The appropriate answer is c. silty clay loam. This is the most likely soil that was present in the garden before sand was added to balance it. This type of soil contains an even mix of silt and clay. This type of soil does not drain well and tends to hold water. This would not be suitable for most garden variety plants. Adding sand to the soil ensures better drainage and removes moisture that would rot roots or create conditions for fungi to develop.
<h2>Right answer: Sea breeze </h2>
The sea breeze is formed because during the day the surface of the land on the coast tends to warm up before and more than the surface of the sea. This difference in temperature between these two air masses means that on a sunny day the land warms up much more than the ocean causing a small area of low pressure.
Then, the air rises as the land warms it and the colder air located on the surface of the sea forms a high pressure zone that makes this air mass tend to occupy the space left by the warmer air that has ascended on the coast. Therefore, the mass of air of a high pressure on the ocean always tends to move towards the zone of low pressure located on the coast.
It is important to note that the <u>sea breeze blows perpendicularly to the coast</u> and that the best breezes are formed in the spring and summer seasons because during the spring the water temperature is still cold and during the summer the sun produces high temperatures over the land in the coast.
<h2>So, <u>
the greater the temperature contrast </u>
between the land and the sea, <u>
the greater the force of the wind generated</u>

Answer: force of gravity on the body due to height difference above the earth's surface
Explanation: as you increase the height of a body above ground, you do work against gravity in moving it from a point on the earth's surface to that point. So a body falling has a stored up gravito-potential energy which acts on it downward due to its mass, accelerating it downwards
Answer b): kinetic energy of the body
Explanation: the downward force produces an acceleration of magnitude 9.81m/s2 downwards which means an increasing velocity. This increasing velocity means the kinetic energy of the body is increasing (kinetic energy is proportional to velocity of the body squared)
True if you actually did it. false if you didn't
Answer:
45.31 J
Explanation:
We are given that
Mass of baseball , m=0.145 kg
Initial velocity, u=0
Final velocity, v=25 m/s
We have to find the work done on the baseball to bring it from rest to 25 m/s
We know that
Work done = Change in kinetic energy
Work done, W=
Using the formula
Work done, W
Work done=
Work done, W=45.31 J
Hence, the work done on the baseball to bring it from rest to 25 m/s
=45.31 J
