Answer:

<h2>The hypothesis could be</h2><h3>The height a rocket will launch is directly propotional with the amount of baking soda added to vinegar.</h3>

Explanation:

A hypothesis is a supposition based on limited information. It's the starting point of a research,

So, in this case, Billy and Bob want to know if the amount of baking soda added to vinegar will affect the height a rocket will launch, their hypothesis is based on that.

The hypothesis could be

  • The height a rocket will launch is directly propotional with the amount of baking soda added to vinegar.

Such hypothesis is relating both variables, specifically, it's stablishing a direct proportion, which means, the more soda with vinegar, more height will be.

Big Ben, a large artifact in England, has a mass of 1x10^8 kilograms and the Empire State Building 1x10^9 kilograms. The distanc
TiliK225 [7]

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;

F=G \times \dfrac{M_{1} \times M_{2}}{r^{2}}

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;

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}

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

In a race, you run 3000 meters east in 21 minutes. What is your velocity in km/min?
STALIN [3.7K]

velocity = distance / time      v= d/t          firstly you change 3000 m into km     distance  D = 3000/1000  = 3 km             secondly   time t = 21 min      using velocity formula v = d/t       = 3 km/21min       =0.142km/min

Two boxes (24 kg and 62 kg) are being pushed across a horizontal frictionless surface, as the drawing shows. The 36-N pushing fo
defon

Answer:

F = 26.04 N

Explanation:

As we know that system of two boxes are moving on frictionless surface

So here if two boxes are considered as a system

then we have

F = (m_1 + m_2) a

m_1 = 24 kg

m_2 = 62 kg

F = 36 N

36 = (24 + 62) a

a = 0.42 m/s^2

Now since we know that both the boxes are moving together so force applied by first box on other box is given as

F = ma

F = (62 \times 0.42)

F = 26.04 N

How do scientific tests help determine the properties of substance?
Maurinko [17]

There are various properties which are exhibited by substances like physical properties,chemical properties,magnetic properties,electric properties etc.

By simply observing the substance we can not get any idea about the property of a substance.One has to conduct various tests in order to reach at his or her conclusion. The scientific tests provides a better understanding about the nature of substance and the changes that happen under various conditions and parameter.
