Answer:

c. Joints allow the roadway to expand and contract as cars put force on the bridge

Explanation:

Joints in the roadways of bridges allows for the roadway to expand and contract as cars put force on the bridge.

The force on the bridge and the ambient temperature causes expansion of the materials used in making the bridge.

  • Joints allows and accommodate the expansion.
  • As the force is removed and temperature reduces, the road also contracts.

denis-greek [22]

Answer:

he electron is directly transferred to NADP+ to NADPH, but electron flow is used to generate a proton gradient for ATP synthesis. Electron is not directly transferred to ATP

Kelli weighs 425 N, and she is sitting on a playground swing that hangs 0.36 m above the ground. Her mom pulls the swing back an
kodGreya [7K]

Answer:

V = 3.54 m/s

Explanation:

Using the conservation of energy:

E_i = E_f

so:

wh = \frac{1}{2}mV^2

where w is te weigh of kelly, h the distance that kelly decends, m is the mass of kelly and V the velocity in the lowest position.

So, the mass of kelly is:

m = 425N/9.8 = 43.36 Kg

and h is:

h = 1m-0.36m =0.64m

then, replacing values, we get:

(425N)(0.64m) = \frac{1}{2}(43.36kg)v^2

Solving for v:

V = 3.54 m/s
