A car is moving in uniform circular motion. If the car's speed were to double to keep the car moving with the same radius, the acceleration wouldincrease by a factor of 2
increase by a factor of 4
decrease by a factor of 2
decrease by a factor of 4

Answers

Answer 1
Answer:

Answer:

Increase by a factor of 4.

Explanation:

The acceleration of a car moving with speed v in a circle of radius R is given by:

a=(v^2)/(R).

Now if we double the speed v in the equation above, it becomes 2v. Thus:

a=(v^2)/(R)\:\: {\rightarrow}\:\: a_n=((2v)^2)/(R)=4(v^2)/(R)=4a.

Therefore the acceleration is increased by a factor of 4.

The photos of an electromagnetic wave us 1. 5 × 10^-24 j of energy , what kind of electromagnetic waves are they ?

Answers

The electromagnetic waves with an energy of 1.5 * 10^(-24) J are likely X-rays.

The energy of an electromagnetic wave is related to its frequency and wavelength by the equation:

E = hf = hc/λ

where:

E = energy of the electromagnetic wave

h = Planck's constant (6.626 * 10^(-34) J s)

f = frequency of the electromagnetic wave

c = speed of light (3.00 * 10^8 m/s)

λ = wavelength of the electromagnetic wave

Solving for λ:

λ = hc/E = (6.626 * 10^(-34) J s)(3.00 * 10^8 m/s)/(1.5 * 10^(-24) J)

λ ≈ 4.40 * 10^-8 m

This corresponds to a wavelength of about 44 nanometers, which falls in the range of X-rays. Therefore, the electromagnetic waves with an energy of 1.5 * 10^(-24) J are likely X-rays.

Explain why a battery causes charge to flow spontaneously when the battery is inserted in a circuit

Answers

Batteries supply electrons to the circuit by releasing negatively charged atoms or ions. These ions are produced by the batteries through a chemical reaction that spontaneously occurs within the battery. So the negative end of the battery pushes the ions towards the positive end of the circuit with the help of the voltage. This is why eventually, batteries "run out" when the electrode is used up and the chemical reaction can no longer continue.
