The patterns that can be looked for when studying science topic include the use of data or carrying out an experiment.

<h3>How to illustrate the information?</h3>

It should be noted that patterns are regular and intelligible forms or sequences that can be found in nature. Based on the information, scientific questions may be generated when scientists want to observe a pattern of events.

It should be noted that when scientists want to observe a pattern of events or

when something does not match an established pattern, scientists can use patterns to classify objects or phenomena into groups.

Therefore, the patterns that can be looked for when studying science topic include the use of data or carrying out an experiment.

A typical neutron star may have a mass equal to that of the Sun but a radius of only 20 km.(a) What is the gravitational acceler

Pepsi [2]

Answer:

$331665750000\ m/s^2$

3257806.62409 m/s

Explanation:

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

M = Mass of Sun = $1.989\times 10^{30}\ kg$

r = Radius of Star = 20 km

u = Initial velocity = 0

v = Final velocity

s = Displacement = 16 m

a = Acceleration

Gravitational acceleration is given by

$g=\dfrac{GM}{r^2}\\\Rightarrow g=\dfrac{6.67\times 10^{-11}\times 1.989\times 10^{30}}{20000^2}\\\Rightarrow g=331665750000\ m/s^2$

The gravitational acceleration at the surface of such a star is $331665750000\ m/s^2$

$v^2-u^2=2as\\\Rightarrow v=\sqrt{2as+u^2}\\\Rightarrow v=\sqrt{2\times 331665750000\times 16+0^2}\\\Rightarrow v=3257806.62409\ m/s$

The velocity of the object would be 3257806.62409 m/s

Is it better to wire a house using a series circuit or a parallel circuit?

Svetach [21]

Answer: its better to use parallel because, in parallel connection there will be more advantages than a series connection. and also the electronic devices are wired in series so thats why you should use parralel in house wiring

so its c.

because the parallel is wired through the whole house so if one of the circuits fail youŕe not screwed

The height of the mercury column in a barometer is 756 mm Hg on

notsponge [240]

Answer:

p = 1.0076 10⁵ Pa

Explanation:

Atmospheric pressure is given by the relation

P = rho g h

In this case they indicate that the height of the column of mercury is h = 756 mm Hg

let's reduce the height to the SI system

h = 756 mm (1m / 1000 mm)

h = 0.756 m

let's calculate

P = 13600 9.8 0.756

p = 1.0076 10⁵ Pa
