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
Answer:
Mostly yes
Explanation:
But you should consider,brand value, material used and lasting of the equipment also
HP stands for horsepower
It's mostly used in pumps
If you can observe, we are only given one parameter here which is the time. If you want to compute for the distance, you have to know the speed. The hint here is the 'radio transmissions'. All the information gathered by the probe from the space, is sent back to the Earth by electromagnetic waves. Hence, we must know the speed of electromagnetic waves. Since they are as fast as light, their speed is equal to 300 million meters per second. Then, we can finally determine the distance.
d = speed*time
d = (300×10⁶ m/s)(2.53 hours)
Since 1 hour = 3,600 seconds,
d = (300×10⁶ m/s)(2.53 hours)(3,600 seconds/1 hour)
d = 2.73×10⁻¹² m
Answer:
13.7m
Explanation:
Since there's no external force acting on the astronaut or the satellite, the momentum must be conserved before and after the push. Since both are at rest before, momentum is 0.
After the push
Where 
is the mass of the astronaut, 
is the mass of the satellite, 
is the speed of the satellite. We can calculate the speed 
of the astronaut:
So the astronaut has a opposite direction with the satellite motion, which is further away from the shuttle. Since it takes 7.5 s for the astronaut to make contact with the shuttle, the distance would be
d = vt = 1.83 * 7.5 = 13.7 m
