If you wanted the laser to refract less as it exits the prism, you should increase the wavelength of the light.

Refraction can be defined as a phenomenon which describes a change (bend) in the path taken by light when it's at surfaces between different transparent materials.

According to the model of light wave, the refraction of light is inversely proportional to its wave. Thus, you should increase the wavelength of light, if you want the laser to refract less as it exits the prism.

One bulb burning out in a series circuit breaks the circuit. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and the last one will still function.

Explanation:

Acceleration is a vector quantity which is defined as the rate at which an object changes its velocity

Given ,

Mass of the body (m) = 200g

Amplitude (A) = 20mm

Maximum force (F) = 0.6 N

Maximum velocity (vmax) =?

We know that

Fmax = mv2max/A

or , 0.6 = 200×10-3xv2max/20×10-3

or , 0.6×20/200= v2max

or , vmax = 0.24 m/s

∴ Maximum velocity = 0.24 m/s2

The value of maximum velocity will be 0.3464 m/s². Energy or work is equal to the product of force and displacement.

The change of distance with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.

The given data in the problem is

Mass of the body is,(m= 200g)

Amplitude is,(A  =20 mm)

Maximum force is,F= 0.6 N

To find;

Maximum velocity

Energy or work is equal to the product of force and displacement.

[tex]\rm KE = \frac{1}{2} mV_{max}^2 \\\\ \rm F_{max} \times A = \frac{1}{2} mV_{max}^2 \\\\ F_{max}= \frac{1}{2}\frac{ mV_{max}^2}{A} \\\\ 0.6= \frac{1}{2}\times \frac{ 0.2 \times V_{max}^2}{20 \times 10^{-3}} \\\\ V_{max}=0.3464 \ m/sec^2[/tex]

Hence,the value of maximum velocity will be 0.3464 m/s².

Answer:

The correct answer is - C.  Increasing the concentration increases the reaction rate.

Explanation:

Answer:

B. Increasing the temperature increases the reaction rate.

Explanation:

The reaction time column displays how long the reaction ran for. If a reaction rate was fast then time taken for reaction to run would be slow right?

Therefore, original condition had reaction time of 10 second, but increaseing temperature lowered the time to 5 second, which must mean that reaction rate increased.

Explanation:

A projectile is shot with the initial speed, it follows the motion called projectile motion. The height of the cliff is 44.91 m.

The speed at the start of the motion is the initial speed.

The horizontal distance is

x = v₀ sin θ. t

Substitute 26.5 for θ, 24 for x and 8.94 m/s for x, we get the time taken to complete the journey.

t = 24/ (8.94 cos26.5) = 3 s

Maximum height reached

H = v₀²sin²θ/2g

H = (8.94)² x sin²( 26.5) /(2 x 9.8)

H =0.8118 m

The height of the cliff is obtained by the equation of motion

0.8118 - h = -1/2 gt² +v₀sinθ.t

Substitute the values, we get

h =0.8118 +1/2x9.8x (3)²

h =44.911m

Thus, the height of the cliff is 44.91 m.

Answer:

√ ae/ ap = √ mp/me 1/2

Explanation:

Mass of the electron = M (Given)

Mass of the proton = M (Given)

Time = t (Given)

But acceleration of electron, ae =FE/me whereas

acceleration of proton, ap = FE/mp

S = 1/2at²1 = 1/2apt²2

t2/t1= √ ae/ ap

t2/t1= √ ae/ ap = √ mp/me 1/2

Answer:

Correct option is D) …

Explanation:

For electron t1​ (small 1) = [tex]\sqrt{ \frac{2S}{ae}[/tex] (small e)

For protion, t2 (small 2) = [tex]\sqrt \frac{2S}{ap}[/tex] (small p)

or [tex]\frac{t2}{t1}[/tex] = [tex]\sqrt\frac{ae}{ap}[/tex] = [tex]\sqrt\frac{eE}{me} *\frac{mp}{eE}[/tex]

= [tex]\sqrt\frac{mp}{me}[/tex]

When a lens in the path of a beam of parallel rays causes the rays to diverge after refraction, it is referred to as a diverging lens.

It always creates a virtual image and has a thinner core than its boundaries.

Concave lenses(diverging lenses) function as diverging lenses because they cause light rays to diverge as they pass through them.

Therefore, when used with air as the operating medium, a concave lens can be thought of as a diverging lens.

The concave lens has several applications, including in telescopes, cameras, lasers, glasses, binoculars, and other optical devices.

The distance traveled by the object in the first 1 second is determined as 0.98 m.

The distance traveled by the object is calculated as follows;

F - μkmgcosθ = ma

0 - μkmgcosθ = ma

- μkgcosθ = a

-(0.4)(9.8)cos60 = a

- 1.96 m/s² = a

s = ut + ¹/₂at²

s = 0(1) + ¹/₂(-1.96)(1)²

s = -0.98 m

|s| = 0.98 m

Thus, the distance traveled by the object in the first 1 second is determined as 0.98 m.
