How often the particles vibrate about their fix position"

Physics
1 answer:
Wewaii [24]4 years ago
6 0

Answer:As an example, a wave with a period T = 0.25 s takes ¼ of a second to complete a full vibration cycle (crest - trough - crest) at a certain location and thus performs four vibrations per second. Hence its frequency is f = 4 Hz.

5. An infinite wire is 3.00 cm away from and parallel to a 10 cm long wire, and each has a current of 2.50 A in the same directi
Step2247 [10]

Answer:

B=1.04*10^{-4}T

Explanation:

An infinite wire produces a magnetic field that can be computed with the formula:

B=\frac{\mu_0 I}{2\pi r}

where m0 is the magnetic permeability of vacuum (4pi*10^{-7}Tm/A), I is the current of the wire (2.50A) and r is the perpendicular distance to the wire in which B is calculated (3cm=3*10^{-2}m). By replacing we obtain:

B=\frac{(4\pi*10^{-7}Tm/A)(2.50A)}{3*10^{-2}m}=1.04*10^{-4}T

hope this helps!!

Two balls of equal mass collide and stick together as shown in the figure. The initial velocity of ball B is twice that of ball
Mice21 [21]

The angle above the horizontal of the motion of mass A + B after the collision. as well as others are mathematically given as

  • \theta f = 26.3 \deg
  • vf/vA= 0.94
  • 2vf^2 / 5vA^2 = 0.35

<h3>What is  Collison equilibrium?</h3>

According to the collision hypothesis of chemistry, chemical reactions happen when two molecules or atoms collide.

Generally, the equation for Collison equilibrium is  mathematically given as

For horizontal motion

mvAx+m2vAx = 2mvfx

For vertical motion

-mvAy+m2vAy = 2mvfy

vfy = 1/2 vAy

\tan \theta f = vfy/vfx \\\\\tan \theta f = 1/3 vAy/vAx \\\\\tan \theta f  = vAy/vAx \\\\\theta f = tan-1 ( 1/3 tan (56) )\\\\

\theta f = 26.3 \deg

(b)

v fy = vf sin \theta f\\\\vAy = vA sin theta i\\\\vf/vA = vfy/vAy sin( \theta i)/sin(\theta f)\\\\vf/vA = 1/2 sin(56)/sin(26.3) \\\\

vf/vA= 0.94

(c)

Ef/Ei = \frac{(1/2 * (2m) * (vf)^2) }{ (1/2 * m * (vA)^2) + 1/2*m*(2vA)^2) ]}

2vf^2 / 5vA^2 = 0.35

In conclusion, The angle above the horizontal of the motion of mass A + B after the collision. as well as others

\theta f = 26.3 \deg

vf/vA= 0.94

2vf^2 / 5vA^2 = 0.35

When the plutonium bomb was tested in New Mexico in 1945, approximately 1 gram of matter was converted into energy. Suppose anot
Softa [21]

Answer:

1.08 * 10^{14} J

Explanation:

Energy and mass are related by the famous equation developed by Albert Einstein:

E = mc^2

where m = mass and c = speed of light

This equation explains that an object with very small mass can produce a large amount of energy in reactions such as a nuclear reaction.

Hence, the energy produced by the explosion of a Plutonium bomb containing 3.6 grams of matter is:

E = 3.6 * 10^{-3} * (3 * 10^8)^2

E = 1.08 * 10^{14} J
