Answer:
<h3>0.69</h3>
Explanation:
Using the Newtons law of motion;
Fm is the moving force = 400N
Ff is the frictional force = μR
μ is the coefficient of kinetic friction
R is the reaction = mg
m is the mass
a is the acceleration
The equation becomes;
Hence the coefficient of kinetic friction between the box and floor is 0.69
Mass, weight. Mass is independent of the object’s location, whereas weight is not.
You can use the impulse momentum theorem and just subtract the two momenta.
P1 - P2 = (16-1.2)(11.5e4)=1702000Ns
If you first worked out the force and integrated it over time the result is the same
Answer: Foods that naturally are nutrient-rich include fruits and vegetables. Lean meats, fish, whole grains, dairy, legumes, nuts, and seeds also are high in nutrients.
Answer: The perpendicular force to be used to tighten the bolt is
F=347.8N
Explanation:
Mathematically the torque is expressed as
T=F*L
Where T= torque in Nm
F= force in N
And L = perpendicular distance
Now given
T=63.3Nm
L=18.2cm to meter 18.2/100
0.182m
F=?
Making F the subject of the formula in our equation
F=T/L
F=63.3/0.182
F=347.8N
What is torque?
Torque is the product of force and perpendicular distance of the line of action.
