F - False.

The nucleus of an atom is positively charge.
Ivahew [28]3 years ago
3 0

Answer:

FALSE

Explanation:

Nucleus of an atom consist of neutrons and protons and it is the smallest part of atom.

So the total charge on the nucleus is due to charge of protons as we know that neutrons are neutral in nature and they do not have any charge on it.

So we will have

Q_{proton} = + 1.6 \times 10^{-19} C

Q_{neutron} = 0 C

Q_{electron} = - 1.6 \times 10^{-19} C

so here we can say that total charge on a nucleus must be positive charge which is only due to protons present inside the nucleus.

Which is not true of the Intertropical Convergence Zone?A) It features heavy precipitation B) It's where the trade winds collide
olasank [31]
<h2>Answer: C) It's a high-pressure zone with sinking air</h2>

Explanation:

The intertropical convergence zone is the region of the terrestrial globe where the trade winds of the northern hemisphere converge with those of the southern hemisphere.  

It is characterized by being <u>a belt of low pressure</u> and inconsistent location around the equator constituted by ascending air currents, where large masses of warm and humid air converge from the north and south of the intertropical zone.  

The reason of its inconsistent location is due to the movements of the Earth with the seasons, having as a consequence the amount variation of heat energy from the sun in this region.

kipiarov [429]

Answer:

1.04 s

Explanation:

The computation is shown below:

As we know that

t = t' × 1 ÷ (√(1 - (v/c)^2)

here

v = 0.5c

t = 1.20 -s

So,

1.20 = t' × 1 ÷ (√(1 - (0.5/c)^2)

1.20 = t' × 1 ÷ (√(1 - (0.5)^2)

1.20 = t' ÷ √0.75

1.20 = t' ÷ 0.866

t' = 0.866 × 1.20

= 1.04 s

The above formula should be applied

borishaifa [10]

Answer:

13 blocks

Explanation:

The total distance the student travels is 13 blocks.

 Distance is the length of path covered during the motion of a body.

 To find distance:

 Total distance  = Number of blocks to the west + number of blocks to the north + number of blocks to the east

 Total distance  = 3blocks + 4blocks + 6blocks  = 13blocks
