Answer:
Explanation:
Since the system is in international space station
so here we can say that net force on the system is zero here
so Force by the astronaut on the space station = Force due to space station on boy
so here we know that
mass of boy = 70 kg
acceleration of boy = 
now we know that
now for the space station will be same as above force
Answer:
Excessive paranoia, worry, or anxiety.
Long-lasting sadness or irritability.
Extreme changes in moods.
Social withdrawal.
Dramatic changes in eating or sleeping patter

hope it helps brainliest if right thx :)
The power of the engine is 320 W.
<u>Explanation:</u>
Power may be defined as the rate of doing work (or) work done per unit time. One unit of energy is used to do the one unit of work.
Power = Work done / Time taken
Given, Force = 80 N, height = 5 m , final velocity = 4 m/s
To calculate the power, we must know the time taken.
To find the time, use the distance and speed formula which is given by
Time = Distance / speed
Here distance = 5 m and speed = 4 m/s
Time = 5 / 4 = 1.25 s.
Now, Power = work done / time
= (F * d) / t = (80 * 5) / 1.25
Power = 320 W.
The standard unit of power is watt (W) which is joule per second.
You take the inverse of the total resistances of each branch and add them up.
So if you have 5ohm, 7 ohm, and 10ohm, you would add
1/5 + 1/7 + 1/10 = 31/70
Then flip it back by either using the <span>x<span>−1</span></span><span> (inverse) key on your calculator or simply dividing 70 by 31 to get a total of 2.26ohms</span>
Answer:
The distance by the ball clear the crossbar is 1.15 m
Explanation:
Given that,
Distance = 44 m
Speed = 24 m/s
Angle = 31°
Height = 3.05 m
We need to calculate the horizontal velocity
Using formula of horizontal velocity
Put the value into the formula
We need to calculate the vertical velocity
Using formula of vertical velocity
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
We need to calculate the vertical height
Using equation of motion
Put the value into the formula
We need to calculate the distance by the ball clear the crossbar
Using formula for vertical distance
Put the value of h
Hence, The distance by the ball clear the crossbar is 1.15 m
