Answer:

Part a)

$M = 2.31 \times 10^{30} kg$

Part b)

$M = 1.15 M_s$

Explanation:

Part a)

As we know that the period of revolution of the planet is given by

$T = 2\pi\sqrt{\frac{r^3}{GM}}$

now we know that

$r = 10.5 \times 10^6 km = 1.05 \times 10^{10} m$

T = 6.3 days

$T = 5.44 \times 10^5 s$

now we have

$5.44 \times 10^5 = 2\pi\sqrt{\frac{(1.05\times 10^{10})^3}{(6.67 \times 10^{-11})M}}$

$M = 2.31 \times 10^{30} kg$

Part b)

As we know that mass of sun is given as

$M_s = 2.0 \times 10^{30} kg$

now we have

$\frac{M}{M_s} = \frac{2.31 \times 10^{30}}{2 \times 10^{30}}$

$M = 1.15 M_s$

Two parallel plates have an area of

Murrr4er [49]

Answer:

8.85

Explanation:

The computation of the charge that must place on them in order to create 1000 N/C field between the plates is shown below:

We know that

E = (Q/A) ÷ E_o

1000 = Q ÷ 0.01×8.85× 10^-12

Q = 8.85 × 10^-12

So,

The answer is 8.85

The above formula should be applied so that the correct value could come

Electrical wires suspended between two towers form a catenary (see figure) modelled by the equation shown below, where x and y a

RideAnS [48]

Given that the arc length is:
s = ∫ √[1² + (dy/dx)²] dx

So arc length between the two points is then: 
s = 2*20sinh(x/20)
= 40sinh(x/20) 

The straight distance between the two points is : d = 2x 
So, x = d/2.
= 40/2
= 20 m 

Plug this into the arc length equation to get:
s = 40sinh[20/20)]
=40* ½ (e - 1/e) 
 = 47 m

A racing car’s velocity is increased from 44 m/s to 66 m/s in 11 seconds. What is the acceleration? and what is the displacement

Musya8 [376]

Answer:

Explanation:

Acceleration is defined as the change in velocity per unit of time

Acceleration (a) = ΔV/t

V = Velocity t = time

ΔV = V₂ - V₁ t = 11s

V₁ = 44m/s

V₂ = 66m/s

ΔV = 66 - 44

= 22m/s

Acceleration (a) = 22/11

= 2m/s²

Displacement (d): Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time.

d = v₀ + 1/2*at²

v₀ = 44m/s

a = 2m/s

t = 11s

d = 44 + 1/2*(2 x 11²)

= 44 + 121

d = 165m
