Answer:

The depth to which the hydrometer sinks is approximately 24.07 cm

Explanation:

The given parameters are;

The diameter of the hydrometer tube, d = 2.3 cm

The mass of the content of the tube, m = 80 g

The density of the liquid in which the tube floats, ρ = 800 kg/m³

By Archimedes' principle, the up thrust (buoyancy) force acting on the hydrometer = The weight of the displaced liquid

When the hydrometer floats, the up-thrust is equal to the weight of the hydrometer which by Archimedes' principle, is equal to the weight of the volume of the liquid displaced by the hydrometer

Therefore;

The weight of the liquid displaced = The weight of the hydrometer, W = m·g

Where;

g = The acceleration due to gravity ≈ 9.81 m/s²

∴ W = 80 g × g

The volume of the liquid that has a mass of 80 g (0.08 kg), V = m/ρ

V = 0.08 kg/(800 kg/m³) = 0.0001 m³ = 0.0001 m³ × 1 × 10⁶ cm³/m³ = 100 cm³

The volume of the liquid displaced = 100 cm³ = The volume of the hydrometer submerged, [tex]V_h[/tex]

[tex]V_h[/tex] = A × h

Where;

A = The cross-sectional area of the tube = π·d²/4

h = The depth to which the hydrometer sinks

h = [tex]V_h[/tex]/A

∴ h = 100 cm³/( π × 2.3²/4 cm²) ≈ 24.07 cm

The depth to which the tube sinks, h ≈ 24.07 cm.

Explanation:

Answer:

At 400 m the potential energy of the mountain climber doubled the initial value.

Explanation:

Given;

initial height of the mountain climber = 200 m

final height of the mountain climber, = 400 m

The potential energy of the mountain climber is calculated as;

Potential energy, P.E = mgh

At 200 m, P.E₁ = mg x 200 = 200mg

At 400 m, P.E₂ = mg x 400 = 400mg

Then, at 400 m, P.E₂ = 2 x 200mg = 2 x P.E₁

Therefore, at 400 m the potential energy of the mountain climber doubled the initial value.

Answer:

Explanation:

Initial velocity is 0. In the equation v = v0+at where v0 is the initial velocity of 0, we only have to fill in -9.8 for a and 2 for t to get the velocity after 2 seconds -19.6 m/s; after 5 seconds, when it hits the ground, a = -9.8 and t = 5 to give a velocity of -49 m/s.

Answer:

98.13m

Explanation:

Complete question

Daniel is 50.0 meters away from a building. Tip of the building makes an angle of 63.0° with the horizontal. What is the height of the building

CHECK THE ATTACHMENT

From the figure, using trigonometry

Tan(θ ) = opposite/adjacent

Where Angle (θ )= 63°

Opposite= X = height of the building

Adjacent= 50 m

Then substitute the values we have

Tan(63)= X/50

1.9626= X/50

X= 1.9626 × 50

X= 98.13m

Hence, the height of the building is 98.13m

Answer:

A. If motion starts and stop at the same location, then the displacement is zero

C. Distance is always greater than or equal to the magnitude of the displacement

Explanation:

The displacement of a body is a vector quantity that gives the shortest (straight line) distance moved by an object in motion, from its initial position to its final position. The displacement can also be described as the final position relative to the initial position of an object, such that the displacement vector, 's', is given as follows;

[tex]s = x_f - x _i[/tex]

The displacement gives the direct length between two points, with regards to the direction of motion between the points. It can only be described by both the magnitude and the direction

Therefore, displacement can be positive (forward motion), negative (backward motion), or zero (where there is motion that stops at the starting point)

Therefore, a correct options is; If motion starts and stop at the same location, then the displacement is zero

Displacement, being a vector quantity will have both magnitude and direction

Distance, however, is a scalar quantity, it specifies only magnitude, but does not specify direction

Distance, describes the length of the path taken from one point to the other. Distance gives the total movement a body makes, without regards to the direction of the motion

Therefore, distance is always positive or zero (here only the object is stationary)

Therefore, a correct option is; Distance is always greater than or equal to the magnitude of the displacement

Therefore, the correct options are;

If motion starts and stop at the same location, then the displacement is zero

Answer:

8892 ml = 8892 gm = 8892000 mg

1 ml = 1 gram

8892 ml = 8892 gram

1 gram or ml = 1000 milligram

8892 ml = 8892 × 1000 = 8892000 milligram

have a good day :)

Explanation:

remember: 1 kilogram = 1000 gram = 1000000 milligram.

Milliliter is expressed same as gram and liter is expressed same as kilogram.

1 meter = 100 cm, 1 kilometer = 1000 meter,

1 cm = 10 millimeter.

You can't convert ml to gm unless you know the substance. They're all different.

E) 147 V

Explanation:

Ra+Rb+Rc = 14.0

V = IR

V = (10.5)(14.0)

V = 147 V

The potential difference across the source will be c)12V

Ohm's law states that  the current through a conductor between two points is directly proportional to the voltage across the two points .

since , R(A) , R(B) AND R(C) are in parallel combination , hence  equivalent

resistance of the circuit will be

1/R = 1/R(A) + 1/ R(B) + 1/ R(C)

1/R= 1/2 + 1/4 +1/8

1/R = 7/8

R = 8/7 ohm

from ohm's law

Voltage = current * resistance

V( source ) = current (in circuit ) * R (equivalent resistance)

V = 10.5 * (8/7)

V = 12 V

The potential difference across the source will be c) 12V

Answer:

The answer is below

Explanation:

A diver works in the sea on a day when the atmospheric pressure is 101 kPa. The diver uses compressed air to breathe under water. 1700 litres of air from the atmosphere is compressed into a 12-litre gas cylinder. The compressed air quickly cools to its original temperature. Calculate the pressure of the air in the cylinder.

Solution:

Boyles law states that the volume of a given gas is inversely proportional to the pressure exerted by the gas, provided that the temperature is constant.

That is:

P ∝ 1/V;   PV = constant

P₁V₁ = P₂V₂

Given that P₁ = initial pressure = 101 kPa, V₁ = initial volume = 1700 L, P₂ = cylinder pressure, V₂ = cylinder volume = 12 L. Hence:

P₁V₁ = P₂V₂

100 kPa * 1700 L = P₂ * 12 L

P₂ = (100 kPa * 1700 L) / 12 L

P₂ = 14308 kPa
