What is the role of the midbrain, and which part of the midbrain is important for arousing the forebrain?
Rainbow [258]

Answer:

The fore-brain consists of the cerebrum, thalamus, and hypothalamus. Mid-brain relays information between fore-brain and hind-brain. Mid-brain plays important role in developing motor functions like eye movement, auditory functions and visual processing.  The crus cerebri connects the cerebral hemispheres to the cerebellum, contains a portion having a network of neurons that is responsible for arousal and alertness.

1. What is the momentum of a 0.15 kg arrow that is traveling at 120 m/s?
Korvikt [17]

For this case we have that by definition, the momentum equation is given by:

p = m * v

Where:

m: It is the mass

v: It is the velocity

According to the data we have:

m = 0.15 \ kg\\v = 120 \frac {m} {s}

Substituting:

p = 0.15 * 120\\p = 18 \frac {kg * m} {s}

On the other hand, if we clear the variable "mass" we have:

m = \frac {p} {v}

According to the data we have:

p = 250 \frac {kg * m} {s}\\v = 5 \frac {m} {s}\\m = \frac {250} {5}\\m = 50 \ kg

Thus, the mass is 50 \ kg

Answer:

p = 18 \frac {kg * m} {s}\\m = 50 \ kg

Your electric drill rotates initially at 5.35 rad/s. You slide the speed control and cause the drill to undergo constant angular
Agata [3.3K]

Answer:

The  angular displacement  is  \theta  =  29.6 \ rad

Explanation:

From the question we are told that

     The initial angular speed is  w =  5.35 \ rad/s

      The angular acceleration is  \alpha  =  0.331 rad /s^2

      The time take is  t =  4.81 \ s

     

Generally the angular displacement is mathematically represented as

          \theta  =  w * t  + \frac{1}{2} \alpha  * t^2

substituting values

         \theta  =  5.35 * 4.81  + \frac{1}{2}  *  0.331  * (4.81)^2

         \theta  =  29.6 \ rad
