Answer:

6.7

Explanation:

Answer:

Taking it was dropped with inital velocity of 0m/s.

v = u+at

v = 0 + 9.8*1.5

v = 14.7s

(a=9.8m/s^2 << That's the acceleration due to gravity)

Explanation:

Answer:

The height of the building is approximately 156.58 m

Explanation:

The mass of the ball dropped from rest from the building top = 0.660 kg

The time in which the ball falls, t = 5.65 seconds

The height, h, of the building is given from the following equation of motion;

h = u·t + ¹/₂·g·t²

Where;

u = The initial velocity of the ball = 0 m/s

g = The acceleration due to gravity = 9.81 m/s²

Plugging in the values, we have;

h = 0 × 5.65 + ¹/₂ × 9.81 × 5.65² ≈ 156.58 m

The height of the building, h ≈ 156.58 m.

Answer:

C. The rate of dissolving may be fast or slow.

Explanation:

When a solute is added to a solvent, the rate of dissolving may be fast or slow. This is determined by the temperature of the solvent.

A high temperature of solvent can cause an increase in the rate of dissolving a solute or substance in it, while a low temperature of solvent causes a decrease in the rate of dissolving a solute or substance in a solvent.

Therefore, the rate of dissolving may be fast or slow.

Answer:

Velocity

Explanation:

If the position-time graph of the motion of an object is a straight line, it would mean that the object is moving uniformly. The velocity or the slope of the object is constant in such case. If the slope is curved line, it means that the velocity is not constant.

Hence, the correct option is (c).

Answer:

14.4m/s

Explanation:

To calculate the final velocity (V), we use the formula:

v = u + at

Where; v = final velocity (m/s)

u = initial velocity (m/s)

a = acceleration (m/s²)

t = time (s)

According to the provided information in this question, v = ?, u = 0m/s, a = 1.8m/s², t = 8s

Hence, v = u + at

v = 0 + (1.8 × 8)

v = 0 + 14.4

v = 14.4m/s

Therefore, his final velocity at the end of those 8 seconds is 14.4m/s.

Answer:

1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.

2) The decomposition of radioactive elements causes heat in the interior part of the Earth

3) Heat slowly rises to the mantle and creates convection current.

4). Heat moves to the core

5) The process repeats as cycle.

Explanation:

Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .

The process of mantle convection start with

1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.

2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding

3) Heat slowly rises to the mantle and creates convection current.

4). Heat moves to the core, cools down by conduction and convection of heat.

5) The process repeats as cycle.

The proper and correct arrangement of events in the mantle convection process are:

1. The decomposition of radioactive elements causes heat in the interior part of  the Earth.

2. Heat moves to the core

3. Heat slowly rises to the mantle and creates convection current.

4. Lithospheric plates move in the asthenosphere due to rising and sinking of  materials.

5. The process repeats as a cycle.

Convection is considered to be one of the most efficient ways through which heat is transported from the interior of planet Earth to the surface.

Mantle convection can be defined as the very slow transfer of heat due to the movement of Earth's solid silicate material within the mantle.

Basically, the slow creeping of the mantle causes a transfer of heat from the white-hot core to the brittle lithosphere during mantle convection.

Furthermore, the heating of the mantle takes place from below (the core) and it rises upward in hotter regions while it sinks down in colder regions.

The proper and correct arrangement of events in the mantle convection process are:

1. Heat is caused in the interior part of  the Earth due to the decomposition or decay of radioactive elements.

2. Heat moves to the core.

3. Heat slowly rises from the Earth's core to the mantle and creates convection current in the asthenosphere, which is the plastic layer of the mantle.

4. Lithospheric plates move in the asthenosphere due to rising and sinking of  materials.

5. The process is then repeated as a cycle.

Explanation:

Answer: Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events. The scope and application of measurement are dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioural sciences, measurements can have multiple levels, which would include nominal, ordinal, interval and ratio scales.

Explanation:

Answer:(0,2)

Explanation:

Take origin (0,0) as point A and when you move one block east to point B then coordinates becomes (1,0)

Now you move 4 blocks north to point C then the coordinates of point C becomes (4,1)

Similarly, You move 1 block west to point D such that its co-ordinates becomes (0,4)

Finally you move from D to E, 2 blocks south such that point E becomes (0,2)

So, E is the friend's house and its coordinates are (0,2)

It can be diagramatically be represented by figure given below

Explanation:

Free Fall Motion

A free-falling object falls under the influence of gravity only. An object being acted upon only by the force of gravity is said to be in a state of free fall. Free-falling objects do not have air resistance.

If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is [tex]g = 9.8 m/s^2[/tex].

The distance traveled by a dropped object is:

[tex]\displaystyle y=\frac{gt^2}{2}[/tex]

Knowing the height h from which the object was dropped, we can find the time it takes fo hit the ground:

[tex]\displaystyle t=\sqrt{\frac{2h}{g}}[/tex]

Since y=24.3 m:

[tex]\displaystyle t=\sqrt{\frac{2\cdot 24.3}{9.8}}[/tex]

t=2.23 seconds

The ball takes 2.23 seconds to reach the ground
