Answer:
Explanation:
Gravitational potential energy = mgh where m is mass , g is acceleration due to gravity and h is height .
mg = weight so
Gravitational potential energy = weight x h ( height )
Putting the given values
Gravitational potential energy = 300 x 3
= 900 J .
A change in an object's speed has a(n) _________ effect on its kinetic energy than a change in its mass = <span>A greater effect.</span>
The correct answer for this question is "Two-car length rule." While driving, the principle that you should be used to keep the appropriate distance between your vehicle and the vehicle in front of you is to follow the <span>Two-car length rule. This rule is to be followed for safety.</span>
Explanation:
Let f₁ is the fundamental frequency,
Lower pitch frequency,
Fundamental frequency is, .....(1)
Lower frequency is, ..............(2)
Dividing equation (1) and (2) as :
So, the ratio of linear mass density μ of the string with the higher pitch to that of the string with the lower pitch is 0.00132. Hence, this is the required solution.
