Answer:
, where m is the mass of the pendulum
Explanation:
As we know that mechanical energy is the sum of kinetic energy and potential energy.
Since the Pendulum at its highest point has zero velocity, its kinetic energy at this point is equal to zero.
Thus, here in this mechanical energy will be equal to the potential energy only.
Potential energy is equal to the product of gravity constant, mass of the body and the height of the pendulum
Thus,
Hence,
Answer:
The two factors are:
• The kind/type of surface involved.
• The force that the surface are being pushed together.
Explanation:
Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.
When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.
The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.
Gametophytes are photosynthetic & have root-like rhizoids.
The correct answer is D. Accessory fruit
Explanation.
Fruits are structures that develop from the fertilized ovary of plants and that contain the seed of it, this includes simple, aggregate and multiple fruits. However, there is one type of fruits that do not develop from ovary but from other tissues that are usually near the ovary, these fruits are called accessory or pseudo fruits as they do not fit completely the definition of regular fruits, this includes fruits such as strawberries or pineapples that develop from tissues different to the ovary.
It gets transferred through out animals
hope this helps
