Answer:
A spectroscope
Explanation:
A spectroscope is used by scientists to separate a source of light ( usually white light ) into its various compositions. i.e it is used to determine the chemical makeup of a visible source of light. hence to determine whether the red light produces photo electrons, which is a chemical makeup of visible light a spectroscope should be added to the circuit.
photo electrons are electrons emitted/ejected from a surface usually metallic surface in the form of a photoelectric effect when a source of light is shines on the surface
Answer:
v = 7121.3 m/s
Explanation:
As we know that the centripetal force for the space shuttle is due to gravitational force of earth due to which it will rotate in circular path with constant speed
so here we will have
here we know that
r = orbital radius = 6370 km + 1482 km
also we know that
now we will have
<h2>
Answer</h2>
A second container has 1000 ml of water will contan more thermal energy
<h2>
Explanation</h2>
As thermal energy can be determine as
Cp and ΔT will be same for both of the container as both have water and same temperature.
At the condition of same temeprtaure and object, the object with greater volume or mass has greater thermal energy
So,
1st container has 100ml, while 1000ml in 2nd container.
The Thermal energy of 2nd container, having 1000ml water will be greater.
Answer:
B
Explanation:
The Himalayan Mountains formed at a convergence plate boundary between the Eurasian plate and the Indian plate.
It would be hard so many factors play a role in this angle kinetic potential energy gravity positioning height weight etc.to keep something as described moving as long as possible you'd have to build it heavily enough to balance out the momentum at each climax of the swing to balance with the gravitational pull of the earth core.I'd use a material such as copper for the variable.Also the weight distribution on the variables base plays a role.Take all the into account and experiment for a while!maybe one day you could find the right proportions in every role for kinetic potential gravitational momentum and weight to keep it going forever. As said alotta factors play a huge role in this experiment <span />
