The best represent the size of visible light will be C. Protozoa

The electromagnetic spectrum, gives the overall distribution of electromagnetic radiation by the frequency or wavelength. All EM waves travel at the speed of light in a vacuum, but over a wide range of frequencies, wavelengths, and photon energies.

Visible light wavelengths cover the range of approximately 0.4 to 0.7 μm. electromagnetic spectrum that the human eye can see is the Visible light. Visible light is a form of electromagnetic (EM) radiation, along with radio waves, infrared, ultraviolet, X-rays, and microwaves. the wavelengths that are visible to most human eyes is generally known as Visible light

Determine el valor del ángulo de tiro de un proyectil que tarda en impactar en 8s y que tuvo un alcance de 0,3km.

Gelneren [198K]

Answer:

$46.3^{\circ}$

Explanation:

The motion of a projectile consists of two independent motions:

- A uniform motion along the horizontal direction (constant velocity)

- A uniformly accelerated motion along the vertical direction (constant acceleration)

The time of flight of a projectile is given by

$t=\frac{2u_y}{g}$

where

$u_y$ is the initial vertical velocity

$g=9.8 m/s^2$ is the acceleration due to gravity

Here the time of flight is

t = 8 s

So, the initial vertical velocity is:

$u_y=\frac{gt}{2}=\frac{(9.8)(8)}{2}=39.2 m/s$

At the same time, the horizontal distance covered by the projectile is given by

$d=u_x t$

where

$u_x$ is the horizontal velocity, which is constant

t is the time of flight

Here we know that the range of the projectile is 0.3 km, so

d = 0.3 km = 300 m

So the horizontal velocity is

$u_x=\frac{d}{t}=\frac{300}{8}=37.5 m/s$

Therefore, we can find the angle of projection of the projectile by using:

$\theta=tan^{-1}(\frac{u_y}{u_x})=tan^{-1}(\frac{39.2}{37.5})=46.3^{\circ}$

A 2.0 kg cart has a momentum of 10.0 kg m/s. What is its velocity?

Svetach [21]

Answer:

$\boxed {\boxed {\sf C. \ 5.0 \ m/s}}$

Explanation:

Momentum is the product of mass and velocity. The formula is:

$p=mv$

The mass of the cart is 2.0 kilograms. The momentum is 10.0 kg m/s. The velocity is unknown.

$m= 2.0 \ kg \\p= 10.0 \ kg \ m/s$

Substitute the values into the formula.

$10.0 \ kg \ m/s= (2.0 \ kg ) v$

We want to solve for the velocity (v). Therefore we must isolate the variable. It is being multiplied and the inverse of multiplication is division. Divide both sides of the equation by 2.0 kg.

$\frac { 10.0 \ kg \ m/s}{2.0 \ kg}=\frac{(2.0 \ kg )v}{2.0 \ kg}$

The kilograms will cancel each other out.

$\frac { 10.0 \ m/s}{2.0}=v$

$5.0 \ m/s=v$

The velocity is <u>5 meters per second.</u>

What is the magnetic force value due to 3.5nanocoloumb charge moves to the

sertanlavr [38]

The force on the charge is 1.1×10⁻⁸ N.

<h3>What is force?</h3>

Force can be defined as the product of the mass of a body and its acceleration

To calculate the force on the charge, we use the formula below.

Formula:

F = qvBsin∅............. Equation 1

Where:

q = charge
v = velocity
B = magnetic field
∅ = Angle.

From the question,

Given:

B = 25 mT = 0.025 T
v = 250 m/s
q = 3.5 nC = 3.5×10⁻⁹ C
∅ = 30°

Substitute the given values into equation 1

F = (0.025)(250)(3.5×10⁻⁹)(sin30°)

F = 1.093×10⁻⁸ N
F ≈ 1.1×10⁻⁸ N

Hence, the force on the charge is 1.1×10⁻⁸ N.
