As the speed of airplane is change due to jet stream
So the net speed is given as

now we can rearrange it as

now by the formula of vector difference we have

now plug in all values
![v_{plane} = \sqrt{365^2 + 136.73^2 - 2* 365* 136.73*cos22}[tex]v_{plane} = 243.7 km/hr](https://tex.z-dn.net/?f=v_%7Bplane%7D%20%3D%20%5Csqrt%7B365%5E2%20%2B%20136.73%5E2%20-%202%2A%20365%2A%20136.73%2Acos22%7D%3C%2Fp%3E%3Cp%3E%5Btex%5Dv_%7Bplane%7D%20%3D%20243.7%20km%2Fhr)
so above is the speed of the plane
The force between two objects is calculated through the equation,
F = Gm₁m₂/d²
where m₁ and m₂ are the masses of the objects. In this case, an unknown mass and Earth. d is the distance between them and G is universal gravitation constant.
In the second case, if the force is to become 2.5 times the original and all the variables are constant except d then,
2.5F = Gm₁m₂ / (D²)
D = 0.623d
Subsituting the known value of d,
D = 0.623(6.9 x 10^8) = <em>4.298 x 10^8 m</em>
An electron cloud is a visual model of the most probable locations of electrons in a atom. The cloud is denser where you will probably find a electron.
Answer: B. On the right side
Explanation: Metals are located on the left of the periodic table, and nonmetals are located on the upper right.
Answer:
<u>59637.2 N</u> force is required to lift the plane upward.
Explanation:
Mass of the aeroplane (m) = 5320 kg
Acceleration of the plane upward at a rate (a) = 1.40 m/s
"Newton's second law of motion", F - R = ma, where, "force" (F) acting on an object, (R) "resistive force", "mass" (m) of an object and "acceleration" (a).
Force = Resistive force + (mass × acceleration)
Resistive force = mass of an object × acceleration due to gravity. ( we know that acceleration due to gravity is 
Resistive force = 5320 × 9.81
Resistive force = 52189.2 N
Force = 52189.2 + (5320kg × 1.40 m/s)
Force = 59637.2 N
At takeoff, <u>59637.2 N</u> force is necessary to accelerate the plane upward at a rate of 1.40 m/s
