A spacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1 480 kg. It has strayed too

maks197457 [2]

Answer:

2352645198509.9604 m/s²

Explanation:

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

M = Mass of black hole = $90\times 1.989\times 10^{30}\ kg$

$R_{f}$ = 10000+100 m

$R_{sb}$ = Distance between the nose and the center of the black hole = 10000 m

The difference in the gravitational field in this system is given by

$\Delta F=\dfrac{GMm}{R_{f}^2}-\dfrac{GMm}{R_{sb}^2}\\\Rightarrow \Delta g=GM\left(\frac{1}{R_f^2}-\frac{1}{R_{sb}^2}\right)\\\Rightarrow g=6.67\times 10^{-11}\times 90\times 1.989\times 10^{30}\left(\frac{1}{(10000+100)^2}-\frac{1}{10000^2}\right)\\\Rightarrow \Delta g=-2352645198509.9604\ m/s^2$

The acceleration is 2352645198509.9604 m/s²

Toby's Trucking Company determined that on an annual basis, the distance traveled per truck is normally distributed, with a mean

Reptile [31]

Answer: 56994 miles

Explanation:

Given : Toby's Trucking Company determined that on an annual basis, the distance traveled per truck is normally distributed with

$\mu=50,000\text{ miles}$

Standard deviation : $\sigma=12,000\text{ miles}$

Let a be the distance traveled by at least 72% of the trucks.

Let X be the random variable that represents the distance traveled by a truck

Then $P(x\geq a)=0.72$

The critical value corresponds to p-value 0.72 : $z=0.5828415$

Also, $z=\dfrac{x-\mu}{\sigma}$

$\Rightarrow\ 0.5828415=\dfrac{a-50000}{12000}\\\\\Rightarrow\ a=12000(0.5828415)+50000=56994.098\approx56994$

Hence, 56994 miles will be traveled by at least (equal to and more than) 72% of the trucks .

The height of the mercury column in a barometer is 756 mm Hg on

notsponge [240]

Answer:

p = 1.0076 10⁵ Pa

Explanation:

Atmospheric pressure is given by the relation

P = rho g h

In this case they indicate that the height of the column of mercury is h = 756 mm Hg

let's reduce the height to the SI system

h = 756 mm (1m / 1000 mm)

h = 0.756 m

let's calculate

P = 13600 9.8 0.756

p = 1.0076 10⁵ Pa
