As shown in the diagram, the forward thrust of the engine is 85N. The wind and air resistance is providing 100 N of force to the reverse. What is the net force on the airplane?

● 85 N right

● 100 N left

● 185 N right

● 15N left​

As Shown In The Diagram, The Forward Thrust Of The Engine Is 85N. The Wind And Air Resistance Is Providing

Answers

Answer 1
the answer is 15N left. you just have to subtract the 85 from 100 :) hope this helps
Answer 2
The net force in 185 N right because 100 plus 85 is 185

What should a rescuer do if blood is seen in a seizure patient's mouth?

Answers

Answer: i couldn't find anything except these -Protect the person from injury.

Keep him or her from falling if you can, or try to guide the person gently to the floor.

Try to move furniture or other objects that might injure the person during the seizure.

If the person is having a seizure and is on the ground when you arrive, try to position the person on his or her side so that fluid can leak out of the mouth. But be careful not to apply too much pressure to the person's body.

Do not force anything, including your fingers, into the person's mouth.

Do not try to hold down the person. This can cause injury, such as a dislocated shoulder.

Explanation:

Answer:

If Blood is seen in a seizure patient's mouth the best thing a rescuer should do is to lie the patients on his/her side so that the any fluid ( blood inclusive ) can stop flow properly

Seizure is a mental disorder which is caused by an electrical disturbance in the brain of the patient. this electrical disturbance leads to several uncontrollable behavior/movement by the patient. It always very frightening to watch a seizure patient hence we should take absolute care when handling one by observing the following

Make sure not to hold the patient down Protect the patient from every harmful object Do not force your hands into his/her mouth be very close to the patient until the seizure is over seek for the help of a medical personnel .lie the patient on his side to allow the proper flow of fluids

Hence The best thing to do is : lie the patients on his/her side so that the any fluid ( blood inclusive ) can stop flow properly

If a 100 g cart is accelerating down the hill at 5.6 m/sec2, what is the force that is the size of the force causing the acceleration?

Answers

f=ma m=100g=0.1kg
so 0.1•5.6=0.56

The force causing the acceleration of the cart is 0.56 Newtons (N).

The force causing the acceleration of an object can be calculated using Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. Mathematically, it can be expressed as:

Force = mass * acceleration

Given that the mass of the cart is 100 g (which is equivalent to 0.1 kg) and the acceleration is 5.6 m/s², we can substitute these values into the equation to find the force:

Force = 0.1 kg * 5.6 m/s²

Force = 0.56 kg·m/s²

Therefore, the force causing the acceleration of the cart is 0.56 Newtons (N).

A force is simple a ___________ or a _______________.

The SI unit for force is ____________________.

When the net force on an object is not zero newton, the forces are said to be _______________________________.

When 2 forces act in opposite directions, you __________________ (add, subtract) the forces.

Answers

Answer: a force is simply a push or pull.

The SI unit for force is Newton(N) or kgm/s2

When the net force on an object is not zero the forces are said to be unbalanced since they do not cancel out each other .

When two forces act in opposite directions we substract the forces in order to get the resultant force acting on the object.

If the earth didn't have a tilt, we wouldn't have seasons. Instead, the environment would be unchanging, and the temperature would vary upon latitude. Equatorial regions would be constantly hot and humid, and polar regions would always be cold. There would no variability to the climate as the year progresses.

Every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

Add all the net forces together and that number will be your new net force and that’s how it done
If the arrows are in the same direction then you have to add them. If the arrows are in opposite you have to take away. For example for question 5 8-4=4 so thE net force will be 4 and the arrow will be left as 8N is bigger. For question 4 they are in the same direction so you add them it will be 9N to the right. For question 3 they are in opposite so it will be 0 and both arrows are equal so the net force is 0 and then object is stationary
