Please explain.Are there any evidence for the existence of an object with no charge?
You mean the ';neutron';? Google it.Are there any evidence for the existence of an object with no charge?
Duality is a constant theme in this existence. Everything has its opposite. This difference is what you call a charge. All matter has anti-matter for example. The universe sometimes achieves relative neutralization. A Neutron or an Neutrino can be considered neutral, but only relatively. When you say no charge, you imply zero charge. True zero, just like infinity, is a concept that has not been observed, but only theorized.
I am under the impression that neutrons have no charge. I am unsure about what actual evidence there is. if that helps

Can a small amount of blood on an inanimate object transmit Hep B?
Can a small amount of blood on an inanimate object transmit Hep B?Can a small amount of blood on an inanimate object transmit Hep B?
Hep B is transmitted through blood and body fluids. The ways in which it can be transmitted are direct blood-to-blood contact, unprotected sex, unsterile needles, from an infected mother to her baby during childbirth, from tattooing, body piercing or acupuncture with infected needles, razors, toothbrushes, earrings or other personal items that may come in contact with blood. It's hep A that's transmitted through the fecal-oral route.
The hep B virus can live up to 4 days in the blood on an inanimate object.Can a small amount of blood on an inanimate object transmit Hep B?
hep B is not blood borne, hep C is. hep B is contracted thru the fecal oral route (when people don't wash their hands, then handle your food)
if it gets wet, and is already contaminated, there's every possibilty.
yes absolutely. that's why sterilization is so important

An object moves uniformly around a circular path of radius .20 meters, making one complete revolution every 2.
An object moves uniformly around a circular path of radius .20 meters, making one complete revolution every 2.00 sec. What are (a) the translational speed of the object, (b) the frequency of the object, and (C) the angular speed of the object?An object moves uniformly around a circular path of radius .20 meters, making one complete revolution every 2.
r = .2m and T = 2s
v = 2pi(r) / T
a) so just plug in.
b) f = 1/T so just plug in again
c) omega = v/r so just plug in.liquid color try itch cream

How does an electrically polarized object differ from an electrically charged object?
polar just means the electrons are most likely to be found in one area causing a partial charge at that end. The overall net charge may be zero. A charged object has got an abundance of electrons so that the whole object has a net charge.
When does kinetic energy = energy of the object at position x?
1/2 mv^2 = 1/2 kx^2 ?
When does that ever happen for an object attached to a spring. Here ';x'; is denoted as the distance the object travelled from ';x_0'; - the distance that the spring releases itself but does no work (potential energy)?When does kinetic energy = energy of the object at position x?
There are two equations that you need
1) 1/2 mv^2 = 1/2 kx^2
which is the one you provide and
2) 1/2 mv^2 + 1/2 kx^2 = 1/2 mvo^2
which is the total energy of the object (constant) where vo is the initial velocity of the object right before it touches the spring. 1) and 2) are then two equations with two unknowns so go ahead and solve for v and x. I would suggest you solve for v^2 and x^2 first, that would make it easier to simplify.

An object falls 9m in the first second, 27m in the second second and 108 in the third second. 5 seconds?
= 3240
0 - 1 sec =9m
9m * 3 = 27m
1 - 2 sec = 27m
27m * 4 = 108m
2 - 3 sec = 108m
108m * 5 = 540m
3 - 4 sec = 540m
540 * 6 = 3240m
4 - 5 sec = 3240An object falls 9m in the first second, 27m in the second second and 108 in the third second. 5 seconds?
It must be on another planet.
On earth, the formula is d=gt虏/2 , so after 3 sec, the fall will be 44m.
But on Jupiter, maybe...
The sequence between the first figures is 9, 27, 108
That is to say 9, 9x3, 9x3x4
The next term (4 sec) should be 9x3x4x5 = 540m
And the 5th term ( 5 sec) 9x3x4x5x6 = 3240m !!!
This does not respect the rule of the fall of objects anywhere, even on a planet with a very high gravity, except if there is an initial speed...An object falls 9m in the first second, 27m in the second second and 108 in the third second. 5 seconds?

How do size and distance affect an object's mass?
Okay... I am really confused looking for a clear answer.... HELP!!! Thank you....How do size and distance affect an object's mass?
easy: they don't.
are you sure you typed your homework in correctly?How do size and distance affect an object's mass?
Size and distance will affect an objects attraction, not its mass.
They have absolutely no effect on the mass at all.
Think like this.
If I am right next to you do I weigh more then when I am 1 mile away?
Of course not. I always weigh the same or am made out of the same quantity of stuff. Distance has no bearing.
Distance wouldn't.
Size maybe.
Obviously if you had an object of 10kg that were of the same density of an object of 20kg, then the 20kg object would have more mass.
your question is a little vague. but size governs an objects mass and how much gravity it excerts on other external bodies. distance is relevent to mass in that an object say for demonstration purposes 1000 miles away from an object the size of a skyscraper will be pulled towards it , if the same object at 1000 miles is this next time next to an object which is the size of a car is has less mass so will have less gravitational pull. but then saying this you have to consider density of the objects.
