Power consumed by the refrigerator is given as

Now if refrigerator is used 10 h a day then total usage of refrigerator for 1 month will be given as

now the total energy consumed in one month is given as




now it is given that cost of one kWh is $0.20
then total cost of one month is given as


Answer:
a) Time = 2.67 s
b) Height = 35.0 m
Explanation:
a) The time of flight can be found using the following equation:
(1)
Where:
: is the final position in the horizontal direction = 80 m
: is the initial position in the horizontal direction = 0
: is the initial velocity in the horizontal direction = 30 m/s
a: is the acceleration in the horizontal direction = 0 (the stone is only accelerated by gravity)
t: is the time =?
By entering the above values into equation (1) and solving for "t", we can find the time of flight of the stone:

b) The height of the hill is given by:
Where:
: is the final position in the vertical direction = 0
: is the initial position in the vertical direction =?
: is the initial velocity in the vertical direction =0 (the stone is thrown horizontally)
g: is the acceleration due to gravity = 9.81 m/s²
Hence, the height of the hill is:

Explanation:
It's actually simple. Each of those elements have a meaning of a material. So, in this case it's Lead(ii) Chloride + Silver Nitrate = Lead(ii) Nitrate + Silver ChlorideLead(ii).
Answer:
2.5 kg
Explanation:
We can solve the problem by using Newton's second law:

where
F is the net force acting on the train
m is the mass of the train
a is the acceleration
For the toy train in the problem,
F = 3.0 N
a = 1.2 m/s^2
So we can solve the formula for m, to find the mass of the train:
