A construction worker uses a hammer to drive a sharp nail into a concrete wall. What two simple machines is the construction worker using when he does this task-(D) a wedge and a lever
Explanation:
Simple machines are the tools an individual uses in his day to day life in order to make its work simpler.
For Example: Axles and wheel make it simple to carry a heavy object in a shopping cart.
<u>A hammer is a type of lever,</u>and is also a type of simple machines.A hammer can be defined as a heavy rigid bar moves around a fixed point ,that point is called fulcrum .
Wedges is also a form of simple machine and the inclined plane forms its foundation. A wedge can be referred to as the sharp edge of an inclined plane.They are used to level out a structure of an object
Thus we can say that A construction worker uses a hammer to drive a sharp nail into a concrete wall. What two simple machines is the construction worker using when he does this task-(D) a wedge and a lever
Answer:
Option (D)
Explanation:
The westerlies are the wind generated from the western side and eventually blows towards the sub-polar low areas in both the hemisphere.
The polar easterlies are defined as the cold and dry wind that blows from the high pressure polar areas towards the low pressure areas in both the hemisphere. These polar easterlies and westerlies meets at the low pressure zone forming the sub-polar low areas.
Thus, the correct answer is option (D).
returns freshwater to the earth
occurs after condensation
is roughly equal to the amount of evaporation
Explanation:
Precipitation returns fresh water to the earth, occurs after condensation and is roughly equal to the amount of evaporation.
The process of precipitation is a key component of the hydrologic cycle.
- In the hydrologic cycle, precipitation follows condensation of water vapor in the atmosphere.
- Precipitation often takes the form of rainfall and snow.
- It is any product of condensation of water in the atmosphere that falls back under the influence of gravity.
- In the hydrologic cycle, water leaves the surface of the earth in form of vapor as result of evaporation.
- Most times , the amount of evaporation is roughly equal to that of precipitation.

Explanation:
Hypogeal germination is when the plant is germinated under the ground. An example of this would be the pea plant.
epigeal germination is the opposite of that. Germination takes place above the ground. normal bean plants have epigeal germination
When the two waves meet, there are two possibilities:
1.If the waves were both in phase and moving in the same direction, then, the amplitude will double, this is called constructive interference.
2. If the two waves were exactly out of phase, then they will try to move the water surface in all directions, thus, no movement and the waves cancel out. This is called destructive interference.
