Answer:
7. 0 = 500 kilotons of TNT = 2.0 x 10^15 joules
8.0 = 15 million tons of TNT = 6.3 x 10^16 joules
9.0 = 500 million tons of TNT = 2.0 x 10^18 joules
atomic bomb dropped on Hiroshima had a equivalent of 15 kilotons TNT
Explanation:
formula :
log E = 5.24 + 1.5M
M is richter scale magnitude
if 8.3 = richter scale magnitude
log E = 11.8 + 1.5M Write the formula.
log E = 11.8 + 1.5(8.3) Replace M with 8.3.
log E = 24.25 Simplify
10^log E = 10^24.25
E = 10^24.25
E ≈ 1.78 x 10^24 ergs ≈ 1.78 × 1017 joules

A) prove that the electric field of the point charge is radial by comparing your values in column 5 (position angle) and in column 7 (electric field angle). Explain.
Electric field simply means an electric property that is associated with each point in a space when there is a charge present.
What is an electric field?Your information is incomplete. Therefore, an overview of an electric field will be given.
An electric field simply means the physical field that surrounds particles that are electrically charged.
It should be noted that the electric field exerts force on the other charged particles that are in the field by either attracting or repelling them.
In conclusion, the SI unit of an electric field is volts per meter. This is also equivalent to Newton's per coulomb.

The average speed of an object which moves 10 km in 30 minutes is
Explanation:
An object which moves 10 km in 30 minutes .
we have to find the average speed of the object .
Changing unit of time into hour
Time = 30/60 hour
Time = 1/2 hour
Time = 0.5 hour
Now let's calculate the average speed
[tex] \rm\bf \: Average \: speed \: = \frac{Total \: distance}{Total \: time \: } [/tex]
Put the value we get
[tex] \dashrightarrow \sf \: Average \: speed \: = \frac{10}{0.5} \\ \\ \dashrightarrow \sf \: Average \: speed \: = \frac{100}{5} \\ \\ \dashrightarrow \sf \: Average \: speed \: = \cancel \frac{100}{5} \\ \\ \dashrightarrow \sf \: Average \: speed \: =20km {hr}^{ - 1} [/tex]
So, the average speed is 20km/hr

A particle with a charge of +7.4 C is separated from another charged particle with a charge of
-3.6 uC by a distance of 1.4 m. Find the direction and the magnitude of electrostatic force
between the particles.
Explanation:
9 × 10^-3 × 13.59 = 0.122 N
The given question is incorrect I think the question you asking is:
A particle with a charge of +7.4μC is separated from another charged particle with a charge of -3.6μC by a distance of 1.4 m. Find the direction and the magnitude of the electrostatic force between the particles.
The electrostatic force between the particles is 0.122N. The direction of the force is from the negatively charged particle to the positively charged particle.
What is electrostatic force?The electrostatic force is the force of attraction or repulsion between two charged particles due to their electric charges. It is a fundamental force in nature and is described by Coulomb's law, which states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Here in the Question,
Given Data:
Charge of particle 1 (q1) = +7.4 μC = 7.4 × 10^-6 C
Charge of particle 2 (q2) = -3.6 μC = -3.6 × 10^-6 C
Distance between the two particles (r) = 1.4 m
Coulomb's constant (k) = 8.99 × 10^9 N·m^2/C^2
Using Coulomb's law:
Electrostatic force (F) = (k * |q1| * |q2|) / r^2
where |q1| and |q2| are the magnitudes of the charges.
Substituting the values, we get:
F = (8.99 × 10^9 N·m^2/C^2) * (7.4 × 10^-6 C) * (3.6 × 10^-6 C) / (1.4 m)^2
F = 0.12219≈0.122
Therefore, The electrostatic force between the particles is 0.122N. Since one of the charges is negative, the force will be attractive, pulling the particles toward each other.

Explanation:
suppose that you have 2 boxes. one has a bottom of 0.25 m x 0.20 m and a mass of 55.5 kg. the other box has a bottom of 0.20 m x 0.40 m and a mass of 65.5 kg. find the pressure each box exerts on the ground and indicate which is the most
Answer:
Approximately [tex]1.1 \times 10^{4}\; {\rm Pa}[/tex] and [tex]8.0 \times 10^{3}\; {\rm Pa}[/tex], respectively (assuming that [tex]g = 9.81\; {\rm N \cdot kg^{-1}}[/tex].)
The [tex]55.5\; {\rm kg}[/tex] box exerts more pressure than the [tex]65.5\; {\rm kg}[/tex] box.
Explanation:
Let [tex]m[/tex] denote the mass of the [tex]55.5\; {\rm kg}[/tex] box.
The weight of that box would be: [tex]W = m\, g[/tex].
The normal force [tex]N[/tex] that this box exerts on the ground would be the same as its weight: [tex]N = W = m\, g[/tex].
If the contact area between the box and the ground is [tex]A[/tex], the pressure [tex]P[/tex] that this box exerts on the ground would be [tex]N / A[/tex]. That is:
[tex]\displaystyle P = \frac{N}{A}= \frac{m\, g}{A}[/tex].
The contact area between the ground and this [tex]55.5\; {\rm kg}[/tex] box is [tex]A = 0.25\; {\rm m} \times 0.20\; {\rm m}[/tex]. Substitute in these values and evaluate to find the pressure:
[tex]\begin{aligned} P &= \frac{N}{A} \\ &= \frac{m\, g}{A} \\ &= \frac{55.5\; {\rm kg} \times 9.81\; {\rm N \cdot kg^{-1}}}{0.25\; {\rm m} \times 0.20\; {\rm m}} \\ & \approx 1.1 \times 10^{4}\; {\rm Pa}\end{aligned}[/tex].
Similarly, for the [tex]65.5\; {\rm kg}[/tex] box:
[tex]\begin{aligned} P &= \frac{N}{A} \\ &= \frac{m\, g}{A} \\ &= \frac{65.5\; {\rm kg} \times 9.81\; {\rm N \cdot kg^{-1}}}{0.20\; {\rm m} \times 0.40\; {\rm m}} \\ & \approx 8.0 \times 10^{3}\; {\rm Pa}\end{aligned}[/tex].
Thus, the [tex]55.5\; {\rm kg}[/tex] box exerts greater pressure on the ground than the [tex]65.5\; {\rm kg}[/tex] box.

what is frictional force?
how to Express frictional force?
Answer:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
Coefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force.
