At what distance (in m) is the electrostatic force between two electrons equal to the weight of one?
Ksivusya [100]

Answer:

Explanation:

Given

Electrostatic force between two electrons is equal to weight of one electron

i.e.

\frac{kq_1q_2}{r^2}=m_e\cdot g

where q_1,q_2 are the charge of particles

m_e=mass of electron

r=distance between them

\frac{9\times 10^{9}\times 1.6\times 10^{-19}\times 1.6\times 10^{-19}}{r^2}=9.11\times 10^{-31}\times 9.8

r=5.08\ m

If the rifle is stopped by the hunter's shoulder in a distance of 3.23 cm, what is the magnitude of the average force exerted on
never [62]

By conservation of momentum, the initial recoil speed of the rifle is: 
u = 904kg * 0.0106 kg / 3.53 kg = 2.7146 m/s 

The final recoil speed v is zero in a distance of d = 0.0346 m 

So the rifle's acceleration is a = (0 - u^2) / 2*d = -2.7146^2 / 2*.0323 m/s^2 
a = -114.07m/s^2

Digital thermometers often make use of thermistors, a type of resistor with resistance that varies with temperature more than st
Nezavi [6.7K]

Answer:

The temperature coefficient of resistivity for a linear thermistor is 1.38\times10^{-3}^{\circ}C^{-1}

Explanation:

Given that,

Initial temperature = 0.00°C

Resistance = 75.0 Ω

Final temperature = 525°C

Resistance = 275 Ω

We need to calculate the temperature coefficient of resistivity for a linear thermistor

Using formula for a linear thermistor

R=R_{0}(1+\alpha\Delta T)

R=R_{0}+R_{0}\alpha\Delta T

\alpha=\dfrac{R-R_{0}}{R_{0}\Delta T}

Put the value into the formula

\alpha=\dfrac{275-75}{275\times(525-0)}

\alpha=1.38\times10^{-3}^{\circ}C^{-1}

Hence, The temperature coefficient of resistivity for a linear thermistor is 1.38\times10^{-3}^{\circ}C^{-1}
