MAVERICK [17]

Answer:

The correct answer is option d, that is, endocytosis.

A procedure in which a component gains entry within the cell without getting passed through the cell membrane is termed as endocytosis. In this process, the cell captivates the substances from the external of the cell by engulfing and combining them with its plasma membrane.  

The process is further differentiated into three distinct kinds. These are phagocytosis, pinocytosis, and receptor-mediated endocytosis.

What is the measured output force of a pulley system if the Mechanical Advantage is 0.48 and measured input force is 10N?
Ksenya-84 [330]

Answer:

Output force is 4.8 N

Explanation:

A pulley is a simple machine made of a grooved wheel with a rope or cable wrapped around it. Pulleys are used in the transmission of energy or motion.

The input force is also known as the applied force while the output force is the force exerted on an object by a simple machine.

The mechanical advantage of a pulley is the ratio of the output force to the input force.

Mechanical advantage = output force / input force

Substituting:

0.48 = output force / 10

Output force = 4.8 N
