**Answer: After acceleration the iron nuclei travel at a steady speed of one-tenth of the speed of light .the speed of light is 3.00 x 10^8. calculate ...**

**Explanation:**

**Answer:**

**Explanation:**

The main reason spiders spin webs is to catch their dinner. When an insect, such as a fly, flies into a spider's web, it gets stuck on the sticky threads. When a spider catches prey in the sticky strands of its web, it approaches the trapped insect and uses its fangs to inject venom.

**Answer:**

**Explanation:**

A)

W = work done by the freezer = 800 J

Q = heat removed from the freezer = 1735 J

Q' = Heat expelled into the room

Coefficient of performance is given as

inserting the values

B)

Heat expelled is given as

Q' = W + Q

Q' = 800 + 1735

Q' = 2535 J

**Answer:**

7,272.7m

**Explanation:**

Our knowns:

a = 5.2m/s^2

t = 32.8s

= 0 m/s

Our Unknowns:

Distance (x): ?

We can use displacement formula:

ΔX = t + a

Plug in knowns:

X = 0 + 1/2 ((5.2)(32.8))^2

Answer:

ΔX = 7272.7m

(I beleive this should be right) let me know if it helped!

**Answer:**

8.89 m/s² west

**Explanation:**

Assume east is +x. Given:

v₀ = 120 m/s

v = 0 m/s

t = 13.5 s

Find: a

v = at + v₀

0 m/s = a (13.5 s) + 120 m/s

a = -8.89 m/s²

a = 8.89 m/s² west
