Answer:
La función del aparato respiratorio es mover dos gases: el oxígeno y el dióxido de carbono. El intercambio de gases tiene lugar en los millones de alvéolos de los pulmones y los capilares que los envuelven
An electric conductor is an element with free electrons in its outer orbit
Answer: For the given process it is true that the balloon has a net charge on it, but the wall may be neutral (have no net charge).
Explanation:
When we tend to rub a balloon against a woolen sweater then it is possible that the balloon might stick to the wall. This might be due to the increase in number of electrons on the balloon and the wall gets positively charged.
Since, opposite charges tend to attract each other hence, the balloon will stick to the wall.
A neutral object also tends to acquire a certain charge when it is rubbed by a charged object.
Therefore, we can conclude that the balloon has a net charge on it, but the wall may be neutral (have no net charge).
the answer you are looking for is the independent variable.
Answer:
4.05 m/s
Explanation:
We shall represent the different velocity in vector form
Newton runs due north at 3.90 m/s, with respect to standing Daniel .
V_n = 3.9 j
Let Pauli runs with respect to standing Daniel with velocity X .
Then relative velocity of Newton with respect to running Pauli will be
3.9 j - X
Give that
relative velocity of Newton with respect to running Pauli = 1.1 i ( 1.1 due east )
So
3.9 j - X = 1.1 i
X = -1.1 i + 3.9 j .
Magnitude of X
X² = 1.1 ² + 3.9²
X = 4.05 m/s
So Pauli runs with respect to standing Daniel with velocity 4.05 m /s .
Direction will be , west of north at angle θ ,
Tan θ = 1.1 / 3.9
