Suppose an automobile has a kinetic energy

Physics
1 answer:
enyata [817]4 years ago
4 0

Answer:

Explanation:

Given that,

Kinetic energy of an automobile is 2300J

K.E = 2300J

The formula for kinetic energy is

K.E = ½mv²

So, if the speed of the automobile is increased by 6, what is the kinetic energy

Now v' = 6v.

The mass of the automobile is constant.

Therefore, the kinetic energy is

K.E' = ½mv'²

Where v' = 6v

K.E' = ½m(6v)²

K.E' = ½m × 36v²

K.E' = 36 × ½mv²

Where, from above ½mv² = 2300J

Then,

K.E' = 36 × 2300 = 82,800J

The kinetic energy of the automobile when it increase it's speed is 82,800J

The four lines observed in the visible emission spectrum of hydrogen tell us that
Gemiola [76]

Answer:

The correct answer is violet, blue, green, and red emission lines.

Explanation:

When samples of pure elements are heated they emit a continuous spectrum of electromagnetic radiation. When elements are heated at very high temperatures, the electrons get excited and they jump to consequent orbits and this results in transmission of electromagnetic radiation. The four lines visible in the emission spectrum of hydrogen are violet, blue, green, and red, the most intense of which is at 656 nanometre.

a quantity of water is poured into a graduated cylinder, which reads 139 mL. what is the mass of the water in kilograms?​
alexgriva [62]

The mass of water is 0.139 kg

Explanation:

The density of a substance is given by the equation

\rho = \frac{m}{V}

where

\rho is the density

m is the mass of the substance

V is its volume

In this problem we have:

V = 139 mL is the volume of water

The density of water is:

\rho = 1 g/mL

Solving the equation for m, we find its mass:

m=\rho V = (1.0)(139)=139 g

And converting into kilograms,

m=139 g = 0.139 kg
