Answer:
At Convergent Boundaries:
Subduction
Island arcs
Volcanic mountains
At Divergent Boundaries:
Mid-ocean ridges
Rift valleys
Plates pulling apart
Magma breaks through crust
Magma flows from cracks
Explanation:
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.
Divergent boundaries occur in the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.

If 400j of work is done on an object in 8 seconds, how much power does the object experience?
50w
45W
60W
408
Answer:
50w
Explanation:
Power is equal to Energy divided by Time
∆E/t
Answer:
50 W
Explanation:
Power can be found using the following formula.
p=w/t
where w is work and t is time.
400 Joules of work is done on the object in 8 seconds. Therefore,
w= 400 J
t= 8 s
Substitute these values into the formula.
p=400 J/ 8 s
Divide 400 by 8
p=50 J/s
Add appropriate units. In this case, power uses Watts, or W. (1 Joule per second, or J/s is equal to 1 Watt, or W)
p= 50 W
The object experiences 50 Watts of power
pls help quickly average velocity = u+v/2 or displacement/ total time taken
Answer: Average velocity = u+v/2
Explanation: The definition of velocity is displacement over time taken. That is,
Velocity = displacement/ time taken
But we have initial velocity U and final velocity V. When we are talking about average, we are talking about the mean value of the given parameters.
Therefore, average velocity will be addition of initial velocity and final velocity divided by 2. That is,
Average velocity = (U + V)/2
hi:) anyone able to explain why it’s easier to lift something on moon compared to earth? thanks:)
Because the moon has much less mass than the Earth has. This makes the gravitational forces between the moon and any object much less than the forces between the Earth and the same object, when the object is the same distance from the center of the moon or the Earth.
To talk about an actual number, we usually talk about being on the surface of the Earth or the moon:
A person or object on the surface of the moon weighs about 17% as much as he/it weighs on the surface of Earth. That's about one-sixth as much. So naturally, it's easier to lift something on the moon than it is to lift the same thing on Earth, because when it's on Earth, it's about six times as heavy.
The electromagnetic waves with the most energy have the greatest
period
b) wavelength
c)
frequency
d) color
Frequency is the amount of times the particle moves back and forth per second, more or less. The more energy, the higher the frequency. At the same time, the more energy means you'll have a shorter wavelength (aka period). Color only applies to the visible spectrum.
Answer:
frequency
Explanation: The greater the number of waves appear the greater the energy. The smaller the number of waves appear the lower the energy.
Frequency is the number of times waves appear.

A frictionless roller coaster (22kg) is at a height h traveling with a speed v0 = 10m / s. Assume that h = 20m. The speed of the car at point B is:
Answer:
3 g
Explanation:
An airplane flies 40km directly south in 10 minutes and 20 km directly east in five minutes, its average speed is:
a)2.98km/min
b)2km/min
c)8km/min
d)4km/min
Answer:
D. 4km/min
Explanation:
Since the question deals with "speed" and not "velocity", the direction does not matter.
the plane covers 40 + 20 km=60km in 10mins +5 mins=15mins
60 km - 15 mins
1min- 60÷15= 4 mins
therefore, your answer is D. 4km/min

A horizontal force of 50 N is applied to the object.
Answer:
Mass of object (m) = 5.102 kg
Explanation:
Given:
Horizontal Force (F) = 50 N
Find:
Mass of object (m) = ?
Computation:
We know that, acceleration due to gravity (g) = 9.8 m/s²
⇒ Horizontal Force (F) = mg
⇒ 50 N = m (9.8 m/s²)
⇒ Mass of object (m) = 50 / 9.8
⇒ Mass of object (m) = 5.102 kg
Mass of object (m) is 5.1 kg (Approx)

On February 6, 1971, Alan Shepard made history by becoming the first astronaut to play golf on the Moon. Using only one hand to swing the club because of his bulky space suit, Shepard still managed a long drive. Given the lack of an atmosphere on the moon and a gravitational acceleration of 1.6 m/s2, how far would the shot go with an initial velocity of 25 m/s and a launch angle of 35∘?
A. 367 m
B. 375 m
C. 382 m
D. 391 m
Answer:
Horizontal distance travelled by the ball.
A. 367m
Explanation:
Projectile motion is a motion in which an object moves in a parabolic path due to the action of gravity on it. Projectile motion only occurs when there is one force which is applied at the beginning, after that the only interference is from gravity. e.g the path of a golf ball after hit by a golfer.
Range of the projectile can be defined as the horizontal distance given by the ball. We need to find Range in this question.
The Range of a projectile is given by:
[tex]R = \frac{v^2\cdot{sin2}\theta}{g}[/tex]
where
v = initial velocity = 25 m/s
θ = 35°
g = 1.6 m/s²
Substitute the values in formula of R:
[tex]R= \frac{(25)^2\cdot{sin(2\cdot35)}}{1.6}\\R= \frac{(625)\cdot{sin(70)}}{1.6}\\R=367m[/tex]

Which statements accurately describe the motion map?
Check all that apply.
-The objects are moving in the same direction
-The objects are moving in opposite directions.
-Object A has a greater velocity than object B.
-Object B has a greater velocity than object A.
-Objects A and B have the same velocity
Answer: B & D
Explanation:
The objects are moving in opposite directions is the statements accurately describe the motion map, therefore the correct answer is option B
What is displacement?An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.
It is a vector quantity to be displaced. This means that it is visually represented as an arrow that points from the starting position to the ending position and that it has both a direction and a magnitude.
The total distance traveled by an object is different than the total displacement covered by it because the displacement is a vector quantity and it is calculated on the basis of the shortest distance traveled by the body or object.
Thus, The objects are moving in opposite directions is the statements accurately describe the motion map, therefore the correct answer is option B

Answer:
A long handle
Explanation:
A spanner is basically a wrench, you would also want to use a long handled wrench in order to have more mechanical advantage and be able to apply more torque. This can be proven as well using a simple physics formula:
[tex]t = fd[/tex]
where the variables are:
t = torque
f = applied force
d = perpendicular distance from fulcrum to where the force is applied
It is clear that keeping the applied force constant, if you enlarge the perpendicular distance, d, you will be able to apply more torque and therefore have an easier time releasing this nut.

A. Speeding and highway hypnosis
B. Fatigue and visual effects
C. Velocitation and fatigue
D. Velocitation and highway hypnosis
Answer:
Explanation:
Special problems: Rural areas can be twice as dangerous as their city counterparts. ... Two common effects of driving on open highways are velocitation and ... Avoid speeding on rural roads or after you exit the freeway by checking your ... for a long period of time, be aware of a condition known as "highway hypnosis".
Driving on wide highways frequently results in velocitation and tiredness. The phenomena of accidentally raising speed on roads as a result of repeated exposure to greater speeds is known as velocitation.
It happens when drivers become acclimated to the faster speeds and may unintentionally go over the speed limit, endangering their safety.
Another frequent impact is fatigue, which can occur as a result of extended lengths of repetitive driving on wide-open highways. Fatigue can make it difficult to focus, respond quickly, and make decisions, which makes accidents more likely.
Despite the fact that highway hypnosis and visual effects can also happen when driving, open roads are uniquely linked to velocitation and weariness.
