<u>Answer</u>
= 9.25 m/s
<u>Explanation</u>
The Newton's second law of motion states that, the change in momentum is directly propotional to the force producing it and it takes place in the direction of force.
F = ma
f = m(v-u)/t
ft = m(v-u)
∴ 55 × 45/1000 = 0.060(v - -32)
2.475 = 0.06(v + 32)
2.475/0.6 = v + 32
41.25 = v + 32
v = 41.25 -32
= 9.25 m/s
Answer:
The rate of deceleration is 15 km/h^2.
Explanation:
Since the car comes in 90km/h, it will need deceleration for 15 km/h for 6 seconds to finally stop the car. 15*6=90
Every unit on the map equals 25000 of the unit in real life.
Answer: It is brighter
Explanation: We are getting closer to the light because the earth is expanding.
Answer;
- Rock layers are placed under compressional stress: Reverse Fault
- Rock layers are placed under tensional stress: Normal Fault
- Hanging wall has dropped relative to footwall: Normal Fault
- Hanging wall has risen relative to footwall: Reverse faults
Explanation;
A normal fault occurs because two tectonic plates are pulling apart from each other, causing tensional stress. The stress allows gravity to pull the hanging wall downward along the footwall, making a cliff-like formation called a scarp. Thus, if you see the hanging wall has dropped relative to the footwall, it is a normal fault. Normal faults occur at divergent boundaries.
A reverse fault happens at convergent boundaries, where two plates colliding produce compressional stress. As the two plates come together, the pressure causes the hanging wall to move upward along the footwall. These breaks are reverse faults because the hanging wall moves in an opposite, or reverse, direction when compared to a normal fault.
A strike-slip fault occurs when tectonic forces cause rock layers to break apart and move in opposite, parallel directions, causing shear stress. The rock layers in a strike-slip fault move sideways past one another.
