Convert the following db to decimal a. -12 b. 3 c. 10 d. 0

for -12db

for 3db

for 10db

for 0db

Explanation:

The decibel is a logaritmic value given by:

we use 10 for power values and 20 for other values such voltages or currents.

for -12db

for 3db

for 10db

for 0db

a=d/t

a="triangle"v/t

explanation:

a = acceleration

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
