Answer:
The potential difference across the resistor is 250 volts.
Explanation:
The potential difference
across the ends of the resistor is given by

where
is the current through the resistor and
is is its resistance.
Now, in our case
,
;
therefore, the potential across is


Answer:
The correct answer is - 1.
Explanation:
The one cubic centimeter is equal to the one mililitter of a liquid. It is same de to the fact that volume of water that fits in a one cubic centimeter is equal to the liquid present in one mililiter of a liquid.
1 cm² = 1 ml
1 cm³ = 1 ml
Thus, the use of the both unit is interchangebly.
So , correct answer is - 1.
Answer:
No, it is impossible
Explanation:
Kinematics equation:

if height is maximum:
y=H and Vf=0
so:
<h3>

</h3><h3>

</h3>
Analysis: From the last equation we see that the maximum height depends ONLY on the initial speed. This means that if both objects reach the same maximum height, then they necessarily need to have the SAME initial velocity. If they have the same initial velocity and in order to reach the maximum height at the SAME time the only way is that they are released at the SAME TIME.
72 m/s
Explanation:
Given,
Frequency ( f ) = 6 Hz
Wavelength ( λ ) = 12 m
To find : -
Speed ( v ) = ?
Formula : -
v = f x λ
v
= 6 x 12
= 72 m/s
Therefore,
the speed of a wave with a frequency of 6 Hz and a wavelength of 12 m is 72 m/s.
