How can you increase the momentum of an object?

(a) by decreasing its velocity
(b) by increasing its friction
(c) by increasing its mass
(d) by decreasing its acceleration

Answers

Answer:

(c) by increasing it's mass

Answer:

(C) by increasing its mass

Explanation: Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

What constitutes a solar system?

Answers

The Solar System may be divided by its components into three major regions: the inner system, the near outer system, and the far outer system. The near outer system might also be referred to as the middle system.

Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids.

Why does an ionic bond transfer electrons instead of sharing?

Answers

The modern definition of electronegativity is due to Linus Pauling. It is the power of an atom in a molecule to attract electrons to itself.

When the electronegativity difference between the two atoms is greater than 2.0, the bond is considered ionic; i.e. there is complete transfer (between the two atoms) of the electrons in the bond. The electronegativity (according to Pauling scale) of chlorine is 3.0, while the electronegativity of sodium is 0.9.

So, electrons are transferred because of a larger electronegativity difference.

When there is a whole transfer of valence electron between the atoms is called an ionic bond. In this type of bond construction, the atoms get contrarily charged.

The ionic bonds are formed due to electronegativity. According to Pauling, the capability of an atom to draw electrons towards itself is called electronegativity.

When there is a huge contrast in electronegativity between the atoms, the electrons are completely transferred between the atoms.

The atom that relinquishes an electron are called a cation and is positive whereas the atom that acquires an electron are called anions and are negatively charged.

Therefore, due to electronegativity, ionic bonds are formed.

A photon has a wavelength of 299 nm. What is the frequency of this photon?
1. 1×10^16 Hz
2. 1×10^15 Hz
3. 6.65 × 10^−37 Hz
4. 6.65 × 10^−28 Hz
5. 0.00100 Hz
6. 1.98 × 10^−31 Hz
7. 8.97 × 10^10 Hz
8. 1×10^6 Hz
9. 6.65 × 10^−18 Hz

Answers

The frequency(f) of this photon : 1 x 10¹⁵ Hz

Further explanation

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3.10⁸

λ = wavelength

A photon has a wavelength of 299 nm.

λ = 299 nm = 299 x 10⁻⁹ m = 2.99 x 10⁻⁷ m

The frequency  :

[tex]\tt f=\dfrac{3.10^8}{2.99\times 10^{-7}}\\\\f=\boxed{\bold{1\times 10^{15}~Hz}}[/tex]

A radioactive substance has a half life of 2.5 days. How much of 25.0 z is left after 10 days? ​

Answers

1.563 g

Further explanation

Given

A half life of 2.5 days ⇒ t1/2 = 2.5 days

initial sample ⇒ 25 g

duration of decay ⇒ 10 days

Analysis

Use decay Formula :

[tex]\tt Nt=No.\dfrac{1}{2}^{T/t1/2}[/tex]

Solution

[tex]\tt Nt=25.\dfrac{1}{2}^{10/2.5}\\\\Nt=25.\dfrac{1}{2}^4\\\\Nt=\boxed{\bold{1.563~g}}[/tex]

Substance left after 10 days = 1.563 g

2 The polar structure of water allows it to act as a solvent for many substances. Which of the
following statements best explains why water is considered polar?
F The unequal sharing of electrons results in the water molecule having a slightly negative
charge near its oxygen atoms and a slightly positive charge near its hydrogen atom.
G The equal sharing of electrons by the hydrogen and oxygen atoms form weak bonds that are
easily broken during dissociation.
H The unequal sharing of electrons results in the water molecule having a slightly positive
charge near its oxygen atoms and a slightly negative charge near its hydrogen atom.
The equal sharing of electrons by the hydrogen and oxygen atoms create a molecule that is
neutrally charged.

Answers

The answer would be F as oxygen is delta negative and hydrogen is slightly delta positive. Forming a permanent dipole.
