100points plzz me a glass rod with a silk cloth is an example of charging by

question 1 options:

conduction

induction

friction

question 2 (1 point)

rubbing a glass rod with a silk cloth will cause the rod to become more because it is losing electrons and the cloth to become more charged because it is gaining electrons.

question 2 options:

negatively; positively

positively ; neutral

positively ; negatively

neutral ; negatively

question 3 (1 point)

all matter is made up of both positive and negative charges, but we can only transfer the charges.

question 3 options:

positive

hyperactive

negative

neutral

question 4 (1 point)

charging by a method used to charge an object without actually touching the object to any other charged object.

question 4 options:

conditioning

conduction

friction

induction

question 5 (1 point)

when a charged object is brought near (without touching) a neutral object, this induces the electrons within the neutral object to move. this is an example of a temporary charge by

question 5 options:

condition

conduction

induction

friction

question 6 (1 point)

grounding allows charged objects to become neutral by electrons either flowing from the earth to the object or electrons flowing from the object to the earth through a conductor.

question 6 options:

true

false

question 7 (1 point)

when an uncharged student (standing on an insulating mat) touches a negatively charged van de graaff generator, this is an example of charging by

question 7 options:

conduction

friction

induction

condition

question 8 (1 point)

a positively charged object will be repelled by a negatively charged object because the charges are different.

question 8 options:

true

false

question 9 (1 point)

which of the following is an example of static electricity?

question 9 options:

current flowing through an outlet in your home

electrons moving from the battery through the wires to a light and back to the battery.

a build up of charges on a sock from a dryer

question 10 (1 point)

according to the image below, the like charges within the metal leaves at the bottom in the glass of an electroscope will be by each other and therefore will

question 10 options:

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
