I assume you mean fortnight? haha

Anyway, to answer this question, we need to have prior knowledge of time measurements. You should know that there are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day.

Therefore, if a fortnight is 14 days, we should multiply 14 by 24 to work out how many hours there are:

14 × 24 = 336 hours

Now, we should multiply 336 by 60 to work out the number of minutes:

336 × 60 = 20,160 minutes

And finally, we just need to multiply 20,160 by 60 again to work out the number of seconds:

20,160 × 60 = 1,209,600 seconds

And there you go! Your final answer is 1,209,600 seconds.

calculate the height from which a body is released from rest if its velocity just before hitting the ground is 30 metre per seco

Anna71 [15]

Answer:

height is 45 metres

Explanation:

KE=PE

¹/²mv² = mgh

¹/²v² = gh

but v =30m/s

(30)² / 2 =10h

450=10h

h = 45m

A soap bubble usually pops because some part of it becomes too thin due to evaporation or drainage of fluid. The change in thick

Lapatulllka [165]

Answer:

To understand why the change in thickness also changes the color of light the bubble reflects, we definitely know that

mλ = dsinθ

when d sin θ = mλ, we expect constructive interference

d = distance between the slits

θ = the angle relative to the incident direction

m = order of the interference

Hence, a change in the thickness will also cause a change in the wavelength, and as wavelength changes, various colors are generated.

The light's path difference is therefore generated as a result of the thickness variation of the soap bubble.

A man pushes his child in a grocery cart. The total mass of the cart and child is 30.0 kg. If the force resisting the carts moti

-BARSIC- [3]

The force applied by the man is 60 N

Explanation:

We can solve this problem by applying Newton's second law, which states that:

$\sum F = ma$ (1)

where

$\sum F$ is the net force acting on the child+cart

m is the mass of the child+cart system

a is their acceleration

In this problem, we have:

m = 30.0 kg is the mass

$a=1.50 m/s^2$

And there are two forces acting on the child+cart system:

The forward force of pushing, F
The force resisting the cart motion, R = 15.0 N

Therefore we can write the net force as

$\sum F = F -R$

where R is negative since its direction is opposite to the motion

So eq.(1) can be rewritten as

$F-R=ma$

And solving for F,

$F=ma+R=(30.0)(1.50)+15.0=60 N$

Sound of a known frequency, wavelength, intensity, and speed travels through air and bounces off an imperfect reflector which is

valkas [14]

Answer:

A) Speed

Explanation:

The medium of transmission(air) does not change before and after reflection. The sound still travels in air after the reflection. i.e the medium of transmission of sound is constant.

Since the medium of transmission remains constant, speed also remains constant. Speed only changes when the medium of transmission changes.
