The resistivity of the rod material is \(2.0 \times 10^{-6}\) Ω·m (to two significant figures).

The resistivity of the rod material can be calculated using the equation for resistivity, which is:

ρ = E / J

where ρ is the resistivity, E is the electric field, and J is the current density.

To find the current density, we need to divide the current by the cross-sectional area of the rod:

J = I / A

where I is current and A is the cross-sectional area.

Since the diameter of the rod is 1.0 cm, the radius is 0.5 cm or 0.005 m.

The cross-sectional area of the rod is:

A = πr^2

A = π(0.005 m)^2

A = 7.854 × 10^-5 m^2

Now we can find the current density:

J = I / A

J =\(50 A / 7.854 \times 10^{-5}m^2\)

J = 636619.772

Finally, we can calculate the resistivity:

ρ = E / J

=> 1.3 V/m / 636619.772 A/m^2

=>  \(2.04 \times 10^{-6}\)Ω·m

Passion

For me, standing on the summit of Mt Everest was the result of following a process. The process of mountaineering. I love mountaineering. I am passionate about it. I love the months of planning for an expedition, the months of sweating and training to prepare my body physically. The meticulous preparation of my equipment. Most of all I love the huge mental challenge I have to overcome before each climb to confront my own fear. All these reasons are why I climb, they are why I climbed Mt Everest and that is why I continue to climb.

Passion is an enormously powerful force. It gives us the strength to get through hard times and setbacks. It gives us strength to overcome our fears, to ignore what other people think of us, to be disciplined and make sacrifices in pursuit of our dreams. Passionate people do not want to take shortcuts – they consider that ‘learning the process’ is an important part of the journey.

In mountaineering it’s easy to spot those who are not passionate about the process. They want to stand on top of the mountain but they are not really interested in the process of climbing the mountain. I feel for these people. Success without hard work is a hollow, empty feeling. They never last long in the sport.

Just as in life, successful mountaineers are the ones who are passionate. They are not there just to stand on the summit. Their passion gives them the energy to work the hardest, fight the longest, and in the words of Winston Churchill “never, never. never give-up”.

Answer:

Impulse, J = 5 kg-m/s

Explanation:

Accoding to impulse-momentum theorem, the change in momentum of an object is equal to the impulse applied to it. In this problem, the change in momentum of an object is 5 kg-m/s.

We need to find the impulse necessary to change the momentum. So, impulse will be equal to 5 kg-m/s.

When Ryan runs underground around the outer edge of the merry-go-round in the opposite direction to its rotation, he adds up his angular velocity in relation to the merry-go-round.For the given problem, the concept of conservation of angular momentum should be used.

The given data is, Radius, r = 2.0 m

Diameter, d = 4.0 m

Moment of inertia, I = 500 kg m²

Angular velocity, ω = 2.0 rad/s

Mass of Ryan, m = 80 kg

The initial angular momentum of the merry-go-round can be represented as Iωi, which is equal to the final angular momentum of the merry-go-round and Ryan's combined system, which can be expressed as (I + mr²)ωf. In the final state, the merry-go-round and Ryan are moving with a common velocity of v.L = \(Iωi = (I + mr²)ωfv = rωf\)

Hence, we can find the final angular velocity of the merry-go-round as,ωf = ωi * (I / (I + mr²))= 2.0 * (500 / (500 + 80*2.0²))= 0.565 rad/sThe change in kinetic energy of the merry-go-round when it stops due to Ryan's impact is equal to the initial kinetic energy of the merry-go-round and Ryan's combined system.K.E. before = \(½ Iωi² + ½ mv²K.E.\)

after = ½ (I + mr²)ωf²K.E.

before = K.E. after\(½ Iωi² + ½ mv² = ½ (I + mr²)ωf²v = (Iωi - (I + mr²)ωf) / m = (500*2.0 - (500 + 80*2.0²)*0.565) / 80 = 1.62 m/s\)Therefore, the speed of Ryan when he jumped on was 1.62 m/s.

Answer:

We can use the formula for momentum to find the initial and final momentum of the body:

p = mv

where p is momentum, m is mass, and v is velocity.

Initial momentum:

p1 = mv1

p1 = 5 kg ( 2.0 m/s )

p1 = 10 kg m/s

Final momentum:

p2 = m(v2)

p2 = 5 kg ( 8.0 m/s )

p2 = 40 kg m/s

Therefore, the initial momentum of the body is 10 kg m/s and the final momentum is 40 kg m/s.

for b, we can use the formula for impulse to find the impulse received by the body:

J = F(t)

where J is impulse, F is force, and t is time.

To find the force, we can use Newton's second law of motion:

F = ma

The acceleration:

a = (v2 - v1) / t

a = (8.0 m/s - 2.0 m/s) / 5 s

a = 1.2 m/s^2

Now we can find the force acting on the body:

F = ma

F = 5 kg (1.2 m/s)^2

F = 6 N

Finally, we can find the impulse received by the body:

J = F(t)

J = 6 N5 s

J = 30 N s

Therefore, the body received an impulse of 30 N s

However, our bodies are not crushed by this pressure because we are able to withstand it. Our bodies are made up of fluids and solids, which are not easily compressible, and thus are able to maintain their shape even under pressure. Additionally, our internal organs exert a counter pressure, which helps balance the external pressure of the atmosphere. The human body has evolved over time to adapt to these environmental pressures, and we are able to live and function at sea level without being crushed by the air pressure.
