B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.
Marysya12 [62]2 years ago
4 0

<u><em>Answer </em></u>

B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.

<u><em>Explanation </em></u>

Acceleration is the rate of change of velocity. It is calculated as follows;

a = (v - u)/t

Where a⇒ acceleration

v ⇒ final velocity

u ⇒ initial velocity

t ⇒ time taken.

<u>For Gabriella; </u>

a = (32-55)/10 = -23/10 = -2.3

Since acceleration is negative, Gabriella was desecration (slowing down.

<u>For Franklin, </u>

a = (50-50)/8.5 = 0

This means no acceleration.

<u>For Kendall; </u>

a = (67-53.2)/6 = 13.8/6 = 2.3

Positive acceleration means, he was speeding up.

From the choices the correct answer is B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.

An object that weighs 2.450 N is attached to an ideal massless spring and undergoes simple harmonic oscillations with a period o
Viktor [21]

Answer:

Spring constant, k = 24.1 N/m

Explanation:

Given that,

Weight of the object, W = 2.45 N

Time period of oscillation of simple harmonic motion, T = 0.64 s

To find,

Spring constant of the spring.

Solution,

In case of simple harmonic motion, the time period of oscillation is given by :

T=2\pi\sqrt{\dfrac{m}{k}}

m is the mass of object

m=\dfrac{W}{g}

m=\dfrac{2.45}{9.8}

m = 0.25 kg

k=\dfrac{4\pi^2m}{T^2}

k=\dfrac{4\pi^2\times 0.25}{(0.64)^2}

k = 24.09 N/m

or

k = 24.11 N/m

So, the spring constant of the spring is 24.1 N/m.

PLS ANSWER ASAP!!
Molodets [167]

b) between poles M1 and M2

Explanation:

From the expression, we can deduce that r is the distance between two magnetic poles M1 and M2.

The law of attraction between two magnetic poles states that:

<em>  the force of attraction or repulsion between two magnetic poles is a function of the product of the strength of the magnetic poles and the square of the distance between the pole</em>s

 

    Mathematically:

            FM = K \frac{M1 M2}{r^{2} }

 here r is the distance between the poles

  FM is the magnetic force between the poles

   M1 is the strength of the first magnetic pole

   M2 is the strength of the second pole

   K is the magnetic field constant
