When fossil are burned, their chemical potential energy is converted into?

Answers

Answer 1

Answer: Fossil fuel is a source of non-renewable energy. There are many examples of fossil fuels which we use in our daily lives. In fact, most of the energy that we consume is fossil fuels. Coal, petroleum, natural gas, these are all considered as fossil fuels. Many years ago, to be specific, during the carboniferous age, due to the change in atmospheric condition and other changes, there forests were destroyed and they were fossilized. With the action of bacteria and other microorganisms in the surface of the earth, these trees and other vegetation were decayed and disintegrated. Years after these trees were available in solid, liquid and gaseous state. The solid form is coal. It is the most widely used form of fossil fuel in domestic purposes.

How much voltage would be necessary to generate 10 amps of current in a circuit that has 5 ohms ofresistance?

Answers

Voltage would be necessary to generate 10 amps of current in a circuit that has 5 ohms of resistance will be 50 V

What is ohm's law ?

Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance

using ohm's law

V = IR

V = voltage in a circuit = ?

I = current = 10 A

R = Total resistance in the circuit = 5 ohm

V = IR

= 10 A * 5 ohm

= 50 V

Which of the following is true about light with a single wavelength?1) It can be refracted
II) It cannot be dispersed
III) It can be reflected *

Answers

Answer:

It can be refracted

Explanation:

When a single wavelength wave which is known as a monochromatic light is passed from one transparent medium to the other, it can refract. This refraction can only be seen if the light enter the medium at some angle.

Calculate the speed of the ball, vo in m/s, just after the launch. A bowling ball of mass m = 1.5 kg is launched from a spring compressed by a distance d = 0.21 m at an angle of θ = 32° measured from the horizontal. It is observed that the ball reaches a maximum height of h = 4.4 m, measured from the initial position of the ball. Let the gravitational potential energy be zero at the initial height of the bowling ball.

Answers

Answer:

$v_0=17.3m/s$

Explanation:

In this problem we have three important moments; the instant in which the ball is released (1), the instant in which the ball starts to fly freely (2) and the instant in which has its maximum height (3). From the conservation of mechanical energy, the total energy in each moment has to be the same. In (1), it is only elastic potential energy; in (2) and (3) are both gravitational potential energy and kinetic energy. Writing this and substituting by known values, we obtain:

$E_1=E_2=E_3\n\nU_e_1=U_g_2+K_2=U_g_3+K_3\n\n(1)/(2)kd^2=mg(d\sin\theta)+(1)/(2)mv_0^2=mgh+(1)/(2)m(v_0\cos\theta)^2$

Since we only care about the velocity $v_0$ , we can keep only the second and third parts of the equation and solve:

$mgd\sin\theta+(1)/(2)mv_0^2=mgh+(1)/(2)mv_0^2\cos^2\theta\n\n(1)/(2)mv_0^2(1-\cos^2\theta)=mg(h-d\sin\theta)\n\nv_0=\sqrt{(2g(h-d\sin\theta))/(1-\cos^2\theta)}\n\nv_0=\sqrt{(2(9.8m/s^2)(4.4m-(0.21m)\sin32\°))/(1-\cos^232\°)}\n\nv_0=17.3m/s$

So, the speed of the ball just after the launch is 17.3m/s.

What happens to the current flowing through a circuit as resistance increases?

Answers

As resistance increases in a circuit, the current flowing through the circuit decreases.

This is because resistance opposes the flow of current, so as resistance increases, it becomes more difficult for the current to flow.

This is described by Ohm's Law, which states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance.

Therefore, as resistance increases, the current must decrease in order to maintain the same voltage in the circuit.
