An airplane is accelerating forward due to a force of 3320 newtons acting

1 answer:

5 0

Two opposite forces generate a force whose magnitude is the difference of the two magnitudes, and whose direction is the same of the strongest one.

We have 3320 newtons forward, and 550 backwards.

So, the net force is forward, and has magnitude $3320-550=2770$

photoshop1234 [79]

Answer:

The distance the mass would stretch it is $x = 0.00992948$

The correct option is A

Explanation:

From the question we are told that

The period of the slit is $T = 0.2s$

The acceleration due to gravity is $g =9.8 m/s^2$

Generally the period is mathematically represented as

$T = 2 \pi \sqrt{\frac{m}{k} }$

Whee m is the particle and k is the spring constant

making $\frac{m}{k}$ the subject

$\frac{m}{k} = [\frac{T}{2 \pi} ]^2$

The weight on the particle is related to the force stretching the spring by this mathematical relation

$W = F_s$

$mg = kx$

where x is the length by which the spring is stretched

$\frac{m}{k} = \frac{x}{g}$

Substituting the equation above for $\frac{m}{k}$

$[\frac{T}{2 \pi} ]^2 = \frac{x}{g}$

making x the subject

$x = g [\frac{T}{2 \pi} ]$

Substituting the value

$x = 9.8 * [\frac{0.2}{2 * 3.142} ]^2$

$x = 0.00992948$

A common black ant discovers a piece of bread 85 cm east of the entrance of her nest. If the ant carries 10 bits of bread back t

babunello [35]

Answer:

19 x 85 = 1,615 for distance. Displacement is 0

Explanation:

The total distance traveled by the ant in 9 round trips and one 1/2 trip, or 19 one bash way trips: 19 x 85cm = 1615cm. The displacement of the ant after the tenth trip is 0 cm ( the displacement origin is the nest.)
