7 0

Answer:

Explanation:

Aluminium , mass no = no of proton + neutron = 27

atomic no = no of proton = 13

no of neutron = 27 - 13 = 14

Nitrogen  , mass no = no of proton + neutron = 14

atomic no = no of proton = 7

no of neutron = 14 - 7 = 7

Helium   , mass no = no of proton + neutron = 4

atomic no = no of proton = 2

no of neutron = 4 - 2= 2

fluorine    , mass no = no of proton + neutron = 19

atomic no = no of proton = 9

no of neutron = 19-9 = 10

A small styrofoam ball with a layer of metallic coating is lowered into the gap between two large metal plates. A large potentia
Brut [27]

Answer:

ball will oscillate in between the plates

Explanation:

The metallic coated styrofoam lowered in between two large metal plates, a large potential difference V is kept between the two plates, will experience a force of repulsion ( because both plates and balls will have similar kind of charges and like charges repel each other)  from the opposite plates.

If we consider d as the distance between the plates, E as electric field because of Potential difference V. Then force F experience by the ball will be

F= \frac{qV}{d}

where q be the total charge on the metallic coated ball.

clearly,  since, both the plates will repel the ball in opposite directions, hence ball will be in oscillate in between the plates.

To measure moderately low pressures, oil with a density of 9.0 x 102 kg/m3 is used in place of mercury in a barometer. A change
Yuki888 [10]

Answer:

Δ P =  13.24 Pa

Explanation:

Given that

Density of oil ,ρ₁ = 9 x 10² kg/m³

We know that density for mercury ,ρ₂  = 13.6 x 10³ kg/m³

The change in the height of column ,Δh = 1.5 mm

The pressure given as

P = ρ g h

Change in the pressure

Δ P =  ρ₁ g Δh

Now by putting the values

Δ P =  9 x 10² x 9.81 x 1.5 x 10⁻³    Pa

Δ P =  13.24 Pa

Therefor the change in the pressure will be 13.24 Pa.
