Answer:
The force constant of the spring, k = 3.15N/m
The maximum velocity Vmax = 1.44m/s
amax = 4.21m/s
Explanation:
The amplitude I half the distance between the points 1.06m and 2.05m. = 0.495
The complete solution can be found below in the attachment.
Thank you very much for e reading and I hope this is helpful to you.
Answer:
Density is directly proportional to pressure
Explanation:
As pressure increases (with constant temperature), density also increases.
Density is inversely proportional to temperature.
<span>2. For each pair of substances, identify the substance that will take more energy to heat from 20C to 100C and explain why. Specific heat for water- 4180 J/kg°C. Specific Heat for silver- 235 J/kg°C. Specific heat for iron-450 J/kg°C.
a. 30 g of water vs. 300 g of water
Q = mcp</span>ΔT
Q(water) = (0.03kg)(4180 J/kg°C)(100-20)
<span>Q(water) = 10,032 J
</span>Q(water) = (0.3kg)(4180 J/kg°C)(100-20)
Q(water) = 100,320 J
<span>300g of water takes mroe heat than 30g of water.
b. 500 g of iron vs. 500 g of silver
</span>Q = mcpΔT
Q(iron) = (0.5g)(-450 J/kg°C)(100-20)
Q(iron) = -18,000J
Q(silver) = (.5g)(-235 J/kg°C)(100-20)
Q(silver) = -9,400J
Iron gives off more heat than silver

Answer:
<h2>1584 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 528 × 3
We have the final answer as
<h3>1584 N</h3>
