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.
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.
Explanation:
Which substance has a lower coefficient of friction?
sandpaper

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?
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).

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

Answer:
fighting obesity and weight problems in kids remains a serious health concern. More than one-third of American children and teens are overweight or obese, according to the Centers for Disease Control and Prevention. Children with obesity are at higher risk for having other chronic health conditions and diseases that impact physical health. Children with obesity are bullied and teased more than their normal-weight peers and are more likely to suffer from social isolation, depression, and low self-esteem. 2

Lucia has a bedroom window that gets direct sun in the afternoon and her room gets hot. She puts some mylar (a shiny plastic) on the outside of her window.
1. How might this change the temperature in her room? Use what you know about light to explain your answer.
Answer:
Green house effect
Explanation:
Glass panes trap the sunlight which is ultraviolet radiations of low wavelength and after reflection it is converted to heat waves. In the form of heat waves having higher wave length the window panes do not allow them to pass and can't go out of the window pane back so, these trapped heat waves will rise the temperature of bedroom. This effect is known as green house effect.

Explanation:
As we know our atmosphere or air have different levels. 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.
