Answer:

Every object in space exerts a gravitational pull on every other.

Explanation:

gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit. It can also cause life-destroying asteroids to crash into planets.

Consider a single turn of a coil of wire that has radius 6.00 cm and carries the current I = 1.50 A . Estimate the magnetic flux

Fofino [41]

Answer:

$\phi = 1.78 *10^{-7} \ Weber$

$L = 1.183 *10^{-7} \ H$

Explanation:

From the question we are told that

The radius is $r = 6 \ cm = \frac{6}{100} = 0.06 \ m$

The current it carries is $I = 1.50 \ A$

The magnetic flux of the coil is mathematically represented as

$\phi = B * A$

Where B is the magnetic field which is mathematically represented as

$B = \frac{\mu_o * I}{2 * r}$

Where $\mu_o$ is the magnetic field with a constant value $\mu_o = 4\pi * 10^{-7} N/A^2$

substituting value

$B = \frac{4\pi * 10^{-7} * 1.50 }{2 * 0.06}$

$B = 1.571 *10^{-5} \ T$

The area A is mathematically evaluated as

$A = \pi r ^2$

substituting values

$A = 3.142 * (0.06)^2$

$A = 0.0113 m^2$

the magnetic flux is mathematically evaluated as

$\phi = 1.571 *10^{-5} * 0.0113$

$\phi = 1.78 *10^{-7} \ Weber$

The self-inductance is evaluated as

$L = \frac{\phi }{I}$

substituting values

$L = \frac{1.78 *10^{-7} }{1.50 }$

$L = 1.183 *10^{-7} \ H$

The cable holding a 2125 kg elevator has a maximum strength of 21,750 N. What is the maximum upward acceleration the cable can g

vivado [14]

Answer:

10.23m/s^2

Explanation:

GIven data

mass of elevator = 2125 kg

Force= 21,750 N

Required

The maximum acceleration upward

F= ma

a= F/m

a=21,750/2125

a= 10.23m/s^2

Hence the acceleration is 10.23m/s^2

Find the magnitude of the electrostatic force between a Na+ ion and a Cl− ion separated by 0.46 nm. N (b) Would the answer chang

adell [148]

Answer:

electrostatic force = 1.08 × $10^{-9}$ N

and if sodium ion replace by Li+ and chloride by Br− then there will be no change in electrostatic force

magnitude of electrostatic force will be same

Explanation:

given data

separation d = 0.46 nm = 4.6 × $10^{-10}$ m

to find out

electrostatic force between Na+ and Cl− ion

and if sodium ion replace by Li+ and chloride by Br−

solution

we know electrostatic force formula that is

electrostatic force = K ×Q1×Q2 / d² .........................1

here k is coulombs constant that is = 9 × $10^{9}$ and Q1 and Q2 is

charge that is Q1 = + 1.6 × $10^{-19}$ C

and Q2 = - 1.6 × $10^{-19}$ C

so put all these value in equation 1

electrostatic force = K ×Q1×Q2 / d²

electrostatic force = 9 × $10^{9}$ ×1.6 × $10^{-19}$ × -1.6 × $10^{-19}$ / (4.6 × $10^{-10}$ )²

so electrostatic force = 1.08 × $10^{-9}$ N

and if sodium ion replace by Li+ and chloride by Br− then there will be no change in electrostatic force

so magnitude of electrostatic force will be same
