Answer:
0.667 grams per cm cubed
Explanation:
the formula for density is mass divided by volume
Answer:
0 degrees
Explanation:
Let 
are two forces. The resultant of two forces acting on the same point is given by :
Where 
is the angle between two forces
When 
i.e. when two forces are parallel to each other,
When 
i.e. when two forces are parallel to each other,
When 
i.e. when two forces are parallel to each other,
It is clear that the resultant of two forces acting on the same point simultaneously will be the greatest when the angle between them is 0 degrees. Hence, this is the required solution.
Answer:
Clouds are made up of tiny water droplets. ... As more and more droplets join together they become too heavy and fall from the cloud as rain. Warm air can hold more moisture than cool air. When the warmer air is cooled and the moisture condenses, it often rains more heavily.

Answer:
Curl up test.
Explanation:
The curl up test is done to check the strength of the abdomen muscles and the stability of the core muscles. The strength of the core muscles determines the stability of the body.
The curl up test is done to test the abdomen strength and endurance and the strength of the back muscles.
The test requires the following materials: A flat cushioned surface(clean) and a measuring strip
- The measuring strip is placed on the mat under the students legs so that their fingertips are just resting on the nearest edge of the measuring strip. The feet cannot be held or rest against an object. Keeping heels in contact with the mat, the student curls up slowly, sliding their fingers across the measuring strip until the fingertips reach the other side, then curls back down until their head touches the mat. There should be 20 curl-ups per minute
