An electron and a proton are each accelerated from rest through a potential difference of 100 V. Afterward, which particle has t

Lena [83]

Explanation:

The De-Broglie wavelength in terms of potential difference is given by:

$\lambda=\dfrac{h}{\sqrt{2meV} }$

Where,

h is Planck's constant

m is mass of charged particle

V is potential difference

e is the amount of charge

It means that the De-Broglie wavelength is inversely proportional to the mass.

Since, the mass of the proton is more than the mass of the electron. So, the De- Broglie wavelength of the electron is larger than proton.

Two students, standing on skateboards, are initially at rest, when they give each other a shove! After the shove, one student (7

Elden [556K]

Answer:

The other student (59kg) moves right at 7.44 m/s

Explanation:

Given;

mass of the first student, m₁ = 77kg

mass of the second student, m₂ = 59kg

initial velocity of the first student, u₁ = 0

initial velocity of the second student, u₂ = 0

final velocity of the first student, v₁ = 5.7 m/s left

final velocity of the second student, v₂ = ? right

Apply the principle of conservation of linear momentum;

Total momentum before collision = Total momentum after collision

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(77 x 0) + (59 x 0) = (-77 x 5.7) + (59 x v₂)

0 = - 438.9 + 59v₂

59v₂ = 438.9

v₂ = 438.9 / 59

v₂ = 7.44 m/s to the right

Therefore, the other student (59kg) moves right at 7.44 m/s

A team of eight dogs pulls a sled with waxed wood runners on wet snow (mush!). The dogs have average masses of 19.0 kg, and the

liberstina [14]

Answer

given,

number of dog = 8

mass of each dog= 19 Kg

mass of sled = 210 Kg

average force = 185 Nss

a) writing all the horizontal force

force acting by dog - friction force = (M + 8m) a

8 F_d - μ m g = (M + 8m) a

assuming coefficient of friction of snow be μ = 0.14

8 x 185 - 0.14 x 210 x 9.8 = (210 + 8 x 19 ) x a

a = 3.29 m/s²

b) the kinetic friction of coefficient is less than static friction

hence, we can suggest that acceleration of the sled will increase once the sled start to move.

a > 3.29 m/s²

Which of these results from destructive interference?

Mazyrski [523]

Based on the options given, the answer is two waves subtract from each other. Destructive interference happens when two waves meet each other however with different frequencies cancel each other out.
