Answer:

a. $F=7.83\times 10^{-51} N$

b.Attractive

Explanation:

We are given that

$F=\frac{GM_1M_2}{R^2}$

$G=6.67\times 10^{-11} Nm^2/kg^2$

Mass of an electron, $M_1=9.11\times 10^{-31} kg$

Mass of proton, $M_2=1836\times 9.11\times 10^{-31} kg$

Distance between electron and proton,R= $3.602nm=3.602\times 10^{-9} m$

$1nm=10^{-9} m$

a.Substitute the values then we get

$F=\frac{6.67\times 10^{-11}\times 9.11\times 10^{-31}\times 1836\times 9.11\times 10^{-31}}{(3.602\times 10^{-9})^2}$

$F=7.83\times 10^{-51} N$

b.We know that like charges repel to each other and unlike charges attract to each other.

Proton and electron are unlike charges therefore, the force between proton and electron is attractive.

lidiya [134]

Answer: $197.40\ m$

Explanation:

Given

final velocity at takeoff $v=28.1\ m/s$

Acceleration of the plane can be $a=2\ m/s^2$

Initial velocity is zero for the plane i.e. $u=0$

Using the equation of motion

$\Rightarrow v^2-u^2=2as\quad [\text{s=displacement}]\\\text{Insert the values}\\\Rightarrow (28.1)^2-0=2\times 2\times s\\\\\Rightarrow s=\dfrac{789.61}{4}\\\\\Rightarrow s=197.40\ m$

Thu,s the minimum length must be $197.40\ m$

Calculate the resistance of the 1000 W microwave oven that gets plugged into a 110 v outlet

alekssr [168]

The resistance of the 1000 W microwave oven that gets plugged into a 110 v outlet will be 10 ohms.

<h3>What is resistance?</h3>

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The given data in the problem is;

P is the power= 1000 W

V is the voltage= 110 V

I is the current

R is the resistance

The resistance is found by the formula;

$\rm P = \frac{V^2}{R} \\\\ \rm R = \frac{V^2}{P} \\\\ R = \frac{(100)^2}{10000} \\\\ R= 10\ ohm$

Hence, the resistance value will be 10 ohms.
