Answer:
Mass attached to the spring is 41.95 kg
Explanation:
We have given time period of the spring T = 2.1 sec
Let the mass attached is m
And spring constant is k
We know that time period is given by
---------eqn 1
Now if the mass is increased by 68.10 kg then time period become 3.4 sec
So ------eqn 2
Now dividing eqn 1 by eqn 2
So mass attached to the spring is 41.95 kg
The initial velocity of the hoop is determined as 8.854 m/s.
<h3>Conservation of energy</h3>
The initial velocity of the hoop can be determined from the principle of conservation of energy.
Final potential energy = Initial kinetic energy
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
2gh = v²
√2gh = v
√(2 x 9.8 x 4) = v
8.854 m/s = v
Thus, the initial velocity of the hoop is determined as 8.854 m/s.

Pressure = F/A
Where,
F = Force exerted = 150 N
A = Area = 1*0.5 = 0.5 m^2
Therefore,
Pressure exerted by wind on the wind = 150/0.5 = 300 N/m^2
1 N/m^2 = 1 Pa,
Then,
Pressure, P = 300 Pa
A soil rich in organic material is called loamy soil. A loamy soil is made up roughly of the same quantity of sand, clay and silt particles. From the information given above, we are told that Scott has a silt clay loam, which means that the percentage of the silt is the highest followed by the percentage of the clay. To improve this soil quality, Scott should adjust the quantities of the three particles in the soil in such a way that they have roughly the same amount. An example of such a combination is 40% clay, 30% sand and 30% silt.
Answer:
Inference
Explanation:
He is guessing that the power is out due to the fact that the light isn't turning on. However, we don't know if the power is really out or not, it could just be a broken light.
