Answer:

Helium nucleus

Explanation:

Alpha particles have two protons and two neutrons, wich is the configuration of an Helium Nucleus.

The atomic number of an element it is the number of protons that the element has in its nucleus, this number is uniqe to every element. Helium is the second element in the periodic table so Its atomic number is 2, This means it has two protons and the same amount of neutrons, wich makes alpha particles identical to a helium nucleus, not to a Helium atom, because a Helium atom has electrons and alpha particles don't have electrons.

A point on the string of a violin moves up and down in simple harmonic motion with an amplitude of 1.24 mm and frequency of 875
mario62 [17]

Using

V = Amplitude x angular frequency(omega)

But omega= 2πf

= 2πx875

=5498.5rad/s

So v= 1.25mm x 5498.5

= 6.82m/s

B. .Acceleration is omega² x radius= 104ms²

A steel tank of weight 600 lb is to be accelerated straight upward at a rate of 1.5 ft/sec2. Knowing the magnitude of the force
VikaD [51]

Answer:

a) the values of the angle α is 45.5°

b) the required magnitude of the vertical force, F is 41 lb

Explanation:

Applying the free equilibrium equation along x-direction

from the diagram

we say

∑Fₓ = 0

Pcosα - 425cos30° = 0

525cosα - 368.06 = 0

cosα = 368.06/525

cosα = 0.701

α = cos⁻¹ (0.701)

α = 45.5°

Also Applying the force equation of motion along y-direction

∑Fₓ = ma

Psinα + F + 425sin30° - 600 = (600/32.2)(1.5)

525sin45.5° + F + 212.5 - 600 = 27.95

374.46 + F + 212.5 - 600 = 27.95

F - 13.04 = 27.95

F = 27.95 + 13.04

F = 40.99 ≈ 41 lb

A 10 µf capacitor is charged to 108 v and is then connected across a 328 ω resistor. what is the initial charge on the capacitor
valina [46]
The capacitance is defined as the maximum charge stored in a capacitor, Q, divided by the voltage applied, V:
C= \frac{Q}{V}

The capacitor is initially charged with the battery of 108 V, so the the initial charge on the capacitor can be found by re-arranging the previous formula:
Q=CV=(10 \mu F)(108 V)=1080 \mu C
