Answer:
0.3659
Explanation:
The power (p) is given as:
P = AeσT⁴
where,
A =Area
e = transmittivity
σ = Stefan-boltzmann constant
T = Temperature
since both the bulbs radiate same power
P₁ = P₂
Where, 1 denotes the bulb 1
2 denotes the bulb 2
thus,
A₁e₁σT₁⁴ = A₂e₂σT₂⁴
Now e₁=e₂
⇒A₁T₁⁴ = A₂T₂⁴
or
![\frac{A_1}{A_2} =\frac{T_{2}^{4}}{T_{1}^{4}}](https://tex.z-dn.net/?f=%5Cfrac%7BA_1%7D%7BA_2%7D%20%3D%5Cfrac%7BT_%7B2%7D%5E%7B4%7D%7D%7BT_%7B1%7D%5E%7B4%7D%7D)
substituting the values in the above question we get
![\frac{A_1}{A_2} =\frac{2100_{2}^{4}}{2700_{1}^{4}}](https://tex.z-dn.net/?f=%5Cfrac%7BA_1%7D%7BA_2%7D%20%3D%5Cfrac%7B2100_%7B2%7D%5E%7B4%7D%7D%7B2700_%7B1%7D%5E%7B4%7D%7D)
or
=0.3659
The correct answer is C. 1995
Explanation:
The graph shows the changes in the harvest of Atlantic cod. In general, this graph illustrates how the peak occurred in the 1980s but then there was a sudden and sharp decline in 1995. Indeed, 1995 is the year with the lowest number of harvested cod as in this year there were approximately least than 10 thousand metric tonnes of cods. Also, this year shows the collapse of fishing stocks or that the population of this fish collapsed, which made it impossible to harvest as many fish as in previous years. According to this, the year that shows the collapse of fishing stocks is 1995.
This question involves the concepts of Newton's Second Law of Motion.
The acceleration of the bowling ball will be "0.67 m/s²".
<h3>Newton's Second Law of Motion</h3>
According to Newton's Second Law of Motion, when an unbalanced force is applied on an object, it produces an acceleration in it, in the direction of the applied force. This acceleration is directly proportional to the force applied and inversely proportional to the mass of the object. Mathematically,
![F=ma\\\\a=\frac{F}{m}](https://tex.z-dn.net/?f=F%3Dma%5C%5C%5C%5Ca%3D%5Cfrac%7BF%7D%7Bm%7D)
where,
- a = acceleration = ?
- F = Magnitude of the applied force = 6 N
- m = Mass of the ball = 9 kg
Therefore,
![a=\frac{6\ N}{9\ kg}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B6%5C%20N%7D%7B9%5C%20kg%7D)
a = 0.67 m/s²

Answer:
No, it will not and this has a historical importance. The reason is that transformers work via induction of electrical forces by changes in magnetic fields, so the constat fields produced by dc currents won't work at all
