Suppose you increase the height of the object without changing its depth under water. What will happen to the force due to press

Natali [406]

Answer:Remains same

Explanation:

Given

It is given that the depth is constant and we are only increasing the height of object submerged in the water

thus Force due to Pressure remains same as this force depends upon the depth of object with respect to free surface of Fluid.

Pressure at a depth h with density $\rho$ of fluid is given by

$P=\rho \times g\times h$

and $Force=Pressure \times area$

If an airplane were traveling eastward with a thrust force 450 N and there was a tailwind of 200 N, what would the resulting net

Alika [10]

The resulting net force is 650N

Explanation:

The force caused by air resistance against the plane's motion is called the Drag force. It acts against the motion of the plane. However, tailwinds push the plane from its tail and they apply a force is the direction of the moving plane.

The resulting force is the sum of the two forces; 450N +200N = 650N

how do i.... Find the angle between each pair of vectors below. (1 point each) a. a = 2x + 3y a = 4x + 2y

Shalnov [3]

Recall that the dot product between two vectors $\mathbf a$ and $\mathbf b$ satisfies

$\mathbf a\cdot\mathbf b=\|\mathbf a\|\|\mathbf b\|\cos\theta$

where $\|\mathbf x\|$ denotes the norm of a vector $\mathbf x$ , and $\theta$ is the angle between the two vectors.

So if $\mathbf a=(2,3)$ and $\mathbf b=(4,2)$ , then

$(2,3)\cdot(4,2)=\|(2,3)\|\|(4,2)\|\cos\theta$

$\implies2\cdot4+3\cdot2=\sqrt{2^2+3^2}\sqrt{4^2+2^2}\cos\theta$

$\implies\cos\theta=\dfrac{14}{\sqrt{13}\sqrt{20}}$

$\implies\theta\approx29.7^\circ$
