Mechanical digestion is chewing, and chemical digestion is the saliva in your mouth breaking down food.
Answer:
2.8 N
Explanation:
Fp = 7.7 N
mA = 12.1 kg
mB = 7 kg
Let a be the acceleration and Fc be the contact force between A and B.
By the free body diagram, use Newton's second law
Fp - Fc = mA x a ..... (1)
Fc = mB x a ..... (2)
Adding both the equations
Fp = (mA + mB) x a
7.7 = (12.1 + 7) x a
a = 0.4 m/s^2
Substitute this value in equation (2), we get
Fc = 7 x 0.4 = 2.8 N
Thus, the contact force between the two blocks is 2.8 N.
Explanation:
A. Increase Energy because simple machines are supposed to help humans use less energy and less force when doing a task that normally requires a lot of force and energy
Answer:
μ = 0.724
Explanation:
maximum acceleration for SHM
a = ω²A
ω = 2πf
a = 4π²f²A
a = 4π²(1.50)²(0.080) = 7.106... m/s²
μ = F/N = ma/mg = a/g = 7.106/9.81 = 0.7243...
I'm cynical that a block can be cynical. Wassa madder, doesn't trust anyone?
Another reason why cats hate water is attributed to their history. There is not much in a cat's background to recommend them for successful interactions with bodies of water, be it small or big. Cat's ancestors lived in dry arid places which means rivers or oceans weren't obstacles they had to face.
Hope this helps:)
