Answer:

(A) Aircraft instruments are color coded to direct attention to operational ranges and limitations

Explanation:

The only correct statement is that Aircraft instruments are color coded to direct attention to operational ranges and limitations.

The six basic air instruments that provide a pilot with information (speed, altitude, climb/descent, attitude, heading, and turning/banking) about an aircraft are; divided into two, Pitot-static instruments and Gyroscopic instruments.

Top (Pitot-static instruments):

- Airspeed Indicator (ASI)

- Altimeter

- Vertical Speed Indicator (VSI)

Bottom (Gyroscopic instruments):

- Attitude Indicator (AI)

- Heading Indicator (HI)

- Turn Coordinator (TC)

If the mass of an object is 100 and Net force is 400, what would be the Acceleration?

ira [324]

Answer:

$4m/s^{2}$

Explanation:

I'm assuming the units for force and mass are Newtons and kilograms, respectively.

Rearranging Newton's first law (F=m*a) to solve for acceleration:

F=m*a

$a=\frac{F}{m}=\frac{400 N}{100 kg}=4m/s^{2}$

The acceleration is 4 meters per second squared and was found by rearranging Newton's first law in order to solve for acceleration.

What is the net force on this object?

vaieri [72.5K]

Answer:

200 newtons

Explanation:

because the sub air that would pull the force down by all of the mass of the sub air go down by that 400 newtons there for your anwer is 200 newtons. because 600-400=200

A 5.30 g bullet moving at 963 m/s strikes a 610 g wooden block at rest on a frictionless surface. The bullet emerges, traveling

Tems11 [23]

Answer:

a) $V_{wf}$ = 4.67m/s

b) V = 8.29 m/s

Explanation:

Givens:

The bullet is 5.30g moving at 963m/s and its speed reduced to 426m/s. The wooden block is 610g.

a) From conservation of linear momentum

Pi = Pf

$m_{b}V{b_{i} } + V_{wi} = m_{w} V_{wf} + m_{b}V_{bf}$

where $m_{b},V{b_{i}$ are the mass and the initial velocity of the bullet, $m_{w}$ and $V_{wi}$ are the mass and the initial velocity of the wooden block, and $V_{wf}$ and $V_{bf}$ are the final velocities of the wooden block and the bullet

The wooden block is initial at rest $(V_{wi} = 0)$ this yields

$m_{b}V{b_{i} } = m_{w} V_{wf} + m_{b}V_{bf}$

By solving for $V_{wf}$ adn substitute the givens

$V_{wf}$ = $\frac{m_{b}V_{bi} - m_{b} V_{bf} }{m_{W} }$

= $\frac{5.3(g)(963(m/s)-426(m/s) }{610(g)}$

$V_{wf}$ = 4.67m/s

b) The center of mass speed is defined as

$V = \frac{m_{b} }{m_{b}+m_{w} } V_{bi}$

substituting:

$V = \frac{5.3(g)}{5.3(g)+610(g)} X 963(m/s)$

V = 8.29 m/s

a stone is tied to a string and whirled around in a circle at a constant speed. is the string more likely to break when the circ

DochEvi [55]

Answer:

The string is more likely to break when the circle is vertical

Explanation:

The string is more likely to break when the circle is vertical because tension in the string is the same throughout the circular motion and it is equal to mrw^2 when it is rotated in the horizontal plane while tension in the string is maximum and is given by mrw^2+mg when in the vertical plane.
