Answer:
Explanation:
We are given that
d=0.23 mm=
Screen is placed from the slits at distance ,L=4.75 m
The bright interference fringes on the screen are separated by 1.56 cm.
1 m=100 cm
We have to find the wavelength of laser light.
We know that
Substitute the values
The correct answer is option C. insulator.
An insulator material<span> has a high resistivity and prevents the movement of electrons. It is a hindrance in the path of electrons & resists the current flow.
The conductor conducts electrons as it offers very less resistance. A battery provides voltage to the circuit.
Hence, option (c) is correct. </span>
Mass of the Sun = <span>1.989 × 10^30 kg

the aluminum would have the most mass
Answer:
<h2>
200m/min</h2>
Explanation:
The formula for calculating distance covered = Speed * time
If Maggie completed a 10000-m race at an average speed of 160
m/min, the the time taken by Maggie to complete the race will be expressed as;
Time = Distance/Speed
Time = 10000/160
Time = 62.5 minutes
If it took Tom 12.5 fewer minutes to complete the race, then the time taken by tom to finish the same race will be 62.5 - 12.5 = 50minutes.
To get Tom's average speed, we will use the same formula as above;
From Distance = Speed * Time
Speed = Distance/Time
Since both of them completed the same distance, distance covered by Tom is also 10000m
Tom's speed = 10000/50
Tom's speed = 200m/min
<em>Hence Tom's average speed is 200m/min</em>
