Answers

Answer 1

Answer: Nicolaus Copernicus spearheaded the idea of heliocentrism, that is, that the sun was the center of the solar system. Back in his time, a lot of astronomers and scientists believed that the earth was the center of the solar system. This so called belief was called geocentrism. Nicolaus was one fo the first few who pushed heliocentrism.

Answer 2

Answer:

Answer:

B. Sun was the center of the solar system.

All atoms of the same element must have the same number of

Answers

Explanation:

Atomic number is defined as the total number of protons present in an element.

Each element of the periodic table has different atomic number because each of them have different number of protons.

For example, atomic number of Na is 11, and atomic number of Ca is 20.

On the other hand, atomic mass is the sum of total number of protons and neutrons present in an atom.

For example, atomic mass of nitrogen is 14 that is, it contains 7 protons and 7 neutrons.

Thus, we can conclude that all atoms of the same element must have the same number of protons.

Answer: Protons

Explanation: The number of protons corresponds to the atomic number.

In a closed system, a cart with a mass of 1.5 kg is rolling to the right at 1.4 m/s, while another cart of mass 1.0 kg is rolling to the left at the same speed. What is the total momentum of the system of two carts?a. 0.0 kgm/s

b. 0.50 kgm/s

c. 0.70 kgm/s

d. 3.5 kgm/s

Answers

Answer: The correct option is (c.).

Explanation:

Mass of the cart A= 1.5 kg

Velocity of Cart A = 1.4 m/s towards right

Mass of the cart B = 1.0 kg

Velocity of Cart B = 1.4 m/s towards left

Momentum (P)= Mass × Velocity

$P_A=1.5 kg* 1.4 m/s=2.1 kg m/s$

$P_B=1.0 kg* (-1.4m/s)=-1.4 kg m/s$

(Negative sign means velocity of the cart is in opposite direction of that of the cart A)

Total Momentum = $P_A+P_B=2.10 kg m/s-1.40 kg m/s=0.70 kg m/s$

Hence, the correct option is (c.).

the momentum is equal to m*v
m is mass
v is speed
so 1.5 kg*1.4m/s + 1 kg*1.4m/s
2.5kg*1.4m/s
3.5 kgm/s
hope it helps

The earth's four main spheres continuously interact to support life and balance Earth's materials. When plants absorb carbon dioxide for photosynthesis, it is an example of _____ and _____ sphere interaction.biosphere, lithosphere; biosphere, atmosphere; hydrosphere, lithosphere; or cryosphere, lithosphere biosphere, lithosphere biosphere, atmosphere hydrosphere, lithosphere cryosphere, lithosphere

Answers

The correct answer for the question that is being presented above is this one: "biosphere, atmosphere." The earth's four main spheres continuously interact to support life and balance Earth's materials. When plants absorb carbon dioxide for photosynthesis, it is an example of biosphere and atmosphere sphere interaction.

Its "biosphere and atmosphere" because photosynthesis comes from the plants and the atmosphere then consumes the carbon.

A very small 100-g object is attached to one end of a massless 10-cm rod that is pivoted without friction about the opposite end. The rod is held vertical, with the object at the top, and released, allowing the rod to swing. What is the speed of the object at the instant that the rod is horizontal?

Answers

Answer:

1.40071 m/s

Explanation:

m = Mass of object = 100 g

v = Velocity of object

h = Height of drop = 10 cm

g = Acceleration due to gravity = 9.81 m/s²

Here, the loss of potential energy is equal to the gain in kinetic energy as energy is conserved

$mgh=(1)/(2)mv^2\n\Rightarrow gh=(1)/(2)v^2\n\Rightarrow v^2=2gh\n\Rightarrow v=√(2gh)\n\Rightarrow v=√(2* 9.81* 0.1)\n\Rightarrow v=1.40071\ m/s$

The speed of the object at the instant that the rod is horizontal is 1.40071 m/s

Suppose for your cookout you need to make 100 hamburgers. You knoe that 2.00 pounds will make 9 hamburgers. How many pounds will u need?

Answers

The cook needs to make 100 hamburgers. The price of 9 hamburgers is 2 pounds. Then 22.2 pounds are needed to bring 100 hamburgers.

What are methods of finding price values ?

There are simple mathematics to find the price of a material based on the data we have on it. For example if we know the price of one unit of that material then multiply the price by the number of units we want to buy.

If know the price of a bulk or certain number of materials, then find the price of one material from it.

Here, the price of 9 hamburgers is given 2 pound. Then, the price of one hamburger is :

2/9 = 0.22.

Now, multiply the value of one hamburger with the number that we want. We want 100 hamburgers. Then,

100× 0.22 = 22.2 pounds.

Therefore, 22.2 pounds are needed for 100 hamburgers.

#SPJ2

if
2.0 pound will make 9 hamburgers
so 100 hamburgers will make by pounds = 100/9 × 2.0 = 22.2 pounds

the ans is (22.22 pounds will make 100 hamburgers)

Which statement best describes the difference between moving and fixed position pulleys-Moving pulleys are attached to the object and are stationary. Fixed-position pulleys are connected to a fixed point and do not move

-moving pulleys are attached to the object and move with the object. Fixed-position pulleys are connected to a fixed point and do not move

-moving pulleys are easier to use than fixed position pulleys

-moving pulleys have more force than fixed-position pulleys

Answers

The answer is moving pulleys are attached to the object and move with the object. Fixed-position pulleys are connected to a fixed point and do not move
