Answer:
36N
Explanation:
First draw a diagram so you can see which forces act in which direction.
Then define which is your positive direction. I chose the direction of accelleration (downward) to be positive. This means that the weight of the object is also acting in the positive direction but Tension is acting in the negative direction.
If the elevator which contains the object within is accellerating at 2.6 ms^-2 then the object and string system is also accellerating at the same rate.
F = ma where F is the resultant force.
Resultant for is Weight + Tension but tension is in the negative direction so
F = mg -T
F = 5g - T
F = ma so F = 5 x 2.6
13 = 5g-T
T = 5g - 13
T = 36N
(I've taken g = 9.8ms^-2 but if this is for a physics class I'd take it to be 9.81ms^-2)

why don't you just look on Google

Answer:
Radiation is characterized as the Emission and propogation of Energy(atomic and subatomic particles) in the form of Electromegnetic (Electric and Magnetic lines) waves through space or any medium.
Explanation:
These radiation can be in the form of heat rays , light rays, Xrays or UV rays.
Radition is bascically flow or movement of atomic particles or particularly energy in different forms. It is usually transmitted from a source to the destination for transferring Energy.
Answer:
The second arrow from the top to the bottom
Explanation:
This can be explained by the Newton's third law.
For every action there is an equal and opposite reaction.
When an object A exert a force to an object B. Then object B also excerts a force with the same size but opposite direction to object A.
Teens realize that things may be “shades of gray” after they enter Piaget’s formal operational stage. The Piaget's approach for Adolescent, also referred to asFormal operational stage is the stage in which adolescents develop their ability to think about abstract concepts, they become more argumentative and <span>indecisive.</span>
