I believe the correct answer from the two choices above is the first set of choice. Properties of light that define light as a wave are <span>Wavelength, </span>
<span>Amplitude, </span><span>Period, </span><span>Frequency and speed. These terms are used and calculated to define a light as a wave. Hope this answers the question.</span>

If a 2kg ball has and initial velocity of
lakkis [162]

Answer:

\boxed {\boxed {\sf 12 \ Newtons }}

Explanation:

Force is equal to the product of mass and acceleration.

F=m*a

We know the mass, but not the acceleration. Therefore, we must calculate it before we can calculate force.

1. Calculate Acceleration

Acceleration is the change in velocity over the change in time.

a=\frac{V_f-V_i}{t}

The final velocity is 10 meters per second and the initial velocity is 4 meters per second. The time is 1 second.

V_f=10 \ m/s \\V_i= 4 \ m/s \\t= 1 \ s

Substitute the values into the formula.

a=\frac{10 \ m/s-4 \ m/s }{1 \ s}

Solve the numerator.

a=\frac{6 \ m/s}{1 \ s }

Divide.

a= 6 \ m/s/s=6 \ m/s^2

2. Calculate Force

Now we know the acceleration and the mass.

m= 2 \ kg \\a= 6 \ m/s^2

Substitute the values into the fore formula.

F= 2 \ kg * 6  \ m/s^2

Multiply.

F= 12 \ kg*m/s^2

  • 1 kilogram meter per square second is equal to 1 Newton.
  • Our answer of 12 kg*m/s² is equal to 12 Newtons

F= 12 \  N

The force applies to the ball was <u>12 Newtons.</u>

A rescue pilot drops a survival kit while her plane is flying at an ultitude of 2500m with a forward velocity of 95m. If the air
never [62]

Answer:

Approximately 2.1\; \rm km, assuming that g = -9.8\; \rm m \cdot s^{-2}.

Explanation:

Let t denote the time required for the package to reach the ground. Let h(\text{initial}) and h(\text{final}) denote the initial and final height of this package.

\displaystyle h(\text{final}) = \frac{1}{2}\, g\, t^2 + h(\text{initial}).

For this package:

  • Initial height: h(\text{initial}) = 2500\; \rm m.
  • Final height: h(\text{final}) = 0\; \rm m (the package would be on the ground.)

Solve for t, the time required for the package to reach the ground after being released.

\displaystyle t^{2} = \frac{2\, (h(\text{final}) - h(\text{initial}))}{g}.

\begin{aligned} t &= \sqrt{\frac{2\, (h(\text{final}) - h(\text{initial}))}{g} \\ &\approx \sqrt{\frac{2\times (0\; \rm m - 2500\; \rm m)}{(-9.8\; \rm m \cdot s^{-2})}} \approx 22.588\; \rm s\end{aligned}.

Assume that the air resistance on this package is negligible. The horizontal ("forward") velocity of this package would be constant (supposedly at 95\; \rm m \cdot s^{-1}.) From calculations above, the package would travel forward at that speed for about 22.588\; \rm s. That corresponds to approximately:95\; \rm m \cdot s^{-1} \times 22.588\; \rm s \approx 2.1 \times 10^{3}\; \rm m = 2.1\; \rm km.

Hence, the package would land approximately 2.1\; \rm km in front of where the plane released the package.

A 591 μF capacitor is discharged through a resistor, whereby its potential difference decreases from its initial value of 88.5 V
Stels [109]

Answer:

2.6 kilo Ohm

Explanation:

Capacitance, C = 591 μF = 591 x 10^-6 F

Vo = 88.5 V

V = 11.9 V

t = 3.09 s

Let the resistance is R.

V = V_{0}e^{\frac{-t}{RC}}

\frac{11.9}{88.5} = e^{\frac{-t}{RC}}

0.135 = e^{\frac{-t}{RC}}

Take natural log on oth the sides

ln 0.135 = - 3.09 / RC

RC = 1.545

R = 1.545 / ( 591 x 10^-6)

R = 2614.2 ohm

R = 2.6 kilo Ohm

Thus the resistance is  2.6 kilo Ohm.

describe what happens when light strikes a translucent material, transparent material , opaque material . give one specific exam
CaHeK987 [17]

Answer: according to https://www.doe.virginia.gov When light strikes translucent materials, only some of the light passes through them. The light does not pass directly through the materials. ... Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy.
