8 0

Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O 2).

Simplified reaction: C₆H₁₂O₆ (s) + 6 O₂ (g) → 6 CO₂ (g) + 6 H₂O (l) + heat

Answer:

ATP (adenosine triphosphate)

Explanation:

Cellur respiration, the energy stored in glucose is transferred to ATP.

ATP is a chemical energy that a cell can use. it is the molecule that provides energy for your cells to perform work.

arsen [322]

Answer:

$v_s =7.74\ m/s$

Explanation:

given,

Speed of sound = 343 m/s

frequency of horn = 260 Hz

the friend is approaching, the frequency is increased by the Doppler Effect. The frequency is 266 Hz

using formula

$f' = \dfrac{v}{v-v_s}f_0$

$266= \dfrac{343}{343 - v_s}(260)$

$1.023= \dfrac{343}{343 - v_s}$

$343 - v_s = 335.26$

$v_s =7.74\ m/s$

the speed of friends approaching is equal to $v_s =7.74\ m/s$

Answer:

The work done is 120000 J.

Explanation:

Given that,

Weight = 600 N

Distance = 200 m

We need to calculate the work done

Using formula of work done

$W=F\times d$

Where, F = force

d = distance

Put the value into the formula

$W=600\times200$

$W=120000\ J$

Hence, The work done is 120000 J.

schepotkina [342]

Answer:

The correct answer is 4R1

Explanation:

According to the given scenario ,the radius of the tightest curve on the same road without skidding is as follows:

As we know that

Centeripetal Acceleration is

= v^2 ÷ r

In the case when velocity becomes 2 times so the r would be 4 times

So, the radius of the tightest curve on the same road without skidding is 4R1
