Review. For a certain type of steel, stress is always proportional to strain with Young's modulus 20 × 10¹⁰ N/m² . The steel has density 7.86× 10³kg / m³. It will fail by bending permanently if subjected to compressive stress greater than its yield strength бy = 400MPa. A .rod 80.0cm long, made
of this steel, is fired at 12.0 m/s straight at a very hard wall.(d) the strain

Answers

The strain in the rod is [tex]2.37\times 10^{-3}[/tex]

Given:

Young's modulus, Y = [tex]20 \times 10^{10}\;N/m^{2}[/tex]

Steel density, [tex]\rho = 7.86 \times 10^{3}\;kg/m^{3}[/tex]

Length of the rod, L = 80 cm = 0.800m

The speed of the wave in the rod is,

[tex]$v = \sqrt{\frac{Y}{\rho}} = \sqrt{\frac{20\times 10^{10}\ \mathrm{N/m^2}}{7.86\times 10^3\ \mathrm{kg/m^3}}} = 5044\ \mathrm{m/s}$[/tex]

Hence the time taken by the wave to travel the end of the rod is,

[tex]$t=\frac{L}{v} = \frac{0.800\ \mathrm{m}}{5044\ \mathrm{m/s}} = 1.58\times 10^{-4}\ \mathrm{s}$[/tex]

The velocity of the rod is, [tex]$v_r = 12.0\ \mathrm{m/s}$[/tex]

The other end will keep moving after the front end hits the wall until the wave reaches the other end, given the period determined by the above problem.

As a result, before the wave reaches the end of the rod, it has traveled a distance of

[tex]$\Delta L = v_r t = (12.0\ \mathrm{m/s}) (1.58\times\ \mathrm{s}) = 1.90\times 10^{-3}\ \mathrm{m} = 1.90\ \mathrm{mm}$[/tex]

The strain in the rod is given by,

[tex]$\frac{\Delta L}{L} = \frac{1.90\times 10^{-3}\ \mathrm{m}}{0.800\ \mathrm{m}} = 2.37\times 10^{-3}[/tex]

Hence, the strain in the rod is [tex]2.37\times 10^{-3}[/tex].

A horizontal compass placed at the coil's center is made to deflect 45.0° from magnetic north by a current of 0.600 A in the coil.(b) The current in the coil is switched off. A "dip needle" is a magnetic compass mounted so that it can rotate in a vertical north-south plane. At this location, a dip needle makes an angle of 13.0° from the vertical. What is the total magnitude of the Earth's magnetic field at this location?

Answers

The total Earth's magnetic field is 56 μT.

The magnetic influence on moving magnetic materials, electric charges, and electric currents is described by a magnetic field, which is a vector field. A force acting on a charge while it travels through a magnetic field is perpendicular to both the velocity and the magnetic field.

The axis of a circular coil with five turns and a diameter of D = 30.0 cm, oriented vertically, is perpendicular to the horizontal component of the Earth's magnetic field.

When positioned in the coil's center, a horizontal compass deviates 45.0° from magnetic north due to a coil current of I = 0.600 A.

Now, the current is switched off.

The dip needle makes an angle of Φ = 13.0°.

Let B be the magnetic field and R be the radius of the circular coil.

Then the total magnitude of the Earth's magnetic field will be:

B(h) = B sin Ф

B = B(h) / sin Ф

B = ( 12.6 μT ) / ( sin 13.0° )

B = 56 μT

A variable is defined as an object or item that can have more than one single value.

A variable is defined as a quantity that can have more than one single value.

In the context of mathematics and science, a variable is a symbol or quantity that can change or vary. It represents an unknown or changing value that can take on different values in different situations or scenarios. Variables are used to describe relationships, equations, and patterns in various fields such as mathematics, physics, economics, and more.

Variables are an essential concept in scientific research and experimentation. They allow scientists to investigate how changes in one factor can affect another factor. In an experiment, variables are typically categorized into two main types: independent variables and dependent variables. The independent variable is the one that the researcher manipulates or controls to observe its effect on the dependent variable, which is the outcome being measured.

For example, in a study investigating the effects of different amounts of fertilizer on plant growth, the amount of fertilizer would be the independent variable, as it is being controlled by the researcher. The plant growth would be the dependent variable, as it depends on the different amounts of fertilizer applied.

Overall, variables are fundamental components of scientific inquiry, data analysis, and problem-solving, enabling researchers and scientists to understand and describe the relationships and patterns within various phenomena.

Two long, parallel conductors, separated by 10.0cm, carry currents in the same direction. The first wire carries a current I₁ = 5.00A, and the second carries I₂ = 8.00 A. (d) What is the force per length exerted by I₂ on I₁?

Answers

The force per unit length by I₂ on I₁ is 8 × 10⁻⁵ N/m.

The force between two parallel currents I₁ and I₂ that are spaced apart by r is measured as the ratio F/L. If the currents are flowing in the same direction, the force is attracting; if not, it is repulsive.

Currents are carried in the same direction by two lengthy parallel conductors that are spaced apart by 10.0cm.

I₁ = 5.00 A and I₂ = 8.00 A are the currents carried by the first and second wires, respectively.

r = 10 cm

Let the current flow along both wires in the x direction, with the first wire located at y = 0 and the second at y = 10 cm.

Now, the magnitude of the magnetic field created by I₂ at the location of I₁ is:

[tex]B = \frac{\mu_{0} I}{2 \pi r}(-\hat{k})[/tex]

[tex]B = \frac{4 \pi \times 10^{-7} \times 8}{2 \pi \times 0.1}[/tex]

[tex]B = (1.60 \times 10^{-5})(-\hat{k})[/tex]

Then the force per unit length exerted by I₂ on I₁ will be:

[tex]F_B = I_{1}( L \times B) = (5) [ (1)\hat{i} \times 1.60 \times 10^{-5}(-\hat{k}) ][/tex]

[tex]F_B = 8 \times 10^{-5}{~} N[/tex] towards the second wire.

Use the equation F = m · a (Newton's Second Law) to solve.

We are given the force and mass, so plug these values into the equation:

60 = 20a

Divide both sides by 20:

60/20 = 20a/20

After the collision the red ball has a velocity of 2m/s left and the green ball is rolling to the left with a velocity of 4.5m/s left. What is the mass of the green ball?​

Answers

The question is confusing for the initial direction of the green ball. We assume to the left.

Answer:

The mass of the green ball is 360 Kg

Explanation:

Law Of Conservation Of Linear Momentum

The total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and velocity v is

P=mv.

If we have a system of bodies, then the total momentum is the sum of the individual momentums

[tex]P=m_1v_1+m_2v_2+...+m_nv_n[/tex]

If some collision occurs, the velocities change to v' and the final momentum is:

[tex]P'=m_1v'_1+m_2v'_2+...+m_nv'_n[/tex]

In a system of two masses, the law of conservation of linear momentum

is written as:

[tex]m_1v_1+m_2v_2=m_1v'_1+m_2v'_2[/tex]

Let's call m1=30 Kg the mass of the red ball moving to the right at v1=4 m/s, m2 (unknown) the mass of the green ball moving at v2=-5 m/s to the left (assumed).

After the collision, the red ball rolls to the left at v1'=-2 m/s and the green ball is at v2'=-4.5 m/s. Thus:

[tex]30*4+m_2*(-5)=30*(-2)+m_2(-4.5)[/tex]

Operating:

[tex]120-5m_2=-60-4.5m_2[/tex]

[tex]120+60=5m_2-4.5m_2[/tex]

[tex]180=0.5m_2[/tex]

[tex]m_2=180/0.5=360[/tex]

The mass of the green ball is 360 Kg
