Answer : (A) A charged object is brought near a neutral object without touching it.
Explanation:
Bodies can be charged by the method of conduction. By conduction the body acquires the same charge as on the charging body.
Charging the body can be understood by the following example of charging a paper cylinder by conduction. Make a paper cylinder by rolling a strip of paper on a pencil and then gently pulling out the pencil. Suspend the paper cylinder by a string tied to its center, now touch the paper cylinder with a glass rod rubbed with silk so it has a positive charge. Remove the class rod and the again bring it near to the paper cylinder.
The paper cylinder is repelled by the positively charged rod. And when you bring a negatively rubbed rod, next to the cylinder it will be attracted towards the rod. This means that the paper cylinder has acquired a positive charge as on the glass rod due to conduction.
Answer:
So, this is not the answer because I suck like that (hehe >:3) but here's some helps.
Explanation:
1. The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below.
2. If the net force acting on an object is zero, then the object is not accelerating, and is in a state known as equilibrium.
3. This will be were you use the info I gave to figure it out. I hope this wasn't completely unhelpful.
Yeah, because of it's short frequencies, ultraviolet rays can travel through empty space- D
: D
According to the Law of Universal Gravitation, the gravitational force is directly proportional to the mass, and inversely proportional to the distance. In this problem, let's assume the celestial bodies to be restricted to the planets and the Sun. Since the distance is specified, the other factor would be the mass. Among all the celestial bodies, the Sun is the most massive. So, the Sun would cause the strongest gravitational pull to the satellite.
In a simple sentence I would say using environmental science public policy maker would be able to create policies on environmental issues such as littering,recycling specific items/reusing,not wasting excess energy,ect.
