A 250-n force is directed horizontally as shown to push a 29-kg box up an inclined plane at a constant speed. Determine the magn
itude of the normal force
1 answer:
Answer:
246.38N
Explanation:
Check the complete question in the attached diagram
The normal force acting on the body on an inclined is equal to the weight of the object as shown;
Weight = Normal force = mgcosθ
m is the mass of the box = 29kg
g is the acceleration due to gravity = 9.81m/s²
θ is the angle of inclination = 30°
N = 29 * 9.81 * cos 30°
N = 284.49cos30°
N = 246.38N
<em></em>
<em>Hence the magnitude of the normal force is 246.38N</em>

Answer:
sweeps out equal areas in equal times.
Explanation:
As we know that there is no torque due to Sun on the planets revolving about the sun
so we will have
now we have
now we also know that
so rate of change in area is given as
so we will have
since angular momentum and mass is constant here so
all planets sweeps out equal areas in equal times.
