Answer;
Spiral galaxy
Explanation;
In a spiral galaxy, the stars, gas and dust are gathered in spiral arms that spread outward from the galaxy's center. Spiral galaxys are divided into three main types depending on how tightly wound their spiral arms are: Sa, Sb and Sc.
All spiral galaxies can broadly be described visually as having a central bulge of old stars surrounded by a flattened disk of young stars, gas and dust.
Then go to this link when you go there you will see request access sent me request saying brainly in the box the I will accept it then you watch the video up there then you then you will complete the slide that you will request for I will be posting the link to that in the chat.
Here is the directions for the slide you guys are going to be doing:
Step 1: Draw a model to show how sound is created and how you think it makes the windows move.
Step 2: Label your model with explanations. Include all of these science vocabulary/concepts: vibrations/oscillations, force, energy, and transfer.
By the way this the Brainly committee we will be testing how smart you guys are so guys prove it. If you do this right the Brainly will sent 500 brainly points into the account that answers it right. If you have any questions please ask.
Answer:
Not 500 points I got 18 but thx
Explanation:
B. It increases the potential energy of electrical charges to produce a current.
C. It increases the kinetic energy of electrical charges to produce a static discharge.
D. It transfers electrons through induction so they generate electrical energy.
Answer:
B. It increases the potential energy of electrical charges to produce a current.
Explanation:
Battery is a source of constant potential difference
When a charge is passed through the battery then its potential energy changes by
here we know that
= potential difference of battery
so as the charge is passing through the terminals of battery its potential energy is changed by above value.
Now by the conservation of energy principle we know that this change in potential energy will convert into kinetic energy of charge and then the flow of charge will produce current in the circuit.
So battery is used to maintain a constant current in the circuit by giving potential energy to the charge.
compound for health?
Answer:
Two lethal elements can combine to form an essential compound for health by undergoing a chemical reaction such that the properties of the individual elements are different from the properties of the product and are no more lethal
Example Mercury and Sulfur combine to form cinnabar which is used as a medicine to relieve pain, antiseptic, and to cure diseases
Mercury and sulfur combines because mercury readily combines with sulfur at high temperatures
Explanation:
Mercury is a lethal element that also has harmful effects on the neurological system
Sulfur is lethal when too much of it is consumed
