Answer:
Efficiency of machine=4.9
Explanation:
We are given that
Mass of load=100 kg
Effort=20 N
Velocity ratio=10
We have to find the efficiency of machine.
Load=
Efficiency=
Using the formula
Efficiency of machine=
Efficiency of machine=
Efficiency of machine=4.9
Answer:
Vrel_jon's = 15 [m/s] to the right
Explanation:
Relative velocity is defined as the relative motion between two bodies, taking into account the directions of motion.
Relative velocity is defined as the relative motion between two bodies, taking into account the directions of motion. The relative velocity is defined as the algebraic sum of the velocities, if the movements are opposite the vectors are subtracted, as will be done below.
Vrel = 20 - 5 = 15 [m/s]
A person watching Jon sees him moving to the right at a speed of 15 [m/s]
Answer:
The sympathetic nervous system _____decelerates_______digestion and __accelerates___________blood pressure. See the explanation below, please.
Explanation:
The sympathetic nervous system together with the parasympathetic make up the autonomic nervous system. The sympathetic system acts in situations of stress, prepares the body for "fight or flight", increases heart rate and blood pressure at the cardiovascular level, at the digestive level it slows down the system, produces bronchodilation, pupil dilation (mydriasis).
Answer:
The distance reached is 14.3 m.
Explanation:
To find the distance reached by the diamond first we need to find the flight time:

Where:
h: is the height = 10m
g: si the gravity = 9.81 m/s²

Now, we can find the distance reached:

Where:
is the initial horizontal velocity = 10 m/s

Therefore, the distance reached is 14.3 m.
I hope it helps you!
