An object is dropped from a 32 m tall building. How fast will it be going when it strikes the ground?
The object will be moving at approximately 25.04 m/s when it strikes the ground.
How to determine the speed at which an object will be moving
To determine the speed at which an object will be moving when it strikes the ground after being dropped from a height, use the equations of motion under constant acceleration.
The acceleration is due to gravity and can be approximated as 9.8 m/s².
The equation that relates the final velocity (v) of the object, the initial velocity (u), the acceleration (a), and the displacement (s) is:
v² = u² + 2as
Given:
Initial velocity (u) is 0 m/s (as the object is dropped).
Acceleration (a) is -9.8 m/s² (negative because it acts in the opposite direction to the object's motion).
Displacement (s) is the height of the building, which is 32 m.
Plug in the values into the equation, we have:
v² = 0² + 2 * (-9.8 m/s²) * 32 m
v² = -2 * 9.8 m/s² * 32 m
v² = -627.2 m²/s²
Take the square root of both sides to solve for v:
v = √(-627.2 m²/s²)
Since we are interested in the magnitude of the velocity, the negative sign is ignored.
v ≈ 25.04 m/s
Therefore, the object will be moving at approximately 25.04 m/s when it strikes the ground.
how did Bourne believe that an object could be made to rise or sink at will?
Explanation:
When an object is placed inside water, an upward force is exerted by water called as buoyant force.
An object will float or sink, this completely depends on the density of object. Also, if the magnitude of gravitational force is more as compared to the buoyant force the object will sink otherwise float.
If the density of substance is more than water, it will sink and if the density of substance is less than water it will float.

1. Describe the differences in the ways the sand castle is changed by an ocean wave and by Dylan stomping on it
A sand castle that was changed by the ocean waves would be slowly taken away from by the waves and would just become a smooth mound of sand. If Dylan stomped on it then it would still have all of the same sand as before but in a different shape. It would also become a mound of sand but it would have all the same sand as before.

Check ALL of the options below which show evidence to support the theory of plate tectonics.
A) Composition of rocks found on the moon
B) Sea-floor spreading
C) Horses live in Asia and North America.
D) Analysis of rocks from mountains on separate continents show they are identical.
E) Fossils of the same animals found separated by oceans.
F) Evidence of glaciers in tropical areas.
Evidence supporting the theory of plate tectonics includes B) sea-floor spreading, D) identical rock formations on separate continents, E) matching fossils across oceans, and F) glacial evidence in tropical areas.
To support the theory of plate tectonics, one must look for evidence that indicates movement of the Earth's plates and their historical configurations. The correct options that show evidence supporting this theory are:
Sea-floor spreading: This is a process by which new oceanic crust is formed at mid-ocean ridges and contributes to the plate movements.Analysis of rocks from mountains on separate continents show they are identical: This suggests that these landmasses were once connected as part of a single continent before being separated by plate movement.Fossils of the same animals found separated by oceans: This indicates that these animals once lived on a single landmass that has since been divided by tectonic activity.Evidence of glaciers in tropical areas: The presence of glacial deposits in regions that are now tropical suggests that continents have shifted from polar to equatorial areas due to plate tectonics.

a plane travels 2.5 km at an angle of 35 degrees to the ground and then changes Direction and travels 5.2 km and an angle of 22 degrees to the ground what is the magnitude and direction of the Plains total displacement
We can solve for the resultant x and y components by using the sine and cosine functions.
resultant x = 2.5 cos 35 + 5.2 cos 22 = 6.87 km
resultant y = 2.5 sin 35 + 5.2 sin 22 = 3.38 km
The resultant displacement is calculated using hypotenuse equation:
displacement = sqrt (6.87^2 + 3.38^2)
displacement = 7.66 km
The resultant angle is:
θ = tan^-1 (3.38 / 6.87)
θ = 26.20°
Therefore the magnitude and direction is:
7.66 km, 26.20° to the ground
A heavy 2.0Kg ball is moving at 10m/s when it is caught. A light 1.5Kilogram ball is travelling at 20m/s when it caught. Which ball required the greater impulse? a) The 2.0kg ball because it is more massive. b) The 2.0kg ball because it had more momentum c) The 1.5kg ball because it was travelling faster d) The 1.5 kg ball because it is more momentum e) The question can’t be answered without more information.
To check impulse you will need more information you will require more data as it was diverse with time. In this question, there are two balls with various mass and speed, along these lines they have diverse force. I will expect you are getting some information about the momentum.
The momentum of ball 1 should be:
momentum 1 = mass₁ x velocity₁
momentum 1 = 2kg x 10m/s = 20kg m/s
The momentum of ball 2 should be:
momentum 2= mass₂ x velocity₂
momentum 2= 1.5kg x 20 m/s = 30kg m/s
The answer would be "1.5kg ball because it was travelling faster".
Answer:
the answer is d
Explanation:
Is it possible for you to take a hike and have the distance you cover be equal to the magnitude of your displacement?
Distance can be equal to displacement ... if the motion is all in a straight line ... but distance can never be greater than displacement.
Yes, it is possible that the distance can be equal to the displacement. a further explanation is given below.
A intervals metric that is taken somewhere across a track could be determined as the Distance, and the measurement of just a specific duration or short timeframe could be considered as a Displacement.Whenever you walk down the road throughout the one manner, the distance, as well as the size of the whole movement, become equivalent or comparable.
Thus the above answer is right.

How does a centripetal force cause circular motion
Answer:
It cause the change in the direction of the motion at every instant of time
Explanation:
When an object is revolving around a fixed point with uniform speed then in that case the acceleration of the object tangential to the path must be zero.
which mean the component of acceleration along the speed of the object at all instant of time will zero or not present because it's speed must remains the same
now since the direction of motion is continuously changing here so we can say that the force must acting here in such a way that will cause the change in the direction of the object
So this force must be perpendicular to the velocity at all instant so that the magnitude of velocity will remain the same while the direction of the velocity will continuously changing
So centripetal force will always act along the center of the path of the object

How do glaciers change the Earth's surface?
Answer:
Waves and glaciers weather and erode the Earth’s surface.
Explanation:
Science
Glaciers are important agents of change on the Earth's surface. They can shape the landscape, provide water resources, and impact global climate patterns.
What is a Glacier?Glaciers are large masses of ice that form over many years from compacted snow in areas where snowfall exceeds snowmelt. As glaciers move, they can have significant impacts on the Earth's surface, including:
(1)Erosion: Glaciers can erode and shape the land as they move. As they flow downhill, they can scrape and grind rocks and soil, carving out valleys and creating features such as cirques, aretes, and u-shaped valleys.
(2)Deposition: As glaciers melt, they deposit sediment they have carried, creating features such as moraines, drumlins, and eskers. These deposits can significantly alter the landscape and create unique features.
(3)Water supply: Glaciers can serve as a source of freshwater for ecosystems and human populations. As they melt, they can provide water for rivers and streams, which can support a variety of plants and animals.
(4)Sea level: Melting glaciers can contribute to rising sea levels, which can have significant impacts on coastal communities and ecosystems.
(5)Climate: Glaciers play a role in regulating the Earth's climate by reflecting sunlight back into space. As glaciers melt, they can reduce this reflective effect, leading to warming temperatures and further melting of glaciers.
Hence, If glaciers melt they have significant impacts like Erosion, Deposition, Water supply, Sea level, and Climate on our earth's surface.
