Convection currents cause the magma under the trench to slowly rise causing the trench to open up further releasing this magma at the same time.
Answer:
Assuming the typical saw used to saw boards in home construction and renovation is a circular saw, the diameter of the blade can be estimated as 7-10 inches (17.8-25.4 cm). The linear speed in m/s of a point on the rim of the circular saw blade is then approximately: (π × 25.4 cm) × (2600 rev/min) / (60 s/min) = 28.0 m/s.
C I’m not that sure though
Use the right equation. To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos (x) For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline.
