Answer:

Option (A)

Explanation:

The green plants are capable of synthesizing their own food, in the presence of sunlight, CO₂ and water, and in return, liberates food and oxygen (O₂). This process is known as photosynthesis. This process is possible due to the presence of chlorophyll pigments on the plant leaves.

These green plants are also known as producers, because they are able to generate food for the consumers.

Thus, the correct answer is option (A).

Need physics help! (there’s a picture)

Nezavi [6.7K]

Answer:

i. Subtract v₀² from both of the equation.

ii. Divide both side of the equation by 2

iii. Divide both side of the equation by (x – x₀)

a = (v² – v₀²) / 2(x – x₀)

Explanation:

v² = v₀² + 2a(x – x₀)

To solve for a in the expression above, do the following:

i. Subtract v₀² from both of the equation.

v² – v₀² = v₀² – v₀² + 2a(x – x₀)

v² – v₀² = 2a(x – x₀)

ii. Divide both side of the equation by 2

(v² – v₀²) /2= 2a(x – x₀)/2

(v² – v₀²) /2 = a(x – x₀)

iii. Divide both side of the equation by (x – x₀)

(v² – v₀²) /2 ÷ (x – x₀) = a(x – x₀)/(x – x₀)

(v² – v₀²) /2 × 1/ (x – x₀) = a

a = (v² – v₀²) / 2(x – x₀)

he "escape velocity from Earth (the speed required to escape Earth's gravity) is 2.5 x 10 miles per hour. What is this speed in

Natasha_Volkova [10]

Answer: $11.17\ \text{ m/s}$

Explanation:

Given : The escape velocity : $v=2.5\times10\text{ miles per hour}$

We know that 1 mile = 1609 meters (approx)

and 1 hour= 3600 seconds

To convert escape velocity 2.5 x 10 miles per hour into m/s , we need to multiply it by 1609.34 and divide it by 3600.

Thus, the escape velocity in m/s is given by :-

$v=2.5\times10\times\dfrac{1609}{3600}\\\\=11.1736111111\approx11.17\text{ m/s}$

Hence, the speed in m/s = 11.17

If an object of mass m1 = 0.55 ???????? is sliding without friction in the +x-direction on a level surface at a speed of ????1 =

tatiyna

Answer:

$ME = 0.14 J$

$P = 0.396 kg m/s$

Explanation:

As we know that for perfectly elastic collision total mechanical energy is always conserved

so we will have

$ME = \frac{1}{2}m_1v_1^2 + \frac{1}{2}m_2v_2^2$

$ME = \frac{1}{2}0.55(0.72^2) + \frac{1}{2}0.55(0^2)$

$ME = 0.14 J$

now we also know that total moment of the system is conserved in any collision because there is no external force on it

so we will have

$P = m_1v_1 + m_2v_2$

$P = 0.55(0.72) + 0$

$P = 0.396 kg m/s$
