Deduce the firstequation of motion matematical method​

Physics
1 answer:
Margarita [4]3 years ago
5 0

Answer:

The answer is below

Explanation:

Equation of motion is a term in physics that is used in explaining the characteristics of a physical system concerning its motion while considering the period.

The First Equation of Motion is given as v = u + at

Here, a = acceleration, v = final velocity, u = initial velocity, and t = time

To deduce it algebraically, it is written as

a = (v - u) ÷ t

Therefore, it can be repositioned to => v = u + a * t

4. A plane accelerates down a runway due to the constant resultant force of
Doss [256]

Answer:

See below

Explanation:

Net force acting on the plane after overcoming frictional forces is

2.7 x 10^6   -  6.8 x 10^4   -  8.5 x 10^5 = 1 782 000 N

Work = F x d

        = 1 782 000 x 1400 m = 2.5 x 10^9   J       or  2.5 x 10^6  kJ

QuesLUI 2 UI IU
Alika [10]

Answer:

D) The given reaction is Exothermic, because energy is released

Explanation:

Here, given that Zinc is added to a beaker containing hydrochloric acid.

Also, the beaker gets warm.

⇒The energy is released in the form of heat.

EXOTHERMIC reactions are those type of reactions in which energy is released in the form of heat.

When the beaker gets warm, the reaction is exothermic in nature.

Hence, the given reaction is Exothermic, because energy is released

A weather emergency siren is mounted on a tower, 105 m above the ground. On one hand, it would be a good idea to make the siren
Svetradugi [14.3K]

Answer:

Explanation:

101 dB = 10.1 B.

Maximum intensity of sound allowed = 10.1 B

Intensity of sound in terms of W/m² can be found as follows

log (I / I₀) = 10.1

I / I₀ = 10¹⁰°¹

I = I₀ X 10¹⁰°¹

= 10⁻¹² X  10¹⁰°¹

= 10⁻¹°⁹ W/m²

105 m above the ground the this intensity will be 105² times

intensity at source point = 10⁻¹°⁹ x 105²

= 138.79 W/m²

energy of sound from source

= 4π times

= 4 x 3.14 x 138.79

= 1743.28W/m²

To calculate in terms of decibel :

log 1743.28 / 10⁻¹²

= log 1743.28 +12

= 15.24 B

= 152.4 dB .

152.4 dB .

(a) Calculate the self-inductance (in mH) of a 55.0 cm long, 10.0 cm diameter solenoid having 1000 loops.
DedPeter [7]

Explanation:

(a) We have,

Length of solenoid, l = 55 cm = 0.55 m

Diameter of the solenoid, d = 10 cm

Radius, r = 5 cm = 0.05 m

Number of loops in the solenoid is 1000.

(a) The self inductance in the solenoid is given by :

L=\dfrac{\mu_o N^2A}{l}

A is area

L=\dfrac{4\pi \times 10^{-7}\times (1000)^2\times \pi (0.05)^2}{0.55}\\\\L=0.0179\ H\\\\L=17.9\ mH

(b) The energy stored in the inductor is given by :

E=\dfrac{1}{2}LI^2\\\\E=\dfrac{1}{2}\times 0.0179\times (19.5)^2\\\\E=3.4\ J

Hence, this is the required solution.
