The total resistance of electric circuit when resistors wired in a series is the sum of the individual resistance: each resistor in a series circuit has the same amount of current through and through it. Each resistor in a parallel circuit the same for voltage of the source applied to it.
when resistors are connected in parallel, the supply current is equal to the sum of the currents the metre resistor. In other words the currents in the branches of a parallel circuit add up to the supply current. When resistors are connected in parallel, they have the same potential difference is across them
Answer:
1: Elements are substances that cannot be broken down into more substances.
2: Compounds are a group of elements in a specific ratio.
3: A metalloid is between a metal and a non-metal.
4: A physical property is a property you can see or touch.
5: A chemical property is a property seen in chemical reactions.
6: Alloys are the combination of two or more metals to make a better material.
7: An insulator doesn't let heat and sound escape.
8: Corrosion is when a metal reacts to oxygen, water, or sulfur.
9: Rust is when a metal is exposed to oxygen
Explanation:
Answer:
(a) Angular speed will be 0.2512 rad/sec
(b) Radius will be 213.375 m
Explanation:
We have given time to complete 1 lap = 25 sec
We know that 1 lap =
radian
(a) So angular speed 
(B) Tangential velocity is given as v = 53.6 m/sec
We know that tangential velocity is given by

So radius 
Answer:
45
Explanation:
because you divide volume and mass
<span>Cartilage is the hard but flexible structure found in pieces of your nose and ears. It is similar to bone, but allows for flexibility and movement. When looking at skeletons, you'll notice that they don't have a nose or ears, because cartilage deteriorates much faster than bone. Cartilage is also found in elsewhere in the animal kingdom--the skeletal structure of a shark is made primarily from cartilage!</span>
