When a projectile reaches the highest point the vertical component of the acceleration is:

Physics
1 answer:
Mazyrski [523]3 years ago
6 0

Answer:

The acceleration is g.

Taking the upward direction as positive

V = Vy y - 1/2 g t^2

Taking the downward direction as positive

V = -V y + 1/2 g t^2

One can choose either direction as positive, but the acceleration is

the same as g (it is g) while the projectile is in the air.

Binding of a signaling molecule to ligand-gated ion channel leads directly to a change in the distribution of ions on opposite sides of the membrane

<u>Explanation:</u>

The ligand-gated-ion-channel is trans membrane protein buildings that conduction course through the channel pores in light of the official of a neurotransmitter. They are not quite the same as voltage - gated - ion - channels, which are delicate to film possibilities, and G-protein coupled receptors (GPCR's), which utilize second messengers.

These ion channels, additionally ordinarily referred to as ionotropic receptors, are a gathering of trans membrane -ion-channel proteins which open to permit ions, for example, N a^{+}, K^{+} and potentially c l^{-} to go through the layer in light of the official of a synthetic errand person, for example, a neurotransmitter.

A beam of monochromatic light is aimed at a slit of width and forms a diffraction pattern. In which case is the width of the cen
AysviL [449]

When the incident light is yellow the width of the central band greater. Single-wavelength light sources are known as monochromatic lights, where mono stands for one and chroma for color. Monochromatic lights are defined as visible light that falls inside a specific range of wavelengths. It has a wavelength that falls within a constrained wavelength range.

A laser beam is the ideal illustration of monochromatic light. A monochromatic light beam produced by a single atomic transition with a particular single wavelength is what makes up a laser. A color scheme that consists solely of different shades of one color is referred to as monochromatic.
