A chain reaction results when a uranium atom is struck by a/an ______________released by a nearby Uranium atom undergoing fissio

finlep [7]

Answer:

Chain reaction is possible by neutron

Explanation:

Nuclear reaction is mainly two types,

⇒ Nuclear Fission : heavy atom split into two light atom.

Ex. Uranium, thorium

⇒ Nuclear fusion : lighter atom combine together

Ex. Hydrogen to helium

In fusion reaction the large amount of energy is produced as compare to fission reaction.

Sun gets brighter by fusion reaction.

In case of uranium fission reaction is possible by colliding neutron.

How long must a simple pendulum be if it is to make exactly one swing per second? (That is, one complete vibration takes exactly

umka2103 [35]

Oscillation is a type of periodic motion which repeats itself to and from about a point which is called mean position. The period of a Pendulum can be described as a ratio between the length and gravity as,

$T = 2\pi \sqrt{\frac{L}{g}}$

Here,

L = length

g = Gravity

If we rearrange to find the length we have that,

$L = \frac{T^2g}{4\pi^2}$

Our period is 2s and the gravity is 9.8m/s^2, then,

$L = \frac{(2)^2(9.8)}{4\pi^2}$

$L = 0.9929m$

The simple required length of the pendulum must be 0.9929m

Check the correctness of formula t=2π √m/k, dimensionally

pantera1 [17]

Hi there! Lets see!

m is mass, and its units are kg
k is the elastic constant measured in newtons per meter (N/m), or kilograms per second squared kg/s²

Therefore:

$\sqrt{\dfrac{m}{k}} =\sqrt{\dfrac{[kg]}{[\dfrac{kg}{s^2}]}} =\sqrt{\dfrac{[kg]}{[kg]}\cdot s^2} = \sqrt{[s]^2} = s$

The period is given in seconds so the formula is dimensionally correct.

Calculate the pressure in SI unit when a force of 100 dyne acts on area of 0.02cm²

Andru [333]

Answer:

500 Pa

Explanation:

Convert given units to SI:

100 dyne = 0.001 N

0.02 cm² = 2×10⁻⁶ m²

Pressure = force / area

P = 0.001 N / (2×10⁻⁶ m²)

P = 500 Pa
