Answer:
mass- the amount of matter in an object
balance- tool used to measure mass
scale- a tool used to measure weight
weight- the downward pull on an object due to gravity
Answer:
Yes
Explanation:
When an object has more mass it takes more gravity to keep it down therefore producing friction which in return reduces the amount of kinetic energy created. A change in an object's speed has an greater effect on its kinetic energy. than a change in its mass has, because kinetic energy is proportional to.
Answer:
Explanation:
Let the linear charge density of the charged wire is given as
here we can use Gauss law to find the electric field at a distance r from wire
so here we will assume a Gaussian surface of cylinder shape around the wire
so we have
here we have
so we have
The question is whether the statement is true or false.
The answer if false.
Explanation:
It is exactly the opposite. The soccer ball will hit the ground with greater velocity.
Since the soccer ball is thrown upward, when it returns to the same heigth from which it was throwm it will have a velocity downward, which will make that the soocer ball reaches the ground at the bottom of the clif with greater velocity than the volleball.
The greater the velocity with which the soccer ball is thrown upward, the greater its velocity when reaches the same point from which it was thrown, and the greater the velocity with which it will hit the ground at the bottom of the clif.
Answer:
1. Belize has a high birth rate and a low death rate.
2. Belize will have a rapidly growing population over the next twenty years.
Explanation:
Belize has a high birth rate and a low death rate. Belize is in the phase II of the demographic transition model. Their population is growing exponentially. This is due to lowering death rates while the birth rates are still high.
Belize will have a rapidly growing population over the next twenty years. When the age structure diagram has a wider base than the middle or top age groups, this indicates a population that is rapidly growing. Belize is early in the transition model and still has high birth rates. Countries like Belize typically have lower opportunities for education for women of reproductive age, can have high infant mortality, and can have high emigration rates.
