The cloud of interstellar dust and gas that forms a star is known as a nebula. With an average surface temperature of about 737K, venus is the hottest planet. Hope this helps, and sorry your question didn't get answered in time.
The law states that external forces cause objects to accelerate, and the amount of acceleration is directly proportional to the net force and inversely proportional to the mass of the object.

Answer:
Part a)
T = 3.96 s
Part b)
T = 1.98 s
Part c)
T = 2.8 s
Explanation:
As we know that time period of spring block system is given as

T = 2.8 s
Part a)
If the mass of the block attached is doubled
then we will have



Part b)
If the spring constant is doubled
then we have



Part c)
If the amplitude is halved but mass and spring constant will remain the same
so here we know that time period does not depends on Amplitude
so we will have

T = 2.8 s
Answer:

Explanation:
As we know that the force per unit length of two parallel current carrying wires is given as

here we know that


d = 2.2 cm
now from above equation we have
