A cause nuclear fission creates elements that are electrically charged so that way it kinda breaks the law of physics as it kinda makes energy but not entirely so it doesn’t exactly break the laws but still it’s weird. Anyways it’s A as those elements can generate energy.

Hope that helps.

A force of 100 newtons is applied to a box at an angle of 36º with the horizontal. If the mass of the box is 25 kilograms, what

notka56 [123]

Answer:

$a_x=4.944m/s^2$

Explanation:

Hello,

Based on the acting force that is applied horizontally, one can propose the following equation based on Newton's laws:

$F=ma$

Nevertheless, since we've got a angled force, it becomes:

$F=macos\theta$

In this case, $cos\theta$ accounts for the formed angle, so the horizontal acceleration turns out into:

$a_x=\frac{F}{mcos\theta}=\frac{100kg*\frac{m}{s^2} }{25kgcos(36^0)}=4.944m/s^2$

Best regads.

What is the osmotic pressure, in torr, of a 3.00% solution of NaCl in water when the temperature of the solution is 45 ºC? Enter

Anit [1.1K]

213034 torr is the osmotic pressure.

Explanation:

osmotic pressure is calculated by the formula:

osmotic pressure= iCrT

where i= no. of solute

c= concentration in mol/litre

R= Universal Gas constant

T = temp

It is given that solution is 3% which is 3gms in 100 ml.

let us calculate the concentration in moles/litre

3gm/100ml*1000ml/1L*1mol NaCl/55.84g NaCl

= 5.372 gm/litre

Putting the values in the formula, Temp in Kelvin 318.5K

osmotic pressure= 2*5.372*0.083 * 318.5 Gas constant 0.083

= 284.023 bar or 213018 torr. c= 5.372 moles/L

i=2 for NaCl

What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons? A) 6 B) 8 C) + 1 D) 12 E) 18

Oksana_A [137]

<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

Atomic mass of an atom is defined as the sum of number of neutrons and number of protons that are present in an atom. It is represented as 'A'.

Atomic number = Number of protons + Number of neutrons

We are given:

Number of protons = 6

Number of neutrons = 6

Number of electrons = 6

Atomic mass = 6 + 6 = 12

Hence, the correct answer is Option D.
