When it's just sitting alone, high in the night sky, the moon just looks"regular" sized. It's the Ebbinghaus effect
Answer:
0J
Explanation:
Mass of the lump M1 = 1.0 kg, initial velocity of the lump U1 = 2m/s to the right,
mass of the metal sphere M2 = 0.5kg, initial velocity of the metal sphere M2 = -4m/s to the left. using conservation law of momentum;
M1U1 + M2U2 = V (M1 + M2)
(1.0 × 2) + (0.5 × -4) = V (1 + 0.5)
2 -2 = V (1.5)
0 = V (1.5)
divide both side by 1.5
0/1.5 = V 1.5/1.5
V = 0
since final velocity after sticking together of the two masses equals zero then their combined kinetic energy will also equal to zero
1/2 V(M1 +M2)
1/2 ×0 × 1.5 = 0J
Answer:
C. County Children and Youth agencies.
Explanation:
The county children and youth agency is responsible for investigating suspected child abuse, child protective services; and assessing the need for general protective services.
Answer:
Explanation:
Yes, it is possible to <u>break a bone</u> or pull a muscle if a person slips on a ground or ice. Broken bone is very painful and makes it impossible to walk. You would know for sure if that was the case.
Much more common is to <u>pull a muscle or joint</u>. You would still be able to walk, but it would hurt. In any case you do need to talk to the general practitioner that treats your family or the one available at school.
If you go back to intensive physical exercise, like cheerleading, if the pain does not go away in a few days, you might cause more damage that could turn out very serious.
Finally, <em>arthritis </em>is a term that includes a number of conditions that affect joints. Most of the diseases that are included under the umbrella term of arthritis, have a gradual onset and manifest in older age.
