Allushta [10]

Answer:

33.7410805301 s

22336.5953109 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity = $4\times 331$

s = Displacement

a = Acceleration = $4g=4\times 9.81\ m/s^2$

g = Acceleration due to gravity = 9.81 m/s²

$v=u+at\\\Rightarrow t=\dfrac{v-u}{a}\\\Rightarrow t=\dfrac{4\times 331-0}{4\times 9.81}\\\Rightarrow t=33.7410805301\ s$

The time taken is 33.7410805301 s

$s=ut+\dfrac{1}{2}at^2\\\Rightarrow s=0\times t+\dfrac{1}{2}\times 4\times 9.81\times 33.7410805301^2\\\Rightarrow s=22336.5953109\ m$

The plane would travel 22336.5953109 m

A hydraulic system contains 3 pistons. The input piston has an area of 0.625 in2, one of the output pistons ( piston A ) has an

Xelga [282]

The area of Piston A is 13.88 in^2

What is a hydraulic system?

The hydraulic system functions by using pressurized fluid. The power of liquid fuel in hydraulics is significant and as a result, they are commonly used in heavy equipment.

Hydraulic system simply means a mechanical function that operates through the force of liquid pressure.

Here

A hydraulic system contains 3 pistons.

Pressure, P = 1440 psi

for piston A:

Area, A= 0.625 in^2

Force, F = 20,000 lb

We know that,

Force = Pressure x Area

F = P x A

Area ( piston A) = F / P

A = 20,000 / 1440

A = 13.88 in^2

Hence,

The area of Piston A is 13.88 in^2

A woman wears bifocal glasses with the lenses 2.0 cm in front of her eyes. The upper half of each lens has power-0.500 diopter a

saveliy_v [14]

Answer:

q = -2 m and q = -0.5 m

Explanation:

For this exercise we must use the equation of the optical constructor

1 / f = 1 / p + 1 / q

where f is the focal length, p and q are the distance to the object and the image, respectively

Let's start with the far vision point, in this case the power of the lens is

P = -0.5D

power is defined as the inverse of the focal length in meter

f = 1 / D

f = -1 / 0.5

f = - 2m

the object for the far vision point is at infinity p = infinity

1 / f = 1 / p + i / q

1 / q = 1 / f - 1 / p

1 / q = -1/2 - 1 / ∞

q = -2 m

The sign indicates that the image is on the same side as the object

Now let's lock the near view point

D = +2.00 D

f = 1 / D

f = 0.5m

the near mink point is p = 25 cm = 0.25 m

1 / f = 1 / p + 1 / q

1 / q = 1 / f - 1 / p

1 / q = 1 / 0.5 - 1 / 0.25

1 / q = -2

q = -0.5 m

the sign indicates that the image is on the same side as the object in front of the lens

a solid cubic centimeter of platinum weighs 21.5 N. if this cube of platinum is placed under water, what volume of water is disp

slava [35]

Answer:

Mp =Pp g where p = density of solid Platinum

Wp = Mp Pp g weight of mass M

Volume displaced is 1 cm^3

Weight of water = .0098 N since 1 cm^3 displaced

Or Ww = 1 cm^3 * .001 kg / cm^3 * 9.8 N/kg = .0098 N

a circuit element having terminals a and b has vab = 10v and iba = 2a over a period of 20s, how much charge moves throught the e

PIT_PIT [208]

Answer: charge Q = 40Coulombs

Explanation: The current in a circuit is the quantity of charge that flows through it per second.

Here the 2amp current is same as the amount of charge in coulomb that flows through the terminal in ONE second.

So, if 2 coulomb of charge flows in 1sec then in 20 secs we will have

Q(charge) = 2*20 = 40 coulombs
