Directions: Use the passage and the diagram below to answer the question. What is the average speed, in meters per second, of the trip across the field? (Write answer with all decimals but no units.)

Answer:

The answer is A) byee!!

Explanation:

Answer:by removing carbon dioxide from the body

Explanation:

I just got it right

Answer:

a.

Explanation:

Answer:

I am pretty sure it is C!

Explanation:

According to www.open.edu,

Elements are substances that are made from one type of atom.

Compounds are substances made from atoms of different elements joined by chemical bonds.

A mixture is made by simply mixing together elements and compounds.

Atoms are the basic building blocks.

i think A is incorrect because, while the statement may be correct, it is talking about Mixtures, not elements themselves!

B is incorrect because elements ARE able to combine to form compounds!

D is incorrect because ELEMENTS combine to create compounds, i am pretty sure compounds don't combine to create elements.

you are so wise how do you do it?

Answer:

Conduction is the transfer of heat between substances that are in direct contact with each other. ... Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them.

Answer:

The change in momentum (in kg*m/s) [tex]= 20[/tex]

Explanation:

The change in momentum is equal to

Final Momentum - Initial Momentum

As we know

Momentum is equal to the product of mass and velocity

M = m * v

Thus, change in momentum

[tex]m_2v_2 - m_1v_1[/tex]

here m1 = m2 = 2 Kg

Substituting the given values in above equation we get -

[tex]2 * 6 -( 2 *-4)\\12 + 8 = 20[/tex]kg m/s

Answer: B air masses

Answer:

2

Explanation:

Answer:

See answer below

Explanation:

In order to do this, we just need to apply the expression to determine the time of flight. This is given by:

t = 2 V₀ Sinθ / g   (1)

We have the initial speed which is 200 m/s, the angle of elevation to the horizontalis 60° and the gravity is 9.8 m/s². Replacing this data in the above expression we have:

t = 2 * 200 Sin60° / 9.8

Now that we have the time, we can determine the range or distance in the horizontal plane. This can be calculated using the following expression:

X = V * t   (2)

We already have the time, which is the time of flight, the initial speed using cos 60° (Cause it's horizontal plane), and replacing we have:

X = 200 cos60° * 35.348

X = 100 * 35.348

plz mark my answer as brainlist plzzzz vote me also hope this will be helpful to you

Answer:

See explanation

Explanation:

Range of a projectile is given by; U^2sin2θ/g

When θ = 45°

The maximum range is obtained as;

Rmax = U^2/g

Maximum range on earth = RME = U^2/g

Maximum range in the moon= RMM =U^2/g/6

Maximum range in Mars = RMMA = U^2/0.38g

a)

RME/RMM =  U^2/g/U^2/g/6

RME/RMM = 6

But RME = 3 m

RMM = 3 * 6 = 18 m

b)

RME/RMMA =U^2/g/U^2/0.38g

RME/RMMA = 1/0.38

But RME = 3 m

RMMA = 3/0.38

RMMA = 7.9 m

Answer:

F1 = 16 N and F2 = 24 N

Explanation:

Formula used => F = m×a and v-u= at

So, as we know force = mass × acc.

so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now

Here u= 0 as the objects are placed at rest initially..

thus, v= at

FOR 1ST BLOCK

16= <math> F1/5 </math> × 5 ==> F1 = 16 N

FOR 2ND BLOCK

15= <math> F2/ 8 </math> × 5 ==> F2= 24 N

Answer:

See Below.

Explanation:

I can't transpose the diagram onto Brainly. I'll do my best to describe what is going on.

Now you are ready to develop the equation

Clockwise

There is only 1 force where B is the Balance point that is going clockwise

10 * Force A

The AntiClockwise Moments

Platform: 4*10kg * 9.8 = 392 N m

Physics T: 2 * 75 * 9.8 = 1470 N m

So the Anti Clockwise moments = the clockwise moments.

10 * Force A = 392 NM  + 1470NM   Divide by 10. Remember that is in meters

Force A = 1862 N M / 10 10 M = 186 N

Does that make some sort of sense? It should Student A is the furthest distance from where all the action is at B. Therefore he is carrying the lightest weight.

Now what is the total force?

(75 + 10 ) * 9.8 = 85 * 9.8 = 833

This is one of those strange things that won't make sense until it does. Read the next sentence carefully. B is carrying most of the weight. Remember Newtons measure weight.

Support of A = 186 N

Support of B = x

Total of A+B = 933

186 + x = 833

x = 933 - 186

x = 647

So the forces are

A supports    186

B supports    647

Hope it helps;)

Answer:

The radius of the curve is 9,183.67 m.

Explanation:

Given;

velocity of the jet plane, v = 600 m/s

acceleration of the jet plane, a = 4g = 4 x 9.8 m/s² = 39.2 m/s²

The radius of the curve is calculated from centripetal acceleration formula as given below;

[tex]a = \frac{v^2}{r} \\\\r = \frac{v^2}{a} \\\\r = \frac{600^2}{39.2} \\\\r = 9,183.67 \ m[/tex]

Therefore, the radius of the curve is 9,183.67 m.
