It must be a mixture, because the ingredients can be separated. You can precipitate sugar from water, there's no chemical reaction involved. I actually made lemonade pops once and the lemon juice and sugar comes out of solution as the water freezes.

Sati [7]

Answer:

p to the left

Explanation:

According to law of conservation of momentum "total momentum of an isolated system remains constant".

we consider astronaut and astronaut drill as an isolated system. If the drill gain momentum p to the right so in order for momentum to remain constant the astronaut will gain the same momentum but in opposite direction i.e momentum p to the left.

Initial momentum = 0 ( before she throw astronaut belt)

Final momentum = p - p = 0 (After she throw astronaut belt)

Hence momentum of the system remains constant i.e zero.

melamori03 [73]

Answer:

a_r=389\ rev.s^{-2}

n=58350 rev

Explanation:

Given:

time of constant deceleration, t=10\ s

A.

initial angular speed, N_i=3890\ rpm\

<u>Using equation of motion:</u>

N_f=N_i+a_r.t

0=3890+a_r\times 10

a_r=389\ rev.s^{-2}

B.

Using eq. of motion for no. of revolutions, we have:

n=N_i.t+\frac{1}{2} a_r.t^2

n=3890\times 10+0.5\times 389\times 100

n=58350\ rev
