The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
Answer:
effeciency n = = 49%
Explanation:
given data:
mass of aircraft 3250 kg
power P = 1500 hp = 1118549.81 watt
time = 12.5 min
h = 10 km = 10,000 m
v =85 km/h = 236.11 m/s
kinetic energy
kinetic energy 
gravitational energy 
total energy 
effeciency n = = 49%
As an object falls from rest, its gravitational energy is converted to kinetic energy
G.P.E = K.E = mgh
K.E = (80 Kg)(9.8 m/s²)(30 m)
K.E. = 23,520 J
<span>C) Humans and their activities do not affect the natural cycles of the Earth
you can think that </span>Humans and their activities do not affect the natural cycles of the Earth.
Answer:
p=1
Explanation:
Well me know that v=m/s
and that a=m/s^2
so
Note: We don't take into account 2 because it's a scalar, it doesn't have units so it doesn't add anything to the equation.
