Answer:
Part a)
When spring compressed by 2 cm
H = 1.47 m
Part b)
When spring is compressed by 4 cm
H = 5.94 m
Explanation:
Part a)
As we know that the spring is compressed and released
so here spring potential energy is converted into gravitational potential energy at its maximum height
So we will have
so we have
Part b)
Similarly when spring is compressed by 4 cm
then we have
so we have
A homogenous mixture is a mixture that is consistent throughout. If I pulled a portion of this mixture out twice, like two cup fulls, you wouldn’t be able to notice a difference between the two.
Answer:
Frequency will not change.
Explanation:
As you know, Time period 'T' = 2π x √(L/g)
where,
L= the length of the pendulum
g= acceleration due to gravity
and Frequency 'f' is the reciprocal of period.f=1/T
From above, we can conclude that frequency is not dependent on mass.
It depends upon the acceleration due to gravity 'g' and the length of the pendulum 'L'
So, if a hole in the ball allowed water to slowly leak out, frequency would not change
they work less effectively due to the lack of friction on the road when it is wet
