Answer:

DMM should be placed in the series combination with the circuit.

Explanation:

DMM is the digital multi meter. It can measure the voltage, current and resistance at a time.

While measuring the current with the DMM you must be ensure that the DMM should be connected with the circuit in series combination. So that it will give the resultant current accurately.

While measuring the voltage the observer should check the open probes.

In the simple Bohr model of the eighth excited state of the hydrogen atom, the electron travels in a circular orbit around a fix

Ksju [112]

Answer:

Net force on electron will be $12.568\times 10^{-12}N$

Explanation:

We have given that the orbit $r=4.28\times 10^{-9}m$

Speed of the electron $v=2.43\times 10^5m/sec$

Mass of the electron is given as $m=9.11\times 10^{-31}kg$

Centripetal acceleration is given by $a_c=\frac{v^2}{r}=\frac{(2.43\times 10^5)^2}{4.28\times 10^{-9}}=1.3796\times 10^{19}m/sec^2$

Force is given by F = ma

So force $F=9.11\times 10^{-31}\times 1.3796\times 10^{19}=12.568\times 10^{-12}N$

Why on earth the sky is in blue colour but it is black on the moon?

Damm [24]

This is beacuse it is caused by light scattering of light in the atmosphere. When the moon rises blue light is caused and scattered also caused by earth's atmosphere and it is black on the moon as there is no lunar atmosphere , so no light scattering.

Explain why 15yr old need more calcium than adults

Tom [10]

Answer:

When adolescents get enough calcium during the teen years, they can start out their adult lives with the strong bones and significantly reduce their risk for fractures as an adult. Inadequate calcium intake during adolescence and young adulthood puts individuals at risk for developing osteoporosis later in life.
