6 0

Answer:

Height of cliff(h) = 80 meter (Approx)

Explanation:

Given:

Time taken t = 4 sec

Gravitational acceleration = 10 m/s (Approx)

Find:

Height of cliff(h)

Computation:

h = ut + 1/2(g)(t)²

Height of cliff(h) = (0)(4) + 1/2(10)(4)²

Height of cliff(h) = 80 meter (Approx)

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).

What are disadvantages of using fossil fuels to generate electricity? Check all that apply.
laila [671]
Fossil fuels are non-renewable resources and create greenhouse gases.  While cheaper now to  burn fossil fuels, within fifty years we will run out and have to turn to other sources of energy.  Hope this helps!!!

A resistor R1 is wired to a battery, then resistor R2 is added in series. Are (a) the potential difference across R1 and (b) the
tia_tia [17]

Answer:

Explanation:

a ) Earlier emf of cell applied on R₁ but now emf will be distributed among R₁ and R₂

Potential difference on R₁ will become less .

b ) Current is inversely proportional to resistance of the circuit. As resistance increases , current will be less . So current through R₁ will become less.

c )

When resistance is added in series , they are added up to obtain equivalent resistance . So equivalent resistance R₁₂ will be more than R₁ OR R₂.
