lights in one room without turning off the lights in another. What should he do to assure that each room's lights function independently of one another?
Question 21 options:

He should wire each room in series with the next.


He should wire each room in parallel with the next.


He should make sure each room's lights provide the same resistance.


He should wire the room with the most lights directly to the circuit breaker box.

A 62 kg boy and a 37 kg girl use an elastic rope while engaged in a tug-of-war on a friction-less icy surface. If the accelerati
Paraphin [41]

Answer:

The magnitude of the acceleration of the boy toward the girl is 1.31\ m/s^2

Explanation:

It is given that,

Mass of the boy, m_1=62\ kg

Mass of the girl, m_2=37\ kg

The acceleration of the girl toward the boy is, a_2=2.2\ m/s^2

To find,

The acceleration of the boy toward the girl.

Solution,

Let a_1 is the magnitude of the acceleration of the boy toward the girl. We know that force acting on one object to other are equal in magnitude but opposite in direction. So,

F_1=-F_2

m_1a_1=-m_2a_2

a_1=-\dfrac{m_2a_2}{m_1}

a_1=-\dfrac{37\times 2.2}{62}

a_1=-1.31\ m/s^2

|a_1|=1.31\ m/s^2

So, the magnitude of the acceleration of the boy toward the girl is 1.31\ m/s^2

bagirrra123 [75]

Answer:

The normal force is 85,42 N

Explanation:

There is no friction force, therefore there is no relationship between the normal force and the friction.

We can find the normal force using a free body diagram and check the forces that are acting on the sled. The total forces are equal to 0 because there is no movement in the y-axis. The movement exists only on the x-axis.
