Answer:
true
Explanation:
this the nucleus is located at the centre and contains protons and neutrons
The change in the total energy of the object is zero (0).
The given parameters:
work done by the machine, W = 50 J
mass of the object, m = 10 kg
To find:
the change in the total energy of the object
The change in the total energy of the object is the difference between the objects initial energy due to its position and the work done on the object.
Based on work energy-theory, the work done on the object is equal to the energy of the object.
- The energy of the object = work-done on the object
- The change in total energy = 50 J - 50 J = 0
Thus, the change in the total energy of the object is zero (0).

First thing to note is that we are on week 0, when they start saving:
The equation for Alex is:
y=20x + 125
Know that we are on week 0, and x is our weeks, that makes our equation:
y=20(0) + 125
Which means it's really:
y=125
That means that the first one is E. 125
For the second, it shows our week 0, which is at 100.
That means that the second one is I. 100
Hope this helps!
Answer:
f' = 2 f
Explanation:
The frequency of the pendulum that swings in simple harmonic motion is given by :

Where
l is the length of pendulum
g is the acceleration due to gravity
If the length of the thread is increased by a factor of 4, such that, l' = 4 l, let f' is the new frequency such that,



f' = 2 f
So, the new frequency of the pendulum will become 2 time of initial frequency. Hence, the correct option is (b) "2f"
