Answer:

It remains the same

Explanation:

Atomic number is the number of protons in a nucleus so no effect due to change of neutrons.

An object initially at rest experiences an acceleration of 0.281 m/s2 to the South for a time of 5.44 seconds. It then increases
andre [41]

Answer:

12.0 meters

Explanation:

Given:

v₀ = 0 m/s

a₁ = 0.281 m/s²

t₁ = 5.44 s

a₂ = 1.43 m/s²

t₂ = 2.42 s

Find: x

First, find the velocity reached at the end of the first acceleration.

v = at + v₀

v = (0.281 m/s²) (5.44 s) + 0 m/s

v = 1.53 m/s

Next, find the position reached at the end of the first acceleration.

x = x₀ + v₀ t + ½ at²

x = 0 m + (0 m/s) (5.44 s) + ½ (0.281 m/s²) (5.44 s)²

x = 4.16 m

Finally, find the position reached at the end of the second acceleration.

x = x₀ + v₀ t + ½ at²

x = 4.16 m + (1.53 m/s) (2.42 s) + ½ (1.43 m/s²) (2.42 s)²

x = 12.0 m

How do igneous rocks differ from each other.
olya-2409 [2.1K]
Although hand specimen identification is some what of an art; igneous rocks are classified using two critiria:
•Texture
•Chemical and mineral composition
Most of the time the rock name, such as basalt or granite, reflects the chemical composition. The minerals and textures are used as adjectives that modify the rock name. You might see a name like an olivine basalt or a quartz porphyry rhyolite.

What is the function of concrete shielding in a nuclear reactor?*
Reptile [31]

The function of concrete shielding in a nuclear reactor is: <u>to contain radiation.</u>

<u>Explanation</u>:

The reactor core in the nuclear reactor is placed in a steel pressure vessel. The steel vessel is then shielded by a thick layer of concrete. The concrete shielding is done to protect the workers from radiation.

The nuclear power station must be built on hard solid rock as the reactor is heavy in structure. The radiation emitted from the reactor may harm the human being. To avoid this, the concrete shield is made to prevent the emission of radiation.
