The acceleration of the object as it begins to move is equal to 250 m/s². Therefore, option (B) is correct.
What is acceleration?Acceleration produced by an object can be defined as the rate of change of velocity of an object w.r.t. time. The acceleration is a vector quantity because it possesses both magnitude and direction. Acceleration is also expressed as the second derivative of position w.r.t. time and the first differentiation of velocity of an object w.r.t. time.
According to Newton's 2nd law, the force on an object is equal to the mass times acceleration of an object.
F = ma
and, a = F/m
Given, the force acting on an object to move it, F = 7N
The mass of the object, m = 0.028 Kg
The acceleration of the object = 7/0.028 = 250 m/s²
Therefore, the acceleration of the object when it begins to move is 250 m/s².

Weather is caused by the rising and falling of warm and cool air called ( ). These currents affect the different air pressures in the atmosphere( ) . Response area occurs when the air cools and begins to sink, while ( ) occurs when the air warms and begins to rise. The differences between these pressures are what causes
( ). Convection can also create ( ) in a small local area.
Answer:Movement of air caused by temperature or pressure differences is wind. Where there are differences of pressure between two places, a pressure gradient exists, across which air moves: from the high pressure region to the low pressure region. This movement of air, however, does not follow the quickest straight line path. In fact, the air moving from high to low pressure follows a spiralling route, outwards from high pressure and inwards towards low pressure. This is due to the rotation of the Earth beneath the moving air, which causes an apparent deflection of the wind to the right in the northern hemisphere, and left in the southern hemisphere. Consequently, air blows anticlockwise around a low pressure centre (depression) and clockwise around a high pressure centre (anticyclone) in the northern hemisphere (see Figure 3.1). This situation is reversed in the southern hemisphere.

What type of circuit does this figure represent?
open parallel circuit
closed series circuit
open series circuit
closed parallel circuit
Answer:
the best answer would be b. :)
Explanation:
Answer:
Closed series circuit
A closed series circuit is characterized with having a smooth and running path in which electric current flows .In this type of circuit there is no breakage found and is the same as the example provided above.
The open circuit usually has one or more forms of breakage which hinders the smooth flow of electric current and makes it less functional.
The pattern of electric current flow is also in series as there is no parallel connection which makes closed series circuit correct and the closed parallel false

Describe how plates create mountain ranges like the Himalayas.
2. Diagram how pulling apart continental crust could create mountains and basins. What are the mountains and
basins called?
3. Why don’t strike slip faults create mountains?
Answer: Describe how plates create mountain ranges like the Himalayas.
Answer- Most of the world's largest mountains form as plates collide at convergent plate boundaries. This creates mountains. Folding and faulting in these collision zones makes the crust thicker. The world's highest mountain range, the Himalayas, is growing as India collides with Eurasia
2. Diagram how pulling apart continental crust could create mountains and basins. What are the mountains and
basins called? Answer- When tensional stresses pull crust apart, it breaks into blocks that slide up and drop down along normal faults. The result is alternating mountains and valleys, known as a basin-and-range

Answer:
1. The Speed is 390
2. The Frequency is 425 Hz
3. The Wavelength is 1.3
Explanation:
1. To find the speed of a wave you have to do the formula of speed.
Speed = Wavelength x Wave Frequency.
Speed = 1.5 * 260
= 390
2.
Formula
F= [tex]\frac{1}{T}\\[/tex]
F = 340 / 0.8
= 425
3.
Formula
Wavelength = speed / frequency
Wavelength = 440 / 344 (rounded to nearest tenth if necessary)
= 1.3
Answer:1. The Speed is 390

density of water [d]=1000kg/m³
acceleration due to gravity [g]=9.8m/s²
Now
pressure=dgh=1000×6×9.8=58800 pascal
Explanation:
solution
Given,
height (h)= 6m
density of the water (d)= 1000 kg\m^3
acceleration due to gravity (g)= 9.8 m\s^2
pressure=?
Now, We know that,
Pressure= hdg
= 6 * 1000* 9.8
