1 Ampere = 1 coulomb/second

1 hour = 3,600 seconds

1 coulomb/second = 3,600 coulomb/hour

10 Amperes x 1 hour = 36,000 coulomb/hour

The takeoff speed for an airbus a320 jetliner is 82 m/s . velocity data measured during takeoff are as follows: t(s) vx(m/s) 0 0
bulgar [2K]

The table is:

t(s)  vx(m/s)

0     0

10    23

20   46

30   69

a) from the data in the table, we observe that the acceleration is constant (because the rate of change in velocity is the same for each time interval of 10 seconds), so we can choose just one interval and calculate the acceleration as the ratio between the change in velocity and the change in time. Taking the first interval, we find

a=\frac{\Delta v_x}{\Delta t}=\frac{23 m/s-0}{10s -0}=2.3 m/s^2


b) To find the jet's acceleration in g's, we just need to divide the acceleration in m/s^2 by the value of g, the acceleration of gravity (9.81 m/s^2), so we find

a_g=\frac{a}{g}=\frac{2.3 m/s^2}{9.8 m/s^2}=0.23 g


c) the wheels leave the ground when the jet reaches its take-off velocity, which is 82 m/s.

At t=0s, the velocity of the jet is 0. We know that the acceleration is constant (a=2.3 m/s^2), so we can find the time t at which the jet reaches a velocity vf=82 m/s by using the equation

v_f = v_i +at

Re-arranging and substituting numbers, we find

t=\frac{v_f}{a}=\frac{82 m/s}{2.3 m/s^2}=35.65 s

the force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity
PIT_PIT [208]

The force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity is known as weight.

Weight is the force of gravity acting on a body.

The formula is :

                                W =mg

Here,

W is the weight or force acting on the body. m is the mass of the body, and g is the gravitational acceleration.

Since weight is also a force, so its SI unit is also newton. The value of weight varies from place to place depending on the gravity. Its value can also be equal to zero.

You walk 20 meters north, then 5 meters south. what is your displacement?
Svetllana [295]
The answer is C. 15 meters North

Displacement is the distance and direction from the origin. If you move 20 meters North, your displacement is 20 meters North. If you move 5 meters South, you are basically moving back the way you came by 5 meters, which means you are now 15 meters North.

I hope this helped! :)

What does a tachometer measure?
nlexa [21]
A tachometer measures, for example it measures the MPH(Miles Per Hour) in a car.  So like it measures your speed, so you could be going 100 MPH.
