Answer:

F = 12 N

Explanation:

Given that,

Force of 5 N and 7 N respectively act on an object.

We need to find the resultant of the two vectors be at a maximum.

Force will be maximum when two forces acts in same direction. It means we can simply add them i.e.

F = 5 N + 7 N

F = 12 N

Hence, the resultant force is 12N.

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:

*Atomos of a certain element contain a fixed amount of energy.

Explanation:

The atoms are said to be closed systems because the number of protons, neutrons and electrons is fixed, so these elements each have an energy given by the electrical interaction with the other elements.

Consequently, the correct answer is: Atomos of a certain element contain a fixed amount of energy.

Answer:

Atoms of a certain element contain a fixed amount of energy.

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

this question is centered around newtons second law f=ma

First you need to find the acceleration

[tex] acceleration = \frac{8 - 0}{22} [/tex]

that gives you 0.36 recurring(on both numbers) m/s²

mass= force ÷ acceleration

[tex] mass = \frac{31}{0.36recurring} [/tex]

mass= 85.25 kg

if you want to check

f=ma

85.25 × 0.36 recurring (remember its on both numbers not just 6) = 31 N

Answer:

Explanation:

Givens

F = 31 N

vi = 0

vf = 8 m/s

t = 22 seconds

m = ?

Formula

F = m ( vf - vi)/t

Solution

31 = m (8 - 0) / 22             Multiply both sides by 22

31 * 22 = 8 * m

8m = 682                          Divide by 8

m = 682 / 8

m = 85.25

thermal,true the explanation is because the other guy said so

Answer:

R = m⁴/kg . s

Explanation:

In this case, the best way to solve this is working with the units in the expression.

The units of velocity (V) are m/s

The units of density (d) are kg/m³

And R is a constant

If the expression is:

V = R * d

Replacing the units and solving for R we have

m/s = kg/m³ * R

m * m³ / s = kg * R

R = m * m³ / kg . s

This should be the units of R

Answer:

The angle of incidence is the angle between this normal and the incident ray; the angle of reflection is the angle between this normal and the reflected ray. According to the law of reflection, the angle of incidence equals the angle of reflection.

Explanation:

:)

Answer:

hope my answer helps

Explanation:

second law of reflection states that the angle of incidence equals to the angle of reflection,

this is the basic relationship,

so the angle of incidence is also equals to angle of reflection

Answer:

B.dunes

Explanation:

sand dunes are created by wind

The landform which is formed from the destructive and constructive processes of wind forces is dunes. Hence, option B is correct.

An anthropogenic or natural land feature on the solid surface of the Earth or another planetary body is referred to as a landform. A given terrain is made up of several landforms, and topography refers to how these landforms are arranged in the surrounding area. In addition to shoreline characteristics like bays, peninsulas, and seas, landforms also include hills, mountains, canyons, and valleys. Submerged structures like volcanoes, mid-ocean ridges, and major ocean basins are also considered to be landforms.

Physical characteristics of landforms, such as height, slope, orientation, stratification, rock exposure, and soil type, are used to classify them. Intuitive elements like berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and many more structural and size-scale elements, including different types of inland and marine waterbodies and sub-surface features, are all examples of gross physical features or landforms.

The landform made of wind are :

The erosional landform madeup of wind is Mushroom rock, zeugen, demoselles, yardang etc.

Answer:

2450 J

Explanation:

Given that,

A 50Kg girl jumps off a 5-meter-high diving board.

We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,

[tex]K=mgh\\\\K=50\times 9.8\times 5\\\\K=2450\ J[/tex]

So, her kinetic energy right before she hits the water is equal to 2450 J.

Answer:

The force, exerted by Big Ben on the Empire State Building is 2.66972 × 10⁻⁷ N

Explanation:

The question relates to the force of gravity experienced between two bodies

The given parameters are;

The mass of Big Ben, M₁ = 1 × 10⁸ kg

The mass of the Empire State Building, M₂ = 1 × 10⁹ kg

The distance between the two Big Ben and the Empire State Building, r = 5,000,000 meters

By Newton's Law of gravitation, we have;

[tex]F=G \times \dfrac{M_{1} \times M_{2}}{r^{2}}[/tex]

Where;

F = The force exerted by Big Ben on the Empire State Building and vice versa

G = The universal gravitational constant = 6.67430 × 10⁻¹¹ N·m²/kg²

M₁, M₂, and r are the given parameters

By plugging in the values of the parameters and the constant into the equation for Newton's Law of gravitation, we have;

[tex]F=6.67430 \times 10^{-11} \times \dfrac{1 \times 10^8 \times 1 \times 10^9}{(5,000,000)^{2}} = 2.66972 \times 10^{-7}[/tex]

The force, 'F', exerted by Big Ben on the Empire State Building is F = 2.66972 × 10⁻⁷ N.

Answer:

29 m/s.

Explanation:

Hope this helps.

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

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.

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.
