Atoms ere electrically neutral because they have equal number of protons and electrons. If an atom lose or gain one or more electrons it becomes an ion.

HELP!!! HURRY DUE BY 4:30!!!

Work = force * distance.
You must produce twice as much energy as we are lifting the weight twice as high. 
But because you aren't increasing the force, you need to increase the length of the ramp instead. 
The new length will be twice as great as the previous length. 
So 8 metres is required. 

Hope this helps.

A conductor carries a current that is decreasing exponentially with time. The current is modeled as I = I0e−t/τ,where I0= 4.00 A

Whitepunk [10]

Answer:

Explanation:

Io = 4 A

τ = 0.60 s

The equation of current is given by

$I = I_{0}e^{\frac{-t}{\tau }}$

Current is defined as the rate of charge flows through the conductor

So, $\frac{dq}{dt} = I_{0}e^{\frac{-t}{\tau }}$

$\int_{0}^{q} dq = \int_{0}^{3}I_{0}e^{\frac{-t}{\tau }}dt$

$q = -4\tau \left ( e^{-\frac{t}{\tau }} \right )_{0}^{3}$

q = 2.38 C

a ball dropped from a height of 10 meters will bounce more times before coming to rest than a ball dropped from a height of 5 me

Contact [7]

Answer:

plz mark brainliest again lol :)

Explanation:

When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.

How would gravity cause planets to move if they did not have inertia?

daser333 [38]

I’d think the answer would be C. i’m just kinda guessing but my thought process is this (as simply as i can put it because physics is confusing):

so for example say you throw a ball across a flat surface. inertia is what keeps the ball rolling straight in a line, so unless you were to maybe put your hand in front of the ball or something, it would just go straight forever.

this is what happens with the planets. they go in a straight line, but since there’s gravity, the planets are also being pulled towards the sun. so gravity and inertia are why the planets orbit in the circle pattern they do. so when we remove inertia, we’re removing the state in which the planets keep going straight while being pulled towards a center point (the sun). this causes gravity to be the only factor in the planets orbiting. so that being said, the planets would just be pulled towards the sun. :)

.... is increasing the temperatures of earths oceans and atmosphere, leading to more intense storms of all types, including hurr

kirza4 [7]

I think with the increasing of temperatures of earths oceans and atmosphere is causing climate change and global warming. When the ocean heats up a lot of sea animals die and with the hot temps in the atmosphere is causing rare hot tempatures in some places in the world.
It can cause some intense storms but it mostly heats up the world and cause a lot of problems.

I hope i answered your question right.
