Answer:
(a) potential energy = 490.5 kg
(b) kinetic energy = 500 kg
Explanation:
Given data in question
total mass (m) = 10 kg
total height (h) = 5 m
average velocity = 10 m/s
To find out
potential energy and kinetic energy
Solution
First we calculate potential energy, and we know formula for potential energy is
potential energy = mass × gravity × height
put the value of mass and height and take gravity force = 9.81
potential energy = 10 × 9.81 × 5
potential energy = 490.5 kg
Now we calculate kinetic energy, and the kinetic energy formula is given below
kinetic energy = 1/2 × mass × velocity²
put the value of mass and velocity
kinetic energy = 1/2 × 10 × 10²
kinetic energy = 500 kg
U can use the area rule formula

Answer:
1/2 or 1:2
Explanation:
first convert speed of compressor to rpms
Compressor speed= w1 = 150 cycles/s= 150 * 60= 9000 rpms
Speed of turbine= w2 = 18000 rpms
gear ratio = N2/N1 = w1/w2
gear ratio = 9000/18000
gear ratio = 1/2
gear ratio = 1:2
Answer:
Technician A only
Explanation:
In order to loosen a bleeder valve, the following steps can be used
Step 1; Break the taper at the bleeder valve base and the corrosion or rusts present on the threads by tapping on the bleeder valve end with a steel hammer
Step 2; Tap the bleeder valve with a 6-point socket or wrench in the clockwise or tightening direction
Step 3; Tap the bleeder valve with the same 6-point socket or wrench in the counterclockwise or loosening direction in order to loosen it
Step 4; Repeat the above steps until the bleeder valve is loose.
