Answer:

1: The higher the force applied to the ball, the harder to make a home run because of the third law: every action has a reaction, the reaction is absorbed by the bat.

2:Same equation: F=MA from the second law, if the ball has a higher mass, it will have a higher force.

Explanation:

The third rule, which states that every action has a response, which is absorbed by the bat, makes it tougher to hit a home run the more power is given to the ball.

Explain Newton's law.

Newton's laws of motion are three fundamental physical laws that describe the behavior of objects in motion and how they interact with forces. The laws were first published by Sir Isaac Newton in 1687.

Law of Force and Acceleration - The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. This law is often expressed as F=ma, where F is the net force acting on an object, m is the mass of the object, and a is the acceleration of the object.

Law of Action and Reaction - For every action, there is an equal and opposite reaction. This law states that when one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.

why is earthquake prediction a challenge for scientists​

Answers

Answer:

Reliable predictions require precursors – some kind of signal in the earth that indicates a big quake is on the way. The signal has to happen only before large earthquakes and it has to occur before all big quakes.

Explanation:

Answer:

Plato: Currently, we can’t predict earthquakes. We can only measure their magnitude and location at the time that they occur. The equipment to measure earthquakes needs to be buried deep underground and is very expensive. Scientists haven’t developed an earthquake warning system yet because earthquakes give little warning. So there is no reliable way to predict when an earthquake will hit.

Answers

Answer:

Iceland, and states like Washington DC. , South Dakota, Connecticut, Idaho, New Hampshire, Delaware, North Dakota, Illinois.

Explanation:

Iceland is one of the only places where people live without insects.

The reason why Iceland does not have mosquitos or other insects is its oceanic climate that keeps them away.

The insects freeze 3 times a year, which makes their survival in Iceland impossible.

The other states are not completely insect-free, however, their number is so small that is considered as like they don't exist.

What organelle wouldn’t have a job if the smooth and rough ER didn’t work?

Answers

Answer: The Golgi apparatus.

Explanation: I believe it is the Golgi apparatus as the Rough ER and Smooth ER create proteins and sort them in to piles before sending to the Golgi apparatus to deliver.

The Smooth ER and Rough ER are like the suppliers while the Golgi apparatus is like the transporter.

Remember: Proteins have many functions and are needed severely to perform those actions that without the Golgi apparatus, those proteins wouldn’t be able to be transported.
