Answer:
a = 1.764m/s^2
Explanation:
By Newton's second law, the net force is F = ma.
The equation for friction is F(k) = F(n) * μ.
In this case, the normal force is simply F(n) = mg due to no other external forces being specified
F(n) = mg = 15kg * 9.8 m/s^2 = 147N.
F(k) = F(n) * μ = 147N * 0.18 = 26.46N.
Assuming the object is on a horizontal surface, the force due to gravity and the normal force will cancel each other out, leaving our net force as only the frictional one.
Thus, F(net) = F(k) = ma
26.46N = 15kg * a
a = 1.764m/s^2
Answer:
I think it's B
Explanation:
Because hese receptors are found in muscles, tendons, and joints.
5Newtons or 5N
Ten newtons minus five Newton’s is 5 Newton’s
Answer:
Mass=3,height=50 and time=15,g=10,P=?
P=mgh/t....which is 3×10×50=1500/15=100Watts
Answer:Combustion
Explanation:The chemical reaction is called combustion and requires oxygen. Combustion changes the potential chemical energy into kinetic energy in form of heat.
