For the girl pulling a sled with a mass of 6.0 kg t the left with a force of 10.0 N at a 30.0° angle, we have:

a) The normal force acting on the sled is 294 N.

b) The acceleration of the sled is 1.2 m/s².

a) We can calculate the normal force acting on the sled, with the sum of all the forces acting in the vertical direction:

(1)

Where:

W: is the weight force or force of gravity = 58.8 N

: is the component of the applied force in the y-direction

N: is the normal force =?

The vertical component of the force () can be calculated as follows:

(2)

Where:

F: is the applied force = 10.0 N

θ: is the angle (with the horizontal) = 30.0°

By entering equation (2) into (1) we have:

Hence, the normal force acting on the sled is 294 N.

b) The acceleration of the sled can be found with the forces acting on the x-direction:

Where:

a: is the acceleration =?

m: is the mass = 6.0 kg

: is the component of the applied force in the x-direction = Fcos(θ)

: is the force of friction = 1.5 N (it is negative because is in the opposite direction of motion)

Therefore, the acceleration is:

Describe the main molecule found in nucleus and explain how it controls the cells functioning​
SCORPION-xisa [38]

The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

Non example of mitochondrion
Yuliya22 [10]
The number of mitochondria per cell varies widely; for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.
