Answer:
The correct option is;
c. 22.6
Explanation:
The given parameters are;
The hypotenuse of the vector = 32
The angle of the vector = 45°
Therefore, the vector component in the y-axis is given as follows;

Substituting the values from the question gives;

The vector component in the y-axis,
, is approximately 22.6.
To solve this problem it is necessary to apply the concepts related to Kinetic Energy, specifically, since it is a body with angular movement, the kinetic rotational energy. Recall that kinetic energy is defined as the work necessary to accelerate a body of a given mass from rest to the indicated speed.
Mathematically it can be expressed as,

Where
I = Moment of Inertia
Angular velocity
Our values are given as

A revolution is made every 4.4 seconds.


If the angular velocity is equivalent to the displacement over the time it takes to perform it then


Replacing at our previous equation we have,



Therefore the kinetic energy is equal to 
In order for a fusion reactor to function well, one of the important conditions to be met is a high temperature at 108 million Kelvin. This is six times hotter than the temperature of the sun's core. At this temperature, the element hydrogen's state is a plasma, not a gas, where the atoms are stripped of electrons and thus can move freely. This is an ideal condition to enable the reactor to function where it enables the hydrogen atoms to gather enough energy for the reaction which will occur in the later stages of the process. <span />
Answer:
Kinetic energy = 127.89 Joules
Explanation:
Kinetic energy is calculated using the following rule:
KE = (1/2)*v* v^2
Where:
m is the mass = 145 g = 0.145 kg
v is the velocity = 42 m/sec
Substitute in the above equation to get the kinetic energy as follows:
KE = (0.5)(0.145)(42)^2
Kinetic energy = 127.89 Joules
