Yes it is an ion as it has a positive charge (i.e more protons than electrons, in this case there is no electrons). It's also an ion of an isotope of a hydrogen atom.
Hope this helps :).
We know that;
power=W/t
15000Watts=1800000J/t
t=1800000J/15000Watts
t=120s
Answer:
Decrease in the object's maximum kinetic energy is caused by loss of energy by the system to its immediate surroundings.
Explanation:
None of the options are correct because for an object spring system, maximum kinetic energy is reduced when the system loses energy to the immediate surrounding.
Thus, decrease in the object's maximum kinetic energy is caused by loss of energy by the system to its immediate surroundings.
Velocity units =m/s
Acceleration is the rate of change of velocity
a =timechange in velocity
Therefore SI units of acceleration is ms−1/s=s2m
Answer:
Part a)
Part b)
Part c)
Part d)
Explanation:
Part a)
For hanger we know that it will have tension force upwards while it has downwards its weight so we will have
so we have
Part b)
now for car that is rolling on the floor the net force is given as
Part c)
now we know that the cart and the hanger both are connected to each other
so they must have same acceleration
so we will have
Part d)
now we know that
M = 2.40 kg
m = 0.50 kg
so we will have
