Batteries are made of two metals with different electron affinities. What does the phrase “electron affinity” mean and how does
goldfiish [28.3K]
Electron affinity is the tendency of a metal to accept electrons. In a general battery, one terminal has a higher electron affinity than the other, which attracts more electrons towards it, as compared to the other terminal. This potential difference between terminals create the voltage of the battery.

Which statement is true about a body moving at a constant speed in a circle?
Makovka662 [10]

Answer:

B

Explanation:

When something is moving at a constant velocity it's called the centripetal force. And the centripetal force accelerates radially outwards. It's like an ambulance siren. the sound waves are being exerted out into the atmosphere radiallly.

Can an object have a positive position, but a negative velocity? Explain your reasoning.
photoshop1234 [79]

Answer:

Yes

Explanation:

A position describes the position of an object relative to the x/y-axis (or the four cardinal directions). A velocity is a vector quantity, defining speed with direction.

So if an object is in a positive position, it means they are in the positive x-axis direction (or wherever on the scale the positive values are stated to be) and if it has a negative velocity, it means said object is moving in the opposite direction of the positive x-axis. It is possible for the object to still be in the positive position as it's moving with a negative velocity

How many excess electrons must be distributed uniformly within the volume of an isolated plastic sphere 23.0 cm in diameter to p
lyudmila [28]

Answer:

10573375000

216.57162\ N/C

Explanation:

k = Coulomb constant = 8.99\times 10^{9}\ Nm^2/C^2

r = Distance = \dfrac{d}{2}=\dfrac{23}{2}=11.5\ cm

E = Electric field = 1150 N/C

Electric field is given by

E=\dfrac{kq}{r^2}\\\Rightarrow q=\dfrac{Er^2}{k}\\\Rightarrow q=\dfrac{1150\times 0.115^2}{8.99\times 10^9}\\\Rightarrow q=1.69174\times 10^{-9}\ C

Number of electrons is given by

n=\dfrac{1.69174\times 10^{-9}}{1.6\times 10^{-19}}\\\Rightarrow n=10573375000

Number of excess electrons is 10573375000

r = 0.115+0.15 = 0.265 m

E=\dfrac{kq}{r^2}\\\Rightarrow E=\dfrac{8.99\times 10^9\times 1.69174\times 10^{-9}}{0.265^2}\\\Rightarrow E=216.57162\ N/C

The electric field is 216.57162\ N/C
