what is the force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second
vichka [17]

Answer:

The force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second is 12 newton.

Explanation:

  • According to Newton's second law based motion "the moving object's acceleration is based upon two terms - one is the total force acting upon that object and the other one is the net mass of the object."
  • In mathematical term, F=ma. where F= force, m= mass, a= acceleration.
  • So, by performing the calculation, \bold{\mathrm{F}=30 \times 0.4 \mathrm{N}=12 \mathrm{N}}
  • 12N force will move the boy along with the wheel chair.

What occurred during immune system development to result in the presence of antibodies that can bind to the thyroid receptor? g
almond37 [142]

Answer:

If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.

Explanation:

This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.

The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.
