Answer:
Because unlike inert gas Noble gas sometimes indergo reaction
Explanation:
Inert gas as the name suggest means it can not undergoing reaction at most conditions.But as a science progresses it was found that some group 8 elements under special conditions of temperature and pressure can under go reaction this discovery led to why inert gas is not commonly used
The object is no longer stationary when it is applied by push or pull.
<h3><u>Explanation: </u></h3>
The stationary position of an object means it is at one spot and remains there until an external stimulus is added.
To move an object from it's stationary position, an external stimulus, a push or a pull is applied to it. This push or pull is called Force. It is used for the following:
a) Moving an object
b) Bringing a moving object to a stop
c) Changing the shape of an object
The effect of force on a stationary object is determined on the basis of it's two types: Balanced forces and Unbalanced forces
Balanced forces would either keep a stationary object in the same state or a moving object continues to move in the same direction and same speed as it did earlier. These forces are applied on an object from opposite directions and in equal amount.Unbalanced forces are two forces applied on an object. The forces are unequal in amount. They cause a change in the speed and direction of a moving object.
Answer:
0.84 m
Explanation:
Given in the y direction:
Δy = 0.60 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
0.60 m = (0 m/s) t + ½ (9.8 m/s²) t²
t = 0.35 s
Given in the x direction:
v₀ = 2.4 m/s
a = 0 m/s²
t = 0.35 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.4 m/s) (0.35 s) + ½ (0 m/s²) (0.35 s)²
Δx = 0.84 m
Answer:
Explanation:
Suppose mass of block 1 is and of block 2
For original system
natural frequency of oscillation is given by
Maximum kinetic Energy is equal to total Energy of the system
where k=spring constant
A=maximum amplitude
Now Block B is Placed at block 1 at maximum amplitude such that A=A'
i.e. new amplitude=old amplitude
Maximum kinetic energy of combined system is
as the total energy is independent of mass therefore maximum kinetic energy will remain same
