Encuentra la magnitud y dirección de la suma de los siguientes vectores: A= 7m al noreste B= 12m 50° al oeste del norte

Answer:

1. geothermal

2. nuclear

3. biofuel

Answer:

-2 m/s

Explanation:

The computation of the acceleration of the block is as follows:

The volume of the block is

V = 1kg ÷ 1,000 kg/m^3 = 1 ÷ 1,000 m^3

Now at the time of submerging in the oil

Net force is

[tex]m_g - F_B = m \times (-a)\\\\m_g - v\times S_{oil} \times g = -ma\\\\a = (\frac{v}{m} \times S_{oil} - 1) g\\\\= (\frac{1}{1000} \times 0.8 \times 1000 -1 ) \times 10\\\\[/tex]

= -2 m/s

Answer:

Work, in physics, 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

Explanation:

Answer:

Weight (Force) = mass x acceleration due to gravity Weight = 90.0 kg x 9.80 m/s2 Weight = 882 N or 882 kg m/s2 Page 2 Newton's Notes 2 Gravity has an effect on an object in the vertical direction only.

Answer:

882.9N

Explanation:

1kg is 9.81n

To start the magnetic field

Because copper is the second-best electrical conductor, it's cheaper and more plentiful than silver, and it's relatively easy to get it out of the ground, refine it, and form it into wires.

(If the electrical wiring in your house was all silver wire, I guess nothing would ever work, because people would keep stealing your wiring.)

Answer:

r = 0.849 m

Explanation:

Given that,

The masses of two objects, [tex]m_1=m_2=2\times 10^2\ kg[/tex]

The force between the objects, [tex]F=3.7\times 10^{-6}\ N[/tex]

We need to find the distance between the masses. The force between two objects is given by the relation as follows :

[tex]F=G\dfrac{m_1m_2}{r^2}[/tex]

r is the distance between them

[tex]r=\sqrt{\dfrac{Gm_1m_2}{F}} \\\\r=\sqrt{\dfrac{6.67\times 10^{-11}\times (2\times 10^2)^2}{3.7\times 10^{-6}}} \\\\r=0.849\ m[/tex]

So, the distance between them is 0.849 m.

D. Solution

Explanation:

Sugar dissolved in water is an example of solution.

A solution is a homogenous mixture of solutes and solvents.

In a solution the solute particles ae distributed uniformly in the solvents. The solute is the substance and it is the sugar here that is dissolved to make a solution.

The solvent is the water in this instance that helps to dissolve the solute.

Answer:

D. Solution

Explanation:

Dissolving sugar in water is an example of a physical change. Here's why:

A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result.

Answer:

Explanation:

Example

Answer:

5 kg

Explanation:

Acceleration = 8 m/s^2

Force = 40 N

Force = mass * acceleration

mass = force / acceleration

mass = 40 / 8

mass = 5 kg

Answer:

During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space.

Answer:

b.They include familiar metals such as gold, silver, copper, and nickel.

They include familiar metals such as gold, silver, copper, and nickel.

Transition metals are like main group metals in many ways: They look like metals, they are malleable and ductile, they conduct heat and electricity, and they form positive ions.

"A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile."

"Transition metals are placed between s−block and p−block elements in periodic table. They are termed as d-block elements. These metals are unstable and exhibit transitional behavior between s block and p block elements, hence the name transition metals."

"Electricity is defined as the rate of flow of charges in a conductor."

Electricity is defined as the effects of an electric charge. An example of electricity is the force that powers a light bulb. An example of electricity is lightning. An example of electricity is static electricity, the buildup of electric charges on an object's surface.

Answer:

1) Energy transfer is the movement of energy from one location to another. ... Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.

2)A swinging pirate ship ride at a theme park. Kinetic energy is transferred into gravitational potential energy.

A boat being accelerated by the force of the engine. ...

Bringing water to the boil in an electric kettle.

3)Common examples of energy storage are the rechargeable battery, which stores chemical energy readily convertible to electricity to operate a mobile phone, the hydroelectric dam, which stores energy in a reservoir as gravitational potential energy, and ice storage tanks, which store ice frozen by cheaper energy at night

Explanation:

Force = Mass*Acceleration

Remember this formula because its one of the most used formula in all of physics.

250N = 80kg*Acceleration

There would definitely be friction because of the water, but since this says high school physics, you prolly can assume it to be negligible

Answer:

30m/s

Explanation:

Given parameters:

Distance  = 12m

Time taken  = 0.4s

Unknown:

Velocity of the tennis ball = ?

Solution:

Velocity of a body is the displacement per unit of time.

  Velocity  = [tex]\frac{displacement}{time}[/tex]  

So;

      Velocity  = [tex]\frac{12}{0.4}[/tex]   = 30m/s
