State characteristics of the images formed by pin - hole camera

Leokris [45]

Answer:

Real image

Explanation:

The picture is real, but it is reversed and tiny. An picture generated by a pinhole camera has certain features. As compared item, the image created by a pinhole camera is normally pretty small and looks reversed both on the vertically and horizontally axis.

ASAP please!! <br>The force vectors on an aircraft are as shown. Find the net (resultant force).

ioda

Answer:

The magnitude of the net force is 5430N

Explanation:

I suggest to define the axes as aligned to the axis of the plane. This will require you to decompose only one vector, namely the Weight. We need two components of the W force: one in horizontal direction of the plane, the other perpendicular to it. Through a simple triangle argument you will se that the plane-horizontal component of W is

$W_D=3600 N\cdot\sin 27^\circ=1634N$

acting in the direction of the Drag, and the plane-perpendicular component is:

$W_L=-3600N\cdot\cos 27^\circ=-3208N$

with negative sign since it counteracts the Lift.

So the components of the netforce F are:

$F_h=T-D-W_D=(8000-1000-1634)N=5366N\\F_v=L+W_L=(4100-3208)N=829N$

The magnitude of the net force is:

$|F|=\sqrt{5366^2+829^2}N = 5430N$

Imagine holding a basketball in both hands, throwing it straight up as high as you can, and then catching it when it falls. At w

valentina_108 [34]

Answer:before throwing and after catching the ball

Explanation:

When basketball is in the hand of player net force on it zero as holding force is canceled by gravity Force. During its entire motion gravitational force is acting on the ball which is acting downward. Even at highest point gravity is constantly acting downwards.

After catching the ball net force on it zero as holding force is canceled by gravity force and ball is continue to be in stationary motion.

A satellite orbiting the moon very near the surface has a period of110 min. What is free-fall acceleration on the surface of the

Norma-Jean [14]

Answer:

1.54 m/s²

Explanation:

The free-fall acceleration is calculated as

g = w²r

Where w is the angular velocity of the satellite and r is the radius of the moon.

The angular velocity can be calculated as

$w=\frac{2\pi}{T}$

Where T is the period, so

T = 110 min = 110 x 60 s = 6600 s

Then,

$w=\frac{2\pi}{6600\text{ s}}=9.52\times10^{-4}\text{ rad/s}$

Finally, the radius of the moon is r = 1.7 x 10⁶ m, so the free-fall acceleration is

$\begin{gathered} g=w^2r \\ g=(9.52\times10^{-4})^2(1.7\times10^6) \\ g=1.54\text{ m/s}^2 \end{gathered}$

Therefore, the answer is 1.54 m/s²
