The frictional force is 39.4 N
Explanation:
We can solve this problem by applying Newton's 2nd law of motion: in fact, the net force acting on the block is equal to the product between its mass and its acceleration. So we can write
where
is the net force
m is the mass
a is the acceleration
Here we know that the box is moving with constant velocity, so its acceleration is zero:
This means that the net force is also zero:
The net force on the block is given by the applied force, forward, and the frictional force, backward:
where
is the applied force
is the frictional force
Therefore, solving for ,

Answer:
(a) The resistance R of the inductor is 2480.62 Ω
(b) The inductance L of the inductor is 1.67 H
Explanation:
Given;
emf of the battery, V = 16.0 V
current at 0.940 ms = 4.86 mA
after a long time, the current becomes 6.45 mA = maximum current
Part (a) The resistance R of the inductor
Part (b) the inductance L of the inductor
where;
L is the inductance
R is the resistance of the inductor
t is time
Therefore, the inductance is 1.67 H

Answer:
a bowling ball placed on the top shelf of a closet.
Explanation:
Potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
Mathematically,
Potential energy, PE = M × g × h
This answer is false. A visual artist is defined as someone involved in the arts of painting, sculpting, photography, etc, as opposed to music, drama, and literature. A visual artist is in the form of making somthing more visable. So, a graphic designer is a visual artist.
