A solid wooden cube, 30cm on each side can be totally submerged in water if it is pushed downward with a force of 54N. What is t

Stels [109]

Answer:

the density of the wooden cube is 204.1 kg/m³

Explanation:

Given;

applied force, F = 54 N

length of each side of the solid wooden cube, L = 30 cm = 0.3 m

mass of the wooden cube is calculated as;

F = mg

m = F/g

m = 54/9.8

m = 5.51 kg

The volume of the wooden cube is calculated as;

V = L³

V = (0.3)³

V = 0.027 m³

The density of the wooden cube is calculated as;

ρ = m/V

ρ = (5.51 kg) / (0.027 m³)

ρ = 204.1 kg/m³

Therefore, the density of the wooden cube is 204.1 kg/m³

Two students are sitting 1.50 m apart. One student has a mass of 70.0 kg and the other has a mass of 52.0 kg. What is the gravit

algol [13]

Answer:

The gravitational force between them is $1.079\times10^{-7}\ N$ .

Explanation:

Given that,

Distance = 1.50 m

Mass of one student = 70.0 kg

Mass of other student = 52.0 kg

We need to calculate the gravitational force

Using formula of gravitational force

$F=\dfrac{Gm_{1}m_{2}}{r^2}$

Where, m₁ = mass of one student

m₂ = mass of other studen

r = distance between them

Put the value into the formula

$F=\dfrac{6.67\times10^{-11}\times70.0\times52.0}{1.50^2}$

$F=1.079\times10^{-7}\ N$

Hence, The gravitational force between them is $1.079\times10^{-7}\ N$ .
