ASHA 777 [7]

Answer:

0.011 m.

Explanation:

Energy stored in the spring = Energy of the projectile.

1/2ke² = mgh ................ Equation 1

Where k = spring constant, e = extension or compression, m = mass of the projectile, g = acceleration due to gravity, h = height.

make e the subject of the equation

e = √(2mgh/k)............................. Equation 2

Given: k = 12 N/cm = 1200 N/m, m = 15 g = 0.015 kg, h = 5.0 m

Constant: g = 9.8 m/s²

Substitute into equation 2

e = √(2×0.015×5/1200)

e = √(0.15/1200)

e = √(0.000125)

e = 0.011 m.

The power is inversely proportional with time
trapecia [35]

Answer:

True

Explanation:

Given that Power whose unit is Watt equates to one joule of work per second. It implies that Power is directly proportional to the work done and inversely proportional to the time to do the work.

Therefore, in this case, the right answer to the question is that it is TRUE that the power is inversely proportional with time

Why do we say that a spring is elastic? Why do we say that a spring is elastic? It does not obey Hooke's law. When deformed, it
borishaifa [10]

Answer:

When deformed, it returns to its original shape

Explanation:

  • A spring is elastic.  
  • Elasticity is the property of a material to regain its shape after having been deformed.
  • It means that when the force is doubled, the amount of deformation in it gets doubled.
  • Hence, the correct option is (b) " When deformed, it returns to its original shape".
