LuckyWell [14K]

The distance covered is 66 m and the velocity would be 17 m/s

<h3>What are the three equations of motion?</h3>

There are three equations of motion given by  Newton

The first equation is given as follows

v = u + at

the second equation is given as follows

S = ut + 1/2×a×t²

the third equation is given as follows

v² - u² = 2×a×s

As given in the problem, An antelope moving with a constant acceleration of 2m/s2 covers crosses a point where its velocity is 5m/s

distance  =? meters

initial velocity(u) = 5  m/s

acceleration(a) = 2 m/s²

By using the second equation of motion given by newton

S = ut + 1/2at²

u= 5  m/s , a= 2 m/s² and t =6 seconds

S = 5*6 +0.5*2*6²

  =66 m

to calculate the velocity after 6 seconds by using the first question of the motion

v = u + at

v = 5 + 2*6

v = 17 m/s

Thus, the distance covered is 66 m and the velocity would be 17 m/s

What strength can accurately be attributed to the force of the throw?
ohaa [14]
Well for example if you’re throwing a ball The force that moves the ball "up"
must overcome (be larger than) the downward force of the ball's weight.
Once the upward "force of the throw" overcomes the weight, it must then accelerate the ball upward, in order to give an initial upward speed.
Newton's formula: Fnet = ma
indicates that the acceleration (a) will equal the *excess upward force* {once the weight force is cancelled} divided by the ball's mass.
so in summary:
Fnet in Newtons will be the child's UPward force minus the ball's weight.

You connect a 250-2 resistor, a 1.20-mH inductor, and a 1.80-uF capacitor in series across a 60.0-Hz, 120-V (peak) source. When
Basile [38]

Answer:

Explanation:

 reactance of inductor = wL = 2 X 3.14 X 60 X 1.2 X 10⁻³ = .45 ohm.

reactance of capacitor = 1/wC = 1/( 2 X 3.14 X 60 X 1.8 X 10⁻⁶ ) = 1474.4

Impedence of the circuit =[ R² + ( I/wC - wL)  ]¹/²  = [250² + ( 1474.4-.45 )]¹/²

Impedence = 1495 ohm.

RMS Voltage = 120/ 1.414 = 84.86 V

current = 84.86 / 1495 = 0.0576

Potential over resistance = 0.0576 x 250 = 14.2 V.

lapo4ka [179]

Answer:

      K =  \frac{h'}{8 m  \ \Delta x^2}K

Explanation:

The Heisenberg uncertainty principle is

          Δx Δp ≥ h' / 2

          h’ =\frac{h}{2\pi }

The kinetic energy of a particle is

          K = ½ m v²

           p = mv

           v = \frac{p}{m}

substitute

           K = \frac{1}{2}  \frac{p^2}{m}

from the uncertainty principle,

           Δp = \frac{h'}{2 \ \Delta x}

we substitute

          K = \frac{1}{2m} ( \frac{h'}{2 \ \Delta x})^2

          K =  \frac{h'}{8 m  \ \Delta x^2}
