Answer:
Well concluding there is no gravity their motions would be slow and lightweighted. Let's say they were playing on Earth it would approximately take around 5 to 6 minutes even less, so in space it will approximately take around 10 to 12 minutes may be more but this is just my opinion after using my calculator! Hope this helped!
Answer:
a)
b)
c)
d)
Explanation:
Given:
- mass of the astronaut,
- vertical displacement of the astronaut,
- acceleration of the astronaut while the lift,
a)
<u>Now the force of lift by the helicopter:</u>
Here the lift force is the resultant of the force of gravity being overcome by the force of helicopter.
where:
- force by the helicopter
- force of gravity
b)
The gravitational force on the astronaut:
d)
Since the astronaut has been picked from an ocean we assume her initial velocity to be zero,
using equation of motion:
c)
Hence the kinetic energy:
Answer:
Explanation:
Given
acceleration = 2m/s²
time = 4secs
initial velocity u = 0m/s (motor starts from rest)
Using the equation of motion v = u+at
v = 0+2(4)
v =0+8
v = 8m/s
Hence the final velocity of the car s 8m/s.
Average velocity = distance / time
S = ut + 1/2at²
S = 0+1/2(2)4²
S = 16m
If the distance covered is 16m
Average velocity = 16/4
Average velocity = 4m/s
The answer is E. The objects loses all its charge
Answer:
Kinetic
Explanation:
Potienal is building up power where kinetic means moving
