Water starts off its existence as a polarized molecule. a stream of water is deflected towards a nearby electrically charged object that is brought closer to it. the sign of the charge of the object a) is positive, b) is negative, c) is zero, d) can't be determined by the information given.

Option d) can not be determined from the given information

Explanation:

Water is a polar molecule consisting of 2 positive hydrogen atoms and a negative oxygen atom.

When a stream of water is deflected by positively charged object, the water molecules are oriented in such a way that oxygen  in water, being negatively charge gets attracted to the charged object and aligns near the object whereas hydrogen aligns on the opposite side overcoming the inter-atomic repulsion.

Similar is the case with hydrogen in case the object is negatively charged.

Therefore, it explains that water is a polar molecule and gets attracted to both positive and negative charges and hence, the sign of the object can not be determined.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

which three statements are true about all alloys?
