Answer:
The state of a certain type of land or a biome.
Answer:
In physics, work is defined as the use of force to move an object. For work to be done, the force must be applied in the same direction that the object moves. Work is directly related to both the force applied to an object and the distance the object moves. <em>[I HOPE THIS HELPS* PLS MARK ME BRAINLIEST]</em>
Answer:
20 ms⁻¹
360 J
Explanation:
Kinetic energy is the energy possessed by a moving object solely due to its motion.
You can get the K.E. of an object using the equation,
K.E. = (1/2)mv² where all terms in usual meaning
So you get,
K.E. = 36000 = (1/2)×180×v²
v = 20 ms⁻¹
Also,
K.E. = (1/2)×80×3² = 360 J
Answer:
129.74 Hz
Explanation:
Given:
Wave velocity ( v ) = 346 m / sec
wavelength ( λ ) = 2.69 m
We have to calculate Frequency ( f ) :
We know:
v = λ / t [ f = 1 / t ]
v = λ f
= > f = v / λ
Putting values here we get:
= > f = 346 / 2.69 Hz
= > f = 34600 / 269 Hz
= > f = 129.74 Hz
Hence, frequency of sound is 129.74 Hz.
The Pacific plate collides with and is subducted under four other crustal plates. The area where this happens has lots of volcanic activity. This area is called the Ring of Fire.
This is a place under the Pacific Ocean and it has numerous
volcanic eruptions and earthquakes and so this region is called the Ring of
Fire. In this place there are about 450 active and dormant volcanoes and it is
almost 75 percent of the volcanoes present in our earth.
