Assume that the turntable deccelerated during time Δt before reaching the final angular velocity ( Δt is the time interval betwe
Zina [86]

Answer:

See below...

Explanation:

Let’s express ⟨α⟩ in terms of ωi , ωf , and Δt. and torque in terms of It , ωi , ωf , and Δt.

STEP 1.  

The rate of change of angular velocity is Angular acceleration.  

The net change in angular velocity is Average angular acceleration divided by the elapsed time.

⟨α⟩ = ω f −ω i/Δt

STEP 2.

Torque is assumed this way

          dω

   τ = I ----

           dt

.

⟨τ ⟩ = I t (ω f −ω i )/Δt

The reactants for a certain chemical reaction are shown. Cu(NO3)2 + NaOH → Which of the following shows the correct product or p
valentinak56 [21]

Answer : The products of this reaction are, Cu(OH)_2 and NaNO_3

Explanation :

First we have to write the balanced chemical reaction.

Cu(NO_3)_2+2NaOH\rightarrow Cu(OH)_2+2NaNO_3

In this reaction, 1 mole of copper nitrate react with the 2 moles of sodium hydroxide to give 1 mole of copper hydroxide and 2 moles of sodium nitrate.

This reaction is a double displacement reaction.

Double displacement reaction : A type of reaction in which a positive cation and a negative anion of two reactants react to exchange their places to form two new products.

The general representation of this reaction is,

XY+AB\rightarrow XB+AY

(X and A are the cations, Y and B are the anions)

Hence, the products of this reaction are, copper hydroxide,Cu(OH)_2 and sodium nitrate,NaNO_3

How is the bike in the picture a system and how is the Earth a system?
JulijaS [17]

Answer:

The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.
