What does the volcanoes' tectonic behavior imply?

The creation of an island arc by the volcanoes indicates a converging plate boundary. A diverging plate boundary is shown by the line of volcanoes. Two plates clashing results in faulting and magma formation. These tectonic motions result in earthquakes, mountain formation, and volcanism.

How does the water change when a glacier melts?

Temperature increases cause mountain glaciers to melt, changing the water supply. As the glacier melts, more water first moves lower and away from the glacier. The water supply will be diminished as the glacier retreats, and towns, cities, and farms could lose a significant source of water.

Answers

Area T represents the distance travelled by the object whilst moving at a constant speed. Option (C) is correct.

What is speed?

The distance an object travels in a unit of time is its speed. Speed is a scalar quantity since it has simply magnitude and no direction. SI unit of speed is meter per second.

Hence, mathematically:

Speed = distance travelled/time interval.

Distance travelled = speed × time interval.

In the given graph, area T represents  constant speed × time interval. Hence, area T is equal to the distance travelled by the object moving at a constant speed.

Find A mass of 10 kg is moving in a circular path of radius 2 m with a uniform speed of 50 ms the centripetal acceleration and the corresponding centripetal force​

Answers

Answer:

Centripetal acceleration: [tex]1250\; {\rm m\cdot s^{-2}}[/tex].

Resultant force on the object should be [tex]12500\; {\rm N}[/tex].

(Assuming that the speed of the object is [tex]50\; {\rm m\cdot s^{-1}}[/tex].)

Explanation:

For an object that travels along a circle path of radius [tex]r[/tex] at a speed of [tex]v[/tex], (centripetal) acceleration will be [tex]a = (v^{2} / r)[/tex].

In this example, speed is [tex]v = 50\; {\rm m\cdot s^{-1}}[/tex] while the radius of the circular path is [tex]r = 2\; {\rm m}[/tex]. The (centripetal) acceleration of this object will be:

[tex]\begin{aligned}a &= \frac{v^{2}}{r} \\ &= \frac{(50\; {\rm m\cdot s^{-1}})^{2}}{(2\; {\rm m})} \\ &= 1250\; {\rm m\cdot s^{-2}}\end{aligned}[/tex].

For an object of mass [tex]m[/tex], the resultant force to achieve acceleration [tex]a[/tex] is [tex]F(\text{net}) = m\, a[/tex]. In this example, [tex]m = 10\; {\rm kg}[/tex] while [tex]a = 1250\; {\rm m\cdot s^{-2}}[/tex]. The required resultant force will be:

[tex]\begin{aligned}F(\text{net}) &= m\, a \\ &= (10\; {\rm kg})\, (1250\; {\rm m\cdot s^{-2}}) \\ &= 12500\; {\rm kg \cdot m\cdot s^{-2}} \\ &= 12500\; {\rm N} \end{aligned}[/tex].

What is propagation of wave ?

Waves' progression and transformation through space and time. The article will examine several definitions in addition to the usual one for wave propagation.

There are numerous crests and troughs that sound waves travel over. II Sound waves need a physical medium to travel through. III The movement of particles is thought to be responsible for the propagation of sound waves.

Transverse waves include electromagnetic waves like X-rays, radio waves, and visible light. Electric and magnetic fields moving in a perpendicular direction make up these waves. The best examples of longitudinal waves, which vibrate parallel to the direction of the wave, are sound waves.

The formula is

v = fλ

given distance is 5.45 m

when a wave pulse on a string reflects from a boundary, how is the reflected pulse related to the incident pulse

Answers

The reflected pulse will be equal to or less than incident pulse when wave pulse on a string reflects from a boundary.

A rigid wall causes an object, like a ball, to bounce back when it is thrown against it. In terms of momentum and energy conservation, the object's "reflection" can be examined. The ball will bounce back at the same speed if the collision between the ball and the wall is perfectly elastic and all incident energy and momentum is reflected. The ball does not bounce back with the same speed if the collision is inelastic because the wall (or ball) absorbs some of the incident energy and momentum.Additionally carrying energy and momentum, waves are reflected by obstacles whenever they come into contact with them. Echoes, radar detectors, and standing waves—which are crucial for musical instrument sound production—are all caused by waves that have been reflected.

A vertical spring with mass M that is attached steadily lowers to its equilibrium position. This causes the spring x to lengthen. Suppose the same thing was still tied to the same vertical spring, but it was allowed to fall suddenly instead.

How can you determine a spring's top speed?

The maximum velocity is equal to the amplitude times the angular frequency, or v max=A v max = A, since the sine function oscillates between -1 and +1. The mass is travelling toward x=+A when the maximum velocity occurs at the equilibrium location (x=0).

Probability is related to possibility. Random event generation is the subject of this branch of mathematics. Values ​​range from 0 to 1. Probabilities are built into mathematics to predict the likelihood of certain events.

P(tab A won't fit into slot B) = P (A>B)

Given that, A ≈ N(30,0.5)   B ≈ N(32, 0.8)

V(A-B) = V(A) + V(B) = (0.5)² + (0,8)²

Distance between the masses, r = 0.75 m

The equation for gravitational force is given by,

The temperature rise of the iron is 13.33°C

How to calculate temperature in calorimetry?

Calorimetry is the science of measuring the heat absorbed or evolved during the course of a chemical reaction or change of state.

The heat gained or released during a calorimetry procedure can be calculated as follows:

Q = mc∆T

Where;

Q = quantity of heat (J)m = massc = specific heat capacity∆T = change in temperature

According to this question, a 5kg block of iron with a specific heat capacity of 450 J/kg °C recieves 0.03 MJ of energy. The change in temperature can be calculated as follows:

30,000J = 5 × 450 × ∆T

30000 = 2250∆T

∆T = 30000 ÷ 2250

∆T = 13.33°C

Therefore, 13.33°C is the temperature rise.

The mean weight of 500 college students is 70 kg and the standard deviation is 3 kg. Assuming that the weight is normally distributed, students who weigh between 60 kg and 75 kg is 476.

Answers

It is true that when weights is normally distributed, students who weigh between 60 kg and 75 kg is 476.

Mean is the average of given observations and we can calculate mean by dividing sum of observation by the total number of observation.

A standard deviation shows how much data is dispersed in relation to mean. Low deviation indicates that data are clustered and high deviation means data are scattered.

Mean weight is 70 kg and standard deviation is given 3 kg.

α1 = 75 - 70 / 3 = 1.67

α2 = 60- 70/3 = 3.33

So, P( α2- α1) = 0.9375- (1- 0.9666)

                      = 0.9371

The number = 500 ×0.9371

                     = 467

So, the statement is true.

Static shot -  The camera is stationary and does not move during the shot. This can create a sense of stability and calm.Panning shot - The camera moves horizontally from left to right or vice versa, following the action or moving to reveal a new part of the scene.Tilt shot  - The camera moves vertically up or down, following the action or revealing a new part of the scene.Tracking shot - The camera moves horizontally, vertically, or diagonally while following the action or a moving object.

Note that the different camera motions described above are important because they allow filmmakers to convey mood and emotion, create visual interest, and guide the audience's attention within a scene.

For example, a static shot can create a sense of calm or stability, while a handheld shot can create a sense of intimacy or instability. A panning shot can follow the action and keep the audience engaged, while a zoom shot can draw attention to a specific part of the scene.
