Differences between plastic and metal​

Physics
1 answer:
beks73 [17]3 years ago
6 0

Answer:

Differences are listed below:

Explanation:

Weight: Plastic can weigh appreciably much less than than metal.A plastic part weighs approximately one-sixth of the same part in steel.

Chemical resistance:Plastic are much less likely to suffer chemical attack and don not corrode.

Machinability: Plastic are much more easier to cut through than metal.

Product life: The life span for plastic is longer than of the metals in many applications.

Cost: The cost of plastic raw materials is appreciably less than of the metals.

Heat: Plastic are less heat resistive than metals.

Ultraviolet light can degrade the plastics soon.

Strength: Metal provides more strength than the plastic.

Which of these properties is the best measure of a star's brightness? (1 point)
storchak [24]

Answer:

ABSOLUTE MAGNITUDE, C

Explanation:

Absolute magnitude is how bright the star is from a distance of 10 parsecs. Apparent magnitude is how bright the star appears from Earth, which can vary, because some stars may be farther or closer away. Age and size are not very accurate either. For example, at the end of their lifetimes, very big start may explode in a violent and bright supernova, and outshine the stars near them. As for size, as many stars several times smaller than the sun shine much brighter than it, making it inaccurate.

When three identical bulbs of 60W,200V rating are connected in series at a 200V supply the power drawn by them will be?
Law Incorporation [45]

Answer:

P = 180 [w]

Explanation:

To solve this problem we must use ohm's law, which is defined by the following formula.

V = I*R & P = V*I

where:

V = voltage = 200[volts]

I = current [amp]

R = resistance [ohm]

P = power [watts]

Since the bulbs are connected in series, the powers should be summed

P = 60 + 60 + 60

P = 180 [watts]

Now we can calculate the current

I = 180/200

I = 0.9[amp]

Attached is an image where we see the three bulbs connected in series, in the circuit we see that the current is the same for all the elements connected to the circuit.

And the power is defined by P = V*I

we know that the voltage is equal to 200[V], therefore

P = 200*0.9

P = 180 [w]
