B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.
Marysya12 [62]3 years ago

<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.

Mkey [24]

Solar heating is the system composed of a fluid system to move the heat from the collector to its point of usage and a reservoir to stock the heat

<u>Explanation:</u>

The options given here like coal burning uses solid material as the source to heat and to generate energy. Similarly, nuclear power also requires solid particles like atoms or neutrons to strike the moderators forming energy.

In both of these cases, fluid system is present but it is used completely as coolant and to maintain the temperature. Thus, the remaining system that is solar heating has been done for water tanks where the fluid as water is used to move the heat from its collector to its point of usage. Even in solar system it is used as reservoir to stock the heat.

You will measure and record the time it takes the cart to travel certain distances, and then complete some calculations. In the
natka813 [3]

Answer:

Take the measurement of the distance (d) with a meter rule (in meters) and also measure the time (t) of the travel in seconds with a stopwatch.

question: What is the speed of the cart?

Explanation:

The speed of an object in motion is the distance covered by the object with respect to time, that is, the ratio of distance covered to the time taken to reach that distance.

Speed = distance / time

           = d (in meters m) / t (in seconds s) = m/s

If the focal length of a concave mirror is 18cm, find its radius of curvature.
Galina-37 [17]

Given :

The focal length of a concave mirror is 18 cm.

To Find :

The radius of curvature of the concave mirror.

Solution :

We know,

\text{Focal length}=\dfrac{\text{Radius of curvature}}{2}\\\\F=\dfrac{R}{2}\\\\R = 18\times 2\ cm\\\\R = 36 \ cm

Therefore, the radius of curvature of concave mirror is 36 cm.

Hence, this is the required solution.
