Answer:

Mg will replace Ag in a compound

Explanation:

A single replacement reaction is driven by the position of ions on the activity series.

As a rule of thumb, the position of metal ions on the activity series determines their reactivity.

Metal ions that are above another are more reactive and they will displace those that are lower.

Generally, activity increases as we go up the group.

Mg ions are higher than Ag ions on the series so, Mg will displace Ag from a solution.

A child is riding a merry-go-round, which has an instantaneous angular speed of 1.25 rad/s and an angular acceleration of 0.745
Elena L [17]

w = instantaneous angular speed = 1.25 rad/s

r = radius = 4.65 m

α = angular acceleration = 0.745 rad/s²

centripetal acceleration is given as

a_{c} = rw²

a_{c} = (4.65 ) (1.25)² = 7.27 m/s²

tangential acceleration is given as

a_{t} = rα

a_{t} =4.65 x 0.745 = 3.46 m/s²

angle is given as

\theta = tan^{-1}(\frac{a_{c}}{a_{t}})

\theta = tan^{-1}(\frac{7.27}{3.46})

\theta = 64.5 deg

What is Snell's Law?​
polet [3.4K]

Answer:

law stating that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.

Snell's law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. ... Snell's law asserts that n1/n2 = sin α2/sin α1.

Can the magnitude of a vector have a negative value? Explain.
stiks02 [169]
The magnitude of a vector is the square root of its components squared. When you square a negative number, you will always get a positive number. Its like speed of your car. It will always be positive (or 0) whether you are moving forward or you are in reverse gear or stationary.
