g solid wooden sphere of volume 0.0100 m3 floats freely exactly one-half submerged in a liquid of density 800 kg/m3. a lightweight cord is now tied to the sphere and is used to pull the sphere under the surface and hold it completely submerged. what is the tension in the cord?

Answers

Answer 1

The cord has a one percent tension. When something or someone pulls on a cord or string, the tension that results is what is being described.

We are aware that T = mg + ma is the formula used to compute the force of tension.

Calculation:

T = mg + ma

T = 800 × 9.8 + 800 ×9.8

How much tension is there?

Tension is the force that is sent through a rope, string, or wire when two opposing forces pull on it. Along the whole length of the wire, the tension force pulls energy equally on the bodies at the ends. Every physical object that comes into contact with another one exerts force on it.

The acceleration due to gravity on the Moon's surface is known to be about one-sixth of the acceleration due to gravity on the Earth.
A rock falls under a gravitational force of 16.3 N on the moon.
Please help me figure out the mass of the rock.

Answers

Answer:

The mass of the rock is approximately 9.97 kg

Explanation:

From the question, we have;

The acceleration due to gravity on the Moon = (1/6) × The acceleration due to gravity on the Earth

The gravitational force under which a rock falls on the Moon = 16.3 N

The acceleration due to gravity on Earth, g ≈ 9.81 m/s²

Therefore, the acceleration due to gravity on the Moon, a = (1/6) × 9.81 m/s² ≈ 1.635 m/s²

The relationship between the force with which the rock falls and the acceleration of the motion resulting in the force is given by the following relationship;

F = m × a

Where;

F = The force = 16.3 N

m = The mass of the object acted on by the force = The mass of the rock

a = The acceleration of the motion of the object = 1.635 m/s²

From F = m × a, we have;

m = F/a

∴ m = 16.3 N/(1.635 m/s²) = 9.96941896 kg

The mass of the rock, m ≈ 9.97 kg.

How much force does it take to accelerate a 3.50 kg mass from 3.00 m/s to 17.0 m/s in a time of 2.00 seconds?

Answers

Answer:

Force = 24.5 Newton

Explanation:

Given the following data;

Mass = 3.50 kg

Initial velocity, u = 3 m/s

Final velocity, v = 17 m/s

Time, t = 2 seconds

To find the force;

First of all, we would determine the acceleration of the object using the formula;

Acceleration = (v - u)/t

Acceleration = (17 - 3)/2

Acceleration = 14/2

Acceleration = 7 m/s²

Now, we can find the force using the formula;

Force = mass * acceleration

Force = 3.5 * 7

Force = 24.5 Newton

Calculate the refractive index for a substance where the angle of incidence is 300 , the angle of refraction is 600 , and the refractive index of second substance is 1.5

Answers

Answer:

η₁ = 2.6

Explanation:

Here, we will use snell's law to calculate the refractive of the substance:

[tex]\frac{\eta_2}{\eta_1} = \frac{Sin\theta_1}{Sin\theta_2}[/tex]

where,

η₁ = refractive index of first substance = ?

η₂ = refractive index of second substance = 1.5

θ₁ = angle of incidence = 30°

θ₂ = angle of refraction = 60°

Therefore,

[tex]\frac{1.5}{\eta_1} = \frac{Sin\ 30^0}{Sin\ 60^0}[/tex]

η₁ = 2.6

Question:
Define work.

Answers

Answer:

Work, in physics, refers to the measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.

Hey there!

Work is defined as the the force which gets applied to an object in order to displace (move) it. For example, you work in order to walk up & down the stairs. For this, you need to apply force as well. So, work done = force × distance.

Explanation:

Given that,

The mass of a truck, m = 200 kg

Speed of the truck, v = 20 m/s

We need to find the momentum of the truck. The formula for momentum is given by :

p = mv

so,

[tex]p=200\times 20\\\\p=4000\ kg-m/s[/tex]

So, the momentum of the truck is equal to 4000 kg-m/s.

Answers

Answer:

The water rises by 4.45 m

Explanation:

Mass is constant

Mass = Volume /Specific Volume

Mass = 200/(1*10^-3*1.001) = 199.8 Kg

Volume after heating = specific volume * mass

= 1.008 *10^-3 lt/gm * 199800 gm

= 201.398 t

Change in volume = 1.3986

(pi)r^2 *h = 1.3986 *10^-3 m^3

3.14 * (1*10^-2 m)^2 *h = 1.3986 *10^-3 m^3

H = 4.45 m

A 2.0 kg sphere with a velocity of 6.0 m/s collides head-on and elastically with a stationary 10 kg sphere

Answers

Question: A 2.0 kg sphere with a velocity of 6.0 m/s collides head-on and elastically with a stationary 10 kg sphere, What is thier velocities after collision.

Answer:

v = 6 m/s, v' = 0 m/s

Explanation:

From the question,

For Elastic collision,

mu+m'u' = mv+m'v'......................... Equation 1

Where m = mass of the first sphere, m' = mass of the second sphere, u = initial velocity of the first sphere, u' = initial velocity of the second sphere, v = final veolocity of the first sphere, v' = final velocity of the second sphere.

Also,

The relative velocity before collision = relative velocity after collision

u-u' = v-v'............................ Equation 2

Given:  m = 2 kg, m' = 10 kg, u = 6 m/s, u' = 0 m/s

Substitute into equation 1 and 2

2(6)+10(0) = 2v+10v'

2v+10v' = 12.............. Equation 3

6-0 = v-v'

v-v' = 6 ................... Equation 4

Solve equation 3 and 4 simultaneously.

v = 6+v'............. Equation 5

Substitute equation 5 into equation 3

2(6+v')+10v' = 12

12+2v'+10v' = 12

12v' = 12-12

v' = 0/12

v' = 0 m/s.

Also substitute the value of v' into equation 5

v = 6+0

v = 6 m/s
