What is the energy of a photon whose frequency is 6.0x10^20 hz?

Answers

Answer 1

Answer:

Energy of photon is given by formula

$E = h\nu$

here

h = Planck's constant

$h = 6.6* 10^(-34)$

$\nu = frequency = 6 * 10^(20)Hz$

now the energy is given by

$E = 6.6*10^(-34) * 6 * 10^(20)$

$E = 3.96 * 10^(-13) J$

Answer 2

Answer: give me some answer choices and i will be happy to help

If you throw a ball up with a velocity of 7 m/s, how long will it take for the ball to reach the top of its path?A. 0.11 Seconds
B. 0.41 Seconds
C. 0.71 Seconds
D. 1.01 Seconds

Answers

Answer:

c. 0.71 [s]

Explanation:

To solve this problem we must use the following equation of kinematics.

$v_(f) =v_(o) -g*t$

where:

Vf = final velocity = 0 (because when the ball reaches the top, there is no movement)

Vo = initial velocity = 7 [m/s]

g = gravity acceleration = 9.81 [m/s²]

t = time [s]

Note: The negative sign of the equation means that the movement is againts the direction of the gravity acceleration.

$0 = 7 - (9.81*t)\nt = 0.713 [s]$
