Answer:
The linear momentum is given by the following equation:
(1)
Where is the mass and the velocity.
On the other hand, the kinetic energy is given by:
(2)
Which is the same as:
Now, if we double the kinetic energy, equation (2) changes to:
(3)
So, if we want to obtain the kinetic energy as shown in (3), the only option that works is increasing momentum by a factor of or :
Applying this in (2):
>>>As we can see, this equation is the same as equation (3)
Therefore, the correct answer is B
In physics, a gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body. Thus, a gravitational field is used to explain gravitational phenomena, and is measured in newtons per kilogram (N/kg).
Answer:
t = 444.125 sec
Explanation:
Given data:
V = 24 volt
I = 0.1 ampere
mass of water mw = 51 gm
cr = 4.18 J/gm degree K^-1
mass of resistor = 8 gm
cr = 3.7 J/gm degree K^-1
we know that power is given as
Power P = VI
But P =E/t
so equating both side we have
solving for t
t = 444.125 sec
Answer:
850N
Explanation:
The step by step is in the attachment.
The particles themselves do not change in size. When changing state the distance between the particles is what changes due to overcoming the intermolecular forces between the particles.
