For added effect, he takes the monitor up to the roof which is about 84 m above the ground. What is the velocity of the monitor as it hits the ground?
The velocity of the monitor as it hits the ground is equal to 40.58 m/s.
Given the following data:
Height = 84 meters.Scientific data:
Acceleration due to gravity (g) = [tex]9.8 m/s^2.[/tex]How to calculate the velocity.In accordance with the law of conservation of energy, the potential energy possessed by the monitor at the roof top would be equal to the kinetic energy possessed by the monitor at the ground:
[tex]PE=KE\\\\mgh=\frac{1}{2}mv^2\\\\2mgh=mv^2\\\\V=\sqrt{2gh}\\\\V=\sqrt{2 \times 9.8 \times 84}\\\\V=\sqrt{1646.4}[/tex]
V = 40.58 m/s.

Without using a micrometer screw gauge, how do I find the average diameter of a long piece of thin wire using a metre rule and a uniform glass rod?
Answer:
Wind the long piece of thin wire around the uniform glass rod multiple times, find the length of the total diameters using the metre ruler, and divide by the number of times you wound it around the rod.
Explanation:
Since the diameter of one long piece of thin wire is too thin to be measured by a metre ruler, you can wind it multiple times and push it side by side to get a length you can measure.
For example, if you wound it around 20 times and the total length of 20 diameters of the wire side-by-side is 2.0 cm, one winding, which is the diameter would be 2.0cm ÷ 20 = 0.10cm or 1mm.
What are the differences between tidal power and hydroelectric power?
Thanks to anyone who helped
Answer: With Hydroelectric power water is artificially stored in a high place, so it can be released and flow to a low place and through a generator. With Tidal energy the movement of water is also used to power a generator, but the flow of water is caused by the changing tides.
During anomalous expansion of water ,heat transfer is limited to conduction and radiation only ,explain.
Heat transfer is limited to conduction and radiation only in anomalous expansion of water simply because of the temperature at which the expansion occurs and density
What is anomalous expansion of water?Anomalous expansion of water is a property of water in which water expands instead of contracting.

Explain your answer.

10. Driving at night offers a great example of diffuse vs. regular reflection. A dry road is a diffuse
reflector, while a wet road is not. On the diagrams below, sketch the reflected light off a wet and dry
surface.
Dry Surface
Wet Surface
Why would the wet road appear to the driver to be darker than the dry road?
11. The diagram below contrasts the reflection of light off a smooth surface (left) with the reflection of
light off a rough surface (right). Compare the two diagrams and explain why the reflected rays for a
rough surface do not result in the formation of an image.
Based on the nature of reflection of light from surfaces, smooth surfaces produce regular reflection while rough surfaces produce diffuse reflection.
What is reflection of light waves?Reflection of light waves refers tobtye bouncing back of light waves when they hit a shiny surface.
Depending on the nature of the surface, reflection of light waves can either be regular if diffuse.
Smooth surfaces produce regular reflection while rough surfaces produce diffuse reflection.
Based on the properties of reflection:
A microscopic view of a sheet of paper shows that the surface is rough, thus it would produce diffuse reflection. Rough pages are easier to read from than smooth and glossy surfaces because they produce diffuse reflection while reading off smooth surface causes a glare due to intense regular reflectionA wet road appears darker because more light passes through and it reflects less light and looks darkerdiffuse reflection do not all pass through the principal focus, thus an image is not formed off a rough surfaceTherefore, it can be concluded that the rough surfaces produce diffuse reflection while smooth and glossy surfaces produce regular reflection.

a roller coaster of mass 2000kg is rolling down a track with an instantaneous speed of 10m/s
The given is:Mass – 2000 kg
The given is:Mass – 2000 kgInstantaneous speed – 10 meter per second
Step: 1Step: 1K.E= 1/2mv^2
Where, K.E – Kinetic energy in joules:
m – Mass in kg
v – Velocity or speed in meter per second
Step: 2From the give,
m = 2000 kg
v = 10 m/s
Equation (1) becomes,
K.E= 1/2 (2000) (10)^2
= (0.5)(2000)(100)
= 100000
K.E = 100,000 Joules
The kinetic energy is 100,000 Joules, if a roller coaster of mass 2000 kg is rolling down a track with an instantaneous speed 10 m/s.

an object from 10.0 meters. She knows it had 50.0 joules of potential energy. How much mass does it have?
Answer:
5N
Explanation:
Work done by a constant force is given by the following equation:
W=F⋅d⋅cos(θ)
where F is the applied force, d is the distance over which the force is applied, and θ is the angle between the force and displacement vectors.
In this case, the work is done by gravity, and as the object is assumed to fall straight down, θ=0^o.
We know that the force of gravity acting on an object can be expressed by FG=mg, and for an object which is not accelerating (e.g. a stationary object), this is equal to the object's weight.
We know d=10m,θ=0^o and W=50J, so we can solve for F to find the object's weight. ⇒F=Wdcos (θ) But cos (0^o)=1, so: F=Wd=50J10m=5N

a car of mass 800 kg is travelling at 12m/s the car accelerates over a distance of 240 m there force causing this acceleration is 200 newton determine the work done on the car and its final velocity car
Answer:
See below
Explanation:
Force X distance = work
200 N * 240 m = 48 000 N-m = 48 000 j
F = ma
200 = 800 a
a = 1/4 m/s^2
d = v t + 1/2 a t^2
12 m/s t + 1/2 1/4 m/s^2 t^2 = 240
shows t = 17 sec (via Quadratic Formula)
final velocity = 12 + at = 12 + 1/4(17) = 16.26 m/s

Describe the rise and fall of a basketball using the concepts of kinetic energy and potential energy.
Answer:
in the beginning the kinetic energy is at a maximum level because the starting velocity is high comparatively.. and because of the gravitational acceleration acting on the ball in the opposite direction the kinetic energy drops proportionally because of the velocity drop. after the ball reaches it's maximum height the potential energy of the ball is high because of the height.. and again the kinetic energy starts to build because the ball again starts to fall down..

A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, and velocity in meters per second on the y axis, numbered 0 to 10. A line starts at (0, 10) and ends at (5, 0).
A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, velocity in meters per second on the y axis, numbered 0 to 35. A curved line starts at the origin and arcs up to (4.3, 35).
The graph in the question that represents an object with constant acceleration is : Graph A
Description of constant accelerationAcceleration is the change in velocity with time. For graph A the acceleration remained constant as the velocity of the object did not change with the change in time. As the time changes from 4 to 9 seconds the velocity of the object remained at 40 before decelerating to 0. This shows that the acceleration of the object was constant.
Hence we can conclude that The graph that shows an object with constant acceleration is : Graph A
