7 0

Answer:

Acceleration (a)=change in velocity/ change in time

Velocity (v)=90m/s

Time=0.0005s

a=90/0.0005

The acceleration =180000m/s^2 or 180km/s^2

Force = mass x acceleration

m=40g= 0.04kg

F= 0.04x 180000

F= 7200N or 7.2kN

Under certain circumstances, potassium ions (K ) in a cell will move across the 8.15 nm thick cell membrane from the inside to t

Verdich [7]

Answer:

$1.288\times 10^{-20}\ J$

Increase

Explanation:

q = Charge in the potassium ion = $19e-18e$

e = Charge of electron = $1.6\times 10^{-19}\ C$

$V_2-V_1$ = Change in potential = $0-(-80.5\times 10^{-3})$

Change in electric potential is given by

$E=q(V_2-V_1)\\\Rightarrow E=(19e-18e)(0-(-80.5\times 10^{-3})\\\Rightarrow E=1.6\times 10^{-19}\times 80.5\times 10^{-3}\\\Rightarrow E=1.288\times 10^{-20}\ J$

The energy is $1.288\times 10^{-20}\ J$

The potential energy will increase.

What causes resistance in an electric circuit? How is resistance measured?

Sergeeva-Olga [200]

Resistance can be caused by specific resistance tools, like resistors, or loads (the part of the component that uses the electricity) like a light bulb or a speaker. Resistance is measured in ohms and can be measured by a multimeter.
