Fluid friction is the kind of friction between the skydiver and the air.
<h3><u>Explanation:</u></h3>
Objects moving through fluid experience fluid friction or drag. A skydiver diving in air is an example of fluid friction since air as a medium is fluid and thus air molecules resists the falling motion of a body. Weight of the object due to gravity decides the acceleration of a skydiver when in flight and the resisting frictional force (drag), opposes it.
So, a resultant force acts and his velocity increases proportionally at first and then becomes a constant terminal value. The extent of fluid friction is dependent on the size of body as well as its speed. Larger the size more is the friction; higher the speed more is the friction.
136 multiply 34x4 and it will equal 136
As we know that electric field at a point due to a point charge is given by
![E = \frac{kq}{r^2}](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7Bkq%7D%7Br%5E2%7D)
here we can see that electric field is directly depends on the magnitude of charge
so if we change the magnitude of charge by some factor then electric field will change by same factor
so here as given that charge is doubled
then electric field due to that charge at the same point also get doubled
Since this is definitely a RIGHT triangle (the little square in the corner),
the hypotenuse is 15, 'h' is the side opposite the 38-degree angle, and
sin(38°) = h / 15
Multiply each side by 15: h = 15 sin(38°)
= 15 (0.616)
h = 9.235
Answer:
4.2 A
Explanation:
V=IR
V= voltage
I= Current
R= resistance
so you will find the resistance in the circuit so
R= V/I
R=2V/0.70A
R=2.857 ohms ( TO THE NEAREST THOUSANDTH)
then you will find the current of the 12V battery using the resistance in the circuit
I=V/R
I=12/2.857
I=4.2A (TO THE NEAREST TENTH)
