Strike441 [17]

Answer:

d. This statement is false. She and the Space Station share the same orbit and will stay together unless they are pushed apart.

Explanation:

In astronomy, orbit is simply a path of an object around another object in a space. That is, orbit is a path of a body that revolves around a gravitating center of mass. Examples of an orbit is are satellite around a planet, orbit around a center of galaxy, planet around the sun, and among others.

On the other hand, space station refers to a spacecraft that can support a group of human for long time in the orbit. Another names for space stations are orbital space station and orbital station.

Therefore, an astronaut goes on a space walk outside the Space Station shares the same orbit with the space station and they will stay together unless they are pushed apart.

In an engine, a piston oscillates with simple harmonic motion so that its position varies according to the expression x= 5.0 cos

lakkis [162]

Answer:

a) x = 4.33 m , b) w = 2 rad / s , f = 0.318 Hz , c) a = - 17.31 cm / s²,

d) T = 3.15 s, e) A = 5.0 cm

Explanation:

In this exercise on simple harmonic motion we are given the expression for motion

x = 5 cos (2t + π / 6)

they ask us for t = 0

a) the position of the particle

x = 5 cos (π / 6)

x = 4.33 m

remember angles are in radians

b) The general form of the equation is

x = A cos (w t + Ф)

when comparing the two equations

w = 2 rad / s

angular velocity and frequency are related

w = 2π f

f = w / 2π

f = 2 / 2pi

f = 0.318 Hz

c) the acceleration is defined by

a == d²x / dt²

a = - A w² cos (wt + Ф)

for t = 0 , we substitute

a = - 5,0 2² cos (π / 6)

a = - 17.31 cm / s²

d) El period is

T = 1/f

T= 1/0.318

T = 3.15 s

e) the amplitude

A = 5.0 cm

inysia [295]

Answer:

PRO'S OF SOLAR ENERGY: reduced electricity bills, low maintenance cost, renewable energy source.

CONS OF SOLAR ENERGY: Cost, relies on weather, takes up a lot of space.

PROS OF WIND ENERGY: Clean environment, cost effective, Free

CON'S OF WIND ENERGY: Wind turbines are noisy, strength of wind is not always reliable

PROS OF GEOTHERMAL ENERGY: Save about 30% - 60% on heating and cooling, not weather dependent.

CONS OF GEOTHERMAL ENERGY: Greenhouse emission, high investment cost, requires a lot of land.

PROS OF BIOMASS ENERGY: Reduced dependence on fossil fuels, carbon neutral, waste reduction.

CONS OF BIOMASS ENERGY: Emissions, deforestation. cost.

PROS OF HYDROELECTRIC ENERGY: Good for the environment, reliable, efficient.

CONS OF HYDROELECTRIC ENERGY: Expensive, not always safe, you can't place hydroelectric energy anywhere you want.

Mama L [17]

The distance is 20 miles

Explanation:

Definitions:

Distance is the total length of the path covered by an object during its motion, regardless of the direction of its motion
Displacement is the shortest distance between the initial and final position of the motion, so it also takes into account the direction of motion

In this problem, we want to know the distance covered by the woman. The motion consists of the following parts:

$d_1 = 10 miles$ north
