Able to be hammered or pressed permanently out of shape without breaking or cracking.
Answer:
Explanation:
The spring is stretched by .5 m and then released that means its amplitude of oscillation A is 0.5 m .
A = 0.5 m
After the release at one extreme point , the mass comes to rest again at another extreme point after half the time period ie
T / 2 = .3 s
T = 0.6 s
Angular velocity
ω = 
ω = 
ω = 10.45
Maximum velocity = ω A
ω and A are angular velocity and amplitude of oscillation.
Maximum velocity = 10.45 x .5
= 5.23 m /s
Answer:
Z
Explanation:
The purple and yellow rays from the same point on the object are shown converging at point Z, where the image will be.
Darwin's atomic theory which states that atoms do not emit or absorb energy so far as they remain in allowable orbits or ground states.It also states that a spectra is produced when an electron moves to a lower energy level thereby releasing energy.
Answer:
Energy
Explanation:
The unit is
.
We can see the formula of kinetic energy is

Where
is the mass and
is the velocity of the object.
Which means its unit would be kg times square of meter per second, that is
. Which is often referred as Joule.
Also, when look at the formula of work done by an object.

Where
is the force and
is the distance traveled by the object due to force
.
We an see that its unit is kg meter per second squared times meter. That is equivalent to
. This is also a type of energy.
So, the unit
is the unit of energy.
