Answer:
The minimum pulling force required to start it moving is

equal to the static frictional force.

F = (mass) x (gravity) x (coefficient of static friction).

Once it's moving, the force required to keep it moving at a steady speed,

without speeding up or slowing down, is the force of kinetic friction.

F = (mass) x (gravity) x (coefficient of kinetic friction).

In both equations, [ (mass) x (gravity)] is just the object's 'weight'.

**Answer:**

** fibroblast cells**

**Explanation:**

Periosteum is thin connective tissue layer covering the bone. It contains fibroblast cells outside and progenitor cells inside. **So, the cells most involved in the repair is fibroblast cells. It is typical type of biological cell that synthesizes matrix and collagen, produces the stroma for animal tissues and plays vital role in healing wounds**

Shock waves can be observed in outer space between planets where there is very little matter. Although little, plasma does exist in outer space which allows the waves to travel.

**Answer:**

Either A or C

**Explanation:**

there are 2 quizlets with 2 different answers, i don't know, man.

**Answer:**

**Explanation:**

Given

Dolphin leaps out an angle

Horizontal component of dolphin velocity

Suppose u is the launch velocity of dolphin

therefore

and vertical velocity

divide 1 and 2 we get

b. only within the moon’s umbra.

c. only within the moon’s penumbra.

d. only the dark side of Earth.

**Answer:**

b. only within the moon’s umbra.

**Explanation:**

Solar eclipse occurs when Moon comes between the Sun and the Earth in straight line and blocks the sunlight. A shadow of moon castes on the surface of the Earth. **The region passing through the moon's umbra would view a total solar eclipse. **The moon completely hides the surface of the sun. It would be visible to the people residing in the bright side of the Earth within the Umbra of the moon.

Only within the umbra of the moon's shadow.

When the book is placed in the middle, the forces acting on p and q is 5N. When the book is moved 50 cm from q, the forces at p and q can be solved by doing a moment balance

With p as the pivot

Fq (2 m) = 10 N (0.5 m)

Fq = 2.5 N

and

Fp = 10 N - 2.5 N = 7.5 N

With p as the pivot

Fq (2 m) = 10 N (0.5 m)

Fq = 2.5 N

and

Fp = 10 N - 2.5 N = 7.5 N

**Answer:**

Fq = 2.5N

Fp = 7.5N

**Explanation:**

Hello! Let's solve this!

When the book is in the middle, the force in p (Fp) and the force in q (Fq) are equal, and half of the total force

Fp = Fq = 5N

When the book moves 0.5m from q we have a balance

Fq * 2m = 10N * 0.5m

We cleared Fq

Fq = (10N * 0.5m) / 2m

Fq = 2.5N

Fp = 10N-Fq = 10N-2.5N = 7.5N

Conclusion

**Fq = 2.5N **

**Fp = 7.5N**
