Answer: drying towels at the beach.
Explanation:
Radiation simply has to do with the energy that is gotten from a particular source and then goes through some materials. It simply means the way energy is being transmitted as waves or heat through a certain medium.
From the options given, the scenario whereby a radiation takes place is when drying towels on the beach.

Answer:
The components of reaction at the fixed support are
,
,
,
,
, 
Explanation:
Looking at the diagram uploaded we see that there are two forces acting along the x-axis on the fixed support
These force are 400 N and
[ i.e the reactive force of 400 N ]
Hence the sum of forces along the x axis is mathematically represented as

=> 
Looking at the diagram uploaded we see that there are two forces acting along the y-axis on the fixed support
These force are 500 N and
[ i.e the force acting along the same direction with 500 N ]
Hence the sum of forces along the x axis is mathematically represented as

=> 
Looking at the diagram uploaded we see that there are two forces acting along the z-axis on the fixed support
These force are 600 N and
[ i.e the reactive force of 600 N ]
Hence the sum of forces along the x axis is mathematically represented as

=> 
Generally taking moment about A along the x-axis we have that

=> 
Generally taking moment about A along the y-axis we have that

=> 
Generally taking moment about A along the z-axis we have that

=> 
Answer:
positive
An atom has a even amount of protons, electrons, and a little less neutrons. If the atom lost one electron, then it now has a positive charge.

Answer:
2.5 ms^-2
Explanation:
acceleration
= (final velocity - initial velocity)/time
= [(40m/s) - (20m/s)]/8s
= (20m/s)/8s
= 5/2 m/s²
= 2.5 m/s²
= 2.5 ms^-2
Based on the scenario,
The thing that the result say about distance covered is :
it tells you that the distance covered is equal to the average speed times the travel time
hope this helps
