Yes

Explanation:

The flow of nutrients through ecosystem is cyclic as the nutrients move from one trophic level to another trophic level all the way up and then back down.

Answer:

Heavy objects fall at the same rate (or speed) as light ones. The acceleration due to gravity is about 10 m/s2 everywhere around earth, so all objects experience the same acceleration when they fall.

Explanation:

Answer:

D) 3 ohms

Explanation:

According to one law

V = IR

Where V = voltage or potential difference

I =current

R =resistance

Making R the subject

R= V/I

R= 12/1.5

R=8 ohms

Sum of resistance of resistors in series equals the total resistance

R(total) = R1+ R2

8 =5+ R2

8-5=R2

3=R2

Answer:

A.) 3.19s

B.) 0

C.) 55.1

Explanation:

Given that a rock fell of the edge of a cliff and encountered a displacement of 50m. The final vertical velocity of the rock was 10m/s.

To Find the

A.) time the rock was in the air,

Given that

h = 50m,

initial velocity U = 0,

acceleration due to gravity g =9.8m/s^2

Using second equation of motion:

h = Ut + 1/2gt^2

Substitute all the parameters into the equation

50 = 1/2 × 9.8 × t^2

100 = 9.8t^2

t^2 = 100/9.8

t^2 = 10.2

t = 3.19s

B.) the horizontal velocity when the rock left the cliff

The horizontal velocity is equal to zero since horizontal acceleration is zero.

C.) and the vertical displacement the rock had.

Using the third equation of motion.

V^2 = U^2 + 2gH

Where U = 0

V = 10m/s

Substitute all the parameters into the formula

10^2 = 0 + 2 × 9.8 × H

100 = 19.6H

H = 100/19.6

H = 5.1

The vertical displacement = 50 + 5.1

The vertical displacement = 55.1 m

Explanation: Dont quote me on that

Answer:

The car will take 5 seconds

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes uniformly in time.

If the object starts from a speed vo during a time t with an acceleration a, then its final speed is:

[tex]v_f=v_o+at[/tex]

The car is accelerating at a rate of a= 4~m/s^2 and reaches a speed of vf=20 m/s starting from rest (vo=0).

From the equation shown above, we solve for t:

[tex]\displaystyle t=\frac{v_f-v_o}{a}[/tex]

[tex]\displaystyle t=\frac{20-0}{4}[/tex]

[tex]\displaystyle t=\frac{20}{4}[/tex]

t = 5 seconds

The car will take 5 seconds

[tex]\huge\boxed{\sf T = 2.04\ secs}[/tex]

Explanation:

Given Data:

Initial Velocity = [tex]\sf V_{i}[/tex] = 20 m/s

Angle = [tex]\sf \theta[/tex] = 30°

Acceleration due to gravity = g = 9.8 m/s²

Required:

Time of flight = T = ?

Formula:

[tex]\sf T = \frac{2\ V_{i}\ sin\theta}{g}[/tex]

Solution:

Putting values in the above formula

T = 2(20)sin 30 / 9.8

T = 40 (0.5) / 9.8

T = 20 / 9.8

T = 2.04 secs

Answer:

to know what that specif animal or thing does in the food chain

Explanation:

Answer:

(a) h = 5.1 m

(b) v = 14.13 m/s

Explanation:

(a)

We will use the law of conservation of energy. For this situation it states that:

Loss in Potential Energy of Sphere = Gain in Kinetic Energy of the Sphere

mgh = (1/2)mv²

h = v²/2g   --------------- equation (1)

where,

h = height = ?

v = speed at lowest point = 10 m/s

g = 9.8 m/s²

Therefore,

h = (10 m/s)²/(2)(9.8 m/s²)

h = 5.1 m

(b)

using the equation (1)

h = v²/2g

v = √2gh

where,

v = velocity = ?

g = 9.8 m/s²

h = height = 2(5.1 m) = 10.2 m

Therefore,

v = √[2(9.8 m/s²)(10.2 m)]

v = 14.13 m/s

The height from which the sphere was released is 5.1 m

When the height is doubled, the speed of the sphere becomes 14.14 m/s.

The given parameters:

The height from which the sphere was released is calculated as follows;

[tex]P.E = K.E\\\\mgh = \frac{1}{2}mv^2\\\\gh = \frac{1}{2}v^2\\\\h = \frac{v^2}{2g}\\\\h = \frac{(10)^2}{2(9.8)} \\\\h = 5.1 \ m[/tex]

When the height is doubled, the speed of the sphere becomes;

[tex]h = \frac{v^2}{2g} \\\\v^2 = 2gh\\\\v = \sqrt{2gh} \\\\v = \sqrt{2 \times 9.8 \times (2 \times 5.1)} \\\\v = 14.14 \ m/s[/tex]

The statement about the layers of the Earth that both Sophia and Malik would identify as correct is: C. The mantle is denser than the crust.

Earth is one of the planets that rotates on its axis and revolves around the Sun. Also, planet Earth is the only planet known to harbor and support life.

Based on astronomical records, planet Earth comprises four (4) distinct layers starting at the center and these include:

The mantle has a density of 4.5 [tex]g/cm^3[/tex] while the crust has a density of 2.6 [tex]g/cm^3[/tex] because temperature and pressure within planet Earth increases with depth.

In conclusion, the mantle is denser than the crust since it is made up of metals rather than solid rocks and minerals which are found within the crust.

Longitudinal waves are those waves which move in the same direction as of the particle of the medium. That means, The Particles of the medium move forward and backward just like the Wave move forward so they propagate in the same direction.

The Sound wave is the example of the longitudinal wave as it propagates in  the same direction as the particle do.

Transverse wave are those waves which propagate in the perpendicular direction as of the particle of the medium. That means, The particle moves up and down but the wave propagate in forward direction. So they dont move in similar direction but perpendicular.

Water wave is the perfect example of the transverse wave as you can see that water particles form crest(Up the midline) and trough(down the midline) i.e. upward and downward movement but the water actually moves forward in direction.

Answer: The correct statement order from the earliest to the most recent is (US satellite Explorer launched, NASA was established, first man orbited the Earth, first man walked on the moon.)

Explanation:

The United States first Satellite was launched in the date of February 1, 1958. It was given the name 'Explorer 1'. It was a cosmic ray detector which was constructed to measure the radiation environment in earth orbit.

NASA (National Aeronautics and Space Administration) was established in the year 1958 on the first day of October by United States of America. This was created as a response to the Soviet Union over thier first Satellite launch.

First man orbited the earth in the year 1961 on April 12. This was achieved by a Soviet Cosmonaut Yuri Alekseyevich Gagarin.

The first human on the moon is Neil Armstrong through the spacecrafts called Apollo's 11. This event occurred on 20 July 1969

The correct order from the earliest to the most recent is US satellite Explorer launched, NASA was established, first man orbited the Earth, first man walked on the moon.

Answer:

what?

Explanation:

Answer:  71.43 kilograms

This value is approximate rounded to two decimal places.

=====================================================

Explanation:

The ground is pushing up with a normal force of 700 N. Because the box is sitting still, this means the force of gravity is pulling the box down with a force of 700N to keep things balanced.

If the force of gravity was greater than 700N, then the box would fall through the ground. If the force of gravity was smaller than 700N, then the box would be accelerated upward. Since neither event is happening, the force of gravity must be equal to the normal force.

Now turn to Newton's second law which says

F = ma

where F is the force, m is the mass and 'a' is the acceleration. We're given the acceleration of gravity is roughly 9.80 m/s^2. So a = 9.80

The force we'll plug in is F = 700. The value of m is unknown, but we can solve for it as such

F = ma

700 = m*9.80

700 = 9.08m

9.80m = 700

m = 700/9.80

m = 71.4285714285714

m = 71.43

The mass is roughly 71.43 kilograms.
