Answer:
The centripetal acceleration changed by a factor of 0.5
Explanation:
Given;
first radius of the horizontal circle, r₁ = 500 m
speed of the airplane, v = 150 m/s
second radius of the airplane, r₂ = 1000 m
Centripetal acceleration is given as;
![a = \frac{v^2}{r}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7Bv%5E2%7D%7Br%7D)
At constant speed, we will have;
![v^2 =ar\\\\v = \sqrt{ar}\\\\at \ constant\ v;\\\sqrt{a_1r_1} = \sqrt{a_2r_2}\\\\a_1r_1 = a_2r_2\\\\a_2 = \frac{a_1r_1}{r_2} \\\\a_2 = \frac{a_1*500}{1000}\\\\a_2 = \frac{a_1}{2} \\\\a_2 = \frac{1}{2} a_1](https://tex.z-dn.net/?f=v%5E2%20%3Dar%5C%5C%5C%5Cv%20%3D%20%5Csqrt%7Bar%7D%5C%5C%5C%5Cat%20%5C%20constant%5C%20v%3B%5C%5C%5Csqrt%7Ba_1r_1%7D%20%3D%20%5Csqrt%7Ba_2r_2%7D%5C%5C%5C%5Ca_1r_1%20%3D%20a_2r_2%5C%5C%5C%5Ca_2%20%3D%20%5Cfrac%7Ba_1r_1%7D%7Br_2%7D%20%5C%5C%5C%5Ca_2%20%3D%20%5Cfrac%7Ba_1%2A500%7D%7B1000%7D%5C%5C%5C%5Ca_2%20%3D%20%5Cfrac%7Ba_1%7D%7B2%7D%20%5C%5C%5C%5Ca_2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20a_1)
a₂ = 0.5a₁
Therefore, the centripetal acceleration changed by a factor of 0.5
Answer:
protein
Explanation:
protein is a very large complex macro-molecule that requires amino acids
Answer: 1896.55J/kg°C
Explanation:
The quantity of Heat Energy (Q) required to heat a material depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = 1320 joules
Mass of material = 5.61kg
C = ? (let unknown value be Z)
Φ = 0.124°C
Then, Q = MCΦ
1320J = 5.61kg x Z x 0.124°C
1320J = 0.696kg°C x Z
Z = (1320J / 0.696kg°C)
Z = 1896.55 J/kg°C
Thus, the specific heat of the material is 1896.55J/kg°C
Answer:
From smallest ratio to the largest ratio:
Coasting Universe - Critical Universe - Recollapsing Universe(From left to right)
Explanation:
The coasting universe is one that expands at a constant rate given by the Hubble constant throughout all of cosmic time. It has a ratio of actual density to critical density that is less than 1
The critical universe is one that is at balance with no expansion .I.e. the actual density and the critical density are equal, which makes the ratio of actual density to critical density to be equal to 1
Recollapsing Universe: The expansion of the universe reverses in the future and the universe eventually recollapses. The recollapsing universe has the ratio of the actual density to the critical density to be greater than 1
Answer:
The answer is: The increased voltage causes an increase in power usage, and the device will over-heat.
Explanation:
First, we must consider the variables of the electrical system that will allow us to respond. In this case, power, current and voltage, which are related by
![P=VI](https://tex.z-dn.net/?f=P%3DVI)
Where P=Power, V=Voltage, I=Current.
In the equation it can be observed that power is directly proportional to the system voltage. Thus, if the voltage increases as in this case, the power will also increase, which overheats the device and can cause damage to it.
