Answer:

3 Objects that carry instruments into the stratosphere to measure atmospheric conditions

Explanation:

Weather balloons are objects that carries instruments into the stratosphere to measure atmospheric conditions.

They are very important weather measuring device that helps meteorologists in their fore casts.

These balloons are specially designed for high altitudes. They carry very sensitive devices that are very useful in collecting information about temperature, precipitation, pressure e.t.c

Which has the most kinetic energy from its motion?
victus00 [196]

Answer:

option c

Explanation:

K.E=1/2mv(squared)

K.E=1/2x900x80x80

K.E=450x6400=2880000J

convert to KJ=2880000/1000=2880KJ

A circular flat coil that has N turns, encloses an area A, and carries a current i has its central axis parallel to a uniform ma
bogdanovich [222]

Answer:

Torque on the coil will be ZERO

Explanation:

As we know that the magnetic moment of the closed current carrying coil is always along its axis and it is given as

M = N i A

now we know that magnetic field is also along the axis of the coil so here as we know the equation of torque given as

\tau = \vec M \times \vec B

so we have

\tau = M B sin0

\tau = 0

Why are systems in Dynamic Equilibrium stable?
yaroslaw [1]

Answer:

Dynamic Equilibrium are stable because there is an equal rate of transition between reactants and products, or between the forward and the reverse process, in a back and forth manner, such that the net change of the concentration or system is zero, and therefore, there are no excess force factor, tending to create a different outcome

Explanation:

Dynamic equilibrium, in physics and in chemistry, is the equilibrium experienced by a system that undergoes change, where however, both the forward and the reverse effect of the change are taking place.
