Answer:
Predator is an organism or group of organisms which kills and consumes other organisms in an ecosystem.Prey is an organism or group of organism which is killed by other organism in order to obtain them as food. Predation and prey interaction is necessary to make balance in surplus increase in population of prey.
An example including two different species might can compete over the same prey is a tiger and lion species competing for a same prey zebra. This shows a predator and prey relationship.
In simple words, flux can be stated as the rate of flow of a fluid, radiant energy, or particles across a given area.
Explanation:
Mutual Flux:
Leakage Flux:
Magnetizing flux
Answer:
The object is sitting
Explanation:
Therefore the object cannot be in current motion as no force has been acted upon it (exept gravitational force)
The frequency is 1/5 second, and the period is 5 Hz.
The period is 1/5 second, and the frequency is 5 Hz.
The period is 5 s, and the frequency is 5 Hz.
The period is 1/5 second, and the frequency is 5 Hz.
Explanation:
Let's start by reviewing some definitions about waves:
- The period of a wave is the time taken for the wave to make one complete cycle. It is indicated with T and it is measured in seconds (s)
- The frequency of a wave is the number of complete cycles made by the wave in one second. It is indicated with f and it is measured in Hertz (Hz). It is equal to the reciprocal of the period:
where f is the frequency and T is the period.
In this problem, we have a wave that passes a given point five time per second. This means that the number of oscillations per second is five, and so its frequency is:
It follows than the period of the wave is:
Therefore, the correct statement is
The period is 1/5 second, and the frequency is 5 Hz.

Explanation:
b. a different side of the moon faces Earth each day.
c. you never see the far side of the moon from Earth.
d. the far side of the moon is visible only during the full moon phase.
Answer:
C. The moon orbits and rotates the same, so we NEVER see the far side of the moon from earth
Explanation:
As per the question, the object is thrown in vertically upward direction.
The initial velocity of the ball [u] = 9 m/s.
We are asked to calculate the velocity of the ball after 2 second.
When the ball goes up, the only force that acts on the ball is the force of gravity.
Hence the acceleration of the ball is nothing else than acceleration due to gravity i.e g and it is downward in direction.
Here, it will be considered negative as it is downward in direction .
From equation of kinematics we know that-
v = u +at [Here v is the final velocity and a is the acceleration.
= 9 +[-9.8]×2 m/s
= 9-19.6
= -10.6 m/s
Here the negative sign indicates that the ball is falling downward. It is coming back after reaching its maximum height.
Here the total time of flight of the ball is-
If the ball is thrown from certain height from the ground, then the velocity of the ball will be the calculated value.
If the ball is thrown from the ground, obviously the ball will heat the ground after 1.8367 seconds later.So the velocity of the ball will be zero after 2 seconds.
