Dividing x^3 - 3x^2 - 4x + 12 by x + 2 gives
x^2 -5x + 6
= (x - 3)(x - 2)
so remaining factors are x - 3 and x - 2 answer
Kepler’s
third law formula: T^2=4pi^2*r^3/(GM)
We’re trying to find M, so:
M=4pi^2*r^3/(G*T^2)
M=4pi^2*(1.496
× 10^11 m)^3/((6.674× 10^-11N*m^2/kg^2)*(365.26days)^2)
M=1.48× 10^40(m^3)/((N*m^2/kg^2)*days^2))
Let’s work
with the units:
(m^3)/((N*m^2/kg^2)*days^2))=
=(m^3*kg^2)/(N*m^2*days^2)
=(m*kg^2)/(N*days^2)
=(m*kg^2)/((kg*m/s^2)*days^2)
=(kg)/(days^2/s^2)
=(kg*s^2)/(days^2)
So:
M=1.48× 10^40(kg*s^2)/(days^2)
Now we need to convert days to seconds in order to cancel
them:
1 day=24 hours=24*60minutes=24*60*60s=86400s
M=1.48× 10^40(kg*s^2)/((86400s)^2)
M=1.48× 10^40(kg*s^2)/(
86400^2*s^2)
M=1.48× 10^40kg/86400^2
M=1.98x10^30kg
The
closest answer is 1.99
× 10^30
(it may vary
a little with rounding – the difference is less than 1%)
Answer:
Explanation:
Total momentum of the system before the collision
.5 x 3 - 1.5 x 1.5 = -0.75 kg m/s towards the left
If v be the velocity of the stuck pucks
momentum after the collision = 2 v
Applying conservation of momentum
2 v = - .75
v = - .375 m /s
Let after the collision v be the velocity of .5 kg puck
total momentum after the collision
.5 v + 1.5 x .231 = .5v +.3465
Applying conservation of momentum law
.5 v +.3465 = - .75
v = - 2.193 m/s
2 ) To verify whether the collision is elastic or not , we verify whether the kinetic energy is conserved or not.
Kinetic energy before the collision
= 2.25 + 1.6875
=3.9375 J
kinetic energy after the collision
= .04 + 1.2 =1.24 J
So kinetic energy is not conserved . Hence collision is not elastic.
3 ) Change in the momentum of .5 kg
1.5 - (-1.0965 )
= 2.5965
Average force applied = change in momentum / time
= 2.5965 / 25 x 10⁻³
= 103.86 N
Answer:
Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal.
Explanation:
From ideal gas law, PV=nRT
where P is the pressure, V is the volume of the container, n is number of moles, R is the gas constant and T is the temperature.
Hence, 
T= 110.65 k

<h3>What is a kinetic energy? </h3>
The energy an object has as a result of motion is known as kinetic energy.
A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed. Kinetic energy is the type of energy that is transferred and is dependent on the mass and speed attained.
Kinetic energy can be converted into other types of energy and transported between objects. A flying squirrel may run into a chipmunk that is standing still, for instance. Some of the squirrel's initial kinetic energy may have been transferred to the chipmunk or changed into another kind of energy after the collision.
