The trombone is a wind musical instrument and as all musical instruments can produce a standing (or stationary) wave.
This kind of waves is the result of the composition of two waves that produces a pattern that looks like it is not moving but just vibrating. Some points of the wave look like they are not even vibrating, they just stand still, and they are called nodes. Other points of the wave vibrate from the maximum positive value to the maximum negative value and are called antinodes.
I would say D is the right answer.
If the object is in an electromagnetic field, then it's movement can be generalized by interactions between charges.
By definition we have that the force for time is equal to the product of the mass for the change in speed.
We have then that
F * (delta t) = m * (delta v)
Clearing the mass
m = (F * (delta t)) / (delta v)
Substituting the values
m = ((3.00) * (4.00)) / (7.50-6.00) = 8
answer
The mass of the moving object is 8Kg
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).
Answer:
Explanation:
The mass of the deuteron = mass of the proton + mass of the neutron + mass equivalent of the energy of 2.2 Mev evolved.
I amu = 931 Mev
2.2 Mev = 2.2 / 931 amu
= ( 2.2 / 931 )x 1.6726 x 10⁻²⁷
= .00395 x 10⁻²⁷
The mass of the deuteron =( 1.6726 + 1.6749 + .00395)x 10⁻²⁷ kg
= 3.35145 x 10⁻²⁷ kg
b ) Momentum of gamma ray
= h / λ ( h is plank's constant and λ is wavelength of gamma ray )
= hυ / υλ ( υ is frequency of gamma ray )
= E / c ( E is energy of photon and c is velocity o light )
= 2.2 x 10⁶ x 1.6 x 10⁻¹⁹ J / 3 x 10⁸
= 1.173 x 10⁻²¹ Kg m /s
This will be the momentum of deuteron also
Kinetic energy
= p² / 2m ( p is momentum and m is mass of deuteron )
= ( 1.173 x 10⁻²¹ )² / ( 2 x 3.35145 x 10⁻²⁷)
= 1.376 x ⁻¹⁵ J
Energy of gamma ray
= 2.2 x 10⁶ x 1.6 x 10⁻¹⁹ J
= 3.52 x 10⁻¹³ J
So kinetic energy of deuteron is smaller than energy of gamma ray photon .
