Answer:

A Graduated Cylinder has a limited round and hollow shape with each stamped line demonstrating the volume of fluid being estimated. While they are commonly more exact and exact than lab flagons and recepticles, they ought not be utilized to perform volumetric examination.

A strip of copper 370 μm thick and 4.5 mm wide is placed in a uniform magnetic field B with arrow of magnitude 0.30 T, with B wi

777dan777 [17]

Explanation:

The given data is as follows.

Magnetic field (B) = 0.30 T

Current (I) = 24 A

n = $370 \times 10^{-6} m$

charge on electron (e) = $1.602 \times 10^{-19}$ C

Formula to calculate the potential difference is as follows.

V = $\frac{B \times I/d}{n \times e
}$

= $\frac{0.30 T \times 24 amps}{8.47 \times 10^{28} electrons/ m^{3} \times 370 \times 10^{-6} m \times 1.602 \times 10^{-19} C)}$

= $1.38 \times 10^{-6}$ V

Therefore, we can conclude that value of potential difference is $1.38 \times 10^{-6}$ V.

Answer:

5) Plant; 6) Heat; 7) never heard of chemosynthesis, sorry :(

Explanation:

A plant is the only thing in an ecosystem that uses photosyenthesis. This includes trees, algea, and grass.

80% of energy is lost as heat used in order to keep the animal warm.

I am really sorry I couldn’t help with 7!
