How can a small spark start a huge explosion? using electric forces and molecules

Physics
1 answer:
OLga [1]3 years ago
4 0

Answer:

Small sparks can lead to huge explosion if they are left unattended.

Explanation:

Small sparks are not harmful but if these sparks happen near some hazardous material or object then it could lead to heavy explosion. If there is some chemical substance near the spark or there are magnetic lines which can explode the spark then these minor sparks could result in heavy disastrous explosion.

A pendulum is timed, first for 20 swings and then for
wlad13 [49]

w =  \frac{t(50) - t(20)}{50 - 20}  =  \frac{43.2 - 17.4}{50 - 20}

w =  \frac{25.8}{30}  = 0.86 \: sec \: per \: swing

The results may differ due to resistive forces that may be affecting the system by decelerating it or any other external forces that might accelerate it a bit.Or the timing could be a little inaccurate.

A block of wood weighs 160 N and has a specific gravity of 0.60. To sink it in fresh water requires an additional downward force
AysviL [449]

Answer:

Your answer is: D) 110N

Hope this helped : )

Explanation:

In order for the wood to sink, it's specific gravity must equal 1 (or greater).

Specific gravity = .6 kg/m^3= Mass/volume

F (Newtons or kg x m/s^2) = Mass*9.8m/s^2.  

Therefore, Mass = 160 N / 9.8 m/s^2= 16.32 kg

Volume = Mass/Specific Gravity = 16.32kg/.6 kg/m^3 = 27.2 m^3

Desired Specific gravity = 1 = (Mass + additional force/9.8m/s^2)/Volume = (16.32 kg +X / 9.8m/s^2)/27.2m^3

Solving for the additional force: X = 106.66...N

The answer is D, 110 N will be required to sink the block of wood.
