The period of the block's mass is changed by a factor of √2 when the mass of the block was doubled.
The time period T of the block with mass M attached to a spring of spring constant K is given by,
T = 2π(√M/K).
Let us say that, when we increased the mass to 2M, the time periods of the block became T', the spring constant is not changed, so, we can write,
T' = 2π(√2M/K)
Putting T = 2π(√M/K) above,
T' =√2T
So, here we can see, if the mass is doubled from it's initial value. The time period of the mass will be changed by a factor of √2.

The answer to this question is "Buffeting". This is an unusual strong wind condition that resulted in the loss of vehicle control. This condition occurs in roads and bridges, across and along mountains that affected vehicles control. The drivers must be alert and put their full attention to overcome this condition.
        
             
        
        
        
Answer:
the magnetic field can be used to make electricity 
Explanation:
Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy

Explanation:
 = temperature of the surface of sun = 5800 K
 = temperature of the surface of sun = 5800 K
 = Radius of the Sun = 7 x 10⁸ m
 = Radius of the Sun = 7 x 10⁸ m 
 = Surface area of the Sun
 = Surface area of the Sun
Surface area of the sun is given as 

 = Emissivity = 1
 = Emissivity = 1
 = Stefan's constant = 5.67 x 10⁻⁸ Wm⁻²K⁻⁴
 = Stefan's constant = 5.67 x 10⁻⁸ Wm⁻²K⁻⁴
Using Stefan's law, Power output of the sun is given as
