Well, you get the movement as the arc in radians times the radius, which we need to find. Doing \frac{3.15}{1.82}=1.73, which is about \sqrt{3} meters.

What causes the particles within the nucleus of an atom to bond together? Question 12 options: electromagnetism gravity weak nuc
monitta

Answer:

Strong nuclear force

Explanation:

The particles in the atom's nucleus bond together because there is a strong nuclear force between the protons and neutrons that attracts them to each other and binds together the nucleus.

Radio waves are readily diffracted around buildings, whereas light waves are negligibly diffracted around buildings. This is bec
Tom [10]

Answer:

Radio waves have longer wavelength

Explanation:

Radio wave is an electromagnetic frequency that has the ability to travel through long distance. They have frequencies shuttling been the range of 10^4 hz and a frequency of 10^12 hz

Light wave is also called visible light. This is because it is visible to the naked eye, despite it being in the electromagnetic spectrum. It's frequency is usually between 4*10^-7 hz and a frequency of 7*10^-7 hz.

As can be seen from both, the radio waves length are quite far stronger than that of the light waves.

The definition of speed is (distance covered) / (time to cover the distance) .

So a unit of speed has to be (a unit of length) / (a unit of time) .

Here are several perfectly fine units of speed:

-- miles per hour

-- feet per second

-- meters per second

-- kilometers per hour

-- inches per second

-- centimeters per minute

-- yards per Century

-- furlongs per fortnight

-- nanometers per microsecond

-- Smoots per week

-- parsecs per millenium

The noble gas neon is used for filling neon signs. Like other noble elements, it has a full octet (complete outer energy level)
DanielleElmas [232]

Answer:

C. unlikely to combine with other elements.

Explanation:

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

Noble gases are chemical elements with eight valence electrons and as such have a full octet. Some examples are argon, neon, etc.

Hence, the full octet makes the gas (neon) unlikely to combine with other elements.

A 10.0 g bullet moving at 300m/s is fired into a 1.00 kg block at rest. The bullet emerges (the bullet does not get embedded in
chubhunter [2.5K]

Answer:

v' = 1.5 m/s

Explanation:

given,

mass of the bullet, m = 10 g

initial speed of the bullet, v = 300 m/s

final speed of the bullet after collision, v' = 300/2 = 150 m/s

Mass of the block, M = 1 Kg

initial speed of the block, u = 0 m/s

velocity of the block after collision, u' = ?

using conservation of momentum

 m v + Mu = m v' + M u'

 0.01 x 300 + 0 = 0.01 x 150 + 1 x v'

v' = 0.01 x 150

v' = 1.5 m/s

Speed of the block after collision is equal to v' = 1.5 m/s
