Answer:
if u go through this pdf mac\de by me few days ago, you can answer to your question perfectly, and you can know about electric circuit and others more and more.
please mark as brainliest
Please hurry Describe why electric currents can be dangerous. ***what causes it to happen in the circuit not biology****
Answer:
Basically, the main risk is cardiac arrest, caused by the electric current interfering with the normal operation of the heart muscle. Other possible damages are burns due to the electric energy vaporizing the water inside the cells, and nerve damage caused by excessive current through the nerves.
The main hazards of working with electricity are:
Electric shock and burns from contact with live parts.Injury from exposure to arcing, fire from faulty electrical equipment or installations.Explanation:

1. Why does pressure on a diver increase with
depth?
Answer:
The weight of the water above a diver exerts pressure on their body. The deeper a diver descends, the more water they have above them, and the more pressure it exerts on their body
what is Snell law of refraction????
Answer:
Snell's law of refraction also known as the second law of refraction which states:
The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant or given pair of Media .
A horizontal, uniform board of weight 125 N and length 4 m is supported by vertical chains at each end. A person weighing 500 N is hanging from the board. The
tension in the right chain is 250 N.
Which of the following describes where the person is hanging?
Answer:
let Tension in the left chain is F
here, Fnet = 0
⇒F - 500N + 250 N - 125 N = 0
⇒F - 375 N = 0
⇒F = 375 N
let r from the left end of the board is the person sitting.
now torque at left end, τ = 0.
⇒375 × (0) - 500N × (r) + 250N × (4m) - 125 N × (2m) = 0
⇒0 - 500r + 1000 - 250 = 0
⇒750 = 500r
⇒r = 750/500 = 1.5 m

Whenever an object exerts a force on another object, the second object exerts a force o the same amount, but in the ______ direction to that of the first object. (Fill in the blank)
Answer:
Opposite
Explanation:
Newton's third law of motion states that for every action there is an equal but opposite reaction.
Action-reaction force pairs make it possible for fishes to swim, birds to fly, cars to move etc,
For example, while driving down the road, a firefly strikes the windshield of a car (Action) and makes a quite obvious mess in front of the face of the driver (Reaction) i.e the firefly hit the car and the car hits the firefly.
The ultimately implies that, in every interaction, there is a pair of equal but opposite forces acting on the two interacting physical objects.
Hence, whenever any physical object exerts a force (action) on another physical object, the second physical object exerts a force (reaction) of the same amount, but acting in opposite direction to that of the first physical object.

How old are the hydrogen atoms in water?
Answer: 4.5 billion years
Explanation:
Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research.
That makes them older than the Earth, older than the solar system — even older than the sun itself.

An object whose rest mass is 2.0kg is accelerated to 0.9c. What is its relativistic mass?
Relativistic kinetic energy is KErel = (γ − 1)mc2. γ=1+1v22c2 γ = 1 + 1 v 2 2 c 2 . A binomial expansion is a way of expressing an algebraic quantity as a sum of an infinite series of terms.
Hope This Helps YouWhat causes hot spot volcanoes to form?
Answer:
A volcanic "hotspot" is an area in the mantle from which heat rises as a thermal plume from deep in the Earth. High heat and lower pressure at the base of the lithosphere (tectonic plate) facilitates melting of the rock. This melt, called magma, rises through cracks and erupts to form volcanoes.
A rookie quarter back throws a football with an initial upward velocity component of 12.0 m/s and a horizontal velocity component of 20.0 m/s. Ignore resistance. How much time is required for the football to reach the highest point of the trajectory
Answer:
t = 1.22 s
Explanation:
Given that,
The initial upward velocity component of a football = 12 m/s
The horizontal velocity component is 20 m/s
We need to find the time required for the football to reach the highest point of the trajectory. Let the time is t.
Using first equation of motion to solve it such that,
[tex]v=u+at[/tex]
u is initial velocity
v is final velocity
a = -g
so,
[tex]t=\dfrac{u}{g}\\\\t=\dfrac{12}{9.8}\\\\t=1.22\ s[/tex]
So, the required time taken by the football to reach the highest point is 1.22 seconds.

The block at Position A is released from the spring with 100 J of elastic potential energy. How
much kinetic energy does the block have at Position B? Explain how you know.
Answer:
v = 3.65 m / s
Explanation:
In this exercise we use the conservation of mechanical energy
starting point. Point A compressed spring
Em₀ = 100 J
final point. Point B uncompressed spring
Em_f = K = ½ m v²
energy is conserved
Em₀ = Em₀_f
100 = ½ m v²
v = [tex]\sqrt{ \frac{2 \ 100 }{m} }[/tex]
v = [tex]\sqrt {200/15}[/tex]
v = 3.65 m / s
