Creatine phosphate can supply the energy needs of a working muscle at a very high rate, but only for about 8–10 seconds.
Answer:
1 : 2 cm/km or 
One cm represents 2 km.
Explanation:
If 3 cm represents 6 km on the earth, the ratio to consider is: 3 : 6 cm/km which is the same as:
1 : 2 cm/km or 
One cm represents 2 km.
Mammals are endothermic vertebrates
Have hair and fur on the body
Have mammary glands
Four chambered hearts
Have sebaceous (fat secreting glands), sudoriferus (sweat), and scent glands.
Have heterodont dentation (different types of teeth)
Posses diaphragm
Posses one single jaw bone
Have three small bones in the middle of the ear
Answer:
Explanation:
A. The kinetic energy is the same as the initial potential energy:
PE = mgh = (215 N)(2.0 M) = 430 J
__
B. The velocity achieved by falling from a height h is given by ...
v = √(2gh)
v = √(2·9.8 m/s^2·2 m) = √(39.2 m^2/s^2)
v ≈ 6.26 m/s
Answer:
The prediction for its maximum potential energy is 109,375 J
Explanation:
Given;
mass of the coaster car, m = 350 kg
speed of the coaster car at the lowest point, v = 25 m/s
The coaster car will have maximum kinetic energy at the lowest point and based on law of conservation of mechanical energy, the maximum kinetic energy of the coaster car at the lowest point will be equal to maximum potential energy at the highest point.



Therefore, the prediction for its maximum potential energy is 109,375 J
