How do black holes grow?

MariettaO [177]

Answer:

Black holes of stellar mass are expected to form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings.

A team of scientists is working to determine if a meteor created a landform.

liubo4ka [24]

Answer:

geology , astronomy

Explanation:

The earth science is a body of knowledge that includes the fields of the all the natural science as the geology, astronomy and those relate to the planet earth and hence deals with the physical and the chemical constitution and other includes the planetary science

<u>The study of the lithosphere, hydrosphere, and the biosphere and takes a holistic view of the earth.</u>

Thus for a team of contents that are working to locates and fond out the exact cause of the meteor that led to the formation of land-forms will relate to the application of the geology and the astronomy.

A pendulum is made up of a metal cylinder of diameter d attached to a thin string. The pendulum passes through a photogate at th

ankoles [38]

The calculated total mechanical energy will reduce if the oscillation is not perpendicular to the photogate.

<h3>Mechanical energy at the lowest position of the pendulum</h3>

The mechanical energy at the lowest position of the pendulum is calculated as follows;

$U = K.E = \frac{1}{2}mv^2$

<h3>When the direction of the motion changes</h3>

let the velocity of the pendulum = vsin(θ)

when the velocity is perpendicular = vsin(90) = v

At any direction different from perpendicular direction, the mechanical energy reduces by;

$\Delta U = \frac{1}{2} mv^2 - \frac{1}{2} m(vsin\theta)^2\\\\\Delta U = \frac{1}{2} m(v^2 - v^2sin^2\theta)\\\\\Delta U = \frac{1}{2} mv^2(1 - sin^2\theta )$

Thus, the calculated total mechanical energy will reduce if the oscillation is not perpendicular to the photogate.

Why do many cooking pots and pans have wooden or plastic handles?

natali 33 [55]

They are poor conductors of heat so they will not transfer the heat from the pot to your hand
