calcula el peso de un perro cuya masa es de 25 kg en la tierra

Answers

Answer:

El peso = 245 Newton

Explanation:

Dados los siguientes datos;

Masa = 25 kg

Para encontrar el peso del perro en la tierra;

El peso se puede definir como la fuerza que actúa sobre un cuerpo o un objeto como resultado de la gravedad.

Matemáticamente, el peso de un objeto viene dado por la fórmula;

[tex] El \; peso = mg [/tex]

Dónde;

m es la masa del objeto.

g es la aceleración debida a la gravedad.

Sabemos que la aceleración debida a la gravedad es igual a 9,8 m / s² en el planeta Tierra.

Sustituyendo en la ecuación, tenemos;

[tex] W = 25 * 9.8[/tex]

El peso = 245 Newton

Coulomb's Law describes the relationship between electromagnetic force and the distance between charges.

What is the relationship between electromagnetic force and the distance between charges?

The relationship between electromagnetic force and the distance between charges is described by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, Coulomb's Law is expressed as:

F = k  (q₁x q₂) / r²

where F is the electromagnetic force, q1 and q2 are the charges, r is the distance between the charges, and k is the Coulomb constant.

This means that as the distance between two charges increases, the force between them decreases, and as the distance decreases, the force increases. The relationship between force and distance is inverse square, which means that the force decreases rapidly as the distance increases.

A resistor of 500Ω and one of 2000Ω are placed in series with a 60V supply. What will be the reading on a voltmeter of internal resistance 2000Ω when placed across (i) 500Ω resistor and (ii) 2000Ω resistor?

Answers

Answer: 10 V, 40 V

Explanation:

Given

Resistors are [tex]500\Omega[/tex] and [tex]2000\Omega[/tex]

Power supply [tex]V=60\ V[/tex]

Voltmeter internal resistance [tex]r=2000\ \Omega[/tex]

When it connected around [tex]500\Omega[/tex] resistance, effective resistance becomes

[tex]\Rightarrow \dfrac{1}{R}=\dfrac{1}{500}+\dfrac{1}{2000}\\\\\Rightarrow R=\dfrac{2000}{5}\\\\\Rightarrow R=400\ \Omega[/tex]

Total resistance in series [tex]R_{net}=2400\ \Omega[/tex]

Current in circuit

[tex]I=\dfrac{60}{2400}=\dfrac{1}{40}\ A[/tex]

Voltage around [tex]500\Omega[/tex] resistance is

[tex]V=\dfrac{1}{40}\times 400\\\\V=10\ V[/tex]

(B) when voltmeter is connected around [tex]2000\Omega[/tex]  resistor

Net resistance around it

[tex]\Rightarrow \dfrac{1}{R}=\dfrac{1}{2000}+\dfrac{1}{2000}\\\\\Rightarrow R=1000\ \Omega[/tex]

Total resistance [tex]R_{net}=1500\ \Omega[/tex]

Current in circuit

Let FAB, be the force exerted on body B by body A and FBA be the force exerted by body B on A. Suppose that due to these forces FAB and FBA, dp1/dt and dp2/dt be the rate of the change of momentum of these bodies respectively.

Answer:

Consider an isolated system of 2 bodies A & B. An isolated system means where there is no external force acting.Now let F be the force acting on B by A & F be the force acting on A by B.Now rate of change of momentum of A =dpA/dt and rate of change of momentum of B =d pB/dt

thus FAB=d pB/dt (i)......

FBA=dpA/dt (ii)........

Adding 1 and 2 we get FAB+FBA=d pB/dt+dpA/dt =d(pB+pA)/dt

But if no force is applied momentum will also be 0 because no velocity will be there so rate of change of momentum will also be 0

thus d(pA+pB)/dt=0

therefore FAB+FBA=0

or,FAB=-FBA

Find new resistance of wire if it is stretched to twice its
original length. Original resistance was 20 ohm. Also how its
resistivity will change

Answers

Answer:

Original Length = L1

Stretched length =L2

From

R = pl/A

R=Resistance

p=Resistivity

A=Cross-sectional Area

l= length of wire

We can see that Resistance is directly Proportional to Length... Meaning that Resistance Increases also as Length increases.

R1/L1 = R2/L2

From the question... The key to note is this sentence

"The Stretched length is TWICE the Original Length"

Meaning

L2 = 2L1 (So replace L2 as 2L1 when solving)

R1=20ohms

Let R2 = k

Applying the formula

20/L1 = k/2L1

kL1 = 20x 2 L1

KL1 = 40L1

L1 cancels on both sides

k=40ohms.

So As the length doubled... The Resistance did too

from 20ohms to 40ohms

Magali exerts a force of 4.5 N to slide her Blackberry across the table (so she can hide it from Hina!). If she does 2.7 J of work in the process, how far has the Blackberry moved?

Answers

Work is equal to the magnitude of the force multiplied by the displacement x. Assuming Magali is pushing the phone, so that the force and displacement point in the same direction, then the work done is positive, and

2.7 J = (4.5 N) x   ==>   x = (2.7 J) / (4.5 N) = 0.60 m

Even if she was pulling the phone instead, the displacement would be the same, but the work done would be negative and the force would point in the opposite direction, thus also having a negative sign:

-2.7 J = (-4.5 N) x   ==>  x = 0.60 m

Spaceship 1 and Spaceship 2 have equal masses of 150 kg. Spaceship 1 has an initial momentum magnitude of 900 kg-m/s. What is its initial speed?
A. 9 m/s
B. 6 m/s
C. 90 m/s
D. 60 m/s

Answers

Answer:

ans: 6 m/s

Explanation:

spaceship 1 has mass= 150kg

initial momentum of spaceship 1 = 900 kg•m/s

we know,

momentum = mass × velocity

so,

velocity = momentum/mass

= 900 / 150

= 6 m/s

since we know it was initial momentum so, velocity is initial speed,

Explanation:

Air pollution is an example of a. The underground economy. B. An external shock. C. A nonmarket activity. D. A negative externality.

Answers

Answer:

D. A negative externality.

Explanation:

Particulate pollution is a form of pollution that is responsible for the degradation of the environment.

Particulate matter is also referred to as particle pollution or atmospheric aerosol particles and it can be defined as a complex microscopic mixture of liquid droplets and solid particles that are suspended in air.

An externality is typically an unwarranted cost or benefit by a manufacturer or producer of goods and services that affects a third party.

In Economics, an externality could either be positive or negative depending on its effect on a third party.

A negative externality arises when the production or consumption of a finished product or service has negative impact (cost) on a third party.

In conclusion, air pollution is an example of a negative externality because it causes harm to a third party.

how can you reduce output voltage to 6v in transformers if the input voltage is 240v​

Answers

Answer:

[tex]N_P = 40\ N_S[/tex]

To reduce the output voltage to 6v in transformers if the input voltage is 240v​, we need to have 40 times as many turns in the primary coil as there are in the secondary coil.

Explanation:

The change in voltage of a transformer depends upon the turns ratio of the transformer between secondary and primary coil. Following formula can be used to determine the turns ratio in this case:

[tex]\frac{N_P}{N_S} = \frac{V_P}{V_S} \\\\[/tex]

where,

[tex]N_P[/tex] = No. of turns in the primary coil

[tex]N_S[/tex] = No. of turns in the secondary coil

[tex]V_P[/tex] = voltage in the primary coil = 240 V

[tex]V_S[/tex] = voltage in the secondary coil = 6 V

Therefore,

[tex]\frac{N_P}{N_S} = \frac{240\ V}{6\ V} \\\\N_P = 40\ N_S[/tex]

To reduce the output voltage to 6v in transformers if the input voltage is 240v​, we need to have 40 times as many turns in the primary coil as there are in the secondary coil.
