Putting together two distinct 50 dB sound, do not create a 100 dB sound. Since decibels are logarithm of energy, creating two sounds together only makes the energy increase but the logarithm only goes up by somehow little. So increasing the sound by 10 dB, only makes it 10000 times louder because each 10 dB increase in sound makes the sound 10 times louder.
Twice as loud is an increase of 10Log (2) = 3.01 dB. So, 53,01 dB is twice as loud as 50dB.
Answer:
<em>Total momentum is conserved</em>
Explanation:
<u>Conservation of Momentum
</u>
The momentum is a physical magnitude that measures the product of the object's velocity by its mass. The total momentum of a system is the sum of all its components' individual momentums. The two-bear system starts with a total moment of

When both bears stick together, the total mass is 20 kg, and the new momentum is

We have assumed both bears move to the right after the collision. In this situation, the total momentum is conserved
Explanation:
The given data is as follows.

Voltage = 2.50 V
Hence, calculate the equivalence capacitor as follows.


= 
C = 
Now, we will calculate the charge across each capacitance as follows.
Q = CV
= 
=
=
Thus, we can conclude that
is the charge stored on each given capacitor.
Answer:
E = 420.9 N/C
Explanation:
According to the given condition:

where,
E = Magnitude of Electric Field = ?
v = speed of charge = 230 m/s
B = Magnitude of Magnetic Field = 0.61 T
θ = Angle between speed and magnetic field = 90°
Therefore,

<u>E = 420.9 N/C</u>
Aromatherapy based treatment can offer impermanent help when nasal and sinus tissue drainage blockage and pressure for Mike.
<u>Explanation:</u>
Nasal and sinus tissues provide stuffy nose and pain or pressure in several areas around the face or teeth. There's normally a nasal release that might be yellow, green, or clear. You may likewise have exhaustion, the issue with a feeling of smell or taste, hack, sore throat, terrible breath, migraine, torment when you twist forward, and fever.
For this issue, Mike can utilize Aromatherapy based treatment that can offer some quick help with discomfort on the blocked nose and migraine. During this stage, mike ought to breathe in some restorative or common smell to control his sufferings. Fragrance, for example, Peppermint, Eucalyptus, Tea tree, Oregano, Clary wise, Lavender, Rosemary, and so forth are a great idea to breathe in.
