my bad i clicked the wrong question to do sorry i wish i could help but im dumb lol
Answer and Explanation:
If the ant was to crawl 50cm to the right, then come back 30 cm, then the total distance walked would be <u>80cm</u>.
- Combine 50cm and 30cm to get 80 cm.
For displacement, the answer is <u>20 cm.</u>
- When calculating displacement, you use the initial (starting) distance. and subtract that from the final distance, giving you the displacement, or the amount traveled from the starting point to the final point if you were to make a straight line from the starting point to end point. (0 to 50, then back 30 the same direction, so subtract 30 from 50 to get 20)

H, I think. The oil has a lower density than the water, so after the 3 minutes it would float on top of the water.
Free fall without air resistance:
g=9.81 m/s²
t=235 s
h=?
h=0.5*g*t²
h=0.5*9.81*235²
h=270879m =270 km
Answer:
775 grams of ice
Explanation:
Heat loss by patient = heat gained by ice
Heat loss by patient = mass×specific heat capacity×(initial temperature - final temperature) = 62×4200×(40-39) = 260,400J
Heat gained by ice = mass × specific latent heat of fusion of ice = m×336000 = 336000m J
336000m = 260,400
m = 260400/336000 = 0.775kg = 0.775×1000 grams = 775 grams of ice
