Components connected in series are connected along a single path, so the same current flows through all of the components. If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is across each bulb and they all glow.
Recall the definitions of
• average velocity:
v[ave] = ∆x/∆t = (x[final] - x[initial])/t
Take the initial position to be the origin, so x[initial] = 0, and we simply write x[final] = s. So
v[ave] = s/t
• average acceleration:
a[ave] = ∆v/∆t = (v[final] - v[initial])/t
Assume acceleration is constant (a[ave] = a). Let v[initial] = u and v[final] = v, so that
a = (v - u)/t
Under constant acceleration, the average velocity is also given by
v[ave] = (v[final] + v[initial])/2 = (v + u)/2
Then
v[ave] = s/t = (v + u)/2 ⇒ s = (v + u) t/2
and
a = (v - u)/t ⇒ v = u + at
so that
s = ((u + at) + u) t/2
s = (2u + at) t/2
s = ut + 1/2 at²
Answer: 53 kPa
Explanation:
Absolute pressure is a pressure value referred to absolute zero or vacuum. This value indicates the total pressure to which a body or system (the chamber in this situation) is subjected, considering the total pressure acting on it.
In this sense, the equation that will be useful in this case is:
(1)
Where:
is the atmospheric pressure
is the vacuum pressure
is the absolute pressure
Isolating
from (1):
(2)
(3)
Finally:
This is the absolute pressure in the chamber
An objects speed is the distance it travles DIVIDED by the amount of time it takes
The child at 5 years old would weight: 60 lb (27.16 kg) If he continues gaining weight a that rate
To solve this problem we will use a rule of three with the problem information:
3 years-------- 36 lb child's weight
5 years -------- x
Applying the rule of three we get:
x = ( 5 years * 36 lb child's weigh) / 3 years
x = 60 lb
By converting the weight units from lb to kg we have:
x = 60 lb * 16.3 kg/36 lb
x = 27.16 kg
<h3>What is rule of three?</h3>
It describes the proportionality of 3 known data and an unknown data. When you have more than 3 known facts that are involved in the proportionality, it is known as a compound rule. The rule of three is also known as a direct proportions.
