Answers

To answer this question, you need to recognize that energy is conserved. The initial energy was kinectic and then transferred to internal; therefore, in this problem, (aka final energy) internal energy = kinectic energy (aka initial energy).

Kinectic energy = 0.5 * m * v^2

5836 = 0.5 * m * (13.4)^2
89.78m = 5836
Mass = 65 kgs

.A water tank has dimensions
of 6m x 4m x 4m. Find the pressure exerted by
water at the base of dam when it is half
filled. ( Density of water - 1000 kg/ m2,
acceleration
due to to gravity is 9.8m/s2

Answers

Answer:

9800Nm⁻²

Explanation:

Given parameters:

Dimensions of the water tank = 6m x 4m x 4m

Density of water  = 1000kgm⁻³

Gravity  = 9.8m/s²  

Unknown:

Pressure exerted by the water at the base of the dam  = ?

Solution:

The pressure exerted by the water is given as:

  Pressure  = density of water x acceleration due to gravity x height of water

The height of the water here is half = 1m

   

Pressure  = 1000 x 9.8 x 1 = 9800Nm⁻²

Which of the following is NOT a criteria for a celestial object to be a planet?

-The object has cleared the neighborhood around its orbit of smaller objects.

-The object is in orbit around the Sun.

-The object has a nearly spherical shape.

-The object must be massive enough have a gravitational pull on the sun.

Answers

Answer:

The option which is not a criteria for a celestial object to be a planet is;

The object must be massive enough have a gravitational pull on the Sun

Explanation:

There are three criteria for a celestial object to be classified as a planet including;

1) The object's orbit is around the Sun

2) The shape of the object is nearly round due to its mass which is capable of assuming hydrostatic equilibrium

3) Other smaller objects in the neighborhood around the object has been cleared by the object

Therefore, the option which is not a criteria for a celestial object to be a planet is that it must be massive enough to have a gravitational pull on the Sun as every two objects in the Universe share a common gravitational pull according to Newton's Law of Gravitation.

A 2-kg ball traveling eastward at 5 m/s hits a 5-kg ball moving at 1 m/s eastward. The 2-kg ball bounces west at 3.0 m/s. What is the speed of the 5kg ball?

Answers

Answer:

1.8 m/s

Explanation:

Step one:

given data

m1= 2kg

u1= 5m/s

m2= 5kg

u2= 1m/s

v1= 3m/s

From

m1u1+m2u2= m1v1+m2v2

substitute

2*5+5*1 = 2*3+5*v2

10+5= 6+5v2

15-6= 5v2

9= 5v2

divide both side by 5

v2= 9/5

v2= 1.8 m/s

A box weighs 1300 N. When a horizontal force of 390 N has applied the box accelerates at 1.3 m/s2. What is the magnitude of the frictional force?

Answers

Answer:

Ffriction = 217.7[N]

Explanation:

First, we must find the mass of the box, we must remember that the weight is defined as the product of the mass by acceleration.

[tex]w=m*g[/tex]

where:

w = weight [N] (units of Newtons)

m = mass [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]1300=m*9.81\\m=132.51[kg][/tex]

Now we must use Newton's second law, which tells us that the sum of forces is equal to the product of mass by acceleration.

∑F = m*a

where:

∑F sum of forces

m = mass = 132.51[kg]

a = acceleration = 1.3[m/s²]

We must know that the forces that act are the horizontal force that moves the box and the friction force in the negative direction that acts against the movement.

Now replacing:

[tex]390-f_{friction}=132.51*1.3\\390-172.26=f_{friction}\\f_{friction}=217.7[N][/tex]

Can anyone prove ADIABATIC PROCESS ???​

Answers

Answer:

The adiabatic process can be derived from the first law of thermodynamics relating to the change in internal energy dU to the work dW done by the system and the heat dQ added to it. The word done dW for the change in volume V by dV is given as PdV. Hence, the equation is true for an adiabatic process in an ideal gas.

a physical quantity is defined as mass per uint volume .what is its si unit.


A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as the combination of a numerical value and a unit. For example, the physical quantity mass can be quantified as n kg, where n is the numerical value and kg is the unit. A physical quantity possesses at least two characteristics in common, one is numerical magnitude and other is the unit in which it is measured.

An equilateral triangle is a triangle with all three sides of equal length. All of the angles in an equilateral triangle are equal.

Answer:

60

Explanation:

it's equilateral...all angles are equal...180÷3=60ffs

Each angle of triangle is 60 degree.

What is equilateral triangle ?

If a Triangle having all the three sides of equal length and corresponding angle also to be equal than this triangle is known as equilateral triangle.

By definition of equilateral triangle it is known that all the sides of a triangle are equal and by the angle sum property tells us that a triangle's angles add up to 180. It also tells us that every side of a triangle is the same, and every angle of an equilateral triangle is the same.

Let each angle of triangle be x :

[tex]\begin{aligned} x+x+x&= 180^{o}\\3x&=180^{0}\\x&=60^{o}\end{aligned}[/tex]

Find the work done by a man who is pulling a box of 45kg of mass by means of rope which makes angle of 45 degrees.

Answers

Answer:

0

Explanation:

Since no distance is given, the force is not doing any work

No work is done by the man since we do not know the distance or displacement.

Work is only said to be done when the force applied on an object moves it through a particular distance.

 Work done  = Force x distance.

Since no distance is given in this problem, we can as well assume that the force applied is doing no work on the object.

6th grade science!!!!!!!!!!​

Answers

Answer:

D. All of the above

Explanation:

Global warming may cause all of the given choices.

Global warming is the rise in surface temperature. This is due to the trapping of heat within the earth surface.

It is as a result of huge amount of greenhouse gases within our atmosphere. They typically permit short wave radiations to escape and they do not allow short wave radiation to pass through. This in turn produces heat.

The heat can melt polar ices and glaciers. This in turn will cause sea levels to rise. Also, the ocean temperature will generally increase due to this.
