Answer: Radio signals sent through space
Explanation:
>Radio signals are electromagnetic signals which can travel through space even in vacuum where no air is absent . Radio signals carry energy in the form of electromagnetic wave .
>Thunder heard from many miles away is due to propagation of sound wave in the air or atmosphere . The sound wave carries energy in the form of mechanical energy which can not propagate in vacuum and requires a medium .
>When nuclei of atoms split into parts they fly away from each other with some speed carrying kinetic energy which is a part of mechanical energy .
Thus mechanical energy is involved in all the given examples expect the case of radio signals sent through space.

<h3>What are infrared satellite images?</h3>
Infrared satellite images are images produced as a result of electromagnetic radiations reflected or emitted from a target surface in the infrared position of the electromagnetic spectrum.
On infrared images, the clouds emit very bright white color because of the low temperature and the land appears to be black because of the hot temperature.
Therefore, in infrared satellite images, land appears black and clouds appear white. C

Answer:
Acceleration = 0.2m/s²
Explanation:
Given the following data;
Mass = 1000kg
Force = 200N
To find acceleration;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
F represents force.
m represents the mass of an object.
a represents acceleration.
Making acceleration (a) the subject, we have;
Substituting into the equation;
Acceleration = 0.2m/s²
Answer:
Heat
Explanation:
This combo can cause weather such as tornados,hurricanes and storms.
