Answer:
the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s
Explanation:
Answer:
Explanation:
firstly we have to find the frequency and then the angular frequency.
The frequency will be:
The angular frequency is:
ω
ω
ω
Now we can apply simple pendulum relationship
ω
make g the subject of the formula
Nah cause it would sink m8 so no its false
Answer:
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W.
The internal energy of ideal gas is U = cV The change in internal energy for ideal gas is therefore ∆U = cV ∆T, where cV is specific heat (at constant volume), and ∆T is change in tem- perature.

ihopeithelps
Part A: a->positive when velocity is increasing a->negative when velocity is decreasing a->zero when velocity is constant
