A fundamental niche can be defined as the range of environmental conditions in which each of the species survives. The realized niche can be termed as the range of environmental conditions in which a species is really found.

Answer:

0 m/s^2

Explanation:

Acceleration is the change in velocity / time

=> In this case there isn't any change in velocity

=> It is = to 0.

Two round concentric metal wires lie on a tabletop, one inside the other. The inner wire has a diameter of 21.0 cm and carries a

Burka [1]

Solution :

a). B at the center :

$=\frac{u\times I}{2R}$

Here, one of the current is in the clockwise direction and therefore, the other current must be in the clockwise direction in order to cancel out the effect of the magnetic field that is produced by the other.

Therefore, the answer is ANTICLOCKWISE or COUNTERCLOCKWISE

b). Also, the sum of the fields must be zero.

Therefore,

$\left(\frac{u\times I_1}{2R_1}\right) + \left(\frac{u\times I_2}{2R_2}\right) = 0$

So,

$\frac{I_1}{d_1}= \frac{I_2}{d_2}$

$=\frac{16}{21}=\frac{I_2}{32}$

$I_2=24.38$ A

Therefore, the current in the outer wire is 24.38 ampere.

A motorcycle is moving at a constant speed of 45km/h how long does it take the motorcycle to travel a distance of 20km?

harina [27]

Answer:

It takes 1600 seconds or $\frac{4}{9}$ hours to travel a distance of 20 km.

Explanation:

Given:

Speed of the motorcycle, $v=45\textrm{ km/h}$

Distance traveled by the motorcycle, $D=20\textrm{ km}$

We know that,

$Distance = \frac{Speed}{Time}$

∴ $Time =\frac{Distance}{Speed}=\frac{D}{v}$

Plug in 20 km for $D$ and 45 km/h for $v$ . Solve for time.

⇒ Time = $\frac{20}{45}=\frac{4}{9}\textrm{ h}=\frac{4}{9}\times 3600=1600\textrm{ s}$

Therefore, the time taken to travel a distance of 20 km is 1600 seconds or $\frac{4}{9}$ hours.

21. A toy car starts from rest and begins to accelerate at 11.0 m/s2. What is the toy

svlad2 [7]

Answer:

Explanation:

Given parameters:

Initial velocity = 0

Acceleration = 11m/s²

Time = 6s

Unknown:

Final velocity = ?

Solution:

From the given parameters, we use one of the appropriate equations of motion to solve this problem.

V = U + at

V is the final velocity

U is the initial velocity

a is the acceleration due to gravity

t is the time taken

Input the parameters and solve;

V = 0 + 11 x6

V = 66m/s

The final velocity is 66m/s
