Answer:
The average angular acceleration is -2.628 rad/s²
Explanation:
Counterclockwise = positive
Clockwise = -negative
Given;
initial rotation of the flywheel, θ₁ = 6.55 rotation/s
final rotation of the flywheel, θ₂ = - 2.19 rotation/s
The average angular acceleration is given by;
Therefore, the average angular acceleration is -2.628 rad/s²
Christian made 1000 pancakes.
Explanation:
Let us represent the total amount of Pancake made by Christian as = K
From the problem;
Christian ate of the pancake in the morning =
* K =
K
We know that Christian cannot eat her pancake and at the same time have it, the remaining pancake will then be:
total amount of cake - fraction eaten
Remainder = K - K=
K
In the afternoon, we know that she ate 1/4 of the remaining cake:
K*
K =
K
The remaining cake in the afternoon will be:
Total amount of cake remaining from morning - amount eaten in the afternoon
= K -
K
= K
The fraction of the cake remaining in the afternoon is K
Since she had 300cakes left in the afternoon, then :
K= 300
K = 1000 pancakes
Therefore Christian made 1000 pancakes.

Answer:
Explanation:
Given
Pressure, Temperature, Volume of gases is
Let P & T be the final Pressure and Temperature
as it is rigid adiabatic container therefore Q=0 as heat loss by one gas is equal to heat gain by another gas
where Q=heat loss or gain (- heat loss,+heat gain)
W=work done by gas
change in internal Energy of gas
Thus from 1 & 2 we can say that
where
and
Explanation:
A double replacement reaction is a reaction in which two different compounds are mixed together and both their cations and anions get exchanged with each other respectively.
When potassium bromide reacts with silver nitrate then it results in the formation of potassium nitrate and silver bromide.
The chemical reaction equation is as follows.
