What is the relationship between the surface tension and viscosity of a liquid?

Answer: 77.5

Explanation:

Okay so, You have 3 numbers in this equation, 170, 2, and 70.

Divide 170 by 2= 85

Add 85 + 70= 155

Now divide 155 by 2= 77, R1 = 77 1/2. You can turn 77 1/2 to 77.5

Answer: 77.5

A. Energy

Explanation:

In general, the word energy refers to a concept that can be paraphrased as "the potential for causing changes", and therefore one can say that energy is the cause of any change. The most common definition of energy is the work that a certain force (gravitational, electromagnetic, etc) can do..I really hope this helps.

How much force does a 1000kg car need to accelerate at 3m s2 to the south?

Answer- the force needed to accelerate the 1000kg car by 3m/s2 is 3000N.

Emily throws the ball at 30 degree below the horizontal

so here the speed is 14 m/s and hence we will find its horizontal and vertical components

v_x = 14 cos30 = 12.12 m/sv

x

=14cos30=12.12m/s

v_y = 14 sin30 = 7 m/sv

y

=14sin30=7m/s

vertical distance between them

\delta y = 4 mδy=4m

now we will use kinematics in order to find the time taken by the ball to reach at Allison

\delat y = v_y *t + \frac{1}{2} at^2\delaty=v

y

∗t+

at

here acceleration is due to gravity

a = 9.8 m/s^2a=9.8m/s

2

now we will have

4 = 7 * t + \frac{1}{2}*9.8 * t^24=7∗t+

2

1

∗9.8∗t

now solving above quadratic equation we have

t = 0.44 st=0.44s

now in order to find the horizontal distance where ball will fall is given as

d = v_x * td=v

x

∗t

here it shows that horizontal motion is uniform motion and it is not accelerated so we can use distance = speed * time

d = 12.12 * 0.44 = 5.33 md=12.12∗0.44=5.33m

every action has an equal and opposite reaction

Answer:

Explanation:

The momentum of an object can be found by using the formula

momentum = mass × velocity

From the question

mass = 20 kg

velocity = 4 m/s

We have

momentum = 20 × 4 = 80

We have the final answer as

Answer:

herbivores

Explanation:

Animals that eat plants exclusively are herbivores.

Animals that eat only meat are carnivores.

When animals eat both plants and meat, they are called omnivores.

A large carnivore might hunt down large herbivores such as elk and deer.

The total energy could then be written as;  Etotal = ME + Ethermal

The term energy is the refers to the ability to do work. We know that according to the first law of thermodynamics, energy is neither created nor destroyed but can be converted from one form to another.

The total energy of the system must then be the sum of all the energies that are in the system. In this case, the system has both mechanical and thermal energy.

The total energy could then be written as;  Etotal = ME + Ethermal

[Questoin 1] Volume

     "Charles's law is an experimental gas law that describes how gases tend to expand when heated." Expand = volume, so this answer is correct

[Question 2] b) move faster

     An increase in heat is an increase in energy, which is an increase in particle movement. This means that b is correct, because the particles will be moving faster

[Question 3] a) Celsius

     Charles' Law uses Celsius, so when doing Charles' Law problems you should use Celsius, aka °C

Answer:

Nikola Tesla

Serbian-American inventor

sorry if this doesn't help :(

Explanation:

Answer:

Nikola Tesla was a Serbian American inventor, electrical engineer, mechanical engineer, and futurist. He was known for his contributions to the design of the modern Alternating Current (AC) electricity supply system. He was born and raised in the Austrian Empire, studying Engineering and Physics in the 1870s without receiving a degree. His works were claimed by Thomas Edison.

Hi there!

(A)

We can solve for acceleration using the following equation:

Δd = vit + 1/2at²

The shuttle lifts-off from rest, so:

Δd = 1/2at²

Rearrange to solve for 'd':

2Δd/t² = a

2(350)/(3.5²) = 57.14 m/s²

(B)

Now, we can use this equation to solve for final velocity:

vf = vi + at

vf = at

vf = 57.14 × 3.5 = 200 m/s

(C)

Now, we can use the following equation to solve for displacement:

Δd = vt

Δd/v = t

350/200 = 1.75 sec

Answer:

I guess the acceleration would be 8 meters a second

Answer:

about 30 km

Explanation:

about 30 km

The event horizon radius of a non- rotating 10 solar mass black hole is about 30 km.

Answer:

when light goes from one medium to another, refraction is taken place. refraction is the bending of light. and the center part of the bending is called the reflected angle. the index of refraction is the measure of the bending of a ray of light when passed from one medium into another. the refracted angle is the angle between a refracted ray and the normal drawn at the point of incidence to the interface at which refraction occur.

Explanation:

I think I got all of the definitions. you can use the definitions to help you understand what you write about.

Answer:

S1 = V1 t + 1/2 g t^2      distance traveled by ball dropped

S1 = 1/2 g t^2        since ball is dropped and V1 = zero

S2 = -1/2 g t^2 + V2 t        height to which ball 2 rises in time t

S1 + S2 = V2 t     both balls at same height after time t

t = S / V2 = 21.3 / 31.2 = .683 sec

Check:

S1 = 1/2 g t^2 = 9.8 / 2 * .683^2 = 2.29 m

S2 = 31.2 * .683 - 9.8/2 * .683^2 = 19 m

Total distance traveled = 2.29 + 19 = 21.3 m

Answer:

Gravity

Explanation:

The larger the object, the bigger and more powerful its gravitational field is. That is how tides and waves are made. The moon is a bit more than 1/4 of earths size. This may seem small, but its actually VERY big considering the fact that the earth is 7,917.5 miles big in diameter. AT night, the tide is more major and waves are larger because the moon is directly above the ocean, using its gravitational force to pull at the waters. Same with any other object. If you fly over the Mir Mine, an abandoned diamoned mine in russia, that you woud be sucked into the 1,722 feet pit. If you try to jump off of a falling building, instead of leaping away, you would be pulled down with the building.

Answer:

0.20 m.

Explanation:

Given: R = 30 Ω and L = 1 m

Resistance of 1m wire is R = V/I = 30Ω/0.1A

6Ω resistor will have the same voltage drop across it as 1m wire, so we require I to be 6A. Therefore, the required length of wire  is:

L = (6A)/(30Ω) = 0.2m

The description that correctly describes the structure of an atom is as follows:

Thus, the correct option for this question is A.

The characteristics of an atom are as follows:

Atoms generally consist of three subatomic particles, i.e. electrons, protons, and neutrons. Protons are positively charged particles that are present in the nucleus of an atom along with neutral particles neutrons.

While electrons are consistently revolving in the orbitals around the nucleus of an atom. These particles are negatively charged in nature.
