Answer:
Net force is 86.135 N , N 82.255° W
Explanation:
Resolving all forces vertically and horizontally.
First vertically.
20N = 20sin90 = 20
30N = 30sin(90-30)= 30sin60
=25.981
25N = 25sin0 = 0
35N =- 35sin80= -34.368
Total of vertical =
20+25.981+0-34.368
= 11.613N
For horizontal
20N =- 20cos 90 = 0
30N =- 30cos 30 = -25.981
25N = -25cos0 = -25
35N = -35cos 10 = -34.468
Total horizontal = 0-25.981-25-34.368= -85.349
Resultant force = √(11.613)²+(-85.349)²
= √(134.862) +(7284.452)
= √ 7419.314
= 86.135 N
Tan(tita°) = 11.613/-85.349
Tan(tita°) =- 0.136
tita° = Tan^-1(-0.136)
tita° = -7.745
North of West = 90-7.745
= 82.255°

Answer:
2.5 kg/m³
Explanation:
Absolute pressure = gauge pressure + atmospheric pressure
P = Pg + Pa
The gauge pressure caused by the weight of a fluid is called the static pressure. It is equal to the density of the fluid × acceleration due to gravity × depth of the fluid,
Pg = ρgh
Therefore:
P = ρgh + Pa
300 Pa = ρ (10 m/s²) (8.00 m) + 100 Pa
ρ = 2.5 kg/m³

Answer:
The cuboid and the cube exert the same pressure on the floor.
Explanation:
To answer this question, we must first consider that the area of the cuboid is equal to 24cm^2, while the area of the cube is equal to 16cm^2.
With that, we must calculate the pressure that each exerts, with the formula:
P = F / A
Cuboid: P = 60 / 0.0024 = 25000 N/m^2
Cube: P = 40 / 0.0016 = 25000 N/m^2
