Answer:
a), b), d), and e) are correct.
Explanation:
c) is incorrect because an object that has a definite shape cannot be in a gaseous state as gaseous objects take the shape of their container.
a) is correct because objects that are liquid have definite volumes but no definite shapes as they take the shape of their containers,
b) is correct as this is the definition of an object which is in a solid state.
d) is correct as this is the definition of an object which is in a gaseous state.
e) is correct as rigidness, the quality of having a definite shape is only exhibited by objects that are in solid state.
There are some more like Time - second (s)
Amount of substance - mole (mole)
Electric current - ampere (A)
Temperature - kelvin (K)
Luminous intensity - candela (cd)
Answer:
Explanation:
radius of the solenoid, r = 0.05 m
length of the solenoid, l = 0.39 m
Magnetic field of the solenoid, B = 2 x 10^-5 T
Number of turns, N = 200
The magnetic field of the solenoid is given by

where, i be the current and n be the number of turns per unit length
n = N / l = 200 / 0.39 = 512.8

i = 0.031 A
It is an example of liquid. if thats what you are asking for...
