Answer:
0.1364 $/kWh
Explanation:
Annual expenditure of the family on electricity = $1500
Total energy consumed during the year = 11000 kWh
Kilowatt hour is the unit of energy which is given by the product of the energy in kW and the number of hours that energy has been used.
Unit price of energy = Annual expenditure / Total energy consumed during the year
∴ Unit price of energy is 0.1364 $/kWh
Answer:
43°
Explanation:
Sin tita m= mlambda/d
Sin 20°= lambda/d
Sin tita 2= 2(lambda/d)
Sin tita 2= 2 sin 20
Sin tita 2= 0. 684
Tita 2= sin-1(0. 684)
Tita 2= 43°
Thus, the angle of the second order maximum is 43°
Answer:
a) Angular speed(w) = 2.02rad/sec
b) 73J ( It is Inelastic Collision)
Explanation:
Given:
Mass=45kg
Length on each side = 1.5m side which is hangs vertically from a frictionless pivot at the center of its upper edge.
We need to calculate
(a) What is the angular speed and
(b) To know why the angular momentum conserved but not the linear momentum
