Answer:
At most 3 sandwiches i would eat at this situation
Step-by-step explanation:
Making a first sandwich has a constant value 10$ but its marginal benefit is 12$. There is a 2$ benefit exist if i eat one.
Making the second one costs 20$ but its marginal benefit is 22$. Still 2$ benefit is exist if i eat the second one also.
Making the third one costs 30$ ant its marginal benefit also 30$. There is a even situation here. Making three sandwiches still an option.
After third one marginal benefit becomes lower than marginal cost of sandwiches.
Answer:
Step-by-step explanation:
Surface area of a cube of side-length 0.5m
= 6(0.5)^2 = 6(0.25) = 1.5 sq.m.
Answer:
Neither
Step-by-step explanation:
It has a y intercept, which is -6, which changes the whole graph, so its neither
Step-by-step explanation:
(i) Sum the forces at point M in the x direction.
∑F = ma
-T sin 30° − T sin 30° + 5 N = 0
2T sin 30° = 5 N
T = 5 N
(ii) Sum the forces on the ring in the x direction.
∑F = ma
T sin 30° − N = 0
N = 2.5 N
Sum the forces on the ring in the y direction.
∑F = ma
T cos 30° − mg − Nμ = 0
Nμ = T cos 30° − mg
2.5 μ = 5 cos 30° − 2
μ = 0.932
(iii) Sum the forces on the ring in the y direction.
∑F = ma
T cos 30° − m₁g − m₂g + Nμ = 0
m₂g = T cos 30° − m₁g + Nμ
m (10) = 5 cos 30° − 2 + (2.5)(0.932)
m = 0.466 kg
