Answer:yes
Explanation:
Work is done on an object when an applied force causes the object to move in the same direction as the force
Answer:
d₂ = 1.466 m
Explanation:
In this case we must use the rotational equilibrium equations
Στ = 0
τ = F r
we must set a reference system, we use with origin at the easel B and an axis parallel to the plank
, we will use that the counterclockwise ratio is positive
+ W d₁ - w_cat d₂ = 0
d₂ = W / w d₁
d₂ = M /m d₁
d₂ = 5.00 /2.9 0.850
d₂ = 1.466 m
Answer:
71 % of the earth's surface is covered in water
1 newton / square metre =0.0001 newton / square centimetre
Formula = divide the pressure value by 10000
