The Pinnacles and Neenach volcanics are 23.5 million-year-old andesite to rhyolite outcrops, on either side of the San Andreas F

ault, today separated by ~320 kilometers. If they were originally products of the same eruptive center, they have been offset along the San Andreas Fault by 320 kilometers in 23.5 million years. What is the rate of offset in centimeters per year?

Answer:

v = 1.36 cm / y

Explanation:

For this exercise we must assume that the displacement of the plates is constant over time, so we will use the kinematic relationships for the uniform movement

      v = d / t

We reduce the quantities to the SI system

     d = 320 km (1000 m / 1km) (100 cm / 1 m)

     d = 3.2 107 cm

let's calculate

     v = 32.107 / 23.5 106

     v = 1.36 cm / y

The thermal energy in a heat engine is used to move a piston. Which best describes why this is possible?
Natali [406]

Answer:

The increase in thermal energy results in an increase in pressure.

Explanation:

  • The increase in entropy is directly related to the increase in temperature. So the thermal energy in heat engine increases the temperature of that surrounding.
  • Higher temperature means the kinetic energy of particles is also higher, their vibration is increasing. So it increases the pressure (ideal gas law).
  • In this way the increment in the thermal energy in heat engine moves piston by increasing the pressure.

5) Find the initial velocity for a 700 kg car that
Serhud [2]

Answer:

Δv = 12 m/s, but we are not given the direction, so there are really an infinite number of potential solutions.

Maximum initial speed is 40.6 m/s

Minimum initial speed is 16.6 m/s

Explanation:

Assume this is a NET impulse so we can ignore friction.

An impulse results in a change of momentum

The impulse applied was

p = Ft = 1400(6.0) = 8400 N•s

p = mΔv

Δv = 8400 / 700 = 12 m/s

If the impulse was applied in the direction the car was already moving, the initial velocity was

vi = 28.6 - 12 = 16.6 m/s

if the impulse was applied in the direction opposite of the original velocity, the initial velocity was

vi = 28.6 + 12 = 40.6 m/s

Other angles of Net force would result in various initial velocities.
