Answer:
Associations Clusters
Explanation:
There is three basic type of clusters, globular clusters, open clusters, associations clusters. Associations cluster consist of younger stars that is younger than globular and open clusters stars.
Answer:
Required energy = 4758 J
Explanation:
Specific heat capacity of a material is the amount of energy required to raise the temperature of one kilogram (kg) of that material through one degree Celsius (°C).
Given data :
Specific heat capacity = c = 2440 J/kg.°C
Mass = m = 150 g = 0.15 kg
Initial temperature = 22°C
Final temperature = 35°C
Change in Temperature = ΔT = 13°C
Energy = E = ?
Using the following formula and substituting the values, we get:
E = m × c × ΔT
E = 0.15 × 2440 × 13
E = 4758 J
Here, Fe = Fg
q.E = m.g
We have: E = 360 V
m = 5.4 × 10⁻⁵
g = 9.8 m/s² [ constant value for earth system ]
Substitute their values into the expression:
q (360) = 5.4 × 10⁻⁵ × 9.8
q = 52.92 × 10⁻⁵ / 360
q = -1.47 × 10⁻⁶ [ negative sign represents the nature of charge ]
So, Your Final answer would be 1.47 × 10⁻⁶
Hope this helps!
Answer:
Generation ----transmission---distribution
Explanation:
Electricity is generated from the generating station which could be (thermal, hydro, nuclear, coal etc) ,it is generated at a low voltage and is being step up to a higher voltage with the aid of transformers. This transformers step up and step down voltages from one level to another. At the transmission end they ensure the voltage get to the distribution end .the distribution end ensures the voltages are being supplied to nearby homes. The rated voltage for homes is 230v in some countries or 110V in other countries.
Electricity is useful and powerful for modern society because majority of the equipments in use today depends on electricity for use.which makes it very important.
