The earth revolves around the sun due to _____ force between them

Answer:

(1)

H² = B² × L²

H² = (9.2)² × (5.2)²

H² = 84.64 × 27.04

H² = 2288.6656

H = √ 2288.6656

H = 47.84

Answer:

Use Pythagorean theorem

19) A² + B² = C²

5.2² + 9.2² = C²

C = √111.68

C = 10.567875...

C ≈ 10.6

21) A² + B² = C²

B² = C² - A²

B² = 7.2² - 5.3²

B = √23.75

B = 4.873397...

B ≈ 4.9

Given information:

Mass of the ice (m) = 2.0 kg

Heat transfer rate (Q/T) = 793.0 kW

Latent heat of fusion of ice (Lf) = 334 kJ/kg

[tex] \frac{Q}{T} = \frac{mLf}{T} [/tex]

Substituting the corresponding values we have:

[tex]793.0 kW= \frac{2.0kg(334 kJ/kg)}{T} \\ T = \frac{2.0kg(334 kJ/kg)}{793.0kW} = \frac{668kJ}{793kW} \\ = 0.84s[/tex]

Answer:

Electricity

Explanation:

Answer:

30 m/s

Explanation:

0^2= Vi^2+ 2 (-45)(10)

The original speed of the car is equal to 30m/s which can be calculated from the third equation of motion.

Equations of motion explain the basic concept of motion such as the position, velocity, or acceleration of an object several times. These three equations of motion can be governed by the motion of an object in 1D, 2D, and 3D.

There are three equations of motion that can be used to find displacement(s), velocity (v or u), time(t), and acceleration(a). The third equation of motion can be represented as follows:

v² = u² + 2aS

Given, the car is deaccelerated by 45m/s².

The distance covered by the car before it stops, S = 10 m

The final velocity of the car, v = 0 as it comes to rest.

We have to calculate the initial velocity of the car by using the third equation of motion:

(0)² = (u)² + 2 (-45) × (10)

u²= 900

u = 30 m/s

Therefore, the original speed of the car is 30 m/s.

Answer:

The length of the arrow tells you the size of the quantity in the vector diagram.

The direction of the arrow simply tells you the direction

Answer and Explanation:

A vector in this sense is a thing that has both magnitude (length) and direction.

Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.

This doesn't give any information about where you started or any information about where you ended up after those 2 hours.

This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.

Velocity is a vector.

Look on a map at where you are right now. Call that the center of the circle. Draw the circle with a 10 mile radius around where you are now.

The length of the arrow represents all of the possible places you could be after a two hour walk.

Which direction the arrow was pointing is what allows your friends to meet you there without checking along a ~63 mile path to find you or searching ~314 square miles to find you if you slowed down or stopped off along the way.

Distance = 2000m

Time = 35 minutes = 35×60 sec = 2100 sec

We know, Speed = Distance/Time

Therefore, Speed

Capicity of the septic tank is :

(i) capicity = 24 m³

(ii) capicity = 24 × 1000000 = 24000000 litres (cm³)

From the table shown we can see that the substance that has a density of 10.50g/cm³ is Silver. Hence the required substance is silver

Density is the ratio of the mass of an object to its volume. Mathematically,

Density = Mass/Volume

Given the following from the question

Mass = 273g

Volume of water = 26mL

Convert the volume to cm³

1ml = 1cm³ Hence;

26mL = 26cm³

Get the density of the object

Density = 273g/26cm³

Density = 10.50g/cm³

Hence the required density is 10.50cm³. From the table shown we can see that the substance that has a density of 10.50g/cm³ is Silver. Hence the required substance is silver

vi = 50 m/s

vf = 0

a = - 9.81

t = ?

Formula

t = (vf - vi)/a

Solution

t = (0 - 50)/-9.81

t = 5.097

Notice that a is made into a minus. It does not mean subtract. It means that the direction of the projectile and gravity must go in opposite directions. You will find that direction is a critically important consideration in physics.

Answer:

It'd take it 5.10 seconds

Explanation:

At the top of the launch, it is maximum height, h

formular derivation :

At maximum height, final velocity, v is zero

From first newtons equation:

[tex]{ \sf{v = u + gt}}[/tex]

v is the final velocity

u is the initial velocity

g is acceleration due to gravity

t is the time taken

but v is zero:

[tex]0 = u + gt \\ gt = u \\ t = \frac{u}{g} [/tex]

since it is vertical motion, u = usin(theta), where angle is 90°

[tex]{ \boxed{t = \frac{u \sin( \theta) }{g} }}[/tex]

t is the time taken to reach the top of the launch:

substitute, taking g to be 9.8 m/s²

[tex]t = \frac{50 \times \sin(90 \degree) }{9.8} = \frac{50}{9.8} \\ \\ { \boxed{ \boxed{time = 5.10 \: seconds}}}[/tex]

A physical change is a change affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.
