Answer:

3 N to the right

Explanation:

There are two forces acting on the car:

- A force of 10 N towards the right

- A force of 7 N towards the left

Therefore, the net force is given by the difference between the two, since they are in opposite directions:

$F=10 N-7 N=3 N$

And the direction is to the right, since the force to the right has greater magnitude than the force to the left.

Nucleus A decays into the stable nucleus B with a half-life of 22.07 s. At t=0 s there are 1,293 A nuclei and no B nuclei. At wh

Alexeev081 [22]

Answer:

29.38 seconds

Explanation:

Half life, T = 22.07 s

No = 1293

Let N be the number of atoms left after time t

N = 1293 - 779 = 514

By the use of law of radioactivity

$N=N_{0}e^{-\lambda t}$

Where, λ is the decay constant

λ = 0.6931 / T = 0.6931 / 22.07 = 0.0314 decay per second

so,

$514=1293e^{-0.0314t}$

$2.5155=e^{0.0314t}$

take natural log on both the sides

0.9225 = 0.0314 t

t = 29.38 seconds

If a photon has a frequency of 5.20 × 1014 hertz, what is the energy of the photon? given: planck's constant is 6.63 × 10-34 jou

Inessa05 [86]

If a photon has a frequency of 5.20 × 1014 hertz, then the energy of the photon will be 3.45 x 10^-19 Joules.

<h3>What is photon energy?</h3>

The energy carried by a single photon is referred to as photon energy. The amount of energy is related to the electromagnetic frequency of the photon and consequently <u>inversely proportional t</u>o the wavelength. The higher the frequency of a photon, the greater its energy. The longer the wavelength of a photon, the lower its energy.

<h3>Given: </h3>

frequency = 5.20 × 10^(14) hertz

plank's constant = 6.63 × 10^-34 joule·seconds

<h3>Formula used:</h3>

E = hv

( where E = energy of the photon)

<h3>Solution: </h3>

E = 6.63 x 10 ^(-34) x 5.20 x 10^(14) = 34.476 x 10^ -19 Joules
