Answer:

6.98 × 10^(14) Hz

Explanation:

wavelength in air; λ_o = 430nm = 430 × 10^(-9) m

Speed of violet light in the prism; v = 2 × 10^(8) m/s

Speed of light in air = 3 × 10^(8) m/s

To get the frequency, we will use the relationship;

f = c/λ_o

Plugging in the relevant values;

f = (3 × 10^(8))/(430 × 10^(-9))

f = 6.98 × 10^(14) Hz

aksik [14]

Answer:C) car X

Explanation:

Given

All the cars have identical Engine thus Force Produced by car X will be equal to Y and Z

and $Force=mass\times acceleration$

Since Car X is most massive so acceleration associated with it will be minimum

acceleration of car X is minimum thus it will travel farthest

An Elephant is pulled by a group of clowns across a circus. The elephant has a mass of 1000kg and the clowns are pulling with a

ycow [4]

Answer:

Acceleration = 0.2m/s²

Explanation:

Given the following data;

Mass = 1000kg

Force = 200N

To find acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

$F = ma$

Where;

F represents force.

m represents the mass of an object.

a represents acceleration.

Making acceleration (a) the subject, we have;

$Acceleration (a) = \frac{F}{m}$

Substituting into the equation;

$Acceleration (a) = \frac{200}{1000}$

Acceleration = 0.2m/s²
