Name 3 things food is used for in your body after it is broken down.
Shtirlitz [24]
After break down food may be used in the body to provide energy, as building blocks for tissue and cells, and can be stored for future use.
The body uses food for energy, for growth by making new cells and repairing or replacing tissues, may be stored by converting it into glycogen or fat before they can be stored. The main types of foods are carbohydrates, proteins and fats.

If type AB blood has type A in it, explain why a person with type A blood cannot have a transfusion of type AB blood?
Kaylis [27]

Explanation:

They can't tranfuse because they will have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them

If you have type AB you have both A and B antigens. Therefore you have B too that's why you can't only tranfuse with A after all you have to have to have both types.

a girl pulling a sled with a mass of 6.0 kg to the left with a force of 10.0 N at a 30.0 degree angle. There is a 1.5 N force of
Aleonysh [2.5K]

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:
