How do hormones affect only certain cells in the body but not others?

1 answer:

4 0

I<span>f you have studied enzymes its a similar concept. Cells have proteins on the surface of their cell which hormones bind to (called receptors) The receptor must be a complimentary shape to the hormone for it to bind. Only target cells have the receptor with the complimentary shape so only these cells will be affected.</span>

You take the same 3 kg metal block and slide it along the floor, where the coefficient of friction is only 0.4. You release the

spin [16.1K]

Answer:

1.52905 seconds

4.58715 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

$\mu$ = Coefficient of friction = 0.4

g = Acceleration due to gravity = 9.81 m/s²

a = Acceleration = $\mu g$

Equation of motion

$v=u+at\\\Rightarrow t=\frac{v-u}{\mu g}\\\Rightarrow t=\frac{0-6}{-0.4\times 9.81}\\\Rightarrow t=1.52905\ s$

It will take 1.52905 seconds for the block to slow down

$v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2\mu g}\\\Rightarrow s=\frac{0^2-6^2}{2\times 0.4\times -9.81}\\\Rightarrow s=4.58715\ m$

The block will travel 4.58715 m before it stops

Question 26 (1 Point)

LUCKY_DIMON [66]

The book continue to move due to its inertia

Explanation:

We can answer this question by using Newton's first law, which states that:

"When an object is moving with constant velocity (or it is at rest), it will continue moving with constant velocity (or will stay at rest) unless acted upon an external unbalanced force".

This law is also known as law of inertia.

If we apply this law to the situation in the problem, we notice that:

- Before the car stops, the book is moving with constant velocity (25 mph) together with the car

- When the car stops, there are no external forces acting on the book, which is free to continue its motion: so, the book will continue moving at 25 mph forward, due to its inertia. The book will be eventually stopped when it hits the floor (because the floor applies an unbalanced force on it).
