Answer:

The value of d is 20.4 m.

(C) is correct option.

Explanation:

Given that,

Initial velocity = 20 m/s

Final velocity = 0

We need to calculate the time

Using equation of motion

v = u+gt

Where, u = Initial velocity

v = Final velocity

Put the value into the formula

t = \dfrac{20}{9.8}

t= 2.04\ sec

We need to calculate the distance

Using equation of motion

s = ut+\dfrac{1}{2}gt^2

s=0+\dfrac{1}{2}\times9.8\times(2.04)^2

s=20.4\ m

Hence, The value of d is 20.4 m.

Nata [24]

Answer:

The energy absorbed by the atomic electrons in the mercury atom is 7.84 \times 10^{-19} J

Explanation:

Given:

Potential V = 4.9 V

According to the conservation law,

   Loss in kinetic energy = Gain in potential energy

Here, energy absorbed by the atomic electrons is given by,

    E = eV

Where e = 1.6 \times 10^{-19} C       ( charge of electron )

    E = 1.6 \times 10^{-19 } \times 4.9

    E = 7.84 \times 10^{-19} J

Therefore, the energy absorbed by the atomic electrons in the mercury atom is 7.84 \times 10^{-19} J

A transformer consists of a 500 turn primary coil and a 2000-turnsecondary coil. If the current in the secondary is 3.0A, what i
Neporo4naja [7]

Answer:

The correct solution will be "12.0 A".

Explanation:

The given values are:

N_p= 500 \ turn

N_s= 200 \ turn

I_s= 3.0 \ A

By using the transformer formula, we get

⇒ \frac{N_p}{N_s}  =\frac{I_s}{I_p}

⇒ I_p = I_s\times \frac{N_s}{N_p}

On substituting the given values, we get

⇒      =3.0 \ A\times \frac{2000}{500}

⇒      =12.0 \ A

Which is not a step of the scientific method?
Dahasolnce [82]
The six steps of the scientific are:
1. State the question
2. Conduct research
3. Create a hypothesis
4. Perform the experiment
5. Analyze the data
6. Conclusion

So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
