Answer:
Gravity
Explanation:
Pretty self-explanatory
We are kept on earth because of gravity and it keeps planets orbiting around the sun.
Answer:
50N
Explanation:
A1 (area of the smaller piston) = 20cm² = 0.2m²
F1 (force acting on the smaller piston) = 10N
F2 (force acting on the larger piston) =?
A2 (area of the larger piston) = 100cm² = 1m²
F1 / A1 = F2 / A2
F2 = (F1*A2) / A1
F2 = (10*1) / 0.2
F2 = 50N

Is it a sin to like them all...? haha
Answer:
90m/s
Explanation:
acceleration depicts the rate of change in velocity per time, therefore an acceleration of 3m/s² means the object increases its velocity 3m/s every second therefore the second squared in the denominator
acceleration = (3m/s)/1s =3m/s²
Therefore, if the plane starts from rest (initial speed = 0m/s) and it increases 3m/s every second for 30 seconds you would have:
final_speed = initial_speed + 3m/s²*30s =0+3*30 m*s/s² = 90 m/s
