<span>Bones. The most important organ of the skeletal system is the bones.

Ligaments and Joints. Another important component, i.e. the ligaments are made of fibrous collagen tissue that attaches one bone to another bone.

A block of mass 12.2 kg is sliding at an initial velocity of 6.65 m/s in the positive x-direction. The surface has a coefficient

valentina_108 [34]

Explanation:

Given that,

Mass of the block, m = 12.2 kg

Initial velocity of the block, u = 6.65 m/s

The coefficient of kinetic friction, $\mu_k=0.253$

(a)The force of kinetic friction is given by :

$f=\mu_k mg$

mg is the normal force

So,

$f=0.253\times 12.2\times 9.8\\\\f=30.24\ N$

(b) Net force acting on the block in the horizontal direction,

f = ma

a is the acceleration of the block

$a=\dfrac{f}{m}\\\\a=\dfrac{30.24}{12.2}\\\\a=2.47\ m/s^2$

(c) Let d is the distance covered by the block before coming to the rest. Using third equation of motion as follows :

$v^2-u^2=2ad\\\\d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{-(6.65)^2}{2\times 2.47}\\\\d=-8.95\ m$

Hence, this is the required solution.

You could do something about Einstein's theory of energy... it seems like it would be a simple and easy project. E=mc^2

Four different resistors have various amounts of electric current flowing through them.

salantis [7]

Answer:

Order will be Forth resistor , first resistor, second resistor, third resistor

Explanation:

We have given four different resistance and current flowing through them

In first resistor resistance R = 4 ohm and current flowing i = 6 A

According to ohm's law voltage = current × resistance = 6×4 = 24 volt

In second resistor resistance R = 2 ohm and current i = 9 A

So voltage V = 9×2 = 18 volt

In third resistor resistance R = 2 ohm and current i = 3 A

So voltage V = 3×2 = 6 volt

In forth resistor resistance R = 8 ohm and current i = 8 A

So voltage V = 8×8 = 64 volt

So order of highest voltage to lowest voltage is 64,24,18,6

Forth resistor , first resistor, second resistor, third resistor
