A 7.8-kg solid sphere, made of metal whose density is 2500 kg/m3, is suspended by a cord. When the sphere is immersed in water (of density 1000 kg/m3), what is the tension in the cord

Answers

Answer 1

Answer:

Density of the liquid = 1470.43 kg/m³

Explanation:

Given:

Mass of solid sphere(m) = 6.1 kg

Density of the metal = 2600 kg/m³

Thus volume of the liquid :

Volume of the sphere = 6.1 kg/2600 kg/m³ = 0.002346 m³

The volume of water displaced is equal to the volume of sphere (Archimedes' principle)

Volume displaced = 0.002346 m³

Buoyant force =

Where

is the density of the fluid

g is the acceleration due to gravity

V is the volume displaced

The free body diagram of the sphere is shown in image.

According to image:

Acceleration due to gravity = 9.81 ms⁻²

Tension force = 26 N

Applying in the equation to find the density of the liquid as:

Thus, the density of the liquid = 1470.43 kg/m³

Answer 2

Density of the liquid = 1470.43 kg/m³

Given:

Mass of solid sphere(m) = 6.1 kg

Density of the metal = 2600 kg/m³

Thus volume of the liquid :

Volume of the sphere = 6.1 kg/2600 kg/m³ = 0.002346 m³

Volume displaced = 0.002346 m³

Acceleration due to gravity = 9.81 ms⁻²

Tension force = 26 N

How do you find the string tension?

The tension of a given rope can be thought of as T = (m × g) + (m × a). Where "g" is the gravitational acceleration of all objects supported by the rope and "a" is the other acceleration. All objects are carried by rope.

Tension represents the force a string or chord receives when someone or something pulls it. In other words, whenever the cord is pulled, it is said to be under tension. Whenever we deal with code or code issues, we assume that the code is flexible and has no mass.

A rock with a mass of 10. 0kg falls 25. 0m to

the ground. What is the work done by the

gravitational force if the weight of the ball

is 98. 0N?

Answers

Answer:

Explanation:Potential Energy is the stored energy of an object given its position relative to a body. Gravitational potential energy is one type of potential energy and is equal to the product of the object's mass (m), the acceleration caused by gravity (g), and the object's height (h) as distance from the surface of the ground (the body).

mass m of 3 kilograms falling at gravity g of 9.81 meter per second squared from a height h of 5 meters. Solve for potential energy Pe with the equation PE equals m times g times h

In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth's gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.

9.81 meters per second squared (or more accurately 9.80665 m/s2) is widely accepted among scientists as a working average value for Earth's gravitational pull. This figure is based on a measure of gravity at sea level at a latitude of 45°.

At higher altitudes, gravity decreases slightly.

The effect of latitude on gravitational force is relevant as gravity increases with increasing distance from the Equator. At the Equator, the Earth's gravity is 9.780 m/s2 and at the poles it is 9.832 m/s2 (source: CRC Handbook of Chemistry and Physics).

Gravitational acceleration (to three significant figures) for other planets and bodies in the solar system is as follows:

 m/s2 gn*

Sun 274 27.9

Mercury 3.70 0.38

Venus 8.87 0.90

Earth 9.81 1.00

According to ohm’s law, which combination of units is the same as the unit for resistance? volt ÷ ampere ampere × volt volt ampere ampere ÷ volt

Answers

Answer:

Volt divided by ampere

Explanation:

V = IR

V/I = R

The unit of resistance from ohms law is volt / ampere. Thus, option A is correct.

What is Ohm's law?

Ohm's law states that the applied voltage is directly proportional to the current flow in the conductor. It is written as V ∝ I. It remains constant at room temperature.

V is defined as  potential difference or voltage. The SI unit of voltage is volt(V). I is defined as the current flowing in the circuit. The SI unit of current is ampere (A).

Generally, ohm's law equals to V = IR. R represents resistance of a material which oppose the current flow in the conductor. The unit of resistance is ohm(Ω).

When the potential difference(V) is constant, Resistance is inversely proportional to current. Current increases with decrease of resistance and current decreases with increase of resistance.

To find  equivalent unit of resistance, the ohm's law is :

V = IR

R = V / I

  = volt / ampere.

Hence, the unit of resistance from ohm's law is volt / ampere. The SI unit of resistance is ohm(Ω). Thus, option A is correct.
