Explanation:
some objects that are conduct :Metals conduct electricity, so if there is just the symbol of a metal, eg Mg(s), then it will conduct, even in the solid or liquid state. 2. Ionic compounds conduct when they are dissolved in water, or are melted.
what can it do ?:
A conductor is a material which electricity, heat or sound can flow through. An electrical conductor conducts electricity. ... This means that they make it very hard for electricity to flow through them. A material that stops electric current is called an insulator (electricity).
hope this helped! if not I'll answer again
Answer:
Explanation: A boy sitting on a chair.. Assuming the boy has a weight of 50N and he sits on the chair. He will exert a downward force of +50N while the chair will exert an upward force of -50N. This shows that for every action there must be equal and opposite reaction.. Another example is when you recoil a gun
Answer:
470 N.
Explanation:
Using equations of motion:
S = vi*t + 1/2*(a*(t^2))
Given:
S = 0.65 m
t = 1.5 s
vi = 0 m/s
0.65 = 1/2 * (a * (1.5)^2)
a = 1.3/2.25
= 0.578 m/s^2
Force = mass * acceleration due to gravity
= 92 * 0.578
= 53.16 N
Total force = 420 + 53.16
= 473.16 N
= 470 N.
I believe it is the first. Hope this helps!
