Answer:

The weight of an object at the poles is more than the weight of the object at the equator

Explanation:

The shape of the Earth is an ellipsoid such that the distance from the North and South poles to the Earth's center, R₁, is less than the distance from the Equator to the center of the Earth, R₂

The weight of an object is given by the universal gravitational law as follows;

[tex]Weight = F_{gravity} =G\times \dfrac{M \cdot m}{R^{2}}[/tex]

Where;

[tex]F_{gravity}[/tex] = The force of gravity = The weight of an object

G = The universal gravitational constant

M = The mass of the Earth

m = The mass of the object

R = The radius of the Earth

Where R₁ < R₂, we have;

The weight at the Poles, W₁ = [tex]G\times \dfrac{M \cdot m}{R_1^{2}}[/tex]

The weight at the Equator, W₂ = [tex]G\times \dfrac{M \cdot m}{R_2^{2}}[/tex]

We have;

[tex]\left(G\times \dfrac{M \cdot m}{R_1^{2}} \right) > \left(G\times \dfrac{M \cdot m}{R_2^{2}} \right) \because R_1 < R_2[/tex]

Therefore, the weight of an object at the poles, W₁, is more than the weight of the object at the equator, W₂

Answer:

D

Explanation:

The relationship between bond strength and the melting and boiling points can be explained as the force between the particles increases, and the melting and boiling points also increase.​Therefore the correct option is D.

It is a temperature at which the pressure exerted by the external atmosphere is equal to the vapor pressure of the substance.

The boiling point depends on atmospheric pressure, temperature, bond strength, and vapor pressure of the liquid.

The bond strength between different atoms of the substance greatly influences the boiling point and melting point.

Explanation:

Según el modelo cinético, las moléculas de gas están en constante movimiento.

La energía cinética promedio de las moléculas del gas depende de la temperatura del gas y de la masa molar del gas.

Si los dos gases ocupan el mismo volumen a la misma temperatura, la energía cinética promedio ahora depende de la masa molar de los gases individuales. Cuanto menor sea la masa molar del gas, mayor será la velocidad media de las moléculas del gas.

El oxígeno gaseoso tiene una masa molar menor que el dióxido de carbono. Por lo tanto, el oxígeno tiene una velocidad molecular promedio mayor que el dióxido de carbono.

Answer:

cause by imbalances between stroms cloud and grounds , or within the cloud themselves.

Explanation:

Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

The positive and negative charges grow large enough, a giant spark lightning, occurs between the two charges within the cloud.

The naturally occurring electrostatic discharge with high voltage for short duration from the cloud to the ground or within the cloud. The lightning can be seen by a flash of light that could be followed by the strong sound. Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground or within the clouds. In the starting stages air acts as an insulator, but after the  charges build up with the charges in the ground and cloud there will be the rapid form of electricity causes lightning. These lightning were in the color of bluish white.

Thus, the charges discharging naturally causes  lightning.

K.E =1÷2M×V^2

= 1÷2×0.05×(400)^2

= 4000

Explanation:

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

I'm not too sure

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

Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. Conductors need to be surrounded with insulators so the electrons can only go in one direction.

Explanation:

Answer:Im pretty sure its the second one because sound sometimes bounces back and that causes echo and it doesnt travel in one line or direction

Explanation:

Answer:

0

Explanation:

Defining velocity :

Velocity is a vector which is the ratio of a person's total displacement with time.

Displacement, in simple terms refers to the distance between an individual's initial position to his final position.

Man's initial position = House

After all his navigation and points covered irrespective of the distance ;

Final position = House

Hence, we can conclude that the man's Displacement is ;

Final position - Initial position = 0

Hence,

Velocity = Displacement / time taken

Velocity = 0 / 3

Velocity = 0

The answer is B. Circulatory

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.

Answer:

the smallest radius of the circular path is 8.1 km

Explanation:

The computation of the smallest radius of the circular path is given below:

Given that

V = Velocity = 201 m/s

a_c = acceleration = 5 m/s^2

radius = ?

As we know that

a_c = V^2 ÷ r

5 = 201^2 ÷ r

r = 201^2 ÷ 5

= 8,080.2 g

= 8.1 km

Hence, the smallest radius of the circular path is 8.1 km

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
