Answer:
Answer:
77.58°
Explanation:
Let the projectile is projected at an angle θ and the velocity of projection is u.
At the maximum height, the projectile has only horizontal component of velocity.
Let the velocity at maximum height is v.
According to the question, the velocity at maximum height is 21.5% of initial velocity.
v = 21.5 % of u
u Cos θ = 21.5 % of u
u Cos θ = 0.215 u
Cos θ = 0.215
θ = 77.58°
Thus, the angle of projection is 77.58°.
Explanation:
It's 0 m/s because you're both moving on the same machine at the same speed, so it appears that they're not moving

Answer:
Bind it to a large protein
Explanation:
An antigen is a molecule that binds to Ag-specific receptors, but cannot necessarily induce an immune response in the body by itself. Antigens are proteins , peptides (amino acid chains) and
polysaccharides (chains of monosaccharides/simple sugars) but
lipids and nucleic acids become antigens only when combined with proteins and polysaccharides. [4] In general, saccharides and lipids (as opposed to peptides) qualify as antigens but not as immunogens since they cannot elicit an immune response on their own. Furthermore, for a peptide to induce an immune response it must be a large enough size, thus binding to proteins
