Answer:
The electric force will be 0 N
Explanation:
From the question we are told that
The magnitude of the charge is 
Generally from Coulombs law the electric force between two charges is mathematically represented as
Here r is the distance of separation between that two charges.
Now from the question we are told that the charge is far away from any other charge hence we can say that the distance between the charge and any other charge is 
So
=> 
Hence the electric force will be 0 N
To solve this problem it is necessary to apply the concepts related to the kinematic equations of motion for which the height of a particle is defined as a function of gravity as,
Where,
h = Height
g = Gravity constant
v = Velocity
There is not change in the horizontal component, therefore there is only the component horizontal given (18m/s) and the vertical component:
Applying the vector theory to find the magnitude of a vector we have to
The speed at which the ball was thrown was 25.38
In general? Well one example could be that if you owned an ice rink and somehow the ice had friction, you wouldn't be able to slide around on it any more to skate because the motion between one solid (your feet) and another (the ice) would increase. An effect of friction is heat, but my mixtape already fire so whats that even matter tbh.

Answer:
<em>P = 66.67 W</em>
Explanation:
<u>Joule Heating</u>
It's the process by which the electric current passing through a conductor produces heat.
Also known as Joule's first law or the Joule–Lenz law, states that the power of heating generated by an electrical conductor (P) is proportional to the product of its resistance (R) and the square of the current (I).
It can be described by the equation that follows:
Also, we can calculate the voltage V with the formula of Ohm's law:
Combining both equations, power can be related to the voltage:
Given the power and the voltage, the resistance can be calculated by solving for R:
There are two bulbs marked P=200W V=250V and P=100 W V=250.
The first bulb has a resistance of:
The first bulb has a resistance of:
When connected in series, the total resistance is
The total power consumed when connecting them to a V=250 V supply is:
P = 66.67 W
