136g
Explanation:
Given parameters:
Density of mercury = 13.6g/cm³
Unknown:
Mass of :
1cm³ of mercury
10cm³ of mercury
Solution:
Density is the mass per unit volume of a substance. It is the amount of matter in a given volume.
Density =
Since the unknown in the problem is mass;
Mass = density x volume
Mass of 1cm³ of mercury = 13.6 x 1 = 13.6g
Mass of 10cm³ of mercury = 10 x 13.6 = 136g

Answer:
man upward acceleration is 0.14m/s^2
Explanation:
given data:
mass of man = 72 kg
downward force = 360 N
The mass of man of weight 72 kg is hang from two sections of rope, one section pf rope ties around man waist and other section is ties in man hands. when he pulls down the rope with 360 N force then each section of rope pulls with 360 N
we know that
Weight= mass × gravity= 72kg × 9.8 = 705.6N
Force = mass× acceleration
Force= -705.6 + (2 × 358) = 10.4 N
