if the resistance of a car headlight is 15 ohm and the current through it is 0.60, what is the voltage across the headlight?

Answers

Answer:

9 volts (assuming 0.60 is in Amperes)

Explanation:

Recall that Ohms law can be expressed as

V = IR, where

V = voltage,

I = current (given as 0.6. I'm going to assume that the units is Amperes because it is not given)

R = resistance (given as 15 ohm)

substituting the above values into the formula

V = IR

V = (0.6)(15)

V = 9 Volts

Answer is 9 V you use Ohm’s Law to solve the problem

suppose that g (x) equals f (x + 1) - 3 which statement best compares the graph of g (x) with the graph of f (x)​

Answers

Answer:

The graph of G(x) is the graph of F(x) shifted 1 unit to the left and 3 units down.

Explanation:

f(x + q) which is left q units

f(x - q) which is right q units

f(x) + q which is up q units

f(x) - q which down q nits

and

G(x) = F(x + 1) - 3

So,

f(x + 1) shifts to left 1 unit

f(x) - 3 shifts to down 3 units

So, the correct answer is B.

The graph of G(x) is the graph of F(x) shifted 1 unit to the left and 3 units down.

A force acting on a body of mass 200g displace it through 200cm in 5s. Find the magnitude of the force if the initial velocity of is Zero​

Answers

Answer:

F = 0.32 N

Explanation:

GIVEN:

Mass = m =  200 g = 0.2 kg

Distance = S = 200 cm = 2 m

Time = t = 5 s

Initial velocity = U = 0 m/s

REQUIRED

Force = F = ?

SOLUTION

Using Second Equation of Motion,

S = Ut + 1/2 at²

2 = (0)(5) + 1/2 a(5)²

2 = 25/2 a

a = 4/25

a = 0.16 m/s²

So,

Acceleration = a = 0.16 m/s²

Now Using Equation from Newtons Second Law of Motion

F = ma

F = (2)(0.16)

F = 0.32 N

Answer:

The time between the emission of the wave and it's reception was 0.4 seconds.

Explanation:

The sound wave emitted by the sonar traveled from the boat to the fishes and came back, therefore the distance of it's total route is twice the distance from the boat to the fishes. We can apply the average speed formula in order to solve this problem, this is done below:

[tex]\text{speed} = \frac{\text{distance}}{\text{time}}[/tex]

We were given the distance traveled by the wave and it's speed, therefore we can solve for the time:

[tex]\text{time} = \frac{\text{distance}}{\text{speed}}\\\\\text{time} = \frac{(2*300)}{1500}\\\\\text{time} = \frac{600}{1500} = 0.4 \text{ s}[/tex]

The time between the emission of the wave and it's reception was 0.4 seconds.

Se realiza un trabajo mecanico de 3500 J para levantar una cubeta con area cuyo peso tiene una determinada magnitud. Determina la altura a la que se elevo la cubeta

Answers

Answer:

10 m

Explanation:

Trabajo (W) = 3500 J,   peso de la cuchara (F) = 350 N.

El trabajo es el producto de la fuerza que actúa sobre un objeto y la distancia o desplazamiento. La unidad de trabajo estándar son los joules (J).

Trabajo (W) =  fuerza (F) × distancia (d)

W = F × d

[tex]d=\frac{W}{F} =\frac{3500J}{350}=10m[/tex]

el cubo se elevó a 10 m

The height (distance) to which the bucket was raised is equal to 10 meters.

Given the following data:

Work done = 3500 JoulesWeight of bucket = 350 Newton

To determine the height (distance) to which the bucket was raised:

Mathematically, work done is given by the formula:

[tex]Work\;done = Force \times distance[/tex]

Substituting the given parameters into the formula, we have;

Note: Force = weight.

[tex]3500 = 350 \times distance\\\\Distance = \frac{3500}{350}[/tex]

Distance = 10 meters.

In a circuit, energy is transferred to a charge.
Where is this energy transferred from?

Answers

Answer:

Electric current.

Explanation:

The energy result from electric current resulting from potential differences between terminals which form an Electric circuit. This energy could come from different sources like chemical, wind, light

An electric circuit is one where there is movement of electrons;this electrons acquire charge which is energy. The electrons flow due to a potential difference; you have heard water flows from a higher position to a lower one freely. The highest height is said to be at higher potential and the lower point low potential.

So it's the same with electrons.

The formular for energy on charge is Q= I × t where I is electric current and t is time.

Can someone explain what ice jacking is and how it can cause structures to fail?

Answers

Answer: Rock slope failures can occur due to the presence of water; ice jacking occurs when water between joint or fissure surfaces freezes and expands. This type of failure is progressive, resulting in incremental weakening over time, often requiring several cycles before failure. Ice jacking is one form of rock erosion.

A metal rod has a moves with a constant velocity of 40 cm/s along two parallel metal rails through a magnetic field of 0.575 T. If the rails are separated by 20 cm, what is the power generated by the rod? O 341 x 1ow O 6.98 x 103 w O 9.00x 10sw O 8.10 x 105w

Answers

Answer:

2.12/R mW

Explanation:

The electrical power, P generated by the rod is

P = B²L²v²/R where B = magnetic field = 0.575 T, L = length of metal rod = separation of metal rails = 20 cm = 0.2 m, v = velocity of metal rod = 40 cm/s = 0.4 m/s and R = resistance of rod = ?

So, the induced emf on the conductor is

E = BLv

= 0.575 T × 0.2 m × 0.4 m/s

= 0.046 V

= 46 mV

The electrical power, P generated by the rod is

P = B²L²v²/R

=  B²L²v²/R

So, P = (0.575 T)² × (0.2 m)² × (0.4 m/s)²

= 0.002116/R W

= 2.12/R mW

Heat is supplied to convert 1.26 kg of water at 100°C to steam at 100°C? Latent heat of vaporization of water is
2.26 x 106 J/kg.
a
What is latent heat, and how does it affect the temperature of a substance?

Answers

Given that,

Mass of water = 1.26 kg

Latent heat of vaporization of water [tex]L=2.26\times10^{6}\ J/kg[/tex]

We need to calculate the latent heat

Using formula of latent heat

[tex]Q=mL[/tex]

Where, Q = energy

m = mass

L = latent heat of vaporization

Put the value into the formula

[tex]Q=1.26\times2.26\times10^{6}[/tex]

[tex]Q=2847600\ J[/tex]

[tex]Q=2.84\times10^{6}\ J[/tex]

The temperature changes liquid to steam.

So, The temperature will be increases.

Hence, The latent heat is [tex]2.84\times10^{6}\ J[/tex] and temperature increases.

The statement that best describes the long-term effects of using renewable resources is as follows:

As demand for renewable energy increases, fossil fuel use will decrease.

Thus, the correct option for this question is D.

What is meant by Renewable resources?

Renewable resources may be defined as those resources that cannot be exhausted and are capable in order to furnish a continuous source of clean energy. Examples include hydropower, geothermal power, wind energy, solar energy, etc.

The dependency on renewable resources reduces the demand for non-renewable resources like the combustion of fossil fuels that emit highly toxic constituents in the environment which are extremely harmful to living entities.

Therefore, as demand for renewable energy increases, fossil fuel use will decrease is the statement that best describes the long-term effects of using renewable resources. Thus, the correct option for this question is D.
