The answer is A i thing im not sure
Answer:
40.22 days
Explanation:
Given data:
Closest approach distance between Mars and Earth = 56 million km = 56 × 10⁶ km
Speed of the spaceship = 58000 km/h
Now, the time (t) is calculated as:
time = Distance / speed
on substituting the values, we get
t = 56 × 10⁶ km / (58000 km/h)
or
t = 965.517 hours
or
t = 965.517 / 24 days = 40.22 days
The period of any wave is the time it takes for its angle
to go from zero to 2pi .
The 'sin' function is a wave. The angle of this one is (8pi t).
When t=0, the angle is zero.
Wonderful.
Now, how long does it take for the angle to grow to 2pi ?
I*n other words, when is (8pi t) = 2pi ?
Divide each side by '2pi': . . . . . 4 t = 1
Divide each side by ' 4 ': . . . . . t = 1/4
And there you are. Every time 't' grows by 1/4, (8pi t) grows by 2pi.
So if you graph this simple harmonic motion described by 'd', you'll
see the graph wiggle up and down with a period of 1/4 .
A liquid becomes a solid when energy is removed. The energy content decreases, and the speed of the particles decrease.
Answer:
a) 
b) 
c) Towards the center of the centrifuge
Explanation:
a)
Becuse the centrifuge rotates in circular motion, there's an angular acceleration tha simulates high gravity accelerations
with r the radius and ω the amgular velocity, in or case 
so:
and g=9.8
solving for ω:
b) Linear speed (v) and angular speed are related by:
c) The apparent weigth is pointing towards the center of the circle, becuse angular acceleration is pointing in that direction.
