If the child is gaining weight at an expected rate, a child who weighs 36 lb (16.3 kg) at 3 years of age would weigh what amount

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.

Which sequence correctly reflects the order in which electrical charges occur during an action potential, from first to last?
Lady_Fox [76]
This sequence refer to how neurons send messages electrochemically. When the neurons are at rest, they are at its resting potential at -70 millivolts. If the neurons in the brain send messages, a spike would occur until it reaches the threshold potential at -55 mV. If it reaches the threshold potential, then an action potential occurs.Hence, the sequence would be letter C.

An amusement park ride called the Rotor debuted in 1955 in Germany. Passengers stand in the cylindrical drum of the Rotor as it
steposvetlana [31]

Answer:

μs = 0.36

Explanation:

  • While the drum is rotating, the riders, in order to keep in a circular movement, are accelerated towards the center of the drum.
  • This acceleration is produced by the centripetal force.
  • Now, this force is not a different type of force, is the net force acting on the riders in this direction.
  • Since the riders have their backs against the wall, and the normal force between the riders and the wall is perpendicular to the wall and aiming out of it, it is easily seen that this normal force is the same centripetal force.
  • In the vertical direction, we have two forces acting on the riders: the force of gravity (which we call weight) downward, and the friction force, that will oppose to the relative movement between the riders and the wall, going upward.
  • When this force be equal to the weight, it will have the maximum possible value, which can be written as follows:

       F_{frmax} = \mu_{s}* F_{n}  = m * g  (1)

  • where μs= coefficient of static friction (our unknown)
  • As  we have already said Fn = Fc.
  • The value of the centripetal force, is related with the angular velocity ω and the radius of the drum r, as follows:

      F_{n} = m* \omega^{2} * r  (2)

  • Replacing (2) in (1), simplifying and rearranging terms, we can solve for μs, as follows:

       \mu_{s} = \frac{g}{\omega^{2} r}  (3)

  • Prior to replace ω for its value, is convenient to convert it from rev/min to rad/sec, as follows:

       \omega = 26.0 \frac{rev}{min} * \frac{1min}{60 sec} *\frac{2*\pi rad }{1 rev} = 2.72 rad/sec (4)

  • Replacing g, ω and r in (3):
  • \mu_{s} = \frac{g}{\omega^{2} r} = \frac{9.8m/s2}{(2.72rad/sec)^{2} *3.7 m} = 0.36 (5)

Form of communication that reaches large audiences without personal contact.
lukranit [14]
Socialization is the process of internalization of the norms and ideologies of society by an individual. It encompasses learning and teaching to attain social and cultural continuity. It also has various forms. One of which is the MASS MEDIUM/MEDIA which is a form of communication that does not need personal contact to relay or convey and information. Examples of which are books, films, internet, magazines and so forth.
