The electric field between two plates is 40 V/m.
To find the electric field between two plates, the values are given are,
distance = 3 cm
Voltage v = 120 v
<h3>What is electric field between two plates?</h3>
The electric field between plates is the area where the charges between two plates, influences can be seen. For example, if a charged particle is placed near any charged plate, the plate exerts an electric force to attract or repel the charged particle.
Formula is given as,
E = V / d (v/m)
Substituting the given values,
= 120 /3
=40 v/m
Hence, the answer is 40 v/m.

Answer:
maximum speed = 1.55 m/s
speed is 0.775 m/s
Explanation:
given data
mass m = 0.25 kg
spring constant k = 15 N/m
amplitude A = 20 cm = 0.2 m
to find out
maximum speed and speed at the 1/2 amplitude
solution
we know formula for maximum speed that is
maximum speed = amplitude ×√(k/mass)
put all value
maximum speed = 0.2 ×√(15/0.25)
maximum speed = 1.55 m/s
and
at the 1/2 amplitude
we apply here conservation of energy that is
1/2 × m×v² = 1/2 × k×x²
here we know x = A/2 that is 20 /2 = 10 cm = 0.1 m
so
0.25 v² = 15 × 0.1²
v² = 0.600625
v = 0.775
so speed is 0.775 m/s
Well water would prob be your best bet, you could extract the salt first and then use a magnet to seperate the iron filing from the sand
We can get water from the sweat and exhaled breath of the people present in the space station.
<h3>How would you get water?</h3>
We can get water from the sweat and exhaled breath. The water we drink is recycled from the sweat and exhaled breath of the people present in the space station which was collected through condensation on the Space Station's walls.
So we can conclude we can get water from the sweat and exhaled breath of the people present in the space station.

As per conditions described here we know that all force arrow are not of equal length
So all forces are not same in magnitude
Here applied force on right direction is more in magnitude then the friction force on left
So it will have net unbalanced force towards right due to which it will move towards right direction or in the direction of net unbalanced force
While in the upward and downward direction the forces are balanced and hence the box will not move in that direction
So normal force will be balanced by gravitational force
So here answer will be
The forces acting on the box are <u>UNBALANCED</u> .
The box will move to the <u>RIGHT</u> .
