If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.

A fisherman is watching water waves ripple past his boat. How could he determine the wavelength of the water waves?
natta225 [31]
Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength usually is expressed in units of meters.

Mechanical advantage of a first class Lever can be one or greater than one or less than one why​
erastovalidia [21]

Explanation:

Because they change the direction of force and multiply the effort.

They increase the rate of doing work.

So, MA of first class lever can be one or greater than one or less than one

A 3 kg object is moving along a horizontal surface. The kinetic energy of the object is increasing at a constant rate of 6 J/m;
Whitepunk [10]

To solve this problem we will apply the concepts of energy conservation and Newton's second law that defines force as the product of the object's mass with its acceleration. Additionally we will apply concepts related to the kinematics equations of linear motion.

For conservation of energy we have that work is equal to kinetic energy therefore,

W = KE

Fd = \frac{1}{2} mv^2

Here,

F = Force

d = Displacement

m = Mass

v= Velocity

At the same time we have the relation of

F = \frac{W}{d}

Therefore the value of the force can be interpreted as the rate of increase in energy per unit of distance, which makes it equivalent to

F = \frac{W}{d} = 6J/m

Applying Newton's Second Law

F = ma

6J/m = (3kg)a

a = 2m/s^2

In 4 seconds final velocity of the object becomes

v = at

v= 2*4

v= 8m/s

Then the work done is equal to,

W = KE

W = \frac{1}{2} mv^2

W = \frac{1}{2} (3)(82)

W = 96J

Then the displacement is,

W = F*d

d = \frac{W}{F}

d = \frac{96}{6}

d = 16 m

Therefore the distance moved is 16m
