A cylindrical storage tank has a radius of 1.35 m. When filled to a height of 3.45 m, it holds 14,014 kg of a liquid industrial
Kruka [31]

Answer:

709.93 kg/m³

Explanation:

Density: This can be defined as the ratio of the mass of a body to the volume of that body. The S.I unit of density is kg/m³

From the question above,

D = m/v.............................. Equation 1

Where D = density, m = mass, v = volume.

Note: The volume of the liquid is equal to the volume of the height occupied by the liquid in the container

Since the tank is cylindrical,

v = πr²h........................ Equation 2

Where r = radius of the the tank, h = height of the liquid in the tank

Substitute equation 2 into equation 1

D = m/(πr²h)............... Equation 3

Given: m = 14014 kg, r = 1.35 m, h = 3.45 m, π = 3.14

Substitute into equation 3

D = 14014/(3.14×1.35²×3.45)

D = 14014/19.74

D = 709.93 kg/m³

A circuit with a 60 V battery, a 7 Ω resistor, a resistor with 0.2 A across it, and another 7 Ω resistor in series. What is the
skelet666 [1.2K]

Answer:

28.6 ohm

Explanation:

there is a 3rd resistor in series. voltage drop across the resistors will be equal to 60v

7*.2+7*.2 +.2x = 60

2.8+.2x = 60

.2x = 57.2

x = 28.6

Rock X is released from rest at the top of a cliff that is on Earth. A short time later, Rock Y is released from rest from the s
MArishka [77]

Answer:

<h2>D) S increases because at all times Rock X falls with a greater speed than Rock Y</h2>

Explanation:

As we know that Stone X is dropped first and then after some time stone Y is dropped

Now we have

v_x = gt_1

similarly for Y

v_y = g(t_1 - \Delta t)

now the relative acceleration of two stones while they are in air is ZERO

also we know from above equations

v_x > v_y

so the separation between two stones will keep on increasing as the speed of X is more than the speed of Y
