Answer:

Explanation:

as the copper wire is very dangerous so now if these two thing happens then it would easily help the current flows through it so it might be a little bit easy for the current to flow through it

Deimos's Orbit. Deimos orbits Mars at a distance of 23,460 km from the center of the planet and has a period of 1.263 days. Assu

mihalych1998 [28]

Answer:

M = 5.882 10²³ kg

Explanation:

Let's use Newton's second law to analyze the satellite orbit around Mars.

F = m a

force is universal attraction and acceleration is centripetal

a = v²/ R

the modulus of velocity in a circular orbit is constant

v= d/T

the distance of the cicule is

d =2pi R

a = 2pi R/T

we substitute

- G m M / R² = m ( $- \frac{4\pi^2 R^2 }{T^2 R}$ )

G M = $\frac{ 4\pi ^2 R^3 }{T^2 }$

M = $\frac{4 \pi ^2 R^3 }{ G T^2 }$

the distance R is the distance from the center of the planet Mars to the center of the satellite Deimos

R = 23460 km = 2.3460 10⁷ m

the period of the orbit is

T = 1,263 days = 1,263 day (24 h / 1 day) (3600s / h)

T = 1.0912 10⁵ s

let's calculate

M = $\frac{4 \pi ^2 ( 2.3460 \ 10^7)^3 }{5.67 10^{-11} \ (1.0912 \ 10^5)^2 }$

M = 509.73418 10²¹ /8.66640 10⁻¹

M = 58.817 10²² kg

M = 5.882 10²³ kg

A 60-kg skate boarder is standing on his stationary board. A bigger, out of control 75-kg skate boarder crashes into him with a

andrezito [222]

Answer:

2.22m/s

Explanation:

Given parameters:

M1 = 60kg

M2 = 75kg

V1 = 0m/s

V2 = 4m/s

Unknown;

Velocity after collision = ?

Solution:

To solve this problem, we must understand that the momentum before and after collision of the bodies must be the same;

M1 V1 + M2 V2 = v(M1 + M2)

So;

60 x 0 + 75 x 4 = v (60 +75)

300 = 135v

v = 2.22m/s
