Answer;
= 0.018 mm
Explanation;
Mass = 12 ounces
1 ounce = 28.4 g
thus mass in g = 12 × 28.4 = 340.8 g
Volume = mass/density
= 340.8 g /2.70 g/cm³
= 126 cm³
The thickness from volume and area;
thickness = volume/ area
Area = 75 square ft
1 Square ft = 929.03 square centimeter
Thickness = 126 cm³/ (75 × 929.03)
= 0.001808 cm
but, 1 cm = 10 mm
Therefore; 0.001808 ×10 = 0.01808 mm
= 0.018 mm ( 3 decimal places)
The total distance traveled in km is 86.4 km
From the question,
We are to determine the total distance traveled in km.
First, we will determine the distance traveled in m.
Distance traveled can be calculated using the formula
Distance = Speed × Tim
From the given information,
Speed = 30.0 m/s
Time = 0.8 hr = 0.8 × 60 × 60 s
Time = 2880 s
Putting the parameters into the formula, we get
Distance = 30.0 × 2880
Distance = 86400 m
Now, we will convert from meters (m) to kilometers (km)
NOTE: 1000 m = 1km
If 1000 m = 1km
Then, converting 86400 m into km = 86400/1000 = 86.4 km
Hence, the total distance traveled in km is 86.4 km

Answer:
Kinetic energy and potential energy.
The term 'mechanical energy' refers to the sum of the kinetic energy and the gravitational potential energy of an object,
The electric potential energy of the charge will be =3.5*10^8 J
<h3 /><h3>What is Electric potential energy?</h3>
Electric potential energy is the energy that is needed to move a charge against an electric field.
F=Force experienced by the charge = 3.6*10^-4 N
q1 = magnitude of charge producing the electric field
q2 = magnitude of charge experiencing the electric force
r1 = distance between the two charges
Electric force experienced by the charge is given using coulomb's law as
Electric potential energy of the charge can be given as
Thus Electric potential energy of the charge can be given as
