SUPONIENDO QUE LA ACELERACIÓN DE LA GRAVEDAD ES [tex]9.80 m/s^{2}[/tex]

USANDO LA SEGUNDA LEY DE NEWTON:

m = 80.0 N/[tex]9.80 m/s^{2}[/tex] = 8.16 kg

Answer:

8kg

Explanation:

using the formula Force(F)=mass(m)×acceleration(a),

since we are finding the mass of the object,we will make m the subject by dividing both sides by a.

you will now get m= f/a

the acceleration on Earth is usually 10m/s

m= 80/10

m= 8/1 which is also 8kg

Answer: the answer is C

Explanation:

Answer:

D

Explanation:

Acceleration has both magnitude and direction. because velocity is vector quantity

average velocity is vector

linear momentum = mass× velocity

therefore it's also vector

force = mass× acceleration

acceleration is vector therefore force also vector

potential energy= mgh

energy in any form is scaler quantity therefore potential energy too is a scaler quantity.

Answer:

D. The Federal Reserve Bank can provide a short-term loan to banks

to prevent them from running out of money.

Explanation:

A bank run occurs when a large number of depositors withdraw their deposits simultaneously from a bank.

As the number of withdraws increases, the available cash in the bank decreases until a point that the bank can't give depositors their money.

In these situations, The Federal Reserve Bank acts as a lender of last resort that helps to reinforce the effect of deposit insurance, and to reassure bank customers that they will not lose their money.

Answer:

C

Explanation:

we know that light doesn't need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels.

Explanation:

Momentum = mass × velocity

p = mv

p = (120 kg) (30 m/s)

p = 3600 kg m/s

Given:

velocity, v = 30m/s

mass, m = 120kg

Therefore, momentum

p = mv

p = 120kg * 30m/s

p = 3600 kgm/s = [tex]3.6 * 10^3 kgms^{-1}[/tex]

A property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity broadly.

Momentum is a vector quantity, it has both magnitude and direction. Since momentum has a direction, it can be used to predict the resulting direction and speed of motion of objects after they collide.

Answer: find the answer in the explanation

Explanation: The potential energy in a circuit between two points is the workdone in taking units positive charge from one point to the other in the circuit. Its S.I unit is Joule.

Because voltage of a battery or cell in a circuit is the potential energy difference across its terminal

The potential energy difference between two points is one volt, if the workdone in taking one Coulomb of positive charge from one point to the other is one Joule.

Answer:

Captive animals are animals that are maintained by people in an enclosed place not allowing them to be free. There are several factors that make it difficult to reintroduce them to their natural habitats like:

-Captive animals don't learn the necessary skills to survive in their natural habitats like hunting skills.

-They are too used to have contact with people which makes them vulnerable to hunters.

-Sometimes these animals are not able to integrate with a wild population.

-It has been found that some captive animals are more susceptible to diseases.

Answer:

The fundamental wavelength of the vibrating string is 1.7 m.

Explanation:

We have,

Velocity of wave on a guitar string is 344 m/s

Length of the guitar string is 85 cm or 0.85 m

It is required to find the fundamental wavelength of the vibrating string. The fundamental frequency on the string is given by :

[tex]f=\dfrac{v}{2l}\\\\f=\dfrac{344}{2\times 0.85}\\\\f=202.35\ Hz[/tex]

Now fundamental wavelength is :

[tex]\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{344}{202.35}\\\\\lambda=1.7\ m[/tex]

So, the fundamental wavelength of the vibrating string is 1.7 m.

Answer:

General Howe and the British regrouped after losing the hill.

Explanation:

British forces marched to Breed's Hill on 17 June under the order of Major General William Howe. When the British Army marched in waves toward the Americans, Colonel William Prescott issued orders to avoid the fire until British troops came to clear sight in an attempt to protect the dwindling supply of ammunition to the Americans. Many British soldiers have been killed or maimed; the remainder has withdrawn down the hill. In a second wave, the British stormed the hill once again but met with the same fate. So they withdrew again, suffering a large number of casualties.  Eventually the British took the hill in the third attempt but at a great cost of casualties.

Answer:

d. at the same velocity

Explanation:

I will assume the car is also travelling westward because it was stated that the helicopter was moving above the car. In that case, it depends where the observer is. If the observer is in the car, the helicopter would look like it is standing still ( because both objects have the same velocity). If the observer is on the side of the road, both objects would be travelling at the same velocity. Also recall that, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes but speed is the rate at which object covers distance and it is not direction wise. Hence velocity is the best option.

Answer:

C. At the same speed

Answer:

[tex]Momentum(p) = 20kgm/s[/tex]

Explanation:

Given

Mass = 10kg

Velocity = 2m/s

Required

Calculate the momentum of the man

Momentum is calculated as thus

[tex]Momentum(p) = Mass(m) * Velocity(v)[/tex]

or

[tex]p = mv[/tex]

So; to solve this question; we simply substitute 10kg for mass and 2m/s for velocity in the above formula;

The formula becomes

[tex]Momentum(p) = 10kg * 2m/s[/tex]

[tex]Momentum(p) = 10 * 2 * kg * m/s[/tex]

[tex]Momentum(p) = 20kgm/s[/tex]

Hence, the momentum of the man is [tex]20kgm/s[/tex]

-- When you see the words "uniform speed", that means the car's speed is not changing.  

-- Right under those words in the picture, there's a note to remind you that "uniform speed" also means "acceleration is zero".

-- The whole key to this question is to find out if you remember that acceleration and net force always go together.  

.==> If there's net force, then there's acceleration.

.==> If there's acceleration, then there's net force.  

.==> If there's NO net force then there's NO acceleration.

.==> If there's no acceleration, then there's no net force.

-- In this picture, there's no acceleration, so there's no net force.

-- The driving force on the car is 2000N forward.

-- But the car's speed is not changing, so the net force on the car must be zero.

-- So that 'resisting' force pulling the car backwards must be 2000N. Then the net force on the car adds up to zero.

-- If the resisting force pulling the car backwards is not zero, then the net force on the car would not be zero, and the car's speed would be changing.

Answer:

Friction is a resistive force to motion. When two bodies move against each other some of the kinetic energy is converted to heat energy due to friction. This reduces the total kinetic energy in the system. ... Mechanical energy is reduced due to friction and converted to heat.

Explanation:

Kinetic friction does oppose the relative motion of two surfaces. If the one of these surfaces is stationary, then it will tend to slow down the moving object.

Answer:

B

Explanation:

Heat flows from hot to cold to lower the temperature of hot areas and increase temperature of cold areas. The end result is that the 2 areas have the same temperature, thus increasing entropy.

Heat flows spontaneously from hot to cold, and entropy increases.

The second law of thermodynamics relates to the entropy of a system. According to the second law of thermodynamics, the total entropy of a system may increase or remain constant in a spontaneous process.

The implication of this is that the entropy of a system never decreases. The entropy of a system increases when heat flows from a hot to a cold body and not vice versa.

Hence, the statement that; "Heat flows spontaneously from hot to cold, and entropy increases" describes the second law of thermodynamics.
