Bare free charges do not remain stationary when close together. To illustrate this, calculate the acceleration of two isolated p

Natali5045456 [20]

Answer:

Acceleration, $a=3.6\times 10^{16}\ m/s^2$

Explanation:

It is given that, two isolated protons are separated by 2 nm. The force due to charged particles is given by :

$F_e=\dfrac{kq^2}{d^2}$

Force due to mass of proton, $F_g=ma$

$ma=\dfrac{kq^2}{d^2}$

$a=\dfrac{kq^2}{md^2}$

$a=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{1.6\times 10^{-27}\times (2\times 10^{-9})^2}$

$a=3.6\times 10^{16}\ m/s^2$

So, the acceleration of two isolated protons is $3.6\times 10^{16}\ m/s^2$ . Hence, this is the required solution.

an athlete whirls a 7.00 kg hammer tied to the end of a 1.3 m chain in a horizontal circle the hammer moves at the rate of 1.0 r

ElenaW [278]

Answer:

The answer to your question is a = 1.3 m/s²

Explanation:

Centripetal acceleration is the motion of a body that transverse a circular path.

Data

mass = 7 kg

radius = r = 1.3 m

angular rate = w = 1.0 rev/s

centripetal acceleration = a = ?

Formula

a = rw²

Substitution

a = (1.3)(1)²

Simplification and result

a = 1.3 m/s²

Answer:

C. pressure

because heat expands and so does explosions and gravity is just gravity.

Explain how atomic interactions determine a material to be transparent and opaque?

motikmotik

Answer:

Explanation below.

Explanation:

It should be understood that transparency is caused through or by the transmission of light waves. This means that, If or when the energy known as the vibrational energy of a light wave is passed through the object, then the object appears clear, or transparent. And when or If the energy only causes vibrations in the surface before reflecting off the object, then the object will appear opaque, that is nontransparent.
