The TERTIARY CONSUMER has the least energy available to it.
Answer:
Explanation:
Given data
Length L=2.9 cm=0.029m
Speed of sound v=335 m/s
to find
Fundamental frequency f
Solution
As we know that frequency is given as:
f=v/λ
Answer:
4.57 degree
Explanation:
As the dolphin is under water, so the angle is angle of refraction which is equal to 48.4 degree.
refractive index of water, n = 1.333
Let the angle of incidence which is the angle between the incident ray and the normal is i.
By use of Snell's law
i = 85.43 degree
Angle made with the horizon = 90 - 85.43 = 4.57 degree
Answer:
It's C. Length
Explanation:
Just think of a ruler. Hope I helped! :)
Weight of an object is given by the formula W = m x g , where
m : mass of the object
g : gravitational acceleration
It is <u>independent of the horizontal </u><u>acceleration</u>.
<h3>What do we mean by weight of an object?</h3>
Weight is a gauge of how strongly gravity is<u> pulling something down.</u> It is dependent on the object's mass, or how much matter it consists of. It also depends on the <u>object's uniformly distributed</u> downward acceleration caused by gravity.
This equation can be used to express weight:
W = m x g
<h3>What is the difference between weight and mass of an object?</h3>
In everyday speech, the phrases "mass" and "weight" are frequently used interchangeably; nevertheless, the two concepts don't have the same meaning. In contrast to weight, which is a <u>measurement of</u> how the <u>force</u> of gravity works upon a mass, mass is the <u>amount of substance</u> in a material.
