The direction would be dependent on the direction of the current through the circuit. But for this, you can use the right hand rule to determine the direction of the magnetic field. <span>The </span>right hand rule<span> states that: to determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the </span>right hand<span> in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.</span>
Answer:
Temperature reduces the wind speed on earth.
<u>Explanation:</u>
- Wind speed is an atmospheric quantity that causes the wind to flow from high to low level due to a change in temperature.
- Wind speed is controlled by the pressure gradient factor and it increases the wind speed with increase in pressure gradient.
- Wind speed decreases with an increase in temperature value as it absorbs the heat developed in the system and wind gets slowed down.
- Wind speed is measured in velocity and anemometer is used to measure the rate of wind speed.
Answer:
The wavelength is
The frequency is
Explanation:
Given that,
Distance between slits d= 0.044 mm
Distance between fringe and center of the pattern y= 8.1 cm
Distance between slits and fringes D = 6.40 m
We need to calculate the wavelength
For constructive interference
Put the value into the formula
We need to calculate the frequency
Using formula of frequency
Hence, The wavelength is
The frequency is
The answer for the following problem is mentioned below.
The option for the question is "A" approximately.
- <u><em>Therefore the elastic potential energy of the string is 20 J.</em></u>
Explanation:
Given:
Spring constant (k) = 240 N/m
amount of the compression (x) = 0.40 m
To calculate:
Elastic potential energy (E)
We know;
<em>According to the formula;</em>
E = × k × x × x
<u>E = </u><u> × k ×(x)²</u>
where;
E represents the elastic potential energy
K represents the spring constant
x represents amount of the compression in the string
So therefore,
Substituting the values in the above formula;
E = × 240 × (0.40)²
E = × 240 × 0.16
E = × 38.4
E = 19.2 J or approximately 20 J
<u><em>Therefore the elastic potential energy of the string is 20 J.</em></u>
