A jet plane lands with a speed of 87 m/s and can accelerate at a maximum rate of −4.10 m/s2 as it comes to rest. (a) From the in
garri49 [273]

Answer:

21.22s

Explanation:

initial velocity u=87m/s

acceleration a=-4.10 m/s²

velocity v=0

time t=?

From Newton's first law of motion

V=u+at

0=87-4.10t

-87=-4.1t

t= -87/-4.1

t= 21.22 s

When you sneeze, the air in your lungs accelerates from rest to approximately 150km/h in about 0.50 seconds. What is the acceler
miss Akunina [59]
(150 km/hr) x (1000 m/km) x (hr/3600sec)  =  41-2/3 m/sec

Acceleration  =  (change in speed) / (time for the change)

Change in speed  =  (41-2/3 minus 0) = 41-2/3 m/s
Time for the change = 0.5sec.

Acceleration = (41-2/3 m/s) / (0.5 sec)  =  83-1/3 m/s² .

Acceleration of gravity = 9.8 m/s² .

Acceleration of sneezed air = (83-1/3) / (9.8)  =  <em>8.5 g  </em>(rounded)

Svetradugi [14.3K]

Answer:

The formula for the separation between the plates, d = V/E and d = 1.02 mm

Explanation:

Here is the complete question

The electric field strength between the plates of a simple air Capacitor is equal to the voltage across the plates divided by the distance between them When a voltage of 112. V is put across the plates of such a capacitor an electric field strength of 1.1 kV/cm is measured. Write an equation that will let you calculate the distance d between the plates. Your equation should contain only symbols. Be sure you define each symbol

Solution

The electric field strength between the plates of a simple air capacitor is given by E = V/d where V = electric potential between the plates and d = separation between the plates.

Making d the separation between the plates subject of the formula, we have

d = V/E

Since V = 112 V and E = 1.1 kV/cm = 1100 V/cm

Substituting the values of the variables into the equation, we have

d = V/E

d = 112 V/1100 V/cm

d = 0.102 cm

d = 1.02 mm

So, the formula for the separation between the plates, d = V/E and d = 1.02 mm.
