A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to.

Answer:

An object can be said to be in motion if there is a change in its initial position relative to a reference point.

Explanation:

A reference point could be a place or something that can be used to determine if an object is in motion relative to it. Thus, the reference point make us to understand the properties (type, distance and direction) of the motion.

Also, motion of any object can be explained using an inertial frame. This frame considers its relative motion with respect to a reference point.

The diagram shows a positive charge moving in a magnetic field. a field of circles labeled b. there is a positively charged part
lesya692 [45]

The magnetic force will be point upwards in perpendicular direction to the field.

<h3>What is the direction of magnetic force?</h3>

The direction of the magnetic force on negative charge occurs in the opposite direction while it is directed to the positive charge direction.

From the given image and description, the positively charged particle with a velocity vector, v is pointing left, thus we can conclude that the magnetic force will be point upwards in perpendicular direction to the field.

1. When human bones are brittle due to eating too much dairy food, what is this called?
Firdavs [7]

Answer:

1. Osteoporosis

2. Dehydration

3. Atherosclerosis

4. Aerobic exercise

5. Heart disease, obesity, diabetes and high blood pressure

6. Coronary heart disease, colorectal cancer, diabetes

Explanation:

1. Osteoporosis is the condition of the bones when they become easily fractured and less dense, such that injuries to the bones are likely to cause disability or pain

2. The bod becomes dehydrated in the event that there is insufficient water for proper functioning of the organs due to the loss of more water than the water that is taken in or absorbed.

3. Atherosclerosis is the building of plaque on the inside and outside of the walls of the arteries by cholesterol, fat, and other compounds in the blood often being taken as a problem or undesirable condition of the heart.

4. Processed foods are those that contain chemicals (that give them a good taste) in proportions that can cause illnesses

5. Taking large quantities of (red) meat such as burgers, or barbecued red meat,  can lead to type 2 diabetes, cancers and stroke
