When geologists refer to the "big five," what are they referring to?
the five most important organisms that have become extinct.
the five largest mass extinctions in earth's history.
the five most influential events that have changed the surface of the earth.
the five most important inventions that have allowed scientists to study mass extinctions.
ill provide the answer choices here, assuming its from edge.
a) sasha’s monthly expenses would be less for buying than for renting.
b) the extra expenses in the mortgage payment cover all maintenance and repairs.
c) sasha’s down payment will likely be less if she decided to buy.
d) sasha will own the house and earn equity as its value increases.
the correct answer is d) sasha will own the house and earn equity as its value increases.
the engine generates a force of 11000 newtons.
to determine the force, first you will need to calculate the acceleration. acceleration is change in velocity over change in time, so in this case:
force is then determined as
this is the forward force, i.a. one acting in the direction of the car's acceleration. we are told that there is no inefficiency in the engine and transmission, therefore this same force is generated by the engine.
in this question we have given that
velocity of bus= towards east
velocity of man= towards east
it means both are moving in the same direction
therefore velocity of man in the frame of reference of a stationary observer is given as=velocity of bus+velocity of man
= towards east
therefore, therefore velocity of man in the frame of reference of a stationary observer is towards east
the characteristics of sound waves are as follows :
(1) intensity : the power per unit area carried by a sound wave is called as the intensity of wave. so, . its unit is .
(2) loudness : loudness means how the listener perceives the sound intensity. it is determined by the intensity of sound waves.
(3) frequency : the number of to and fro oscillations of sound wave per unit time is called as its frequency. its unit is hz or hertz.
(4) pitch : pitch means the quality of sound. it is closely related to frequency. for high pitch, the number of waves are more.
