Answer:
graph 1
Explanation:
When it comes to a graph showing "constant acceleration," the line should be straight and upward <em>(positive acceleration) or </em>straight and downward <em>(negative acceleration).</em> The variables for acceleration are time and velocity. The independent variable (time) should be placed on the<em> x-axis</em> while the dependent variable (velocity) should be placed on the<em> y-axis.</em> As time increases, the velocity increases the same way. It doesn't slow down or changes. This makes it constant. <u>They are also directly proportional to each other</u>. This is evident on the first graph.
Potholder should have high insulation and low conductivity, therefore the correct answer is the option B
<h3>What is insulation?</h3>
Insulation is a type of material used to create barriers to the transmission of the form of energy which either is in form of heat or electricity.
For outdoor trips in cold weather, several thin layers act as better insulating barriers for heat transfer.
The ability of an electric charge or heat to pass through a material is measured by its conductivity. A material is considered a conductor if it offers very little resistance to the flow of thermal or electric energy.
Thus, Potholders should be highly insulated and have low conductivity, therefore the correct answer is the option B

To be effective, a pot holder should have low _____. viscosity conductivity malleability density
It must be a virtual image, because this is the only kind of image it can produce.
Answer:
The angular speed is 4.22 rpm.
Explanation:
Given that,
Length of arm = 6.75 m
Mass of Europa
Diameter = 3120 km
We need to calculate the angular speed
Using formula of gravitational force
Put the value into the formula
Hence, The angular speed is 4.22 rpm.
