Answer:

They are not the same

Explanation:

Several animal species are able to hearfrequencies well beyond the human hearing range, and like anylimalas are not all alike some will have similar hearing ranges but not all of them will have the same.

Answer:

Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine investigation for hearing loss usually involves an audiogram which shows threshold levels relative to a normal.

Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100,000 Hz. Elephants can hear sounds at 14–16 Hz, while some whales can hear infrasonic sounds as low as 7 Hz (in water).

A small airplane is sitting at rest on the ground. Its center of gravity is 2.58 m behind the nose of the airplane, the front wh

otez555 [7]

Answer:

The percentage of the weight supported by the front wheel is A= 19.82 %

Explanation:

From the question we are told that

The center of gravity of the plane to its nose is $z = 2.58 m$

The distance of the front wheel of the plane to its nose is $l = 0.800\ m$

The distance of the main wheel of the plane to its nose is $e = 3.02 \ m$

At equilibrium the Torque about the nose of the airplane is mathematically represented as

$mg (z- l) - G_B *(e - l) = 0$

Where m is the mass of the airplane

$G_B$ is the weight of the airplane supported by the main wheel

So

$G_B =\frac{mg (z-l)}{(e - l)}$

Substituting values

$G_B =\frac{mg (2.58 -0.8 )}{(3.02 - 0.80)}$

$G_B = 0.8018 mg$

Now the weight supported at the frontal wheel is mathematically evaluated as

$G_F = mg - G_B$

Substituting values

$G_F = mg - 0.8018mg$

$G_F = (1 - 0.8018) mg$

$G_F = 0.1982 mg$

Now the weight of the airplane is = mg

Thus percentage of this weight supported by the front wheel is $A = 0. 1982 *100 =$ 19.82 %

drek231 [11]

Answer:

3120J

Explanation:

Given parameters:

C = Specific heat capacity = 0.8J/g°C

Initial temperature = 20°C

Mass given = 5g

Final temperature = 800°C

Unknown:

Energy given to the mass = ?

Solution:

To find the energy given to the mass, let us simply use the expression below:

H = m c ΔT

H is the unknown, the energy supplied

m is the mass of the substance

c is the specific heat capacity

ΔT is the change in temperature

Input the variables;

H = 5 x 0.8 x (800 - 20) = 3120J
