Answer: 12.6 newtons

Explanation:

Take the equation, static force equals static friction times normal force.             ( F = μn )

Divide both sides by static friction so normal force is the answer.

( F / μ = n )

Insert your numbers (4.11 F and 0.325 μ) into the equation to get your answer.

( 4.11 / 0.325 = n )

n = 12.6

My first time helping someone and future people on this site. This is the answer I put in and got right.

Explanation:

The simple definition of a covalent bond is a strong force when two atoms share one or more pairs of electrons.

Popular examples of covalent bonds would be:

Carbon Monoxide (CO)

Methane (CH_{4})

Water (H_{2} O)

What is used to measure mass?
defon

Answer:

A balance

Explanation:

Scientists measure mass with a balance, such as a triple beam balance or electronic balance. In science, the volume of a liquid might be measured with a graduated cylinder.

Imagine another solar system, with a star of the same mass as the Sun. Suppose a planet with a mass twice that of Earth (2 Earth
sashaice [31]

Answer:

Time period, T = 403.78 years

Explanation:

It is given that,

Orbital distance, a=1\ AU=1.496\times 10^{11}\ m

Mass of the Earth, m_e=5.972\times 10^{24}\ kg

Mass of the planet, m_p=2m_e=11.944\times 10^{24}\ kg

Let T is the orbital period of this planet. The Kepler's third law of motion gives the relation between the orbital period and the orbital distance.

T^2=\dfrac{4\pi^2}{Gm_p}a^3

T^2=\dfrac{4\pi^2}{6.67\times 10^{-11}\times 11.944\times 10^{24}}\times (1.496\times 10^{11})^3

T=1.28\times 10^{10}\ s

or

T = 403.78 years

So, the orbital period of this planet is 404 years. Hence, this is the required solution.

4.0 J of work are performed in stretching a spring with a spring constant of 2500 N/m. How much is the spring stretched?
earnstyle [38]

energy = elastic \: potential

4 =  \frac{1}{2} kx {}^{2}

4 =  \frac{1}{2} (2500)x {}^{2}

4 = 1250x {}^{2}

x {}^{2}  =  \frac{4}{1250}  = 0.0032 \: meters

x =  \sqrt{0.0032}  = 0.05657 \: meters

How do you calculate the speed of a 3.1eV photon and a 3.1eV electron?
-Dominant- [34]

Explanation:

We need to find the speed of a 3.1eV proton and a 3.1eV electron.

For proton, using conservation of energy such that,

\dfrac{1}{2}m_pv_p^2=eV\\\\v_p^2=\dfrac{2eV}{m_p}\\\\v_p=\sqrt{\dfrac{2eV}{m_p}}

m_p is mass of proton

v_p=\sqrt{\dfrac{2\times 3.1\times 1.6\times 10^{-19}\ J}{1.67\times 10^{-27}\ kg}}\\\\v_p=2.43\times 10^5\ m/s

For electron,

\dfrac{1}{2}m_ev_e^2=eV\\\\v_e^2=\dfrac{2eV}{m_e}\\\\v_e=\sqrt{\dfrac{2eV}{m_e}}

m_e is mass of proton

v_e=\sqrt{\dfrac{2\times 3.1\times 1.6\times 10^{-19}\ J}{9.1\times 10^{-31}\ kg}}\\\\v_e=1.44\times 10^6\ m/s

Hence, this is the required solution.
