The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

Answer:
There will be 1800 W power consumption in heater
Explanation:
We have given current flowing in the heater I = 15 A 
Voltage on which heater is operating V = 120 volt 
We have to find the power consumption in the heater 
We know that power consumption is given by P = VI 
So power consumption in heater = 120 × 15 = 1800 W
So there will be 1800 W power consumption in heater

Explanation:
 
Show that the motion of a mass attached to the end of a spring is SHM
 
 
 Consider a mass "m" attached to the end of an elastic spring. The other end of the spring is fixed
 at the a firm support as shown in figure "a". The whole system is placed on a smooth horizontal surface.
 If we displace the mass 'm' from its mean position 'O' to point "a" by applying an external force, it is displaced by '+x' to its right, there will be elastic restring force on the mass equal to F in the left side which is applied by the spring.
 According to "Hook's Law
F = - Kx ---- (1)
 Negative sign indicates that the elastic restoring force is opposite to the displacement.
 Where K= Spring Constant
 If we release mass 'm' at point 'a', it moves forward to ' O'. At point ' O' it will not stop but moves forward towards point "b" due to inertia and covers the same displacement -x. At point 'b' once again elastic restoring force 'F' acts upon it but now in the right side. In this way it continues its motion
 from a to b and then b to a.
 According to Newton's 2nd law of motion, force 'F' produces acceleration 'a' in the body which is given by
F = ma ---- (2)
 Comparing equation (1) & (2)
ma = -kx
 Here k/m is constant term, therefore ,
a = - (Constant)x
or
a a -x
 This relation indicates that the acceleration of body attached to the end elastic spring is directly proportional to its displacement. Therefore its motion is Simple Harmonic Motion.
