Hello!
Use the formula:
M = k * p
Data:
M = Mechanic energy
k = Kinetic energy
p = Potencial energy
Descomposing:
M = (0,5*mv²) + (mgh)
Replacing:
M = (0,5 * 59,6 kg * (23,4 m/s)²) + (59,6 kg * 9,81 m/s² * 44,6 m)
M = 16317,28 J + 26076,54 J
M = 42393,82 J
The mechanic energy is <u>42393,82 Joules.</u>
Answer:
36.408cm3
Explanation:
Since we acknowledge that density is d= m/v, once we switch it up to maintain v as the number to be found it will change to v=m/d. Therefore, 275.32/7.562 is 36.408 and the unit is cm cube!
Hope that helped!!
The water molecules expand. When anything heats up, molecules spread further apart.
Answer:
5.96 minutes
Explanation:
Two RSM students are standing 20ft
Speed of one student = 300 ft/min
Speed of other student = 200 ft/m
Time they run till they reach a distance of 3000 ft = x
Distance = Speed × time
∴ Time taken to reach a gap of 3000 ft is 5.96 minutes.
