A positively charged particle initially at rest on the ground accelerated upward to 100m/s in 2.00s. If the particle has a charg
VashaNatasha [74]

Answer:

Explanation:

From the question we are told that

     The initial velocity is  u  =  100 m/s

       The time taken is  t = 2.0 s

       The charge to mass ratio is  Q/m  =  0.100 C/kg

       

Generally the acceleration is mathematically evaluated as

              a  =   \frac{u}{t }

substituting values  

               a =   \frac{100}{2}

                a =  50 \ m/s^2

The electric field is mathematical represented as

             E = \frac{(a+g)}{Q/m}

substituting values

              E = \frac{(50+9.8)}{0.100}

              E = 598 \ N/C

How long will be required for an object to go from a speed of 22m/s to a speed of 27m/s if the acceleration is 5.93m/s^2 ?
mario62 [17]

Answer:

Required time, t = 0.84 seconds

Explanation:

It is given that,

Initial speed of an object, u = 22 m/s

Final velocity of an object, v = 27 m/s

Acceleration, a = 5.93 m/s²

We have to find the time required for an object to go a speed of 22 m/s to a speed of 27 m/s. It can be solved by using first equation of motion as:

v=u+at

Where

t = time

t=\dfrac{v-u}{a}

t=\dfrac{27\ m/s-22\ m/s}{5.93\ m/s^2}

t = 0.84 seconds

Hence, the time required for an object is 0.84 seconds.

Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.625×10−3 m3/s and
Tems11 [23]

Answer:

<em>0.153 m/s</em>

<em></em>

Explanation:

The flowrate Q = 0.625 x 10-3 m^3-/s

The diameter of the nozzle d = 5.19 x 10^-3 m

the velocity V = ?

The cross-sectional area of the flow A = \pi d^{2}/4

==> (3.142 x 5.19 x 10^-3)/4 = 4.077 x 10^-3 m^2

From the continuity equation,

Q = AV

V = Q/A = (0.625 x 10-3)/(4.077 x 10^-3) = <em>0.153 m/s</em>

The lamborghini murcielago can accelerate from 0 to 27.8 m/s (100 km/hr or 62.2 mi/hr) in a time of 3.40 seconds. Determine the
Ostrovityanka [42]

To determine the acceleration of the car, we use equation of motion

v = u +at

Here, v is final velocity of the car, u is the initial velocity of the car, a is the acceleration of the car in time t.

Given, v = 27.8 \ m/s , u=0 because car accelerate from 0 and t = 3.40 s.

Substituting these values in above equation, we get

27.8 \ m/s = 0 +  a \times 3.40 \ s \\\\ a= \frac{27 .8 m/s}{3.40\ s} = 8.17 \ m/s^2

In mi/ h.s,

1 m = 0.000621371 mile.

1 s = (1/3600 ) hour =   0.000277778 hour.

Therefore,

8.17 \ m/s^2 = 18.2757695061 \ mi/h.s (mile \ per \ hour \ second)
