Explanation:

Answer:

-->Phytoplankton are AUTOTROPHS

--> Both the Salmon and the grizzly bears are CONSUMERS.

--> Grizzly bears are SECONDARY CONSUMERS.

Explanation:

In an ecosystem, which is the basic functioning unit of nature, the biotic components is made up of all the living organisms in it. These organisms are divided into two main groups which includes:

--> The AUTOTROPHS: These are organisms that are able to use sunlight or chemical energy to manufacture their own food from simple inorganic substances. Since Autotrophs are the only organisms that can produce food in an ecosystem, they are also known as PRIMARY PRODUCERS. Example of autotrophs includes Phytoplankton( all green plants).

-->HETEROTROPHS: These organisms cannot manufacture their own food rather they feed on ready-made food which comes from the tissues of organisms in their environment. In an ecosystem, Heterotrophs are known as the CONSUMERS. Example of Heterotrophs includes all animals (salmon and the grizzly bears).

These biotic components of the ecosystem forms a feeding pathway through which energy and nutrients are transferred step by step among organisms. This is called a FOOD CHAIN. This feeding pathway follows a certain pattern:

--> it begins with a primary producer (Phytoplankton)

--> the primary producer is eaten by a primary consumer (salmon)

--> the primary consumer is eaten by a secondary consumer (grizzly bears)

That is the reason both the Salmon and the grizzly bears are CONSUMERS but while salmon is a primary consumer, grizzly bears are SECONDARY consumers.

correct answer below

Explanation:

Answer:

[tex]v = 22.54m/s[/tex] --- Velocity

[tex]h = 25.921m[/tex] --- Distance

Explanation:

Given

[tex]u = 0m/s[/tex] --- Initial velocity

Solving (a): Velocity after 2.3s

To do this, we use the first equation of motion

[tex]v = u + at[/tex]

Where

[tex]t = 2.3s[/tex]

[tex]a = g = 9.8m/s^2[/tex]

So, the equation becomes:

[tex]v = 0 + 9.8 * 2.3[/tex]

[tex]v = 0 + 22.54[/tex]

[tex]v = 22.54m/s[/tex]

Solving (b): Distance covered in 2.3s

We make use of:

[tex]h = ut + \frac{1}{2}gt^2[/tex]

This gives:

[tex]h = 0 * 2.3 + \frac{1}{2}*9.8 * 2.3^2[/tex]

[tex]h = \frac{1}{2}*9.8 * 5.29[/tex]

[tex]h = 25.921m[/tex]

This is true fact.

Answer: A

Explanation:

Just speed I think.

Speed is scalar, while velocity is a vector so you would need a direction. For acceleration you would need to know the specific speed at different points in time.

A cheetah can run 140 miles in 2 hours.

The information we can calculate about the cheetah given this information is the "speed" (A).

Answer:

Option ( B ) is correct .

Explanation:

To lift a heavy weight , inclined plane is used . Use of inclined plane , makes the task easier because instead of force mg , force mg sinθ is to be used which is less than mg . Here θ is inclination of inclined plane.

If h be the height by which weight is to be lifted

potential energy acquired by weight = mgh

work done by force mg sinθ = mgsinθ x d where d is displacement required .

mg sinθ x d = mgh  ( work done by force = potential energy stored in luggage )

d = h / sinθ

d will be more than h

Hence inclined plane increases the distance to be covered by force applied though it decreases the force itself.

Hence option ( B ) is correct .

Answer:

a=f/m

Explanation:

Strange as it may seem, the statement in the question appears to be TRUE.  

-- Before the shot, neither the cannon nor the ball is moving, so their combined momentum is zero.  

-- Since momentum is conserved, we know immediately that their combined momentum AFTER the shot also has to be zero.

-- (20g is rather puny for a "cannonball" ... about the same weight as four nickels. But we'll take your word for it and just do the Math and the Physics.)

-- Momentum = (mass) x (velocity)

After the shot, the momentum of the cannonball is

(0.02 kg) x (100 m/s ==> that way)

Momentum of the ball = 2 kg-m/s ==> that way.

-- In order for both of them to add up to zero, the momentum of the cannon must be (2 kg-m/s this way <==) .

Momentum of cannon = (5 kg) x (V m/s this way <==)

2 kg-m/s this way <== = (5 kg) x (V m/s this way <==)

Divide each side by (5 kg):

V m/s  =  (2/5) m/s this way <==

Speed of recoil of the cannon = -- 0.4 m/s

Explanation:

Answer:

18kgm/s

Explanation:

momentum of a body is given by:

M=mv, where m and v are the mass and speed respectively.

thus from the question ,simply ,

Momentum= 6•3=18kgm/s

Answer:

Difference = 1.83 hours

Explanation:

Let the two trips be A and B respectively.

Given the following data;

Distance A = 2000 miles

Speed A = 400 miles

Distance B = 2000 miles

Speed B = 480 miles per hour

To find the time spent;

a. For trip A.

Time A = distance A/speed A

Time A = 2000/400

Time A = 5 hours

b. For trip B.

Time B = distance B/speed B

Time B = 2000/480

Time B = 4.17 hours

Next, we would find the difference between the two trips.

Difference = Time A - Time B

Difference = 5 - 4.17

Difference = 1.83 hours

Therefore, the return trip was much quicker by 1.83 hours.

The return trip of the airplane will be quicker by 1.84 hours

It is given that

Distance covered by the plane D= 2000 miles

The average speed of the plane

 [tex]V_1=400\ \frac{Miles }{hour }[/tex]

The Return Average speed of the plane

[tex]V_2= 480\ \frac{Miles}{hour}[/tex]

Now we will first find the time taken by the airplane during the first visit.

[tex]V_1=\dfrac{Distance }{Time }[/tex]

[tex]Time = \dfrac{Distance }{V_1}[/tex]

Now by putting the values in the formula

[tex]T_1=\dfrac{2000}{400} =5\ hours[/tex]

Now for the return trip time taken by the plane

[tex]T_2=\dfrac{Distance }{V_2}[/tex]

[tex]T_2= \dfrac{2000}{480}[/tex]

[tex]T_2= 4.16\ hours[/tex]

Now the difference between the time will be

[tex]=T_1-T_2=5-4.16=0.86=1.84 \ Hours[/tex]

Thus the return trip of the airplane will be quicker by 1.84 hours
