To simplify a fraction, we have to divide the numerator and the denominator by the same number. In this case, both aspects of the fraction are divisible by 9.
When we divide the numerator by 9 we get 3
When we divide the denominator by 9 we get 7
So, the simplest form of 27/63 is 3/7
The time interval in which the larger force act is 1.1 seconds.
<h3>What is impulse?</h3>
The impulse produced by an object is determined from the product of force and time of force of the object.
The impulse experienced by an object is the product of mass and velocity of the object or simply the impulse experienced by object is equal to change in the momentum of an object.
J = Ft
where;
- F is the applied force
- t is the time of force acting
The magnitude of the force that produce impulse of 3 Ns for 3.2 seconds is calculated as;
F = J/t
F = (3 Ns) / (3.2 s)
F = 0.94 N
The magnitude of the force that is three times larger is calculated as;
F₂ = 3 x 0.94 N
F₂ = 2.82 N
The time interval of the larger force is calculated as;
t₂ = J/F₂
t₂ = 3 / 2.82
t₂ = 1.1 seconds
Thus, the impulse experienced by an object is a function of force and time of force action.

Answer:
I would say A.
Explanation:
Homeostasis is pretty much a state of rest or equilibrium. Only A counts, as that wolf is trying to catch its breath and lower its breathing rate and heart rate.
(I could be wrong if B counts. Ya know, if the spider needs to stop being hungry?)
Let's think of an example, water boiling to form steam.
When the water boils, it obviously does not have the same shape, and liquids and gases don't have a definite shape, so shape is not the answer.
To force a phase change, water needs energy in the form of heat, so temperature is also not the answer.
The volume is also changed, and gases take up more space than liquids, so volume is also not the answer.
So, after ruling the other three out, the one we're left with is mass, and that is the answer: mass remains constant during a phase change
