Answer:
Y = 31750 Pa = 31.75 KPa (For 24.5 N force)
Y = 312500 Pa = 312.5 KPa (For 250 N force)
Explanation:
Since the elongation is constant. Therefore, the strain will remain the same in both cases:
<u>FOR A FORCE OF 25.4 N</u>:
Now, for Young's Modulus:
<u>Y = 31750 Pa = 31.75 KPa</u>
<u></u>
<u>FOR A FORCE OF 520 N</u>:
Now, for Young's Modulus:
<u>Y = 312500 Pa = 312.5 KPa</u>
P=m/v
p=(292.2-130.2)/200
p=0.8100g/ml
Speed=frequency*wavelength
Given
frequency=1200\ Hz
and
wavelength=0.300\ m
we get:
speed=1200\ Hz*0.300\ m=360\ m/s
The kinetic energy of a 204 kg motorcycle moves with a velocity of 6 m/s is 3672 joules (3672=0.5*204*6^2). This problem can be solved using the formula of an object's kinetic energy which is the energy of a motion. The formula of an object's kinetic energy is stated as KE = 0.5*m*v^2 where KE is the objects' kinetic energy amount, m is the object's mass, and v is the object's velocity<span>.</span>
Momentum is proportional to mass.
This is the more the mass the higher the momentum.
Linear momentum, p = mass * velocity, so you can see the direct relation: at constant velocity if the mass is duplicted the linear momentum is duplicated.
Angular momentum, L = moment of inertia * angular velocity.
So the moment of inertia is to the angular momentum as mass is to the llinear momentum.
Moment of inertia takes into account how the mass is distribuited around the rotation axis.
