Two rockets are flying in the same direction and are side by side at the instant their retrorockets fire. Rocket A has an initia

Sedaia [141]

Answer:

$a_2\ =\ -33.65\ m/s^2$

Explanation:

Given,

For the first rocket,

Initial velocity of the first rocket A = $u_1\ =\ 4600\ m/s.$

Acceleration of the first rocket = $a_1\ =\ -18\ m/s^2$

For the second rocket,

Initial velocity of the second rocket B = $u_2\ =\ 8200 m/s.$
Displacement of both the rockets A and B = s = 0 m

Fro the first rocket,

Let 't' be the time taken by the first rocket A for whole the displacement

$\therefore s\ =\ u_1t\ +\ \dfrac{1}{2}a_1t^2\\\Rightarrow 0\ =\ 4600t\ -\ 0.5\times 18t^2\\\Rightarrow t\ =\ \dfrac{4600}{0.5\times 18}\\\Rightarrow t\ =\ 511.11 sec$

Let $a_2$ be the acceleration of the second rocket B for the same time interval

from the kinematics,

$\therefore s\ =\ ut\ +\ \dfrac{1}{2}at^2\\\Rightarrow s\ =\ u_2t\ +\ \dfrac{1}{2}a_2t^2\\\Rightarrow a_2\ =\ \dfrac{2s\ -\ 2u_2t}{t^2}\\\Rightarrow a_2\ =\ \dfrac{0\ -\ 2u_2t}{t^2}\\$

$\Rightarrow a_2\ =\ -\dfrac{2u_2}{t}\\\Rightarrow a_2\ =\ -\dfrac{2\times 8600}{511.11}\\\Rightarrow a_2\ =\ -33.65\ m/s^2$

Hence the acceleration of the second rocket B is -33.65\ m/s^2.

Find the equivalent resistance, the current supplied by the battery and the current through each resistor when the specified res

VLD [36.1K]

Answer:

$R_{eq}$ = 19 Ω, I = 0.105 A, V1 = 1.05 V and V2 = 0.95 V

Explanation:

The correct way to solve this type of problem is to find the current or voltage values for the equivalent resistance and from here find the other values.

For a series circuit the equivalent resistance is the sum of the resistance

$R_{eq}$ = R1 + R2

$R_{eq}$ = 10 +9

$R_{eq}$ = 19 Ω

Let's use the equation for the voltage

V = I $R_{eq}$

I = V / $R_{eq}$

I = 2/19

I = 0.105 A

In a series circuit the current is constant, so let's use the voltage equation for each resistor

V1 = I R1

V1 = 0.105 10

V1 = 1.05 V

V2 = 0.105 9

V2 = 0.95 V

Note that the sum of this voltage is the total voltage applied.

Testable hypotheses that lead to experiments usually describe a relationship between

Harlamova29_29 [7]

a measurable variable and a subjective opinion.

Explanation:

Testable hypothesis that leads to experiments usually describes a relationship between a measurable variable and a subjective opinion.

In testing a hypotheses through experiments, we often design our work to suit the use of two variables which are the measurable variable and the subjective opinion.

This often takes the shape of dependent and independent variables in an experiment.
Measurable variables can either be dependent, independent or controlled variables.
The subjective opinion is the scientific logic that governs hows two or more variables are related.
