The dimensions of the completed ISS research facility will be approximately 356 feet (109 meters) by 240 feet (73 meters), or slightly larger than a football field. the ISS weighes around 450 tons (408,000 kg), or 450 times the weight of an average car.
Answer:
may I know which language
Experiments and fieldwork
Answer:
D) Number of electrons.
Explanation:
Elements in the same group on the periodic table has the same number of electrons. These electrons are those involved in bonding with other atoms to form compounds.
The force required to push the box upward is 145.3N and the force to pus the box downward is -109.3N
Data given;
- mass = 15kg
- angle = 30 degree
- acceleration = 1.2 m/s^2
- acceleration due to gravity = 9.8 m/s^2
<h3>Force against gravity</h3>
To move the plane upward, the box will move against gravity.

Let's solve for F

<h3>Force towards gravity</h3>
When the force pushes the box down the inclined plane, it moves towards gravity.

The force required to push the box upward is 145.3N and the force required to push the box downward is -109.3N
