Answer:
19 elements
Explanation:
1 carbon + 12 hydrogen + 6 oxygen = 19
Answer:
Ultrasound is used by bats to navigate (move) and catch prey. Ultrasonic squeaks are produced by bats. These squeaks ponder prey and then return to the bat's ear. This provides bats with information about the location of prey, allowing them to catch it.
Explanation:
Power is defined as the rate of doing work or the work per unit of time. The first step to solve this problem is by calculating the work which can be determined by the equation:
W = Fd
where:
F = force exerted = ma
d = distance traveled
m = mass of object
a = acceleration
Acceleration is equivalent to the gravitational constant (9.81 m/s^2) if the force exerted has a vertical direction such as lifting.
W = Fd = mad = 63(9.81)(7) = 4326.21 Joules
Now that we have work, we can calculate power.
P = W/t = 4325.21 J / 5 seconds = 865.242 J/s or watts
Convert watts to horsepower (1 hp = 745.7 watts)
P = 865.242 watts (1hp/745.7 watts) = 1.16 hp
Explanation: Technically the speed is an inch a second.
Answer:
The potential energy increases and the kinetic energy decreases
