There are a truly enormous number of neutrons in any sample of Element X.

Why, EVERY ATOM of Element X has 38 of them in its nucleus !

The atomic number Z of an element is the number of protons it contains (and in an atom it is equal to the number of electrons). The mass number M is close to the mass of one mol of the substance but it is defined as the number of protons and neutrons in the nucleus of the atom; there, the main mass of the atom is contained. Hence, N=M-Z=74-36=38(since M counts both protons and neutrons while Z only protons). Thus, it has 38 neutrons.

If a car goes along a straight road heading east and speeds up from 45 ft/s to 60. ft/s in 5 sec, calculate the
Lapatulllka [165]

Answer:

Acceleration = 0.9144 m/s^2

Explanation:

Initial speed = 45 ft/s

Final speed = 60 ft/s

Time = 5 sec

Acceleration = a = (v-u) / t

                     = 60-45 / 5

                     = 0.9144 m/s^2

A satellite dish is in the shape of a parabolic surface. Signals coming from a satellite strike the surface of the dish and are
LenKa [72]

Answer: 3.125 ft

Explanation:

If this dish has the form of a concave upward parabola and its vertex p is at the origin, its corresponding equation is:

x^{2}=4py

Where:

x is the radius, which can be found by dividing the diameter d=10 ft by half. Hence x=\frac{d}{2}=\frac{10 ft}{2}=5 ft

y=2 ft is the depth

p is the vertex of the parabola, where its base is

Finding p:

p=\frac{x^{2}}{4y}

p=\frac{(5 ft)^{2}}{4(2 ft)}

Finally:

p=3.125 ft This is where the the receiver should be placed

What are limits that would be age appropriate for teens vs toddlers? give me some examples of limits that you may have for a tee
Pavlova-9 [17]

The limits which would be age appropriate for toddlers include being flexible and realistic while that of a teen should be more rigid.

<h3>Who are Toddlers?</h3>

This refers to a child whose age ranges from 1 year to 4 years and limits set for them should be flexible due to it helping them feel more secure and decreases anxiety.

Example of limits that you may have for a teen is reducing their screen time while an example of limits for toddlers is correcting their junk eating habits. Teens should have a rigid limit so as to enable them do the right things at all times due to their strong emotions.
