Answer:
A. the pancake that forms is a different state of matter.
Explanation:
because the pancake mix is liquid ,and when you cook it you for a solid.
Salt water is not an example of suspension as salt dissolves in water and combines with it rather than float in the water.
Answer:
the hotter it gets, the liquid(mercury), expands more and more, and will rise up the tube to the correct line to read the tempature
Answer:
18.63 N
Explanation:
Assuming that the sum of torques are equal
Στ = Iα
First wheel
Στ = 5 * 0.51 = 3 * (0.51)² * α
On making α subject of formula, we have
α = 2.55 / 0.7803
α = 3.27
If we make the α of each one equal to each other so that
5 / (3 * 0.51) = F2 / (3 * 1.9)
solve for F2 by making F2 the subject of the formula, we have
F2 = (3 * 1.9 * 5) / (3 * 0.51)
F2 = 28.5 / 1.53
F2 = 18.63 N
Therefore, the force F2 has to 18.63 N in order to impart the same angular acceleration to each wheel.
