Answer:
17.71N/m
Explanation:
The period of the spring is expressed according to the expression;
m is the mass of the object
k is the force constant
Given
m = 5.50kg
T = 3.50s
Substitute into the formula;
Hence the force constant of the spring is 17.71N/m
Answer:
408.33watts
Explanation:
Power is expressed according to the formula
Power = work done/time
Power = force × distance/time
Power = Force× velocity
Find the force
F = mv/t
F = 600×1.75/4.5
F = 1050/4.5
F=233.33N
Get the power
Power = 233.33×1.75
Power = 408.33watts
Hence the average power of the elevator motor during this period is 408.33m/s
Answer:
The rocks location is underneath an ocean or mountain
Explanation:
Silicic rock are igneous rock rich in silica. The amount of silica that constitutes a silicic rock is usually defined as at least sixty three percent. Granite and rhyolite are the most common silicic rocks found. These are found in the magma of the Earth.
Silicic is the group of silicate magmas which crystallise a relatively small proportion of ferromagnesian silicates. The main constituents of a silicic rock will be minerals rich in silica-minerals mainly.
