16. Solids cannot transport heat through convection. Because solids are stuck in place so they can't flow and since they can't flow, there is no convection.
17. It is because the metal conducts heat faster that it feels colder than the wood, which conducted heat slower. In other words metals are good conductors of heat. It takes away your body heat as you touch it and which makes your body temperature to drop, therefore you feel the coldness when you touch a piece of metal.
Answer:
See the anwers below
Explanation:
To solve this problem we must understand that the weight of any![W = 0.1*10\\W = 1 [N]](https://tex.z-dn.net/?f=W%20%3D%200.1%2A10%5C%5CW%20%3D%201%20%5BN%5D)
body is defined as the product of mass by gravitational acceleration. Gravitational acceleration depends on the place in space where a certain body is located.
where:
W = weight [N]
m = mass = 100 [g] = 0.1 [kg]
g = gravity acceleration [m/s²] or [N/kg]
<u>Now for the Earth</u>
<u />![W =m*g\\W =0.1*10\\W = 1[N]](https://tex.z-dn.net/?f=W%20%3Dm%2Ag%5C%5CW%20%3D0.1%2A10%5C%5CW%20%3D%201%5BN%5D)
<u />
<u>For the Moon</u>
<u />![W = m*g\\W =0.1*1.6\\W = 0.16 [N]](https://tex.z-dn.net/?f=W%20%3D%20m%2Ag%5C%5CW%20%3D0.1%2A1.6%5C%5CW%20%3D%200.16%20%5BN%5D)

Answer:
C: Variation in the value of g as the pendulum bob moves along its arc.
Explanation:
The formula for period of a simple pendulum is given by;
T = 2π√(L/g)
Where;
L is length
g is acceleration due to gravity
Now, from this period equation, it is clear that the only thing that can affect the period of a simple pendulum are changes to its length and acceleration due to gravity.
Looking at the options, the only one that talks about either the length or gravity as being potential causes of the error is option C
It can hurt and harm the body on many different and levels
