<span>Fasteners are double or triple threaded with the idea of durability. People look for durability in a fastener and if they receive one with triple threaded or double threaded they will feel more safe and at ease knowing it has extra strength added.</span>
Because it demonstrates the relationship between a body and the forces acting upon it, and its motion in response to those forces. [Hope that helps]
Potential energy = mass x gravity x height
P.E = 4 x 9.8 x 3
P.E = 117.6 J
i’m not 100 percent sure but I need points to ask questions good luck th
A car with a velocity of 22 m/s is accelerated at a rate of 1.6
for 6.8s has the final velocity t be 32.88 m/s.
The acceleration means the amount of velocity changing per unit time.
The given data:
initial velocity, u = 22 m/s
time, t = 6.8 s
acceleration, a = 1.6 
We will be using the equation of motion:
v = u + at



The final velocity become 32.88 m/s.
