What is the mass of a cylinder of lead that is 2.50 cm in diameter, and 5.50 cm long. The density of lead is 11.4 g/cm3. Volume = h r2 (Show your work)
Density of cylinder = 11.4g/cm3
Volume of cylinder = h r2
but height (h) = 5.50cm
radius(r) = d/2 = 2.50/2 = 1.25cm
Hence Volume = 5.50 × (1.25)2
= 8.6cm3
Density = Mass/Volume
Hence Mass of the cylinder =
Density × Volume
Mass = 11.4 × 8.6 = 94.04g.

what is a beam on a bridge? what does it do?
Answer:
A beam carries vertical loads
Explanation:
In bridge: Beam. The beam bridge is the most common bridge form. A beam carries vertical loads by bending. As the beam bridge bends, it undergoes horizontal compression on the top.
I hope this answered your question, if not let me know :)
In order to lift a lighter object on the other side, a boy placed 155 N of
effort force through a vertical distance of 0.25 m. How far will the lever lift
the lighter object if the resistance distance is 3.5 m from the fulcrum and
the effort distance is 1.5 m from the fulcrum? *
Answer:
0.58 m
Explanation:
In order to find the vertical distance the load lifts, we first need to find the magnitude of the resistance force. So, Rd = Fd' where R = resistance force = ?, d = resistance distance = 3.5 m, F = effort force = 155 N and d' = effort distance = 1.5 m.
So R = Fd'/d = 155 N × 1.5 m/3.5 m = 232.5 Nm/3.5 m = 66.43 N
Now, the vertical work done by the effort = vertical work done by load
Fy = Ry' where y = vertical distance moved by effort = 0.25 m and y' = vertical distance moved by resistance force
So, Fy = Ry'
y' = Fy/R
= 155 N 0.25 m/66.43 N
= 38.75 Nm/66.43 N
= 0.58 m
So, the vertical distance the lighter object moves is y' = 0.58 m

Drag each label to the correct location on the chart. Classify the organisms based on how they obtain food.
Autograph: Trees (Image 1), algae (Image 4), carrots (image 6)
Heterograph: Tiger (Image 2), deer (image 3), human (image 5)
Explanation:
The difference between autotroph and heterotroph organisms is the way they obtain energy. In the case of the first category, these include organisms that can produce energy by a process known as photosynthesis. This covers all plants and similar such as tress, algae, and carrots.
On the other hand, heterotrophic organisms cannot produce energy and need to feed on other organisms, which can include feeding on plants or animals. In this context, this category includes tigers because they feed on other animals, deer because they feed on plants, and humans because we feed on plants and animals.
Answer:
Autograph: Trees (Image 1), algae (Image 4), carrots (image 6)
Heterotroph: Tiger (Image 2), deer (image 3), human (image 5)

When you are stopping your vehicle at an intersection with traffic lights
Answer:
you hit the breakes and wait till the light turns green and then turn on your blinkers im very sorry if this is wrong
Explanation:
:)
At some intersections, the traffic signals has been equipped with the sensors just to detect vehicles, and the traffic signal will only change if a vehicle facing the red traffic light stops at the stop line.
What is a traffic signal?A traffic signal has been refers to the sign that has been erected just beside or above roads by the road safety agency, in order to give warnings and the instructions to road users such as the Driverers, the Passengers, or the Pedestrians.
At some intersections, the traffic signals has been equipped with the sensors just to detect vehicles, and the traffic signal are the programmed to the only change if a vehicle facing the red traffic light stops at the stop line.
Traffic at intersection could be complicated at the times. If the green light comes on after just a red light, you have the right of way to go, but you should be careful to only go when the intersection is clear to avoid an accident.
Therefore, At some intersections, the traffic signals has been equipped with the sensors just to detect vehicles, and the traffic signal will only change if a vehicle facing the red traffic light stops at the stop line.

What is the IMA of this pulley belt system if the diameter of the input
pulley is 2.5 inches and the diameter of the output pulley is 7 inches?
Answer:
2.8
Explanation:
The ideal mechanical advantage of the pulley IMA = D'/D where D' = diameter of output pulley = 7 inches and D = diameter of input pulley = 2.5 inches
So, IMA = D'/D
= 7/2.5
= 2.8
So, the ideal mechanical advantage of the pulley IMA = 2.8
