Answer:
He would have to add <u>Top Soil </u>
Explanation:
My Mom grows a punch of plants so I asked her and she said Top Soil but if this is not the answer I am sorry :)
Answer:
<em>the minimum speed that the ball must have so that the cord does not become slack is</em> <em>2.02 m/s.</em>
<em></em>
Explanation:
In order to avoid slack, the centripetal force of the ball must equal its weight at the top of the circle. Therefore,
F_c = F_g
m v² / r = m g
v² = g r
v = √[g r]
v = √[(9.8 m/s²)(0.417 m)]
<em>v = 2.02 m/s </em>
Therefore,<em> the minimum speed that the ball must have so that the cord does not become slack is</em> <em>2.02 m/s.</em>
Answer:
The correct answer is B-25 V
Explanation:
We apply Ohm's Law, according to which:
V = i x R
V = 5A x 5Ω
V= 25 V
Being V the potential difference whose unit is the VOLT, i the current intensity (Ampere) and R the electrical resistance (ohm)
Answer:
In thermodynamics, heat is transferred energy that moves between substances or systems because of their temperature difference. According to the first law of thermodynamic and the law of energy conversion s a form of energy, heat is cannot be created or destroyed only moves from one form to other.
The stone gets heat energy from fire and moves this heat energy or thermal energy to water as it cools off and the water warms up. Heat moves or is transferred spontaneously from the hot stone into the cold water. Eventually, the stone and water have the same temperature and water becomes heated. At the time of heat flowing out of the stone into the water, the heat energy became less ordered, due to spreading out through both the stone and the water. This is a net increase in entropy which is the second law of entropy.
Remember the following formulas to convert temperatures between Farenheit and Celsius:
Convert all the temperatures to Celsius to compare them.
<h2>
Part a)</h2>
Convert 265ºF to Celsius:
Then, 265ºF is equal to 129.444...ºC. Then, 265ºC is higher than 265ºF.
The correct choice is option 2) 265ºC.
Part b)
Convert 370ºF to Celsius:
Then, 370ºF is equal to 187.777...ºC. Then, 200ºC is higher than 370ºF.
The correct choice is option 2) 200ºC.
