Because it records speed of the car at a certain time, the independent variable should be time and dependent would be speed or velocity. Since it's taken every second, it would be considered instantaneous velocity, which is D.

The focal length of a lens is inversely proportional to the quantity (n-1), where n is the index of refraction of the lens of th
Ainat [17]

Answer:

46.22 cm

Explanation:

The focal refraction, fr is given by

fr = \frac {c}{(1.572 -1)}  = \frac {c}{0 .572}  

The focal red light is given by

fv = \frac {c}{(1.605 - 1)} = \frac {c}{0.605}

\frac {fv}{fr} = \frac {0.572}{0 .605} = 0.945455

\frac {1}{fr} = \frac{1}{image} + \frac {1}{object} and making fr the subject we obtain

fr = \frac {image * object}{(image + object)} = \frac {24.00 * 55} {(24.0 + 55)} = 16.70886 cm

fv = 0.945455* 16.70886 cm = 15.79747 cm

image = \frac {object * f} {(object - f)} = \frac {15.79747 * 24.0}{(24.0 - 15.79747)} = 46.22222 cm

Therefore, violet image is approximately 46.22 cm

Question 26 suppose that a constant force is applied to an object. newton's second law of motion states that the acceleration of
ololo11 [35]

<span>The answer is 6 kg the mass of the second object. By using Inversely proportional formula it means that (14 kg) (3 m/s</span>²<span>) = M (7 m/s</span>²<span>). Where M is the mass of the second object. For the Newton’s second law of motion formula which is: Force = mass x acceleration, we have:</span>

<span>F = (14 kg) (3 m/s</span>²<span>) = 42 N</span>

 

Therefore:

<span>42 N = M (7 m/s</span>²)

<span>M = (42 N) / (7 m/s</span>²<span>)</span>

M = 6 kg mass of the second object

JulsSmile [24]

Answer:

The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2

a_{1},a_{2}=\frac{a_{1}}{2}

Explanation:

The force of friction and the kinetic force make the law of mass in moving so

F=m*a

F=f_{m}+f_{k}

f_{k1}=u*m1*g

f_{k2}=u*2*m1*g

f_{m}=\frac{1}{2}*m1*v^2

The forces are the same however at the moment to determinate the acceleration

a_{1}=\frac{F}{m}

a_{1}=\frac{F}{2*m}

\frac{F}{m} are constant because they make the same motion however the difference of mass make the acceleration difference
