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
The jogger's average speed 1.03 m/s
<h3>
The Speed and the Velocity of a Particle in a Circle</h3>
The speed of a particle is a circle will always be constant while the velocity will not. That is, velocity varies.
Given that a jogger jogs around a circular track with a diameter of 275 m in 14.0 minutes. First convert the minutes to seconds
Given parameters are;
- Time t = 14 minutes = 14 x 60s = 840 s
Speed V = 2πr ÷ t
V = ( 2 × π × 137.5 ) ÷ 840
V = 863.9 / 840
V = 1.028 m/s
Therefore, the jogger's average speed 1.03 m/s approximately

Answer:
acceleration = 0.8181 m/s²
Explanation:
given data
mass = 1.1 kg
apart d = 1 m
charge q = 10 μC
to find out
What is the initial acceleration
solution
we know that acceleration is
acceleration = 
.................1
here force = 
here q1 q2 is charge and r is distance and Coulomb constant k = 9 × 
Nm²/C²
force = 
force = 0.9 N
so from equation 1
acceleration = 
acceleration = 0.8181 m/s²
20 degrees F! 0 degrees C is equivalent to 32 degrees F, so 20 degrees F is colder.
