Answer:

the voltage across each resistor is one third of the battery voltage

Explanation:

In a series circuit, the current is constant throughout the circuit, so the battery voltage is equal to the sum of the voltage drop in each part of the series circuit.

        V = i (R₁ + R₂ + R₃)

in the exercise indicate that all resistance has the same value

         R₀ = R₁ = R₂ = R₃

        V = i 3 R₀

        V = 3 V₀

         V₀ = i R₀

          V₀= V / 3

the voltage across each resistor is one third of the battery voltage

Answer:

Properties of an Electric Field

Field lines never intersect each other. They are perpendicular to the surface charge. The field is strong when the lines are close together, and it is weak when the field lines move apart from each other. The number of field lines is directly proportional to the magnitude of the charge.

Answer:

[tex]p=10\:\text{kgm/s}},\\v_f=1\:\text{m/s}[/tex]

Explanation:

From Newton's 2nd Law, we have [tex]\Sigma F=ma[/tex]. We can use this to find the acceleration of object after 20 N (force) is applied to the 10 kg object.

Substituting given values, we have:

[tex]\Sigma F=ma, \\20=10a,\\a=\frac{20}{10}=2\:\mathrm{m/s^2}[/tex]

Now that we have acceleration, we can find the final velocity of object (after 0.5 seconds) using the following kinematics equation:

[tex]v_f=v_i+at[/tex], where [tex]v_f[/tex] is final velocity, [tex]v_i[/tex] is initial velocity, [tex]a[/tex] is acceleration, and [tex]t[/tex] is time.

Solving for final velocity:

[tex]v_f=0+2\cdot 0.5,\\v_f=\boxed{1\:\text{m/s}}[/tex]

The momentum of an object is given as [tex]p=mv[/tex]. Since we've found the final velocity and mass stays constant, we have:

[tex]p=10\cdot 1=\boxed{10\:\text{kgm/s}}[/tex]

Answer:

7/3 = 2 1/3

Explanation:

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction. 7/3 = 2 1/3.

Option B

Explanation:

Answer:

You need to have the distance traveled and the time it took to travel that distance.

Explanation:

Answer:

c) 100,000 m/s

Explanation:

You need to take the same wave length from the top graph and bottom one, so let's take half a wave length then in the top one that is 0.005, but in the bottom one it's 2000/4 = 500 because they are smaller and there are 4 half waves before you get to 2000, whereas in the top one there is 1 half wave before you get to 0.005 on the graph.

Now use speed = distance / time

speed = 500 / 0.005 = 100 000 m/s

Answer:

Parte A

2000 J

Parte B

400 N

Parte C

900 N

Explanation:

Los parámetros dados son;

La fuerza horizontal con la que la persona arrastra los muebles = 400 N

El peso de los muebles = 900 N

La distancia que se mueve el mueble en el piso = 5 m

El tipo de movimiento del mueble = M.R.U. Movimiento de línea uniforme

Por lo tanto;

Parte A

Trabajo realizado = Fuerza × Dirección de movimiento de la fuerza

Por lo tanto;

Trabajo realizado en, W = 400 N × 5 m = 2000 J

Parte B

La fuerza horizontal aplicada para arrastrar el mueble = 400 N = La fuerza de fricción que actúa sobre el mueble

La fuerza de fricción que actúa sobre el mueble = 400 N

Parte C

El peso de los muebles se toma como dado 900 N.

Answer:

if a uniform resistance wire is stretched till it's length becomes four times the the resistance of wire multiples by sixteen times as resistance is directly proportional to the

length of wire.

hope it helps.

Answer:

we have:

At unit length

Resistance [R]=[tex] \frac{pL}{A} [/tex].....i

where

p: resistivity

L:length

A:area

when

length is strength 4 times

length will be 4L

Now

new equation becomes

Resistance[R] =[tex] \frac{p4L}{A} [/tex]=4[tex] \frac{pL}{A} [/tex]=4R

so

when A uniform resistance wire is stretched till it's length becomes four times. the resistance increases by four times of its original resistance.

Explanation:

This exposes the individual to danger. Remember, the Newton Law of motion which says that an object under the state of rest will remain in that state (inertia) unless when acted upon by an external force.

In this scenario, standing at the back of the pickup truck presents danger especially if the truck suddenly stops; this individual would experience an upward thrust due to inertia that may disbalance him.

Explanation:

The period of the dripping faucet is 0.8 seconds per drip cycle.

The rate is a measure of how much something changes over time and is typically expressed as a ratio of two quantities with different units of measurement.

Here,
The period of a dripping faucet is the time it takes for one complete drip cycle. To find the period, we need to divide the total time by the number of drip cycles.

In this case, the faucet drips 150 times in 120 seconds, so the time for one drip cycle is,

120 seconds / 150 drips = 0.8 seconds/drip

Therefore, the period of the dripping faucet is 0.8 seconds per drip cycle.

Answer:

The average speed can be calculated as the quotient between the distance travelled and the time needed to travel that distance.

To go to the school, he travels 2.4 km in 0.6 hours, then here the average speed is:

s = (2.4km)/(0.6 hours) = 4 km/h

To return to his home, he travels 2.4km again, this time in only 0.4 hours, then here the average speed is:

s' = (2.4 km)/(0.4 hours) = 6 km/h.

Now, if we want the total average speed (of going and returning) we have that the total distance traveled is two times the distance between his home and school, and the total time is 0.6 hours plus 0.4 hours, then the average speed is:

S = (2*2.4 km)/(0.6 hours + 0.4 hours)

S = (4.8km)/(1 h) = 4.8 km/h

Answer: [tex]18.798\times 10^5\ J[/tex]

Explanation:

Given

Mass of snow is [tex]m=3\ kg[/tex]

First snow is converted to water at [tex]0^{\circ}C[/tex] and then it is taken to [tex]70^{\circ}C[/tex]

Heat required to convert the ice into water at [tex]0^{\circ}C[/tex]

[tex]Q_1=3\times 3.34\times 10^5\\Q_1=10.02\times 10^5\ J[/tex]

Heat required to raise temperature from [tex]0^{\circ}C[/tex] to [tex]70^{\circ}C[/tex]

[tex]Q_2=3\times 4180\times (70-0)\\Q_2=8.778\times 10^5\ J[/tex]

Total heat required

[tex]\Rightarrow Q=Q_1+Q_2\\\Rightarrow Q=10.02\times 10^5+8.778\times 10^5\\\Rightarrow Q=18.798\times 10^5\ J[/tex]

Answer:

11.78meters

Explanation:

Given data

Mass m = 100kg

Length of cord= 10m

Spring constant k= 35N/m

At the greatest vertical distance, the spring potential energy is equal to the gravitational potential energy

That is

Us=Ug

Us= 1/2kx^2

Ug= mgh

1/2kx^2= mgh

0.5*35*10^2= 100*9.81*h

0.5*35*100=981h

1750=981h

h= 1750/981

h= 1.78

Hence the bungee jumper will reach 1.78+10= 11.78meters below the surface of the bridge

Answer:

[tex]X=74.7[/tex]

Explanation:

From the question we are told that:

Mass [tex]m=100kg[/tex]

Length [tex]l=10m[/tex]

Spring constant [tex]\mu=35N/m[/tex]

Generally the equation for potential energy of mass is mathematically given by

 [tex]P.E_m=mgh[/tex]

Since

 [tex]P.E_m=P.E_s[/tex]

Where

 P.E_s =potential energy of spring

Therefore

[tex]m*g*(x+10) = 0.5*k*\mu^2[/tex]

[tex]100*9.8*(x+10) = 0.5*35*\mu^2[/tex]

[tex]980*(x+10) = 17.5*\mu^2[/tex]

[tex]980*x+9800 = 17.5*\mu^2[/tex]

 [tex]17.5*\mu^2 - 980*\mu - 9800 = 0[/tex]

Comparing the equation above with standard quadratic equation

 [tex]17.5*\mu^2 - 980*\mu - 9800 = 0[/tex]

 [tex]ax^2+bx+c=0[/tex]

Giving

  [tex]a=17.5\\ b=-980\\ c=-9800[/tex]

Solving Quadratic equation the roots of the equation is given as

 [tex]\mu_1=64.66[/tex]

 [tex]\mu_2=-8.661[/tex]

Since

[tex]\mu[/tex] can not be -ve

Therefore

The vertical distance attained by the bungee jumper is given as

 [tex]X=\mu+l[/tex]

 [tex]X=64.7+10[/tex]

 [tex]X=74.7[/tex]

[tex]45=93+5.3a,\\-48=5.3a,\\a\approx \boxed{-9.06\mathrm{m/s^2}}[/tex]

*Note: Since acceleration is a vector quantity, it has both magnitude and direction. The negative sign implies that the acceleration is in the opposite direction of the racing dragster's movement.

Answer:

Increases.

Explanation:

The electric potential increases when the two positive charges of same magnitude bring close to one charge to another because there is repulsive force between them due to same charge and when the two opposite charges move away from each other, the potential energy decreases. When two opposite charges are brought closer together, electric potential energy decreases while on the other hand, when we move opposite charges apart from each other than the work done against the attractive force that leads to an increase in electric potential energy.
