Answer:

D. electron < neutron < atomic nucleus < atom

Explanation:

size of an electron = 2.82 * 10^{-15} m.

size of a neutron = 0.8 * 10^{-15} m.

size of a atomic nucleus = 1.56 *  10^{-14} m.

size of an atom  =  0.1 - 0.5 nanometers

hence if we compare the size of all components we will see size of an electron is the smallest and size of an atom is the largest.

electron < neutron < atomic nucleus < atom

Fantom [35]

Answer:

2.58 x 10⁸ m/s

Explanation:

Time dilation fomula will be applicable here, which is given below.

t = \frac{T}{\left ( 1-\frac{v^2}{c^2} \right )^\frac{1}{2}}

Where T is dilated time or time observed by clock in motion , t is stationary time , v is velocity of clock in motion and c is velocity of light .

c is 3 times 10⁸ ms⁻¹ , T is 7.24 h , t is 3.69 h. Put these values in the formula

7.24 = \frac{3.69}{\left ( 1-\frac{v^2}{c^2} \right )^\frac{1}{2}}\\

\frac{v^2}{c^2}=0.744\\\\

v=2.58\times 10^8

When holes are drilled through the wall of a water tower, water will spurt out the greatest horozontal distance from the hole cl
Mnenie [13.5K]

Bottom of the water tower

Explanation:

When holes are drilled through the wall of a water tower, water will spurt out the greatest horizontal distance from the hole closest to the bottom of the water tower.

This is because the near the bottom of the tower is the greatest compared to other parts of the tower.

  • The pressure increases with depth.
  • As the depth of water increases, the column of water above exerts more pressure on the one below.
  • Therefore, water will spurt out more from the bottom of the tower compared to the top of the tower.

A racing car’s velocity is increased from 44 m/s to 66 m/s in 11 seconds. What is the acceleration? and what is the displacement
Musya8 [376]

Answer:

Explanation:

Acceleration is defined as the change in velocity per unit of time

Acceleration (a) = ΔV/t

V = Velocity      t = time

ΔV = V₂ - V₁      t = 11s

V₁ = 44m/s

V₂ = 66m/s

ΔV = 66 - 44

     = 22m/s

Acceleration (a) = 22/11

                          = 2m/s²

Displacement (d): Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time.

d = v₀ + 1/2*at²

v₀ = 44m/s

a = 2m/s

t = 11s

d = 44 + 1/2*(2 x 11²)

  = 44 + 121

d = 165m
