The lithosphere because it includes the outer region of the earth including the crust and outer mantle
Argon come from the air. It is a noble gas present in atmosphere. The percentage of argon in air is about 0.93%. Naturally, it is a colorless and odorless gas. When electrifies it gives a blue-green glow. Argon laser is used in field of medicine and surgery.
I'm going to have to go with A Magnetic because it seems to be the only one that makes sense it can't B because electron and Electrical are the same thing its not going deflect it and C it might seem right but gravity has nothing to do with deflection so I pick Magnetic.
So your answer is A.
Answer:
a)
Nm⁻¹
b)
Hz
c)
ms⁻¹
d)
m
e)
ms⁻²
f)
m
Explanation:
a)
= force required to hold the object at rest connected with stretched spring = 27 N
= stretch in the spring from equilibrium position = 0.2 m
= force constant of the spring
force required to hold the object at rest is same as the spring force , hence
inserting the values
Nm⁻¹
b)
frequency of the oscillations is given as
inserting the values
Hz
c)
= Amplitude of oscillations = 0.2 m
= angular frequency
Angular frequency is given as
rads⁻¹
Maximum speed of oscillation is given as
ms⁻¹
d)
maximum speed of the object occurs at the equilibrium position, hence
m
e)
Maximum acceleration of oscillation is given as
ms⁻²
f)
maximum acceleration occurs when the object is at extreme positions, hence
m
