Answer:

La fuerza magnética del electrón es 6.41x10⁻¹³ N.

Explanation:

Podemos encontrar la fuerza magnética (F) usando la ley de Lorentz:

F = qv\times B

En donde:

q: es la carga del electrón = 1.602x10⁻¹⁹ C

v: es la velocidad del electrón = 5x10⁶ m/s

B: es el campo magnético = 0.8 T

F = qv\times B = 1.602 \cdot 10^{-19} C*5\cdot 10^{6} m/s*0.8 T = 6.41 \cdot 10^{-13} N                                

Por lo tanto, la fuerza magnética del electrón es 6.41x10⁻¹³ N.

Espero que te sea de utilidad!

ASAP answer right and I will do a giveaway
Olenka [21]

Explanation:

Ans 1 ) As the gravity of a planet increases, there will be increase in thickness of atmosphere around that planet. The gravitational force of the planets holds the bulks of molecules of atmosphere (as gas will need higher escape velocity).

Ans 2) Mars is the easier planets among all other planets in our solar system as it lies in habitable zone and it as a moderate gravity (where live can survive). Well, there's lot of resources too.

6 An infinite non-conducting sheet has a surface charge density o = 5.80pC/m². (a) How
Anit [1.1K]

a. Work done = 2. 0648 Joules

b. Electrical potential, V = 4. 03 × 10^10 volts

<h3>How to determine the parameters</h3>

a. Work done = force × distance

Force = density × acceleration due to gravity

Force = 5. 80 × 10

Force = 58 Newton

We have that distance = 3. 56cm = 0. 0356 m

Work done = 58 × 0. 0356

Work done = 2. 0648 Joules

b. The formula for electric potential is given thus,

Electric potential, V = k\frac{q}{r}

r = 0. 0356m

k = Coulomb's constant = 8.98*10^9kg⋅m3⋅s−4⋅A−2.

q= 1.60x10^-¹C

substitute into the formula

Electric potential, V = 8. 98 × 10^9 × \frac{1. 6 * 10^-^-1}{0. 0356}

Electric potential, V = 8. 98 * 10^9 × 4. 494

Electric potential, V = 4. 03 * 10^1^0 volts

A student has 67-cm-long arms. What is the minimum angular velocity (in rpm) for swinging a bucket of water in a vertical circle
choli [55]

Answer:

29.61 rpm.

Explanation:

Given,

student arm length, l = 67 cm

distance of the bucket, r = 35 m

Minimum angular speed of the bucket so, the water not fall can be calculated by equating centrifugal force with weight.

Now,

mg = m r \omega^2

\omega = \sqrt{\dfrac{g}{R}}

R = 67 + 35 = 102 cm = 1.02 m

\omega = \sqrt{\dfrac{9.81}{1.02}}

\omega = 3.101\ rad/s

\omega = \dfrac{3.101}{2\pi} = 0.494\ rev/s

\omega = 0.494 \times 60 = 29.61\ rpm

minimum angular velocity is equal to 29.61 rpm.
