Answer:
Explanation:
We can use the kinematics equation 
to solve this problem. To find the initial vertical velocity, find the vertical component of the object's initial velocity using basic trigonometry for right triangles:
Now we can substitute values in our kinematics equation:
(acceleration due to gravity) 
- Solving for
As charge flows, the chemical energy of the battery is dissipated as the time of charge flow increases.
Electric power is defined as the rate at which electric energy is dissipated.
The power of the current flowing through the circuit is calculated as follows;
P = IV
P = I x IR
P = I²R
where;
- <em>P is the power dissipated</em>
- <em>I is the current flowing in the circuit</em>
- <em>R is the resistance of the circuit</em>
The electric energy is given as;
E = Pt
E = I²Rt
Thus, we can conclude that as charge flows, the chemical energy of the battery is dissipated as the time of charge flow increases.

Answer:
particle model
Explanation:
A particle model is a simplified version of a motion diagram in which the object in motion is replaced by a series of single points.
Density = mass divided by volume.So, the mass = density times volume.mass = 1.29 x 1 kglinear momentum is defined as mass times velocityso the linear momentum of a cubic metre at 15,000 m per hour would be 1.29 x 15km/h. The units would be kg km/h, which are not the SI units. These are kg m/s. To get to them the speed has to be converted into metres per second.
