Answer:
10
Explanation:
The decibel or decibel, is a unit that relates two values of sound pressure, and electrical power. the base unit is the bel, but given the amplitude but for practicality, a submultiple, the decibel, is used. It is a scalar expression .
Zero belios is the reference value used as a base, hence a bel is equivalent to 10 decibels and means that there is a power increase of 10 times over the reference value.
Answer:
The charge is
Explanation:
Given that,
Distance = 2.5 mm
Electric field = 800 NC
Length
We need to calculate the linear charge density
Using formula of linear charge density
Put the value into the formula
We need to calculate the charge
Using formula of charge
Put the value into the formula
Hence, The charge is
5.51 × 10 power 12 newton is answer
Answer:
speed is the rate of change in distance thus it is scalar physical quantity
while velocity is the rate of change in displacement thus it is a vector physical quantity
Explanation:
vector physical quantity: is a quantity that requires both magnitude and direction to identify
scalar quantity: requires only magnitude to identify.
