Answer:
A switch
Explanation:
Without switch the current cannot flow and hence, circuit cannot be activated.
Answer:
The maximum height to which water could be squirted with the hose is 13.380 meters.
Explanation:
A line of current of a fluid can be explained sufficiently by Bernoulli's Theorem. In this case, the system can be simplified due to neglectance of changes in absolute pressure. Water is squirted with an initial speed and reaches its maximum height, where final speed is zero. That is to say:
Where:
, - Initial and final height of water, measured in meters.
- Gravitational acceleration, measured in meters per square second.
, - Initial and final speed of water, measured in meters per second.
If , , and , then:
The maximum height to which water could be squirted with the hose is 13.380 meters.
Answer:
Height as seen by the professor = 38.2 m
Explanation:
Angle of throw = θ = 69°
Velocity of throw = v
X component of velocity = v₁ = v cos 69 = 0.3584 v m/s
Vertical component of the velocity = v₂ = v sin 69 = 0.9336 v m/s
v₂ / v₁ = tan 69 = 2.605
v₂ = 2.605 v₁.
Professor sees as if the x component of velocity =0
v (as seen by professor) + v' = 0
=> v as seen by professor = -v' = -10.5 m/s
This shows that y component of the ball's velocity is 2.605 times its x component of velocity.
with respect to the professor, there is only y component of velocity.
v₂' =v₂ = 2.605 ( -10.5) = 27.4 m/s.
Height as seen by the professor = (27.4)² / 2(9.8) = 38.2 m
Answer:
The DNA in bacteria exists as unpacked blobs.
The DNA in animals and plants are neatly packed.
<h3>EXPLAMATION :</h3>
I don't really have an explanation.
The DNA in animals and plants are neatly packed into chromosomes, whereas the DNA in bacteria exists as an unpacked blob in the cell
Answer:
well, hydropower is using fast-running water as a source of power to power machines or produce electricity, and using water can help make the earth a little cleaner, just like solar energy (energy from the sun). instead of using things like coal, oil, gas which is bad for the earth
