Answer:C: multiply the input force

Explanation:

A lever is a simple machine consisting of a bar pivoted or supported at a point (known as Fulcrum) about which it can rotate to perform the task.

Mechanical Advantage MA = \frac{E}{L}=\frac{F_{L}}{F_{E}}

where E→ length of effort arm from the pivot

         L→ length of load arm from the pivot

         F_{E}→ force on the end of effort arm

         F_{L}→ force on the end of load arm

<u>By the law of conservation of angular momentum:-</u>

F_{E}\times E=F_{L}\times L

A 0.30-kg object is traveling to the right (in the positive direction) with a speed of 3.0 m/s. After a 0.20 s collision, the ob
andre [41]

Answer:

I = -2.1 kg.m/s

Explanation:

Given,

mass of the object,m = 0.30 Kg

initial speed, v_i = 3 m/s

time of collision = 0.20 s

final speed, v_f = -4 m/s

Impulse = change in momentum

I = m (v_f-v_i)

I = 0.30\times (-4-3)

I = -2.1 kg.m/s

Hence, impulse of the object is equal to I = -2.1 kg.m/s

katovenus [111]

Answer: ​Wernicke's aphasia

Explanation:

John recently suffered a blow to his head. Since then, he finds it difficult to comprehend what others say to him. He also finds it difficult to express his thoughts and cannot seem to find the right words to say while speaking. However, he can speak freely with proper syntax. In this scenario, John is most likely suffering from Wernicke's aphasia.

Wernicke's aphasia occurs when the leftward side of the middle of the brain is damaged or has been altered. An individual who suffers from Wernicke's aphasia will have difficulty in speaking in meaningful and coherent sentences or may have difficulty in understanding the speech of others.
