The ray more the incidence ray, the more will be the reflected ray. As angle of incidence is to angle of reflection.

Glare can be defined as the difficulty in seeing the object due to more brightness. The bright light such as the direct sunlight or the reflected sunlight or the headlight at the nighttime.The more the intensity the more will be glare.

Hence, the ray that will produce most glare is 70 degree.

A ray at which angle would produce the most glare is at 70 degrees. The answer is letter D. the greater the incident of light is, the greater is its index of refraction and thus having greater angle to produce a light ray.

Question 3 of 15

omeli [17]

Answer:

B) Degrees

Explanation:

The directions of the vectors are often defined in terms of due East, due North, due West and due South. A direction exactly in between of North and East can be described as Northeast, similarly we can describe directions in terms of Northwest, Southeast and South west.

From these, the direction of a vector can be easily expressed in degrees, which is measured counter clockwise about its tail from due East. Considering that we can say that East is at 0° , North is at 90° , West is at 180 and South is at 270° counter clockwise rotation from due East.

So, we know that the direction of a vector lying somewhere between due East i.e 0° and due North i.e 90°, will be measured in degrees, which will have a value between 0°-90°

What are the magnitude and direction of the acceleration of an electron at a point where the electric field has magnitude 6100 n

Hoochie [10]

Force on electron due to electric field is given by

$F = eE$

$F = 1.6 * 10^{-19}* 6100$

$F = 9.76 * 10^{-16} N$

now the acceleration is given by

$a = \frac{F}{m}$

$a = \frac{9.76 * 10^{-16}}{9.1 * 10^{-31}}$

$a = 1.07 * 10^{15} m/s^2$

so above is the magnitude of acceleration and its direction is opposite to field as electron is negatively charged so direction is towards SOUTH

Answer:

It's probably the Redshift and Blueshift

Explanation:

The light shifting towards shorter or longer wavelengths as objects in space (stars or galaxies) move closer or farther away from us. This phenomenon is known as the Redshifts and Blueshifts. The concept indicates us that the Universe is expanding.

Hope this helps you!
