Hello!
I'm just going to ignore the name of the building and just do the math
1 foot is equivalent to 0.3048 meters
if the building is 1368 feet tall, multiply it by 0.3048 to get 416.9664 meters
I hope this helps, and have a nice day!
5.
explanation: the answer is 5
<span>The normal force acting on the vehicle is 4440 N. Normal force is the force perpendicular to the ground. The important given values are the mass of the space vehicle (1200 kg) and the gravitational field strength (3.7 N/kg). To get a value of Force in Newtons, we just multiply the two numbers together: force = field strength * mass = 3.7 N/kg * 1200 kg = 4440 N.</span>
Torque = (force perpendicular to the radius) x (length of the radius)
Torque = (25 N) x (5 m)
<em>Torque = 125 N-m</em>
<span>λ=h/(mv)
0.945*10^-10 = 6.626*10^-34/mv
mv = 6.626*10^-34/0.945*10^-10
v = 6.626*10^-34/(0,945*10^-10*1.6749*10^-27...
v = 6.626*10^-34/1.5828*10^-37
v = 4.186*10^3 m/s</span>
