Answer:
Because the ping pong ball has a lesser mass than a baseball; hence the ping pong ball will accelerate faster than the baseball when a constant force is applied to both
Explanation:
The force applied to an object is a product of its mass and acceleration i.e. F=ma. According to Newton's second law of motion, the relationship between the mass of an object and its acceleration when force is applied to it was described.
In a summary, the second law states that that the acceleration of an object increases with increased force and decreases with increased mass. This means that the more the mass of an object, the greater the force needed to make it accelerate and also the more the mass, the lesser it accelerates.
In this case, a ping pong ball has a lesser mass compared to a baseball, hence, it will accelerate faster than the baseball assuming an equal force was applied. Since the ping pong ball will accelerate faster, it will hit a person faster than the baseball.
Answer:
The correct option is <u>B. Lipids</u>
Explanation:
Lipids can be described as molecules which dissolve in non-polar solvents and cannot dissolve in water. The biological function of a lipid molecule is to store energy as well as to structure the shape of cell membranes. Lipids are also used in a cell for signalling.
Lipids are made up of carbon, hydrogen and oxygen. Some lipids might have phosphorus in them like the phospholipids which make up the cell membrane.
Answer:
Persuasion
Explanation:
Propaganda is manipulation with public opinion, it is a technique of influencing people’s actions through arguments and persuasion. Propaganda can be done in various ways and some of them are oral, written and visual ways.
As propaganda’s purpose is to convince people in something, techniques used for propaganda are founded on psychological research. People who use propaganda use arguments that don’t have to be valid but have to be convincing.
Answe
Explanation:
Excersice increases the cardiac and skeletal muscels strenght for maximum oxygen consumption for energy output.
It lowers the blood pressure and in prove RBC count for oxygen transportation and distribution.
It cut down risk of osteoporosis, by stimulating bone growth.
Answer:
Balanced Forces
Explanation:
When the forces acting on an object have equal strength and act in opposite directions, they are balanced.When the forces acting on an object are unbalanced, they do not cancel out one another.
