Yo sup??
the correct answer is option C ie
a material that has a low resistance and allows charges to move freely
this is a basic property shown by conductors
Hope this helps
I would say it's rationing: if people are only allowed a certain number of something (let's say: bottles of cooking oil), then the people who are entitled to is (as all are) but don't need is as much are likely to try to make profit by trying to sell it on a black market.
The answer is 1.9 m
The ideal mechanical advantage (IMA) is the ratio of input distance (ID) to output distance (OD):
IMA = ID/OD
IMA = 2
ID = ramp length = 3.8 m
OD = height = ?
2 = 3.8m/OD
OD = 3.8/2
OD = 1.9 m
The answer is 1.99 × 10⁻¹⁰ m.
To calculate this we will use De Broglie wavelength formula:
<span>λ = h/(m*v)
</span><span>λ - the wavelength
</span>h - Plank's constant: h = 6.626 × 10⁻³⁴ Js
v - speed
m - mass
It is given:
<span>λ = ?
</span>m = 9.11 × 10⁻²⁸<span> g
v = </span>3.66 × 10⁶<span> m/s
After replacing in the formula:
</span>λ = h/(m*v) = 6.626 × 10⁻³⁴ /(9.11 × 10⁻²⁸ * 3.66 × 10⁶) = 1.99 × 10⁻¹⁰ m
