Heat lost = (75000)(3.77)(3) = 848250 J = heat gained by water
848250 = 400000(4.814)(T)
T = 0.507 C
4 + 0.507 = 4.507 C

Answer:
Simply. It is their wish weather to sit or stand or crul or something
Explanation:
It is their wish to do their work
1. To solve this problem you can use the formula:
Force = mass × acceleration
16 = 5 × a
16/5 = a
3.2 m/sec^2 = acceleration
2. To solve this formula use the same formula that was given above:
F = ma
F= 1239 kg × 4m/sec
F = 4956 N
3. To solve this problem use the formula:
Weight = mass × gravity
W = 35 × 9.8
W = 343 N
4. To solve this problem use the formula:
Momentum = mass × velocity
M = 95 kg × 8 m/s
M = 760 kg × m/sec
hope this helps :)
Answer:
c. The less massive object will have less momentum if the velocities are the same.
Explanation:
p = mv
If the velocities are the same, p ∝ m, so the less massive object will have less momentum.
a. is wrong. If the masses are equal, p ∝ v, so the object with the higher velocity will have the greater momentum.
b. is wrong. If an object has both more mass and a greater velocity, it will have the greater momentum.
d. is wrong. If the velocities are the same, the more massive object will have more momentum.
