational --> weak nuclear --> electromagnetic --> strong nuclear
Answer C)
Answer:
7.95 meters
Explanation:
The magnitude of a vector can be found with Pythagorean's theorem:
v² = vx² + vy²
v² = (-7.55)² + (-2.48)²
v² = 57.0 + 6.15
v² = 63.15
v = 7.95
The magnitude of the vector is 7.95 meters.
