What is the wavelength that corresponds to a frequency of 6.00x1014 hz?

1 answer:

4 0

The basic relationship between wavelength $\lambda$ , frequency f and speed c of an electromagnetic wave is
$\lambda= \frac{c}{f}$
where c is the speed of light. Substituting numbers, we find:
$\lambda= \frac{c}{f}= \frac{3 \cdot 10^8 m/s}{6.0 \cdot 10^{14} Hz}=5\cdot 10^{-7} m$

A world class sprinter can accelerate at 5.0 m/s squared, from the rest in the starting blocks to their top speed in 4.0 seconds

Airida [17]

Answer:

The distance covered by the sprinter, s = 40 m

Explanation:

Given data,

The initial velocity of the sprinter, u = 0 m/s

The acceleration of the sprinter, a = 5 m/s²

The time period of acceleration of the sprinter, t = 4 s

Using the II equations of motion

s = ut + ½ at²

= 0 + ½ (5) (4)²

= 40 m

Hence, the distance covered by the sprinter, s = 40 m

Consider a railroad bridge over a highway. A train passing over the bridge dislodges a loose bolt from the bridge, which proceed

schepotkina [342]

Answer:

12.35m

Explanation:

Hello! To solve this problem we must consider the following:

1. The car moves with constant speed, which means that the distance traveled is equal to the multiplication of time by speed.

X = VT

we solve the equation for time

$T=\frac{x}{V} =\frac{27}{17} =1.588s$

2. The bolt moves with constant acceleration, with acceleration of 9.81m / s ^ 2, so we could apply the following equation.

note=remember that "a uniformly accelerated motion", means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.

$Y= VoT-\frac{1}{2}gt^{2}$

where

Vo = Initial speed

T = time

=1.588s

g =gravity=9.8m/s^2

Y = bridge height

solving

$Y= \frac{1}{2}gt^{2}\\Y=(0.5)(9.8)(1.588^2)=12.35m$

Which of the following statements about an apple falling from a tree is true? A) Its kinetic energy decreases and its potential

xenn [34]

Your answer would be B because potential energy is an object's potential to move while kinetic energy is the energy of the object in motion. So if the apple is falling, then the potential energy would decrease and its kinetic energy would increase.

Hope this helps :)
