<span>We consider that my calculator has the following dimensions (approx) :
Length = 14 cm
Width = 7 cm
Heigth= 2 cm
Then the volum of the calculator will be V=Length x Width x Height = 196 cm3
If we assume that my calculator has the same density of water, that is 1 g/cm3
that means my calculator mass is:
M = 196 cm3 * 1 g/cm3 = 196 grams</span>
So, the force that given when the wagon was being pulled is approximately <u>19.1 N (C)</u>.
<h3>Introduction</h3>
Hi ! For intermesso, this question will adopt a lot about the relationship of impulse to change in momentum. <u>Impulse is the total force applied in a certain time interval</u>. Impulses can cause a change of momentum, because momentum itself <u>is a mass that is affected by the velocity of an object</u>. We know that velocity is a vector quantity easy to change its direction. The relationship between impulse and change in momentum is formulated by :
With the following condition :
- I = impulse that given (N.s)
- = change of momentum (kg.m/s)
- F = force that given (N)
- m = mass of the object (kg)
- v = initial velocity (m/s)
- v' = final velocity (m/s)
- = interval of the time (s)
<h3>Problem Solving</h3>
We know that :
- m = mass of the object = 25 kg
- v = initial velocity = 0 m/s
- v' = final velocity = 1.8 m/s
- = interval of the time = 2.35 s
What was asked :
- F = force that given = ... N
Step by step :
<h3>Conclusion</h3>
So, the force that given when the wagon was being pulled is approximately 19.1 N (C).
I't a called a Blank. Because it's between 2 boundaries called blank wave. It occurs when two waves travel through the same space simultaneously.
Answer:
In a way of energy “1s” subsell contains most energy. because 1 s subsell contains the electrons of K orbital which is nearest from the nucleus. so the order of energy will be 1s>2s>2p> 3s> 3p> 4s> 3d> 4p> 5s> 4d> 5p> 6s> 4f> 5d> 6p> 7s and the increasing order of thair energies will be- 4s <3d<4p<5s<4d<5p<6s<4f.
