5 0

Answer:

500 m/s

Explanation:

Speed of wave = Frequency × Wavelength

Speed of wave = 50 Hz × 10 m

Therefore the speed is 500 m/s

Which form of energy does a plant store when light is transformed during photosynthesis into sugars?
AlexFokin [52]

Answer:

C. Chemical energy

Explanation:

The different types of energy listed in this question are:

A) Electrical energy: it is the energy related to the flow of electrical charges (current)

B) Nuclear energy: it is the energy contained in the nuclei of the atoms, and released during nuclear reactions

C) Chemical energy: it is the energy contained in the bonds between molecules, and it is released during chemical reactions

D) Thermal energy: it is the energy associated with the motion of molecules

Photosynthesis is the process that plants use to transform the light energy (coming from the Sun) into chemical energy. In fact, in this process, plants absorb CO2 (from the atmosphere) and solar energy (from the light), and they convert them into sugars (glucose) and oxygen. Therefore, the initial energy coming as solar energy is converted into energy of the bonds of the molecules of glucose (so, chemical energy).

So, the correct option is C).

A car is moving at a initial velocity of 20 meters per second accelerates at a rate of 1.5 meters per second squared for 4 secon
Brrunno [24]
Answered using calculus.
Antidifferentiated the acceleration to get velocity. Added variable c as we do not know if there was an extra number there yet.
Knowing that when time is 0, the velocity is 20, we can substitute those numbers into the equation and find that c = 20.
Now we have full velocity equation: v = 1.5t + 20
Now we substitute 4 into t to find out the velocity after 4 seconds. This gives us the final answer of 26m/s
