Hey there!
To solve this question, lets convert 108 km/h into meters per second.
1 km/h is equal to 0.277778 m/s
To convert 108 km/h into m/s, we just multiply 0.277778 by 108.
0.277778 × 108 = 30.000024
So, the train is travelling at approximately 30 meters per second.
Thank you!
Within each layer temperature either goes up (in the stratosphere and thermosphere) or down (in the troposphere and mesosphere). Boundaries "pauses<span>" between layers are defined by where temperature stays about the same with height.
Hope this helps!

Question:
What two forces are balanced in what we call gravitational equilibrium?
A) the electromagnetic force and gravity
B) outward pressure and the strong force
C) outward pressure and inward gravity
D) the strong force and gravity
E) the strong force and kinetic energy
Answer:
The correct answer is C) Outward Pressure and Inward gravity
Explanation:
Gravitational equilibrium is a balance between the inward pull of gravity and the outward push of internal gas pressure. It also refers to the condition of a star in which the weight of overlying layers at each point is balanced by the total pressure at that point.
As the weight increases in the lower layers of the sun, the pressure also increases to maintain this balance. So you find that the outward push of pressure balances the inward pull of gravity thus creating an equilibrium.
Why is gravitational equilibrium important?
The simple answer is <u>balance. </u> If for instance the sun as a stable star (which has gravitational equilibrium) loses it's balance, it becomes highly unstable and prone to violent outbursts. These outbursts are caused by the very high radiation pressure at the star's upper layers, which blows significant portions of the matter at the "surface" into space during eruptions that may rage for several years. Of course such a condition is adverse to the existence and support of life.
Cheers!
Answer:
The current in the second wire is 8.33 A and the two currents are flowing in the opposite directions
Explanation:
Given that,
The separation between two long parallel wires, d = 2.5 cm
The force per unit length that each wire exerts on the other is, 
The current in one wire, 
(a) The force per unit length of the wire is given by :
On putting all the values we get :
So, the current in the second wire is 8.33 A.
(b) It is given that, both the wires repel each other, so the current in other wire is flowing in the opposite direction of the current in the first wire.
Hence, this is the required solution.
